Nearshore marine paleoclimatic regions, increasing zoogeographic provinciality, molluscan extinctions, and paleoshorelines, California: Late Oligocene (27 Ma) to late Pliocene (2.5 Ma) Clarence A. Hall Jr.* Department of Earth and Space Sciences, University of California, Los Angeles, California 90095-1567, USA ABSTRACT Approximately 3000 medial and late Cenozoic, nearshore, marine molluscan taxa from western California are assigned to 6 time slices (27–23, 23–17, 17–13, 13–8, 8– 5, and 5–2.5 Ma) spanning ; 25 m.y. Western California is palinspastically restored for each of the time slices by backsliding and back-rotating large fault blocks or crustal units. Marine fossil assemblages and provinces are assigned to nearshore paleoclimatic regions or water masses within palinspastically restored California. Provincial patterns are controlled by thermal regimes, not single temperature conditions. Duration of warmth is used to define nearshore, marine paleoclimatic regions. Duration of warmth is defined as a single temperature value or as effective temperature, which stands for a complete temperature regime. In addition to these primary goals, this volume is aimed at: (a) showing positive feedback mechanisms between paleolatitudinal changes in sea-surface paleotemperature gradients and changes in the diversity of marine mollusks along the California coast through time; (b) using effective temperature to define “equable” nearshore marine water masses; and (c) analyzing extinction rates among macroinvertebrate marine taxa from coastal California and the possible causes of these extinctions. The late Paleogene to Neogene faunas reflect an increase in faunal diversity related to strengthened temperature gradients, greater extremes in sea-surface temperatures, reduction in temperateness, and the development of an embayed California coastline. Periodic episodes of regional extinctions reduced the sizes of populations of nearshore mollusks; however, new species made their first appearances coeval with periods of regional extinctions.

INTRODUCTION

of index species and bracketing radiometric and associated biostratigraphic ages define these molluscan ages. Approximately 3300 taxa, primarily medial and late Cenozoic, nearshore, marine mollusks from California, are assigned to the six time slices. The latitudinal distribution of mollusks living in the eastern Pacific Ocean, and the distribution of west coast of North America fossils, primarily shallow-water marine mollusks, form the bases for assigning nearshore marine paleoclimatic regions to paleomolluscan provinces in California. Paleoclimatic

The purpose of this volume is to depict the distribution of ancient marine basins in western California for a 25 m.y. span of time and to assign inferred marine paleoclimates to those marine water masses in ancient basins of deposition. The 25 m.y. period of time is divided into six time slices of unequal duration: (1) 27–23 Ma, (2) 23–17 Ma, (3) 17–13 Ma, (4) 13– 8 Ma, (5) 8–5 Ma, and (6) 5–2.5 Ma.

regions are based on the distribution of fossils; the northern endpoint of geographic ranges of the present-day analogs of the fossils; and effective temperature (ET), duration of warmth, or the primary reproductive seasons at the northern endpoint of the geographic ranges of the modern analogs. (Note that “mollusk” is used herein when referring to invertebrate animals in the phylum Mollusca, and “mollusc” as modifying adjectives, e.g., molluscan assemblage and paleomolluscan provinces.) Smith (1919) was the first paleontologist to use the distribution of Cenozoic fossils in western North America and their modern analogs living in the eastern North Pacific Ocean to interpret marine paleoclimates and to demonstrate a southward shift of inferred marine isotherms through Cenozoic time. Although the work of Smith (1919) postdated the pioneering paleoclimatological analyses of Neogene floras of Switzerland by Herr (1859) and Bailey and Sinnott (1915, 1916), Smith’s (1919) research marked the initiation of the use of molluscan paleobiology and paleoecology to infer the marine paleoclimatology of western North America. Durham (1950a) first demonstrated that marine paleotemperatures, presumably at the same absolute latitude, declined from geological epoch to epoch. Durham (1950a) showed that there was an overall southward shift in the eastern Pacific of inferred marine paleoisotherms since the Cretaceous by using the distribution of stenothermic fossil and living genera of reef-building corals and marine mollusks. Stenothermic organisms are those that are only slightly resistant to change in temperature or that have a narrow temperature tolerance. Smith (1919) and Durham (1950a) compared fossil Cenozoic genera and species with the northern endpoints of the geographic ranges of living analogs of fossil taxa in order to arrive at their conclusions. Using the northern latitudinal endpoints of living and fossil molluscan taxa, and in some cases both the northern and southern endpoints of the geographic range, Davies (1934), Schenck and Keen (1936, 1940), Newell (1948), Hedgpeth (1957), Hall (1960, 1964b), and Valentine (1961, 1966) defined molluscan and paleomolluscan provinces and delineated their associated boundaries. This method uses the northern endpoints of the geographic ranges of a relatively large number of taxa that in turn define the northern boundary of a molluscan province. In some of the research cited, the mean minimum sea-surface temperature (SST) at the northern boundary of the molluscan province delineated both the present-day and the ancient nearshore marine climatic regions. The poleward decrease in the diversity of molluscan species has also been used as a basis for defining zoogeographic provinces, and that decrease in diversity is in response to a latitudinal temperature gradient (Valentine, 1966, 1967, 1968). Latitudinal zoogeographic diversity trends or gradients for extant mollusks were discussed, for example, by Carpenter (1866), Arnold (1903), Dall (1921), Weymouth and Thompson (1930), Weymouth et al. (1931), Schenck and Keen (1940), Newell (1948), Fischer (1960), Stehli et al. (1967), Valentine (1961, 1969), Strauch (1968, 1971), Addicott (1969a, 1970b,

1970c), Rowland and Hopkins (1971) (as a caution regarding the 1968 Strauch paper), Hall et al. (1974), Hall (1975a), Jablonski and Valentine (1981, 1990), and Roy et al. (1994, 1995, 1998). Commonly latitudinal diversity gradients or profiles, utilizing the distribution of fossil mollusks, have been used to indicate marine warming and cooling trends (e.g., Addicott, 1969a, 1970b, 1970c). Because fossil molluscan assemblages and individual fossil mollusks used in these studies are compared to or correlated with (1) mollusks living in present-day molluscan provinces, (2) present-day taxa, and (3) present-day mean minimum SSTs, which mark the northern boundaries of many present-day molluscan provinces, it is commonly assumed that many shallowwater or nearshore fossil mollusks were limited in their distribution by the same mean minimum SSTs as are present-day taxa. Zoogeographic provinces are defined commonly by the observed or known distribution of organisms. Molluscan provinces can be correlated with climatic regions and northern boundaries of molluscan provinces can be suggested to coincide with mean minimum SSTs. However, for both nearshore present-day and fossil molluscan taxa, the SST during the coldest month of the year may not be the most important factor controlling or limiting the distribution or northern zoogeographic range of many marine mollusks. Mean minimum SST conditions limiting the distribution of late Holocene molluscan taxa may not have limited the distribution of many earlier Neogene forms. Physiological changes, independent of external conditions, could have occurred in evolving fossil populations. Adaptations to changing environmental conditions could have taken place among fossil taxa (DeVries and Wells, 1990). Adult and larvae of present-day molluscan taxa are carried alive into adjoining marine climatic regions where they can survive but not necessarily reproduce (Scheltema, 1971, 1988; Zinsmeister, 1974; Jablonski, 1986). Some fossil species exhibited large latitudinal range shifts through time (Roy et al., 1995), resulting in the appearance of extraprovincial taxa. Thus, there are limitations to using the northern latitudinal endpoints of Northern Hemisphere present-day molluscan taxa to interpret past marine climates. Regardless of these possible limitations of the northern endpoint of range method to infer the location of nearshore marine paleoclimatic regions, the results using the method point to a succession of paleoclimatic or paleotemperature changes during the Cenozoic. The validity of the method is supported by the recognition of similar paleoclimatic fluctuations based on Neogene fossil floras in the Northern Hemisphere (Dorf, 1955, 1959, 1963; Becker, 1961; Wolfe and Hopkins, 1967; Van der Burgh et al., 1993; Axelrod and Schorn, 1994; Dutton and Barron, 1997). A long-standing scientific dispute regarding the role of paleoaltitude relative to regional or global climatic changes, based on paleobotanical data, was discussed by Wolfe (1971, 1992), Wolfe and Schorn (1994), Axelrod (1997), and

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines Wolfe et al. (1997). Microfossils from rocks in California and elsewhere also demonstrate that paleotemperatures in Neogene seas periodically declined, fluctuated, and rose (Ingle, 1967; Bandy, 1972; Casey, 1972; Barron, 1973, 1989; Poore, 1981; Barron and Keller, 1983); fish fossils (Jordan, 1921; David, 1943), and regional and global isotopic studies also demonstrate this (Savin et al., 1975; Shackleton and Kennett, 1975; Kennett, 1977, 1980, 1986a, 1986b; Savin, 1977; DePaolo and Ingram, 1985; Vincent and Berger, 1985; Vincent and Killingley, 1985; Capo and DePaolo, 1986; DePaolo, 1986; Miller et al., 1987; Muhs and Kyser, 1987; Woodruff and Savin, 1989, 1991; Compton et al., 1990, 1993; DePaolo and Finger, 1991; Wright et al., 1992; Flower and Kennett, 1993a, 1993b, 1993c; Schoell et al., 1994). The nearshore paleotemperatures of Neogene paleoclimatic regions and the Neogene mean minimum sea-surface paleotemperatures at the northern boundaries of nearshore paleoclimatic regions along the west coast of California were probably not those of today. For example, the latitudinal endpoints of a number of Pleistocene mollusks from the Pleistocene Californian paleomolluscan province do not coincide with their present-day latitudinal endpoints, and the mollusks show evidence of migration between Pleistocene and Holocene time (Valentine and Jablonski, 1993). Marine paleotemperatures along the coast of California fluctuated during the Pleistocene and Holocene (Valentine and Meade, 1961; Muhs and Kyser, 1987; Roy et al., 1995; Cannariato et al., 1999). Roy et al. (1995) proposed that taxon-specific environmental tolerances were responsible for the migratory responses of the molluscan species to fluctuations in paleotemperatures. Today the mean minimum SST at the northern boundary of the present-day Californian molluscan province is ;15 8C. If marine paleotemperatures fluctuated during the Pleistocene, it seems unlikely that the mean minimum SST during the entire Pleistocene Epoch was 15.0 8C at the northern boundary of the Pleistocene Californian paleomolluscan province. The 15.0 8C sea-surface isotherm would not necessarily define the northern boundary of the Pleistocene Californian paleomolluscan province (named the Verdean by Valentine, 1959) and the Pleistocene warm temperate marine paleoclimatic region. The mean minimum SST at the northern boundary of the Pleistocene Californian or Verdean paleomolluscan province and the warm temperate paleoclimatic region could have fluctuated from 18.0 or 20.0 8C to 12.0 or 13.0 8C. Muhs and Kyser (1987) inferred that ca. 85– 125 ka seawater temperatures were 2.2–3.8 8C cooler than at present. Thus, a duration of warmth or an effective temperature that would allow for molluscan species within the Pleistocene Californian paleomolluscan province to live and reproduce within a region where there were fluctuations in paleotemperatures could be a better way to define the Pleistocene warm temperate paleoclimatic region. Hall (1964b) proposed that the duration of warmth at the northern boundary of the modern-day Californian molluscan province and the warm temperate marine climatic region is a

duration during which no months are cooler than 10.0 8C during the year, and a duration of warmth when the SST is between 15.0 and 18.0 8C for four months of the year. Such a definition also could be applicable to the northern boundary of the Pleistocene warm temperate marine paleoclimatic region. Woodring et al. (1946) noted the presence of taxa in Pliocene faunas from south-central western California that today live only in seawater at northern latitudes. During Pliocene time, however, they coexisted with taxa that today are limited to southern latitudes. Should the northern or the southern latitudinal endpoints of the modern faunas be taken as representative of the sea-surface paleotemperatures in which the Pliocene fauna was living, or which maximal or minimal temperatures define the nearshore marine paleoclimate inhabited by the Pliocene fauna? One answer could be that there was a duration of warmth that allowed both the present-day cold water and the warm water taxa among the Pliocene taxa noted by Woodring et al. (1946) to occupy and reproduce in the same territory. Roy et al. (1995, p. 1071) supplied another answer and proposed the following, referring to extraprovincial Pleistocene mollusks of western North America: The latitudinal ranges of southern extraprovincial species are significantly wider on average than those of the species pool from which they were drawn, but the geographic ranges of northern extraprovincials resemble those of their parent pool. This contrast is primarily a consequence of the biogeographic structure of the eastern Pacific fauna; water-mass boundaries are more effective barriers for southern species migrating north in response to changing climatic conditions than for northern species moving south.

Durham (1950a, p. 1248) listed several dozen living taxa that are present in the eastern Pacific Ocean that he considered to be restricted to the tropics and that live in water with mean minimum SSTs of “20 8C or warmer.” In the western Pacific, however, 56% of the species of the 51 tropical genera and subgenera that Durham (1950a) listed range northward into water with mean minimum SSTs of 10.0–14.0 8C, not 20.0 8C. During the Neogene did the fossil taxa from the eastern Pacific Ocean live in water with nearshore mean minimum SSTs of 20.0 8C or 10.0 8C? Because 95%–98% of the western Pacific species within the genera analyzed by Durham (1950a) live in water where SSTs are 20.0 8C for at least four months per year, duration of warmth could better define the marine climate in which the present-day taxa live, and the nearshore paleoclimate in which the fossil taxa lived. Among the taxa listed by Durham (1950a), the winter-minimum water-mass boundary of 10.0– 14.0 8C would not seem to be an effective barrier for southern tropical genera. The present-day Gulf of California contains molluscan taxa that otherwise live in outer and inner tropical marine climatic regions along the southern outer coast of Baja California Sur, Mexico, and the west coast of Mexico (Keen, 1971). However, the modern-day outer and inner tropical mollusks described by Keen (1971) that are living in the Gulf of Cali-

fornia live in water with winter SSTs as low as 14.9 or ;15 8C, not 20.0 8C. Vaughan (1940) assigned mean minimum seawater temperatures of 22.8–25.6 8C to the marine tropics, Stephenson (1947) assigned thermal boundaries of 18.0–32.0 8C to the marine tropics, and Ekman (1953) defined marine tropics as a climatic region where temperatures are above 20.0 8C during the coldest month of the year—a definition apparently applied to molluscan faunas studied by Durham (1950a). Is a fossil fauna from western California, one that includes an assemblage of mollusks with a taxonomic composition similar to that living in the present-day Gulf of California, to be assigned to a marine paleoclimate with a minimum SST of 20.0 8C or to a temperature of ;15 8C? The answer, when analyzing fossil faunas, is likely to be neither. The molluscan fauna currently living in the Gulf of California lives in water with SSTs of 20.0 8C for 8 months of the year and 18.0 8C for 11–12 months of the year at lat 298N, even though the minimum or winter SST is ;15 8C. Note that Bernard et al. (1991) stated that the Panamic tropical molluscan fauna only reaches as far north as lat 26 8N in the Gulf of California (minimum winter temperature of 19 8C). A situation similar to that of the molluscan fauna living in the Gulf of California also exists with the distribution of present-day, reef-building corals both in the Gulf of California and along the east coast of Japan (Hall, 1964b). Zooxanthellate (endosymbiotic primary producers) corals are common in Indian, Pacific, and Atlantic Ocean tropical waters. These fossil corals are commonly considered to have lived in the tropics. Holocene zooxanthellate corals, however, range northward to lat 358 or 378N along the east coast of Japan (Rosen, 1984). The mean minimum SST at lat 358N along the Japanese coast is ;12.79 8C (U.S. Navy, Chief of Naval Operations, 1956–1958). The mean annual SST at lat 358N is 16.0 8C (Rosen, 1984), and the SST at lat 358N along the east coast of Japan is ;20.0 8C for four months of the year (Hall, 1964b). These temperature conditions suggest that it is not strictly minimal temperatures or cold water-mass boundaries that control the distribution of zooxanthellate corals. However, Veron (1995, p. 91) stated, “Very few zooxanthellate corals are known to tolerate temperatures below 11 8C under normal conditions” and “ . . . 18 8C, sustained over protracted periods of time, has survived as the identified minimum sea surface temperature to which functional [coral] reefs are normally exposed” (my brackets). In addition to depicting the distribution of late Paleogene and Neogene marine basins in western California, and assigning nearshore marine paleoclimates, defined by a range of, but not mean minimum SSTs, to those basins, my purposes herein are to (1) show that increased latitudinal sea-surface paleotemperature gradients along the coast of California were accompanied by increases in the diversity of marine mollusks, (2) define “equable” based on effective temperatures, (3) analyze extinction rates and survivorship rates among the 27–2.5 Ma macroinvertebrate marine taxa from coastal California, and (4) suggest

possible causes to account for the regional extinction of relatively large numbers of taxa during the intervals 17–13 Ma and 5–2.5 Ma. PROCEDURE The following four principal aspects relate to assigning nearshore paleoclimates to the late Paleogene and Neogene marine regions of California. Assigning rock units to time slices Upper Paleogene and Neogene marine formations were assigned to six geochrons using radiometric ages of volcanic and pyroclastic rocks interbedded or correlated with formations that contain marine macroinvertebrate fossil-bearing strata, isotopic ages of fossil shell material, fission-track ages of rocks associated with the fossil-bearing strata, and ages of microfossils within formations. Significant and relatively easily recognizable changes in marine macroinvertebrate faunas occur at the beginning and end of each of the six time intervals within upper Paleogene and Neogene marine rock sequences in California (Appendix 1, Tables A1–A6). Tables A1–A6 (Appendix 1) summarize the bases for the assignments of upper Paleogene and Neogene formations to time slices, and Table A13 (Appendix 1) lists the formations referred to in this volume and their time-slice assignments. Upper Paleogene and Neogene rock units are assigned to geologic ages based on radioisotopic dating and fission-track ages of the rocks and associated fossil shell material. They are also assigned to magnetostratigraphic ages (global polarity time scale or geomagnetic polarity sequences) or to biostratigraphic ages based on neritic foraminiferal, diatom, and calcareous plankton biostratigraphy correlated to geochronologic units and absolute ages (e.g., Berggren et al., 1995a, 1995b; see Appendix 1, Tables A1–A6). Fossil mollusks, echinoderms, and other macroinvertebrate fossils in this study are assigned to stratigraphic age ranges based on their presence in age-dated rock units (Appendix 1, Table A13). The chronostratigraphic units used in this volume are based primarily on index fossils such as pectinids (Smith, 1991a), echinoderms (Grant and Hertlein, 1938; Durham, 1955; Hall, 1962a; Durham and Morgan, 1978), and gastropod taxa (Addicott, 1970a) with narrow stratigraphic ranges (Figs. 1 and 2). The detail or precision of biostratigraphic ages based on microfossils is greater than that provided by macroinvertebrate fossils; e.g., the 17–13 Ma time slice based on mollusks includes the Relizian and Luisian ages, which are based on neritic Foraminiferida (see Smith, 1991a). The formations that contain the principal invertebrate faunas that were used to define the six time slices in this volume are annotated with the numbers 1–6 in Appendix 1 (Table A13). The stratigraphic positions of these units relative to other units with known relative and absolute geologic ages within the list were also utilized to assign formations to time slices. The age

limits of some of the time slices are rounded to a whole number. Locally, some index fossils can be correlated with absolute age dates that are slightly older or slightly younger than the upper and lower age limit of the time slice. For example, there are index species within the 27–23 Ma time slice that are locally correlated with rocks with a lower absolute age limit of 27.6 Ma, and an upper age limit of 23.5 Ma. There are species in the 23–17 Ma time slice that locally are correlated with a lower absolute age limit of 22.6 Ma, or an upper age limit of 16.5 Ma. There are also index species in the 17–13 Ma time slice that are correlated with an upper absolute age limit of 13.5 Ma. Within the 5–2.5 Ma time slice there are species that are correlated with a lower absolute age limit of 4.6 or 5.3 Ma. Smith’s (1991a) exceptional monograph on pectinids and her absolute age and biostratigraphic assignments are followed in this study; exceptions are noted in the section on biostratigraphic problems and in Figure 1. The overlapping age ranges of fossil pectinids, echinoids, and gastropods, and microfossil biostratigraphy were used to assign formations to time slices. Two examples illustrate the method. The data for both examples are in Appendix 1 (Tables A3 and A9, 17–13 Ma time slice). The overlapping age ranges of the pectinids listed under the heading of lat ;378–368N west of the San Andreas fault (Appendix 1, Table A9), i.e., ranges of 32–8 Ma, 23–13 Ma, and 18–8 Ma, produce an overlapping age range for the rock units between these latitudes of 18–13 Ma. Associated with the macroinvertebrate fauna are microfossils that have been assigned to biostratigraphic ages of Saucesian–Relizian (22.7 or 21 Ma to 15.6 Ma), Relizian (18 to 16.5 or 15.6 Ma), and Luisian–early Mohnian (16.5–13 Ma), i.e., to a maximum age range of 22.7–13 Ma or an overlapping age range of 16.5– 15.6 Ma.

The overlapping age ranges of pectinids listed under the heading of lat ;358–348N west of the San Andreas fault (Appendix 1, Table A9), i.e., ranges of 32–8 Ma, 27–17 Ma, 27–16 Ma, 23–13 Ma, 23–13 Ma, and 18–8 Ma, produce an overlapping age range for the rock units between these latitudes of 18–16 Ma. In addition to the radiometric ages of volcanic rocks associated with rocks containing macroinvertebrate assemblages, microfossils also have been used to assign ages to formations. In this case, the microfossils have been assigned to the Relizian (18–15.6 Ma) and Luisian (16.65–14 Ma) ages, i.e., to a maximum age range of 18–14 Ma or an overlapping age range of 16.5–15.6 Ma. Repeating this process, utilizing other index fossils in addition to pectinids and radiometrically dated interbedded volcanic and sedimentary rocks, the lower and upper limits of the 17–13 Ma time slice, and other time slices, are determined (Appendix 1, Tables A1–A12). Taxonomy and latitudinal endpoints of taxa Neogene marine macroinvertebrate fossils from Oregon, California, and Alta Baja California, Mexico, are assigned to the six geochrons or time slices (hereafter referred to as the 27– 23, 23–17, 17–13, 13–8, 8–5, and 5–2.5 Ma time slices), and their presence in Neogene formations from California, Oregon, and Mexico is listed in 18 of latitude (absolute latitudes) groups west and east of the San Andreas fault. For example, late Paleogene and Neogene marine macroinvertebrate fossils collected from between the absolute latitudes of 358 and 348N west of the San Andreas fault in western California were placed in one latitudinal group, and those east of the San Andreas fault at the same latitude into another. A taxonomic analysis was

made for each taxon in order to avoid errors owing to failure to recognize synonyms among the fossil taxa. The latitudinal endpoints of each living taxon were determined from the literature. The effective temperature, referring to duration of warmth or warmth (discussed in detail in the following) was calculated for each living taxon within a 18 of latitude fossil group (Appendix 1, Tables A7–A12).

Effective temperature The effective temperatures calculated for fossil taxa within a time slice, and within a latitudinal group, were grouped by ranges of ET (Figs. 3–8). Effective temperatures were used to define nearshore marine present-day climates and late Paleogene and Neogene paleoclimates (Table 1).

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines A fossil fauna was assigned to a nearshore marine paleoclimatic region within a particular time slice, and within a 18 of latitude group, on the basis of the percentage of taxa in each of the five ranges of ET (Fig. 9). Note that 18 of latitude at the latitudes of California is equal to ;113 km. The percentages of taxa in each of five ranges of ET were graphed for each degree of absolute latitude west and east of the San Andreas fault for each of the time slices (Figs. 10–19), and for each degree of absolute latitude in a single time slice (Figs. 20–27). Paleoshorelines and paleoclimatic regions Palinspastic maps of California for each of the six time slices were constructed by back slipping fault blocks along faults for which there are previously determined amounts of right and left slip, and by counterclockwise back rotating the Transverse Ranges by previously determined, westward increasing paleomagnetic vectors. (Note that the paleoshoreline maps in this study are not true palinspastic maps because shortening by folding has not been considered in the paleogeographic reconstructions.) The inferred paleoshorelines of marine basins for each of the time slices were determined from a broad spectrum of published geologic maps. (The limits of the marine basins that are depicted in this study are almost entirely inferred. Paleoshorelines are based on the known distribution of marine rocks of known age. Thus, the limits of the marine basins that are depicted could be more extensive than shown because of erosion after deposition.) Nearshore marine paleoclimatic regions were assigned to each of the marine basins (Appendix 1, Table A16, and Plate 1 for use with Plates 2–8). Each of these four phases of the study is outlined in detail in the following. Assignment of rock units to time slices Radiometric fission-track and isotopic ages of rock units were used to assign absolute geologic ages to formations and other upper Paleogene and Neogene rock units. Tables A1–A6 (Appendix 1) summarize the bases for the assignments of upper Paleogene and Neogene formations to time slices. Table A13 (Appendix 1) lists the formations referred to in this volume and their time-slice assignments, and the references used to make age assignments are listed in Appendix 2. Molluscan stages. The marine macroinvertebrate fossils in the six time slices used in this study essentially define six uppermost Paleogene and Neogene chronostratigraphic stages. However, neither existing nor new Californian molluscan stage names are assigned to these six time slices. Others have assigned formations to Californian molluscan stages and ages, but with the formational names for molluscan stage and ages. The

9

use of formational names, e.g., Vaqueros, Temblor, Santa Margarita, Jacalitos, Etchegoin, and San Joaquin, for chronostratigraphic units, e.g., “Vaqueros” and “Temblor” stages, has introduced or has the potential of introducing confusion. In addition to these names, other formational names also have been used for names of substages, e.g., the “Briones,” “Cierbo,” and “Neroly” substages of the “Margaritan” Stage. Not only is this practice confusing, but these chronostratigraphic units do not conform to the North American Stratigraphic Code (the code) (North American Commission on Stratigraphic Nomenclature, 1983). Researchers (e.g., Addicott, 1972, 1976a, 1976b; Smith, 1991a) proposed and used formational names for chronostratigraphic units. By placing their time-stratigraphic terms in quotation marks these workers intended to show that the time-stratigraphic names are provisional chronostratigraphic units. The confusion that using formational names for stage names can cause is apparent if the ages of the Temblor and Vaqueros Formations are referred to in written and in particular oral presentations. For example, the Temblor Formation ranges in age from late Oligocene to medial Miocene time, and it is assigned to both the “Vaqueros” and the “Temblor” stages, i.e., the Temblor Formation is locally “Vaqueros” in age. The Vaqueros Formation is assigned to the “Vaqueros” and “Temblor” stages. Thus, the Vaqueros Formation is in part “Temblor” in age. These two provisional molluscan stages span a period of ;20 m.y. Locally and regionally the sedimentary rocks that compose the Vaqueros and Temblor Formations were deposited over a relatively much shorter period of time than 20 m.y. However, because the usage and terminology of the provisional molluscan stages (Addicott, 1972) have become entrenched in the literature, the molluscan stage names used by others are included for reference in the tables of upper Paleogene and Neogene formations (Appendix 1, Tables A1–A6). These stages are not recognized as valid in this volume because they do not conform to the code or rules of stratigraphic nomenclature. Placing their names in quotation marks to indicate provisional stages subverts the code. Biostratigraphic problems. There are a few significant biostratigraphic problems associated with four of the six time slices, 27–23 Ma, 23–17 Ma, 17–13 Ma, and 13–8 Ma. Other biostratigraphic problems that require less detailed discussion are treated as footnotes in Tables A1–A6 (Appendix 1). 27–23 Ma time slice. The age range and faunal associations of Vertipecten perrini (Arnold) are critical when assigning fossil assemblages from the Vaqueros and Temblor Formations to a time slice. On page 2, Smith (1991a) assigned an age range to V. perrini (Arnold) of 35–27.6 Ma, and she indicated that the age range of V. perrini overlaps the age ranges of V. alexclarki Addicott, “Macrochlamis” magnolia magnolia (Conrad), and “M.” magnolia ojaiensis Smith. On page 39, Figure 12, Smith (1991a), in the same volume, presented a different age range for V. perrini, i.e., 31.2–27.6 Ma, and she showed no overlap with the stratigraphic range of V. alexclarki. Again in the same volume, Smith (1991a, p. 2, Fig. 1) assigned an age range of

35–28 Ma to V. perrini. Because she indicated that V. perrini and V. alexclarki are present together in the Vaqueros Formation (e.g., at “The Indians,” ;65 km southeast of Monterey, California), which crops out in the Santa Lucia Range (Smith, 1991a, p. 85), there could be some confusion regarding the age range of V. perrini. J.T. Smith (2000, written commun.) indicated that now she considers the age range for V. perrini to be 31.2–27.6 Ma. Smith (1991a, p. 36, Fig. 11) depicted the distribution of Zemorrian and Saucesian foraminifers and the ZemorrianSaucesian sea, as modified from Addicott (1968), and interpreted the age range of the Zemorrian and Saucesian ages to

be 32–26 Ma. She placed these ages entirely within the early “Vaqueros” Age, on the basis of the age ranges of “M.” magnolia magnolia, “M.” magnolia ojaiensis, “M.” magnolia with an intermediate rib count, and Vertipecten alexclarki. Smith (1991a, p. 2) assigned an age range of 36.6–32.5 Ma to V. alexclarki. Therefore, this species must not have directly influenced her 1991 conclusion regarding her assignment of a 32– 26 Ma age range to the Zemorrian and Saucesian ages (Smith, 1991a, Fig. 11), because V. alexclarki is older than her proposed age range for Zemorrian-Saucesian time. An age range of 32– 26 Ma is entirely within the Zemorrian Age, based on microfossils (Poore, 1980; Poore et al., 1981). However, Smith

(1991a, p. 32, 33, and elsewhere) noted that the key index species mentioned here also are present with Saucesian microfossils, and the Saucesian has an age range of ca. 23 to 17 or 15.3 Ma (Poore, 1980; Poore et al., 1981; Smith, 1991a). The age range of the late Zemorrian and early Saucesian, based on benthic foraminifers, is taken here to be from ca. 27 to 22 or possibly 20 Ma.

The youngest age of Vertipecten perrini (Arnold) is considered here to be 22 Ma. This inference is based on the presence of this taxon in sedimentary rocks that are interbedded with volcanic rocks that have been radiometrically dated as ca. 22 Ma (Turner, 1970, p. 101). The oldest geologic age of V. perrini is taken here to be 31.2 Ma, following the assignment by J.T. Smith (2000, written commun.).

Addicott (1973) restricted the age range of Vertipecten alexclarki Addicott to his “Unnamed” molluscan stage. The “Unnamed” molluscan age is older than his “Vaqueros” Stage and younger than the Refugian Stage (Addicott, 1973). The “Unnamed” molluscan stage has been assigned an age range of ca. 38–32.6 Ma, or late Eocene–early Oligocene (Smith, 1991a, p. 2). The molluscan fauna from this time slice is not considered herein.

The geographic and stratigraphic distribution of Vertipecten alexclarki is restricted. The fossil taxon is present in two regions, (1) the Vaqueros Formation, Bear Creek–Two Bar Creek, Santa Cruz Mountains (near and north of lat 378N, west of the San Andreas fault) (Burchfiel, 1964; Brabb et al., 1977), and (2) in the Wygal Sandstone Member of the Temblor Formation, or Phacoides Sand, Media Agua, Carneros, and Zemorra Creeks, Temblor Range (near lat 358308N, east of the

Note that mean effective ET of 11.97 8C between lat 408 and 418N is anomalously high considering that 75% of fauna between those latitudes have ETs of between 10.17 and 12.00 8C.

San Andreas fault) (Addicott, 1973). It is inferred that the Vaqueros Formation in the Santa Cruz Mountains, containing V. alexclarki, was offset 305 km along the San Andreas fault from the Temblor Range (Addicott, 1973). Vertipecten alexclarki is present with early Zemorrian microfossils in the Vaqueros and Temblor Formations in the Santa Cruz Mountains and Temblor Range, respectively; it is not present in rocks of Refugian Age, according to Addicott (1973). The base of the Zemorrian Stage and the top of the Refugian Stage were taken to be 36.6 Ma by Poore (1980) and Smith (1991a, p. 2), and this boundary divides the late Eocene from the early Oligocene. Kleinpell (1980, p. 17) considered the Refugian Stage to be within the latest Eocene and earliest Oligocene. The youngest age of the “Unnamed” molluscan age of Addicott (1972) is 32.6 Ma, according to Smith (1991a, p. 2). On the basis of the geographic, stratigraphic, and biostratigraphic relationships noted herein, an age range of 36.6–32.6 Ma is

assigned here to both the ranges of V. alexclarki and Addicott’s (1972) “Unnamed” molluscan stage. When Vertipecten perrini and “Macrochlamis” magnolia s.l. are present together in the same rocks, when other index species of pectinids are absent, and when V. perrini and “M.” magnolia are present together with only microfossils of Zemorrian Age, those rocks are assigned an age range of 32–27 Ma. Rocks with these pectinids and Saucesian microfossils are assigned to the 27–23 Ma time slice. Many fossil assemblages collected from the Vaqueros and Temblor Formations include V. perrini, species and subspecies of “M.” magnolia, and other index species of pectinids. In such cases it is not necessary to rely on the presence of Saucesian microfossils associated with the pectinid beds in order to assign an assemblage to its appropriate time slice because the overlapping age ranges of the index species, including V. perrini, and species and subspecies of “M.” magnolia, can be used to assign an age to the assemblage.

23–17 Ma time slice. There are significant differences between geologic ages assigned to the same formation based on fossil mollusks and benthic foraminifers. Examples of these differences are apparent within the 27–23 Ma and 23–17 Ma time slices, e.g., the differences between ages of formations based on pectinids and ages based on Foraminiferida. The sig-

nificant differences between ages based on pectinids and benthic foraminiferal ages are addressed because of the importance of pectinids as index fossils. Two examples of the marked differences between correlations using radiometric ages and faunal ages are given here to illustrate the problem of correlation between ages based on microfossils and on mollusks, and to dem-

onstrate that some of the age ranges of some of Smith’s (1991a) species of pectinids should be reevaluated. The examples are as follows. The lengthy and seemingly irreconcilable debate between those who regard or regarded the Vaqueros Formation as late

Oligocene in age, based on the larger foraminifer Lepidocyclina, and those biostratigraphers who regard or regarded the Vaqueros Formation as early Miocene, was summarized by Brabb et al. (1983), who sought to reconcile the differences with the discovery of planktic foraminifers and calcareous nanno-

(1985a) assigned the N7 zone an age range of 17.5–16.6 Ma, within the Relizian Age. The Relizian Stage is based on benthic foraminifers (Poore, 1980; Poore et al., 1981).

L. miguelensis (Arnold), and Vertipecten nevadanus (Conrad) is present with the microfossil assemblage described by Brabb et al. (1983, p. 167, 174). Smith (1991a, p. 2, 77–79) taxonomically reassigned Lyropecten bowersi to Vertipecten bowersi (Arnold) and assigned the species to an age range of 23–19.5 Ma or 23–18 Ma. She assigned Lyropecten miguelensis to an age range of 23–19 Ma or 23–18 Ma, and to late Zemorrian to late Saucesian ages, ages based on benthic foraminifers (Poore, 1980; Poore et al., 1981). Smith (1991a, p. 82) taxonomically reassigned Vertipecten nevadanus to V. kernensis (Hertlein), a pectinid that is present at the Lepidocyclina locality referred to by Brabb et al. (1983), and she assigned an age range of 27.6–23 Ma (i.e., within the Zemorrian Age; Poore, 1980; Poore et al., 1981). The two overlapping age assignments of the pectinids, based on Smith’s (1991a) age assignments, indicate an age of 23 Ma (late Zemorrian Age) for

Latitude indicates degrees of absolute latitude west and east of San Andreas fault; e.g., 34 WSA represents absolute latitudes between 34 8 and 33 8N west of San Andreas fault. Percentage indicates percentage of fauna with effective temperature (ET) range. If 30% of fossil fauna has ET range of between 18.44 and 27.65 8C, fauna is considered to have lived in inner tropical paleoclimatic region. If 28%–44% of fossil fauna has ET range of between 19.98 and 27.65 8C, and if another 28%–35% of fossil fauna has ET range of between 16.98 and 17.90 8C, fossil fauna is considered to have lived in outer tropical paleoclimatic region; if 13%–33% of fossil fauna has ET range of between 16.98 and 27.65 8C, and if another 28%–54% of fossil fauna has ET range of between 15.51 and 16.78 8C, fossil fauna is considered to have lived in warm temperate paleoclimatic region. If 13%–42% of fossil fauna has ET range of between 15.51 and 27.65 8C, and if another 48%–67% of fossil fauna has ET range of between 10.0 and 11.81 8C, fossil fauna is considered to have lived in temperate paleoclimatic region; and if 75% or more of fossil fauna has ET range of between 10.17 and 12.0 8C fossil fauna is considered to have lived in cool temperate paleoclimatic region. Fossil assemblages at all absolute latitudes in 27–23 Ma time slice lived in nearshore outer tropical paleoclimatic region. (For abbreviations and definitions see Figs. 3 and 9; Table 1.)

the Lepidocyclina beds, in contrast to the ca. 17 Ma age or Relizian Age assignment of Brabb et al. (1983) based on microfossils. There is an age discrepancy of 6 m.y. or more between the molluscan and microfaunal ages. The index species Vertipecten kernensis (Hertlein) is also present at the base of the Jewett Sand in the San Joaquin Valley; it is an index species that Smith (1991a, p. 2) restricted to an age range of 27.6–23 Ma. Olson (1988) assigned the base of the Jewett Sand to an age of 23 5 1 Ma based on strontium isotope dates from pectinids at the base of the Jewett Sand. Olson (1988, p. 192) stated, “the Zemorrian-Saucesian boundary occurs within the lower part of the Jewett Sand and Freeman Silt system (Bartow and McDougall, 1984).” The ZemorrianSaucesian boundary is between 22.5 and 21 Ma (Smith, 1991a, p. 3). Smith (1991a, p. 2) placed Olson’s (1988) age date of 23 5 1 Ma at the upper limit of the age range of Vertipecten

kernensis (Hertlein). However, Addicott (1965b, p. C103) indicated that Vertipecten nevadanus (4 V. kernensis) ranges upward from the basal Jewett Sand into the lower Olcese Sand, and possibly into the middle Olcese Sand. Olson (1988, p. 193) stated that the lower Olcese Sand is “at least older than 18 5 1 Ma.” The youngest age of Vertipecten kernensis must be younger than 23 Ma, because V. kernensis is present above the base of the Jewett Sand and in the overlying lower Olcese Sand. Olson (1988, p. 193) also stated, “The pumiceous sandstone near the top of the middle Olcese Sand may be as old as 17.2 Ma and the Ostrea titan bed near the base of the upper Olcese Sand may be as young as 17 Ma.” Bartow and McDougall (1984) assigned a fission-track age of 15.1 5 1.7 Ma to the pumiceous sandstone of the middle Olcese Sand. Olson (1988) assigned an age of 16.7 Ma to the upper Olcese Sand. On the basis of the molluscan distributional data of Addicott (1965b,

Figure 21. Paleoclimate at various degrees of absolute latitudes west (WSA) and east (ESA) of San Andreas fault, 23–17 Ma. (For abbreviations and definitions see Figs. 3, 9, and 20; Table 1.) Based on percentages outlined in caption for Figure 20, fossil fauna from between lat 44 8 and 43 8N east of San Andreas fault lived in warm-temperate paleoclimatic region, while all other fossil assemblages from other latitudes lived in outer tropical paleoclimatic region.

p. C103) and the analyses of Olson (1988, p. 193), the youngest age of V. kernensis is here taken to be 17 Ma, not 21 Ma. The Lepidocyclina beds described by Brabb et al. (1983) are assigned here to the 23–17 Ma time slice, and the age assignment of the Lepidocyclina beds by these authors is followed here. The age assignments of the rock units noted here and based on microfossils and molluscan fossils are brought into alignment when the age range of Vertipecten kernensis is extended to 17 Ma (complete range of 27.6 or 27 to 17 Ma). A second example of a mismatch between age assignments based on mollusks and microfossils is related to fossils within the Vaqueros or Temblor Formations of the southern San Joaquin Valley. Hoots (1930, p. 261) reported the presence of Pecten perrini Arnold from what he called the Vaqueros Formation, located in the southernmost part of the San Joaquin Valley (near lat 358N and east of the San Andreas fault). Nilsen (1987a) assigned these rocks to the Temblor Formation, and to an age range from early or medial “Vaqueros” Age (ca. 25 Ma) to an early Saucesian Age (ca. 22.5 Ma). Smith (1991a, p. 85) reassigned Pecten perrini to Vertipecten perrini (Arnold). She assigned V. perrini to the “lower ‘Vaqueros’ Stage,” to an age range of 35–27.6 Ma (Smith, 1991a, p. 2), and to an age range of 31.2–26.5 Ma (p. 39) (i.e., to a middle Zemorrian Age; Poore, 1980; Poore et al., 1981). As mentioned previously,

Smith (2000, personal commun.) now considers the age of V. perrini to be 31.2–27.6 Ma. When pectinid and foraminiferal age assignments for these rocks are compared, there is a maximum age difference of 15 m.y., and a minimum difference in age of 4 m.y. Taking the averages of all of the age assignments, there is an average difference between the age assignments of 8.8 m.y. Smith (1991a, p. 85) noted that Vertipecten perrini is present in sandstone beds below basalt in the Temblor Formation described by Nilsen (1987a). The basalt was assigned an age of 21.5 5 0.7 Ma by Turner (1970). Thus the specimen of V. perrini associated with these rocks could be as young as 22 Ma, not 27.6 Ma. Bruclarkia barkeriana (Cooper) is also reported from the Temblor Formation in the southernmost part of the San Joaquin Valley, and it is present with Vertipecten perrini (Hoots, 1930, p. 261). Addicott (1965b, 1970a, p. 90) assigned B. barkeriana to a stratigraphic range from the basal Jewett Sand upward to the Round Mountain Silt. It is not present in the grit zone below the basal Jewett Sand, nor is it present with “Macrochlamis” magnolia. Olson (1988) placed the base of the Jewett Sand as ca. 23 Ma, and assigned the Round Mountain Silt to an age of ca. 17 Ma. However, based on the overlapping age ranges of seven species of pectinids from the rocks mapped by Hoots

Figure 22. Paleoclimate at various degrees of absolute latitudes west (WSA) and east (ESA) of San Andreas fault, 17–13 Ma. (For abbreviations and definitions see Figs. 3, 9, and 20; Table 1.) Based on percentages outlined in caption for Figure 20, fossil faunas from between lat 398 and 378N east of San Andreas fault and from between lat 388 and 368N west of San Andreas fault lived in warm temperate paleoclimatic region, and all other fossil assemblages at other latitudes lived in outer tropical paleoclimatic region.

(1930) and Nilsen (1987a), these rocks and associated fossils are assigned here to the 27–23 Ma time slice. The seven species of pectinids are Chlamys sespeensis (32–23 Ma or 32–17? Ma), Lyropecten pretiosus (27–22 Ma), “Macrochlamis” magnolia magnolia (32–17 Ma), “M.” magnolia ojaiensis (30–23 Ma), Pacipecten andersoni barkerianus (27–17 Ma), Vertipecten kernensis (27–17 Ma), and V. perrini (31.2–22 Ma). Based on the upward extension of the age range of Vertipecten perrini to 22 Ma (complete age range of 31.2–22 Ma), and the preceding analysis, the fossils listed by Hoots (1930) are placed in the 27–23 Ma time slice. The shale facies of Dibblee (1993b, 1993c, 1993d), Rincon Shale of Fritsche (1993), Topanga Formation in the western Santa Monica Mountains of Dibblee (1993b, 1993c, 1993d), Topanga Canyon Formation in the western Santa Monica Mountains of Fritsche (1993), and the “Unnamed” sandstone of Fritsche (1993) are assigned to the 23–17 Ma time slice. 17–13 Ma time slice. The 17–13 Ma time slice can locally, but rarely, include latest early Miocene fossils. Some volcanic

rocks in the time slice are as old as 18 Ma (see Appendix 1, Table A2). The lower part of the Lospe Formation is composed of alluvial and fan-delta deposits. The upper part of the formation consists of lacustrine and shallow-marine deposits. Tuff (dated as ca. 17 Ma) is interbedded with alluvial and lacustrine deposits: on the basis of this age, microfossils from the Lospe Formation are assigned an age of ca. 17 Ma. Poore et al. (1981, p. 30) considered the Relizian Stage at its type locality to be “at least 18 to 17 Ma,” and remarked that “the Relizian Stage should be considered early Miocene rather than middle Miocene” in age. They correlated the type Relizian Stage with the N7 planktic foraminiferal zone. Berggren et al. (1985b, p. 1416) correlated the N7 planktic foraminiferal zone with a geochronometric age of 17.6–16.6 Ma, and the latest early Miocene. Thus, the 17–13 Ma time slice ranges in age from latest early to medial Miocene time. The Topanga Formation in the eastern Santa Monica Mountains of southern California is included in the 17–13 Ma

Figure 23. Paleoclimate at various degrees of absolute latitudes west (WSA) and east (ESA) of San Andreas fault, 13–8 Ma. (For abbreviations and definitions see Figs. 3, 9, and 20; Table 1.) Based on percentages outlined in caption for Figure 20, fossil faunas from between lat 368 and 348N east of San Andreas fault and between 348 and 338N west of San Andreas fault lived in outer tropical paleoclimatic region, and all other fossil assemblages at all of other latitudes lived in warm temperate paleoclimatic region.

time slice because of the presence of Amusium lompocensis (Arnold) (23–13 Ma), Lyropecten crassicardo (Conrad) (18–8 Ma), and Pacipecten andersoni andersoni (Arnold) (23–13 Ma), and their overlapping age ranges. Kew (1924) applied the name Topanga Formation to rocks that are stratigraphically above the Vaqueros Formation and stratigraphically below the Modelo Formation. Yerkes et al. (1979) applied the name Topanga Group to Kew’s Topanga Formation and divided the group into, from oldest to youngest, the Topanga Formation, Conejo Volcanics, and Calabasas Formation. The Topanga Formation of the eastern Santa Monica Mountains and the Conejo Volcanics of Yerkes et al. (1979) are included in the 17–13 Ma time slice. The Calabasas Formation is assigned here to the 13– 8 Ma time slice because it is interbedded with, and stratigraphically above, the Conejo Volcanics, the age range of which is 16.0–13.5 Ma (Stadum, 1998). Blake (1991, Table 1) modified the Topanga Group defined by Yerkes et al. (1979) and placed the Topanga Formation, Conejo Volcanics, and Calabasas Formation of Yerkes et al. (1979) in a unit he referred to as the Modelo. However, Blake (1991, p. 146) noted that the Modelo Formation unconformably overlies the Topanga Group. Because of the presence of the unconformity, Blake’s (1991) stratigraphic assignments for the Topanga Formation and Conejo Volcanics are not followed herein.

Patinopecten haywardensis Lutz is present in the Sobrante Sandstone in Contra Costa County, and P. calaverasensis Hall, which is closely related to P. haywardensis, is present in the Sobrante Sandstone in Alameda County. Because Kleinpell (1938) assigned the Sobrante Sandstone to a Relizian Age, these two taxa are also assigned a Relizian Age (ca. 17.5–15 Ma). Hill (1979, Plate 2) assigned a Luisian Age to the Claremont Shale; however, K. McDougall (in Graymer et al., 1994) assigned a Mohnian Age to the formation. The Oursan Sandstone overlies the Claremont Shale. Kleinpell (1938) assigned a late Luisian Age to the shale. K. McDougall (in Graymer et al., 1994) assigned a Mohnian Age to the foraminifers from the Oursan Sandstone. Stratigraphically above the Oursan Sandstone are, in ascending order, the Tice Shale, Hambre Sandstone, Rodeo Shale, and Briones Formation. An age of 13 Ma is assigned to the Briones Formation (COSUNA, 1984). It is assumed here that the Oursan Sandstone is older than 13 Ma because it is stratigraphically well below the Briones Formation. The Oursan Sandstone contains, among other fossils, Anadara (Anadara) monteryana (Osmont) (age range of 23–13 Ma); Bruclarkia oregonensis (Conrad) (age range of 27–13 Ma); Dosinia cf. D. margaritana projecta Loel and Corey (age range of 23–13 Ma), Ficus (Ficus) modesta (Conrad) (age range of 27–13 Ma); Po-

Figure 24. This is same figure as Figure 23, except that fauna from Castaic Formation, which crops out between lat 358 and 348N west of San Andreas fault, is included in this analysis. Castaic Formation is included in 13–8 Ma time slice by some authors; however, it is included in 8–5 Ma time slice herein. If Castaic fauna is included in 13–8 Ma time slice, paleoclimate between lat 358 and 348N west of San Andreas fault remains same as shown in Figure 23, i.e., warm temperate, in contrast to outer tropical paleoclimate between these absolute latitudes east of San Andreas fault.

linices recluzianus andersoni (Clark) (age range of 27–13 Ma); and Priscofusus cf. P. hecoxi (Arnold) (age range of 17–13 Ma). Based on the work of Kleinpell (1938), the age assignment of the Briones Formation by COSUNA (1984), and the overlapping age ranges of the above molluscan taxa, the Oursan Sandstone is assigned to the 17–13 Ma time slice. The Tice Shale, Hambre Sandstone, and Rodeo Shale could be Mohnian in age; however, the three rock units are unlikely younger than 13 Ma because the age of the overlying Briones Formation is 13 Ma. 13–8 Ma time slice. The Sisquoc Formation is assigned to the 13–8 Ma time slice. In the Santa Maria basin the Sisquoc Formation discordantly overlies the Monterey Formation (Woodring and Bramlette, 1950, p. 26). There is also an unconformable relationship between the Monterey Formation and the overlying Miguelito and Edna members of the Pismo Formation to the north in the San Luis Obispo region. This relationship is well displayed along the coast between Avila and Pismo beaches in western San Luis Obispo County (Hall, 1973a), and regionally in the Pismo syncline south of San Luis Obispo (Hall, 1973a, 1973b). On the basis of stratigraphic and structural relationships, and molluscan fossils in the Sisquoc Formation and lower part of the Pismo Formation, the Pismo

and Sisquoc formations were considered by Hall (1973a) to be coeval. Keller (1992) considered this correlation to be “not tenable,” and she correlated the Miguelito Member of the Pismo Formation with the upper part of the Monterey Formation of the Santa Maria basin. Keller (1992) used diatom chronology to assign ages to these two units. However, the Edna and Miguelito members of the Pismo Formation interfinger and unconformably overlie, locally with an angular discordance of more than 308, the Monterey Formation in the Pismo syncline. The Miguelito Member of the Pismo Formation unconformably overlaps the Monterey Formation near the site of Keller’s (1992) research (i.e., 4–5 km southeast of Point Buchon, San Luis Obispo County). The unconformable relationship of the Edna and Miguelito Members of the Pismo Formation with the Monterey Formation precludes the inclusion of any part of the Edna or Miguelito members of the Pismo Formation in the Monterey Formation in the Pismo syncline. Fossils from the Isidro Formation (near lat 268N, Baja California Sur, Mexico) are not included herein. Smith (1984) assigned the Isidro Formation to an early Miocene age, but Squires and Demetrion (1993) assigned the formation a late medial Miocene age. Squires and Demetrion (1993) reported

Figure 25. Paleoclimate at various degrees of absolute latitudes west (WSA) and east (ESA) of San Andreas fault, 8–5 Ma. (For abbreviations and definitions see Figs. 3, 9, and 20; Table 1.) Based on percentages outlined in caption for Figure 20, fossil faunas from between lat 378 and 358N east of San Andreas fault, and between 388 and 368N west of San Andreas fault lived in temperate paleoclimatic region; those between 368 and 338N west of San Andreas fault lived in warm temperate paleoclimatic region; those between absolute latitudes of 288 and 278N lived in outer tropical paleoclimatic region; and those between 418 and 408N east of San Andreas fault lived in cool temperate paleoclimatic region. Inspection of bar graph suggests that fauna between lat 368 and 358N east of San Andreas fault (Panorama Hills) lived in warm temperate paleoclimatic region; however, analysis is based on only 11 taxa, therefore assignment of warm temperate paleoclimate between those latitudes is suspect.

Astrodapsis bajasurensis Squires and Demetrion from the Isidro Formation. Their new species also extends the southern geographic range of the genus Astrodapsis southward by 1100 km. Axelrod (1997, p. 1127) assigned an age of 7 Ma to what he referred to as the San Pablo flora, and he stated that the flora had a “warmth” of 14.4 8C, i.e., the continental temperature at the site of the flora was at least 14.4 8C for 194 days out of the year 7 m.y. ago. In this study the San Pablo Group includes, from oldest to youngest, the Briones, Cierbo, and Neroly Formations. These formations are assigned to the 13–8 Ma time slice. The youngest formation of these three, the Neroly, could be assigned to the 8–5 Ma time slice; however, because of the difficulty of regionally differentiating the Briones and Cierbo marine molluscan faunas from the Neroly marine molluscan fauna, the Neroly Formation is assigned to the 13–8 Ma time slice along with the fossil assemblages from the Briones and Cierbo Formations. Taxonomy and latitudinal ranges of taxa Faunal lists. The principal references used to compile the faunal lists (Appendix 1, Tables A7–A12) are listed in Appendix 3.

I used ;3254 taxa (mostly marine molluscan, several brachiopod and echinoid, and a few coral taxa) to infer the nearshore marine paleoclimatic conditions that existed during late Paleogene and Neogene time in western California. The taxonomy, geologic age or age range, and distribution of each of these taxa were determined. If a species of a fossil specimen is living today, the latitudinal endpoints of the present-day species are used in the analyses, even though there could have been physiological changes in the species during the geologic range of that species. If no living species exists for the fossil specimen, and if the genus of the fossil specimen is extant, the southernmost and northernmost latitudinal endpoints and range of ecologic information of the extant species in the genus are used in the analysis of the fossil and fossil assemblage. Of the ;3254 taxa recognized in this study, 282 taxa were considered in the analysis of the paleoclimate and paleogeography of the 27–23 Ma time slice, 345 taxa in the 23–17 Ma time slice, 515 taxa in the 17–13 Ma time slice, 631 taxa in the 13–8 Ma time slice, 578 taxa in the 8–5 Ma time slice, and 903 taxa in the 5–2.5 Ma time slice (Appendix 1, Tables A7–A12). The database for the lists of taxa is primarily from the published literature (Appendix 3). Additional data are from dissertations, theses, and written correspondence. These are noted in Appen-

Based on percentages outlined in caption for Figure 20, fossil faunas from between lat 398 and 358N east of San Andreas fault, and between 368 and 348N west of San Andreas fault lived in temperate paleoclimatic region; those between 348 and 278N west of San Andreas fault lived in warm temperate paleoclimatic region; and those between 428 and 408N east of San Andreas fault, and between 388 and 378N west of San Andreas fault lived in cool temperate paleoclimatic region.

The references utilized to arrive at the taxonomy used in this volume are listed in Appendix 4. References in the taxonomic studies cited in the list of references in Appendix 4 were also consulted but they are not listed. Doubtless there are taxonomic studies of individual taxa or taxonomic groups by specialists that have been overlooked. However, one of the goals of this study was to reduce, if not eliminate, synonyms, and to standardize the taxonomy of molluscan, brachiopod, and echinoid taxa from upper Paleogene and Neogene rocks of western California in order to complete the paleoclimatologic analyses of fossil assemblages from the six time slices; this goal has been achieved. Endpoints of geographic ranges and ecologic data of taxa. The endpoints of geographic ranges and the ecological data for taxa used in this study (Appendix 1, Tables A7–A12) are listed in Appendix 4.

Effective temperature The nearshore paleotemperature conditions in late Paleogene and Neogene paleoclimatic regions and the mean minimum sea-surface paleotemperatures at the northern latitudinal endpoints of nearshore marine taxa along the ancient coastline of California were probably not the same as those of today. The use of present-day mean minimum SSTs, which today coincide with the northern boundaries of molluscan provinces, to define late Paleogene and Neogene paleoclimatic regions has been shown to be flawed (Hall, 1964b, 1975a; Hall et al., 1974). In addition, the configuration of the ancient coastline of California was locally and regionally very different from the present-day coastline. Ancient peninsulas, straits, large embayments, and large island masses along western California represent some of the physiographic factors that influenced water-mass boundaries during the late Cenozoic. Other differences between the marine paleoclimate and the

Figure 27. Nearshore marine paleoclimate between lat 368 and 338N west of San Andreas fault (WSA) (degrees of absolute latitude). Sea level was lowered worldwide at 10.5, 5.5, and 2.5 Ma, and there was worldwide sea-level highstand between 17 and 14 Ma (Haq et al., 1987). (For abbreviations and definitions, see Figs. 1 and 7; Table 1.)

present-day marine climate along the west coast of California are as follows. (1) The large ancient marine embayments that were present from 27 to 7 Ma along the west coast of California were in very close proximity to an eastern mountainous region or a plateau (elevation of ;545 m) in eastern California and Nevada, and these areas were uplifted to 1400 m after late Neogene time, or after 7 Ma (Axelrod, 1997, p. 1127). (Wolfe and Schorn [1994] suggested higher altitudes above sea level for west-central Nevada at 16 Ma and collapse to present altitudes by 12 Ma; Wolfe et al. [1997] noted that the altitudes of western Nevada were 2900–3200 m above sea level between 16 and 15 Ma, and western Nevada had collapsed to 1000–1500 m by ca. 13 Ma. Small and Anderson [1995] suggested that 3 Ma marked the time of the initiation of the uplift of the Sierra Nevada to their present elevations.) (2) There was a relatively greater influx of fresh water into the protected marine basins during late Paleogene and Neogene time because of higher amounts of rainfall than today, based on paleobotanical evidence (Axelrod, 1985, 1991, 1992a, 1995). (3) Probable differences existed between the salinity of seawater in ancient marine basins and the salinity of seawater along the present-day coast of California because of the higher influx of rainwater flowing into the late Paleogene and early Neogene basins, and the isolation and shallowing of some of those ancient marine basins during medial and late Neogene time (Dodd and Stanton, 1975; Reid, 1995). (4) There were different water-circulation patterns in the past that influenced the ancient marine nearshore paleoclimates and regions of shallow and protected marine environments.

Present-day molluscan and paleomolluscan provinces The following part of this volume is devoted to the procedure for assigning temperature characteristics to molluscan taxa, faunal communities, and ultimately to marine nearshore paleoclimates. Present-day, shallow-water, marine molluscan provinces along the shelf of California are collections of communities; these communities are collections of populations. Populations commonly, and gradually, change with latitude. Communities intergrade with communities of adjoining molluscan provinces. However, the boundaries of most present-day molluscan provincial boundaries along the coast of California are easily recognized. Present-day molluscan provincial boundaries are drawn at the northern latitudinal endpoints of the geographic range of a relatively large number of species, or the boundaries are determined by analysis of molluscan distribution patterns that are computed by numerical analysis (e.g., Valentine, 1966). In both cases the same basic distributional data are used, i.e., the geographic endpoints of marine molluscan taxa. Along the present-day marine shelf of California and Baja California Sur, Mexico, faunal breaks in molluscan distribution patterns are present at latitudes 248–258, 288, 34.58, 378, and 488N, and at a me´lange of several more northerly latitudes that are more subjective boundaries. Brusca and Wallerstein (1979) differentiated zoogeographic provinces in the eastern Pacific Ocean based on the distribution of isopod crustaceans. Except for the provincial boundaries of

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines their Californian province and their Cortez province (preoccupied by the Surian province of Brusca and Wallerstein), their provincial boundaries are dramatically different from those of molluscan provincial boundaries, e.g., their Panamic province (tropical water mass) is between lat 158N and 38S. Four bivalve molluscan provinces were proposed by Bernard et al. (1991): (1) the Panamic province (tropical water mass) between lat 38S and 238N, (2) the Californian province (warm water mass) between 238 and 34.58N, (3) the Oregonian province between 34.58 and 668N, and (4) the Arctic province from 668N northward, e.g., to 728N. With this scheme it is not possible to differentiate temperate from cool temperate water mass boundaries. Bernard et al. (1991) recognized a transitional zone between lat 238 and 258N, but they placed the bivalve fauna in that ecotone within a Bivalvia Californian province. Crame (2000) recognized the following marine zoogeographic provinces based on bivalve mollusks: (1) the Panamic between lat 68S and 258N, the Californian between 258 and 358N, the Oregonian between 358 and 558N, the Aleutian between 558 and 608N, and the Arctic above 608N. In general, these are the same provinces that were delineated by earlier researchers. The following provinces and subprovinces are recognized herein. The northern boundary of the Panamic molluscan province (encompassing a tropical water mass) is near lat 248N. Keen (1971, p. 4) stated the following regarding the northern boundary of the Panamic province: “Natural limits of the Panamic province—Magdalena Bay (Bahıá Magdalena), Baja California Sur, and Punta Aguja, Peru.” Bahıá Magdalena is between lat 248 and 258N. Other researchers accept 238N, or Cabo San Lucas, as the northern boundary of the Panamic molluscan province (e.g., Bernard et al., 1991). Keen’s (1971) northern limit (248–258N) of the Panamic molluscan province is used herein. The southern boundary of the Surian molluscan province (outer tropical water mass) is at lat 258N and the northern boundary of the province is 288N; the Californian molluscan province is between 288 and 34.58N; the questionable Montereyan molluscan subprovince is between 34.58 and 378N; the Oregonian molluscan province (temperate water mass) is between 34.58N and either 488, 558, or 608N; and the Aleutian molluscan province (cool temperate water mass) is north of the Oregonian molluscan province with its northern boundary at 578, 608, or 628N, according to Zenkevitch (1963), Hall (1964b), Valentine (1966), and Kafanov (1991). Valentine (1966) included a historical review of the naming of molluscan provinces along the west coast of North America. The provincial names, in a sense the type localities of the present-day molluscan provinces, are derived from their geographic locations. Because the faunal compositions of molluscan provinces have not remained the same throughout geologic time, different paleomolluscan provincial names should be given to zoogeographic provinces for each segment of geologic time studied. For example, Valentine (1959, 1961) named

31

the following late Pleistocene molluscan provinces: the Magdalenan paleomolluscan province, which is geographically equivalent to his present-day Surian molluscan province; the Verdean paleomolluscan province (Valentine, 1966), which is generally geographically equivalent to the present-day Californian molluscan province; and the Cayucan paleomolluscan province, which is geographically equivalent at least in part to the Oregonian molluscan province. Hall (1960) named a present-day Magdalenan molluscan province for the coastal region along the southern tip of Baja California Sur, Mexico, which Valentine (1959, 1961, 1966) named as the present-day Surian molluscan province. Valentine (1966) correctly noted that Hall’s (1960) present-day Magdalenan molluscan province is preoccupied by his late Pleistocene Magdalenan molluscan province (Valentine, 1959). Thus, there should be different names for each of the paleomolluscan provinces that existed during the early to late Miocene, early to late Pliocene, and early and late Pleistocene time. There should also be separate paleomolluscan provinces for each and all of the shorter subdivisions of Paleogene and Neogene time. The naming of tens or even hundreds of different Paleogene and Neogene paleomolluscan provinces along the west coast of North America would be nomenclatorially and paleobiologically correct. However, a plethora of different paleomolluscan provinces is cumbersome, and in terms of making paleoclimatologic analyses the practice would have limited utility. In order to reduce a potentially large number of provincial paleomolluscan names, qualifying terms could be attached to the names of the presentday molluscan provinces. For example, a late Miocene–early Pliocene molluscan fauna (155 taxa) is present in rocks in Elsemere Canyon, which is between lat 348 and 338N in Los Angeles County, and west of the San Andreas fault. Many of the taxa in the Elsemere fauna have modern analogs that live in the present-day Californian molluscan province. For relative simplicity, the 155 taxa could be assigned to a late Miocene–early Pliocene paleo-Californian molluscan province, rather than to a possible Elsemerian province. However, if the practice of adding modifying time terms to present-day molluscan provincial names were to be adopted, there would be an implication that the paleomolluscan fauna is similar to, or the same as, the modern Californian molluscan fauna in the present-day molluscan province. Hall (1960) used this method of naming ancient provinces, and Addicott (1970b, 1970c) used a modification of the method. However, the practice is questioned because it does not acknowledge probable changes in biologic diversity and biogeographic and physical changes in the fauna and environment that have taken place in the past 5 m.y. Valentine (1966, p. 198) pointed out, “As climates have evolved, so have provincial regimes, and ancient forerunners of modern provinces have therefore not had similar thermal attributes.” Rosen (1984), Jablonski et al. (1985), Jablonski and Valentine (1990), and Roy et al. (1994, 1995, 1998) provided excellent discussions of present-day and ancient biogeographic regions and molluscan provinces. Several of these authors and

Jackson and Jonson (2001, p. 2401) also pointed out that the fossil record is biased and incomplete, the known geological lifetime of a taxon or a fossil species is imprecise, the paleogeographic ranges and the distribution of taxa are not known with precision, and fossils are unevenly distributed in time and space. On the basis of these arguments, the delineation of paleobiogeographic provinces, including paleomolluscan provincial boundaries, is difficult, and when achieved the delineation will be imprecise. However, the analysis of the geographic ranges of present-day molluscan species along the west coast of North America is relatively straightforward. The present-day California coastline is generally linear, and, except in the vicinity of the western Transverse Ranges, it is oriented north-south. Significant faunal changes in the distribution patterns of presentday molluscan faunas are present at the present-day latitudes noted herein, and present-day molluscan distributional patterns along the coast can be determined by using sample units of 18 of latitude (Valentine, 1966). However, the discrimination of present-day molluscan boundaries becomes more problematic in three regions: (1) at northern latitudes of western North America because of the influence of geography and floe ice; (2) along the west coast of Baja California Sur, Mexico, because taxa common at latitudes along that coast occupy protected bays along the exposed western coastline of Baja California Sur, whereas the unprotected western coastline is inhabited by taxa with northern faunal affinities; and (3) in the present-day Gulf of California because of different oceanographic conditions in the gulf than those present along much of the west coast of North America. Unlike the delineation of present-day molluscan provinces, the presence and distribution of fossil taxa are generally insufficient in number and paleogeographic extent to use the endpoints of their geographic ranges to identify paleomolluscan provinces. In addition, as pointed out by Russell and Lindberg (1988, p. 325), “ . . . geographically short-ranging species are less likely to be represented in the fossil record than geographically long-ranging species because of their local rarity.” In addition, the use of cluster analyses (e.g., Valentine, 1966; Valentine and Peddicord, 1967) to determine paleogeographic range patterns of fossil species and provincial paleomolluscan faunal boundaries older than the Pleistocene is of limited use when analyzing Neogene faunal assemblages. The delineation of late Paleogene and Neogene paleomolluscan provinces is not straightforward because (1) there is a local paucity of fossil material and the presence of fossil mollusks is regionally limited; (2) the coastline of much of California was embayed during late Paleogene and Neogene time (Plates 2–8); (3) the region west of the San Andreas fault was tens to hundreds of kilometers to the south of where it is today (Atwater, 1970, 1989; Atwater and Molnar, 1973; Dickinson, 1996, 1997; Dickinson and Wernicke, 1997; Atwater and Stock, 1998); and (4) the present-day east-west–oriented western Transverse Ranges were not only well south of the absolute latitudes of where they are today, but they were oriented nearly north-south before they

were rotated as much as 1308 in a clockwise direction since 17 Ma (Jones et al., 1976; Hamilton, 1978; Crouch, 1979; Kamerling and Luyendyk, 1979, 1985; Luyendyk et al., 1980, 1988; Hornafius, 1984, 1985; Hornafius et al., 1986; Luyendyk and Hornafius, 1987; Crouch and Suppe, 1993; Nicholson et al., 1994; Fritsche, 1997, 1998; Ingersoll and Rumelhart, 1997, 1999; Rumelhart and Ingersoll, 1997). Taking into consideration these three factors, there were many protected bays along the open parts of the west coast of California during Neogene time, which were analogous to and larger than the modern bays such as San Francisco Bay, California (lat 388N), Bahıá Magdalena (258N), Laguna San Ignacio (278N), and Laguna Ojo de Liebre (Scammon’s Lagoon) in Bahıá de Sebastiań Vizcaıńo, Mexico (288N). Monterey Bay, California (present-day latitude of ;378N), was near the present-day latitude of Lancaster, Los Angeles County, California (;358N), 27–17 Ma; Santa Barbara, California (present-day latitude 34.58N), was near the absolute latitude of 32.58N during the same time period; the Santa Barbara coastline was oriented north-south; and a gulf similar in width (120 km) to the present-day northern Gulf of California (width of 200 km in the north) was present between Santa Barbara and San Diego from 27 to 17 Ma. Recognizing the imprecision and shortcomings of inferring late Paleogene and Neogene marine paleoclimates in western California, particularly in contrast to the detailed analyses of Pleistocene and present-day mollusks presented by others, a paleoclimatologic study of late Paleogene and Neogene time of California was carried out using the present-day distribution of molluscan taxa to infer SST for the following reasons. (1) There is no known detailed analysis of marine late Paleogene and Neogene paleoclimatic regions that considers the paleogeographic reconstruction of all of California for the 25 m.y. period from 27 to 2.5 Ma. (2) The number of isotopic-temperature analyses is limited. (3) There are uncertainties about some paleotemperatures that have been inferred using isotopic analyses of nearshore fossil organisms because of the influx of fresh water into marine basins and a lack of paleosalinity data for those basins. Climatic regions Present-day continental climatic regions of the world were defined by Ko¨ppen (1894), who based his classification of climatic regions on the distribution of present-day global patterns of vegetation, e.g., the distribution of rainforests; savannas or grasslands containing scattered trees and drought-resistant undergrowth; steppe or xeric vegetation; desert vegetation; and taiga or coniferous forests, beginning where the tundra (dwarf herbs) ends, dominated by spruce (Picea) and firs (Abies). Ko¨ppen’s definitions of climatic regions were later revised and modified (see Akin, 1991, p. 50–81 for a discussion of the modifications). Climatological characteristics of, e.g., rainfall, minimal temperatures, and seasonal precipitation, are applied to the biogeographical regions delineated by Ko¨ppen (1894)

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines and others, and some of these characteristics are used in turn to thermally define climatic regions, e.g., (1) tropical forest climatic region, coolest month above 18.0 8C; (2) tropical savanna climatic region, coolest month above 18.0 8C but seasonal rainfall; and (3) subtropical humid climatic region, warmest month above 10.0 8C, coldest month above 0 8C and summer rain. General climatological terms also have been applied to these continental climatic regions based on plant biogeography, e.g., tropical, subtropical, warm temperate, and temperate zones. Present-day nearshore zoogeographic provinces along the Pacific coast of North America were delineated by Dana (1848, 1853), Forbes (1853, 1856), Woodward (1856), Fischer (1887), Dall (1921), Bartsch (1912), Smith (1919), Schenck and Keen (1936), Newell (1948), Hall (1964b), and Valentine (1966). Dana (1853) applied relative temperature terms to zoogeographic provinces and in doing so defined marine climatic regions, e.g., torrid, warm temperate, and temperate; however, his marine climatic zones were not defined in terms of temperature. Davies (1934) outlined zoogeographic provinces, e.g., Panamic, Californian, and Aleutian, but did not assign thermal characteristics to the provinces. Vaughn (1940) applied temperature limits to climatic regions that were defined by biogeographic zones, regions or provinces, e.g., 25.0 8C and higher seawater temperatures for the tropical biogeographic zone, and 15.0 8C and higher water temperatures for the subtropical biogeographic zone or region. Hall (1964b) delineated present-day marine climatic regions based on the distribution of living and fossil shallowmarine mollusks. Climatic regions were defined by duration of warmth. Because the thermal terms subtropical, warm temperate, and cool temperate are imprecise, assigning a duration of warmth to climatic regions attempted to provide some notion as to the nearshore SST in the climate regions. The use of mean minimum SSTs at provincial boundaries to define present-day climatic regional water-mass boundaries does not correspond in every case with faunal discontinuities associated with present-day marine zoogeographic data (Hall, 1964b). Because there are durations of warmth of SSTs at molluscan provincial boundaries in the eastern Pacific Ocean that are remarkably similar to thermal boundaries at marine provincial boundaries in the eastern and western Atlantic Ocean, the western Pacific Ocean, and the Gulf of California, duration of warmth was used to define present-day marine climatic regions (Hall, 1964b, p. 232). Hall’s (1964b) definitions of present-day marine climatic regions, not provinces, were not intended to imply that all mollusks living within a particular molluscan province are controlled exclusively by a single thermal attribute such as duration of warmth or any other single thermal attribute. Provincial patterns are controlled by thermal regimes, not single temperature conditions as discussed by Valentine (1966). Valentine (1966, p. 209) also suggested a caution: “To specify boundary temperatures between two provinces involves a limitation when referring to the past; the specification is valid only since the climatic regime was about the same as it is at present.”

33

However, his statement implies that if temperatures are assigned to present-day molluscan provincial boundaries, those provincial-boundary temperatures will only be valid for presentday and Pleistocene provincial-boundary temperatures. If the inference drawn from this statement is correct, the statement may have been premature or too pessimistic regarding the use of present-day provincial-boundary temperatures to interpret climatic trends older than the Pleistocene. For example, Addicott (1970b, 1970c) equated the present-day molluscan provinces, Panamic, Surian, and Californian (Valentine, 1966), to the tropical, subtropical, and warm temperate marine climatic regions. He also projected the Panamic, Surian, and Californian provincial or climatic boundaries through a duration of more than 30 m.y. (Oligocene to Pliocene). Durham (1950a) used marine taxa restricted to present-day biogeographic provinces to plot the latitudinal positions of the inferred 25.0, 20.0, 18.0, 13.0, and 12.0 8C paleoisotherms, at least one of these marking a present-day provincial boundary, for a 60 m.y. period of time. Durham’s (1950a) study indicated that ocean temperatures have cooled during the past 60 m.y. Durham’s (1950a) thesis is supported by global isotopic studies (Savin et al., 1975; Shackleton and Kennett, 1975; Kennett, 1977, 1980, 1986a, 1986b; DePaolo and Ingram, 1985; Vincent and Berger, 1985; Vincent and Killingley, 1985; Capo and DePaolo, 1986; DePaolo, 1986; Miller et al., 1987; Muhs and Kyser, 1987; Woodruff and Savin, 1989, 1991; Compton et al., 1990; DePaolo and Finger, 1991; Wright et al., 1992; Flower and Kennett, 1993a, 1993b; Schoell et al., 1994). Jablonski et al. (1985, p. 79) implied support for the use of present-day provincial-boundary temperatures to interpret past climatic trends older than the Pleistocene when they stated the following: The provincialization of the Cenozoic biota provides a potential natural laboratory for the role of biogeographic change in the origin and persistence of higher taxa. Both biogeographic evidence (see Durham 1950; Addicott 1970) and oxygen isotopic evidence (see Douglas and Woodruff 1981) suggest that ocean temperatures in high latitudes have cooled significantly during the Neogene (perhaps by as much as 10 8C), steepening the latitudinal thermal gradient and giving rise to chains of climatically based latitudinal provinces along north-southtrending continental shelves (Valentine 1967, 1973a).

Jablonski et al. (1985, p. 76) also stated the following regarding determinants of the geographic ranges of species: Provincial boundaries occur at barriers that limit the ranges of many species, and recent advances in marine physiology provide a new understanding of the evolutionary basis of species range endpoints. It has long been clear that temperature is the major determinant of geographic range of poikilothermous species in the sea.

A challenge presented to the paleobiologist is how to use temperature to define marine present-day and marine paleoclimatic regions. Without definitions of present-day marine climatic regions, how can marine paleoclimatic regions be reasonably defined, and how can present-day climatic and

paleoclimatic regions be compared? What is meant by the terms “tropical,” “warm,” and “cool” relative to present and past marine climates; and by “warming” and “cooling” relative to changes in ancient climates? Continental climatic regions defined by temperature “Warmth” has been used to define continental climatic regions (Bailey, 1960). The underlying assumption regarding the importance to life of warmth is “that the flow and ebb of life are related systematically with the thermal environment” (Bailey, 1960, p. 2). Other conditions important to maintaining life are the thermal control of physiological processes and the reproductive cycle, the length of the day, seasonal changes in temperature, limiting temperatures for existence, and in the case of marine organisms, temperatures and light related to food production, and postreproductive and prereproductive cycles. Bailey (1960) recognized both the inadequacies of defining continental climatic regions by warmth and the existence of other factors that control the distribution of life. These inadequacies are equally applicable when defining marine climatic regions. Bailey (1960, p. 2) stated, “The parallelism of many seasonal changes to those of temperature thereby imparts an apparent reality to thermal control [of organisms] beyond its true value. As a result approximations are achieved that must admit of many contradictions in detail, contradictions caused by lack of coordination of actual determinants with temperature trends” (my brackets). Having acknowledged the inadequacies, Bailey (1960) developed a planetary model that adjusts warmth and length of summer to define climatic regions. Warmth is defined as a single temperature value that stands for a complete temperature regime, or population and range of temperature values; it has been termed effective temperature (ET) (Bailey, 1960, 1964, 1966; Axelrod, 1967b, 1980; Axelrod and Bailey, 1969), or its synonym, warmth (W) (Axelrod, 1985, 1991, 1995, 1997). Fundamental to the process of determining ET, there are two defining limits to the classification of climates based on present-day plant distribution or plant geography. (1) A thermal limit to tropical continental climates is given as 18.0 8C for the coldest month of the year, and (2) a limit to polar climate is given as 10.0 8C for the warmest month of the year. Tropical climates can be viewed as ones that lack a winter, whereas the polar climates essentially lack a summer. Axelrod and Bailey (1969, p. 175–176) stated “The agreement of the 50 8F (10 8C) mean for the warmest month of the year with the polar tree limit has long been accepted”; “The border of tropical vegetation can not be matched as well by any single isotherm owing to the intrusion of effects related to moisture deficiency”; and “A mean temperature of 64.4 8F (18.0 8C) for the coldest month of the year has been adopted as the thermal limit of tropical life zone.” The difference between the means of the warmest month and the coldest month defines the mean or average annual range of temperature (referred to as A or AR by Bailey, 1960, and

Axelrod and Bailey, 1969). This range, coupled with mean annual temperature (T), “provides a basis for estimating (1) the means for all months; (2) the extreme range (the difference between the highest and lowest temperature record); and (3) the frequency of a stipulated temperature class, notably the percentage of the hours of the year with subfreezing temperature” (Axelrod and Bailey, 1969, p. 169). The mean annual T alone has no climatic significance in terrestrial environments (Axelrod, 1992b), and it is assumed here that it has no significance in defining nearshore marine climates. Roy et al. (1998), however, suggested that average annual temperature is important. Roy et al. (1998, p. 3699), in discussing shared diversity patterns among gastropods living in the eastern Pacific and western Atlantic Oceans, noted that diversity values in both oceans can be explained by “solar energy input, as represented by average sea surface temperature.” Determining average annual, sea-surface paleotemperatures based on the distribution and presence of fossil marine mollusks is not feasible; using isotope geochemistry to determine average annual SSTs over many degrees of latitude and among widely distributed fossil assemblages is not currently practical. The equation for expressing warmth (ET) is: ET 4 (8 T ` 14 AR)/(AR ` 8) 4 (18 WM 1 10 CM)/(WM 1 CM ` 8),

(1)

where temperatures are in 8C; T and AR refer to mean or average annual temperature and range of temperature, respectively; and WM and CM refer to the mean or average temperatures of the warmest and coldest months of the year, respectively. The coefficient 8 is the difference between the coolest mean temperature for the tropical life zone (taken as 18 8C) and the warmest polar climate (taken as 10 8C). The coefficient 14 AR is the average temperature range (14 8C for 183 days) during the annual march of temperature (Bailey, 1960, p. 11; Axelrod and Bailey, 1969, p. 174). Effective temperature is based on the assumptions that polar climate essentially lacks a summer, tropical climate lacks a winter, and there is an annual march of temperature that approximates a sine wave. Quantification of warmth (ET) furnishes both a single temperature and the duration of the period in which temperatures are warmer than the ET. There is a trigonometric relationship between ET and the sine wave representing the annual temperature cycle. The equation for determining the duration in days of the year when the mean temperatures are warmer than the effective temperature is: Td 4 182.6 ` 2.03a.

(2)

Td is the duration in days and a is an angle determined by the relations: sine a (in degrees) 4 (ET 1 14)/4 (when ET is in 8C) (Bailey, 1960, p. 4; Axelrod and Bailey, 1969, p. 174). Applying these formulas, days of summer season (Td),

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines when the mean SSTs are warmer than the ET, and ET, reflecting a duration of warmth, are shown in Table 2. The scale of effective temperatures proposed by Bailey (1960) measures warmth by defining a sliding scale specifying temperatures at the beginning and end of a warm period, and the duration of that period. Based on the distribution of warmth over the world, excluding Antarctica, Bailey (1960, p. 8) defined five present-day continental climatic regions of the world delineated by effective temperatures between 10.0 8C (Td 4 0.0) and 18.0 8C (Td 4 365.1): (1) very cool, ET between 10.0 and 11.6 8C; (2) cool, ET between 11.6 and 13.4 8C; (3) mild, ET between 13.4 and 15.5 8C; (4) warm, ET between 15.5 and 18.0 8C; and (5) very warm, ET between 18.0 and 20.8 8C. Marine climatic regions defined by temperature Briggs (1995, p. 209 and Fig. 55) delineated the northern boundary (lat ;248N) of a northeastern Pacific Ocean tropical climatic zone, or region, by the marine 20.0 8C minimum isotherm. He depicted a warm temperate marine climatic region with winter SSTs of 20.0–12.0 8C (northern boundary apparently at ;408N) and a cold temperate region. Minimum SSTs between 12.0 and 2.0 8C characterize the latter zone; Briggs (1995, Fig. 55) depicted no northern boundary of this region. Briggs (1995, Figs. 88 and 89) also delineated open-ocean climatic zones or regions based on the distribution of microorganisms. Both sets of climatic regions delineated by Briggs (1995) are too general in terms of thermal and geographic limits to be useful in considering the biogeography of the present-day TABLE 2.

eastern Pacific Ocean molluscan fauna and for assigning paleoclimatic regions to late Paleogene and Neogene nearshore marine regions of California. In order to define nearshore marine climatic regions in greater detail, the general planetary climate model and the mathematical treatment of warm month–cold month relations described by Bailey (1960, 1964, 1966) are used to determine the ET at the boundaries of present-day molluscan provinces, which in turn delineate marine climatic regions. Recognizing the shortcomings of defining continental climatic regions by warmth, and in this study marine climatic regions, the planetary model that adjusts warmth and length of summer to define climatic regions developed by Bailey (1960) for continental climates is nevertheless used to delineate marine climatic regions. Warmth (ET or W) is defined as a single temperature value that stands for a complete population or range of temperature values—a temperature regime. The northern boundaries of the present-day molluscan provinces are (1) Panamic, lat ;248N; (2) Surian, ;288N; (3) Californian, 34.58N; (4) Oregonian, either at 488 or at 558N; and (5) Aleutian, 578, 608, or 628N (Zenkevitch, 1963; Hall, 1964b; Valentine, 1966; Jablonski and Valentine, 1990; Kafanov, 1991). These zoogeographic regions are considered herein in the same way that global patterns of vegetation of the world have been used to define present-day continental climatic regions (Ko¨ppen, 1894; Bailey, 1960). The five eastern Pacific molluscan provinces listed here are considered here to delineate water masses or oceanic regions in the nearshore environments of the eastern Pacific Ocean. However, for convenience and for the purposes of outlining marine nearshore paleoclimatic regions of California, the present-day coastal oceanic water masses are referred to as climatic regions. Molluscan provinces in the western Pacific, eastern Atlantic, and western Atlantic Oceans can also be used to delimit present-day marine climatic regions (Hall, 1964b). The northernmost boundary of the Aleutian molluscan province is considered in this analysis to be near lat 628N (Zenkevitch, 1963), a latitude where the SST is 10.0 8C, or it is ;10 8C during the warmest month of the year. The northern boundary of the Panamic molluscan province is between 248 and 258N (as defined by Keen, 1971, p. 4), and the SST during the coldest month of the year in that latitudinal range is between 17.78 and 19.45 8C; i.e., it can be ,20 8C. As with the determination of effective temperatures on the continents (Bailey, 1960), two thermal limits (;18.0 and ;10.0 8C) in the classification of marine climatic regions based on present-day molluscan distribution are fundamental to determining the ET in marine shelf environments. Bailey (1960) took the worldwide annual range of continental temperature to be between 0 and 30 8C in order to estimate the world’s average annual range of temperature (AR or A) and average annual temperature (T). The same approximation for the annual range of temperature is taken here for the annual range of marine temperature. On the basis of available present-day SSTs, i.e., ;11.67 8C for the coldest marine temperature in the Arctic region and 29.56 8C for the warmest marine temperature in the

eastern Pacific Ocean, the annual range of SST is not greatly different from the continental range. An average AR and an average annual T for marine regions can be calculated using temperatures ,0 8C and .30 8C. However, given that the effective temperatures calculated throughout this study are approximations in order to arrive at some notion regarding the paleo-SSTs for paleomarine coastal oceanic waters rather than the less than meaningful terms such as “temperate” or “tropical,” and for purposes of approximating the duration of warmth of paleocoastal waters, the worldwide annual range of SSTs is taken to be 0–30 8C. A thermal boundary for tropical marine climatic regions is taken to be ;18.0 8C for the coldest month of the year because the winter minimum temperature at the northern boundary of the Panamic molluscan province is between 17.78 and 19.45 8C. The minimum SST to which reef-building or zooxanthellate corals are normally exposed is 18 8C (Veron, 1995). The southern boundary of the near polar marine climatic region in the northeastern Pacific Ocean is taken as between 9.44 and 10.04 8C during the warmest month of the year because these temperatures represent the approximate SSTs during the warmest month of the year at the northern boundary of the Aleutian molluscan province. The mathematics, trigonometry, and statistics that are used to determine the ET and the duration of warmth (Td) of marine climatic regions, regardless of whether SSTs or land temperatures are used, were given by Bailey (1960, 1964, 1966), and in part by Axelrod and Bailey (1969). Axelrod and Bailey (1969) also depicted the concept of ET in nomographic form. As shown in the formulas used to calculate ET, the mean annual range of temperature (A or AR) is defined by the difference in the means of the warmest and coldest monthly temperatures. The mean warmest and coldest month SSTs can be obtained for the present-day eastern Pacific Ocean from a variety of sources, including the U.S. Navy, Chief of Naval Operations (1956– 1958), Norpac Atlas (1960), Robinson (1973), and Levitus and Boyer (1994). The SST data used in this study are from the U.S. Navy, Chief of Naval Operations (1956–1958). A longterm mean annual SST (T) in the nearshore eastern Pacific Ocean between lat 338 and 488N can be obtained from Scripps Institution of Oceanography (1995). With these data, the ET for each line of latitude and for each present-day molluscan provincial boundary along the coast of California can be calculated. Determining the mean annual sea-surface paleotemperature (T) in the ancient Pacific Ocean and along the west coast of California from fossil molluscan distribution patterns is not feasible using temperatures at endpoints of geographic ranges of molluscan taxa, although Axelrod and Bailey (1969) estimated mean annual paleotemperatures for Paleogene and Neogene continental floras. Effective temperature at present-day molluscan provincial boundaries can also be calculated using the formula: ET 4 (18 WM) 1 (10 CM)/(WM 1 CM ` 8) (WM and CM being the mean or average temperatures of the warmest and coldest months of the year at the latitude in ques-

tion) (Bailey, 1960). The present-day effective temperatures at many degrees of latitude from high polar latitudes to the northern boundary of the Panamic molluscan province and ranges of effective temperature are shown in Table 3. These ranges reflect the differences in coldest month and warmest month SSTs based on different references for the data and other possible SSTs related to the interpolation between isotherms and variables involving air temperatures. The ET at each of these latitudes is calculated by using the average SST data for that latitude and the formula used to calculate ET (Table 3). The SST fluctuates due to El Ninõ and La Ninã oscillations (see Hughen et al., 1999), and there are some distinct differences between the warmest and coldest month SSTs recorded, e.g., by the Scripps Institution of Oceanography at different latitudes along the west coast of the United States in 1994 and the SSTs in the U.S. Navy, Chief of Naval Operations (1956– 1958) atlases. However, the differences between the values of ET calculated using different SST data sources are relatively insignificant, e.g., ET values of 15.14, 15.51, and 15.61 8C at lat 348N. The ET at lat 348N is significantly different from that at 358N using the same sources of SST data, e.g., 13.5, 13.5, and 13.53 8C. The northern boundary of molluscan provincial boundaries in the eastern Pacific Ocean and the boundaries of the marine climatic regions are also indicated in Table 3. Five marine water masses or climatic regions of the eastern Pacific Ocean are delineated between effective temperatures of 10.0 8C (Td 4 0.0) and 18.0 8C (Td 4 365): (1) cool temperate, between ET of 9.77 or 10.31 and 11.81 or 12.05 8C; (2) temperate, between ET of 12.05 or 12.64 and 13.53 8C (the ET of 13.94 8C at Monterey Bay probably does not represent the open coastal ET at lat 378N); (3) warm temperate between ET of 14.79 or 15.57 8C and 16.78 or 17.10 8C; (4) outer tropical, between ET of 17.16 or 17.48 and 17.88 or 18.20 8C; and (5) inner tropical, between ET 18.49 or 18.85 and 26.11 or 26.63 8C (Tables 3 and 4). When determining the effective temperature at continental latitudes, the northern temperature limit of the tropical life zone is taken as a mean of 18 8C (see Bailey, 1960; Axelrod and Bailey, 1969). The northern limit of the Panamic molluscan province is considered here to be between lat 24 and 258N (Keen, 1971). The mean SST during the coldest month of the year near these latitudes is between 17.88 and 19.45 8C. The effective temperatures in Table 3 were approximated using 18 8C. When approximating the effective temperature at marine coastal latitudes, the northern limit of the Aleutian molluscan provinces is used, which is between lat 62 and 608N. The mean SST during the warmest month of the year at these latitudes is between 10.0 and 10.80 8C: 10 8C was used to approximate the effective temperatures in Table 3. When determining the effective temperature at continental latitudes, the northern limit of the polar climate coincides with the northern polar tree limit. The mean temperature during the warmest month of the year at the polar tree limit is 10 8C. Other possible SST limits were used to approximate effective temperature at marine climatic

Owing to geologic or tectonic complexities in western California, widely scattered late Paleogene and Neogene fossil localities, and locally small late Paleogene and Neogene fossil faunal assemblages, it is difficult to develop distribution patterns of fossil mollusks in ways similar to those used for present-day mollusks living in the eastern Pacific Ocean (see Durham, 1967). The uncertainties of the true latitudinal endpoints of the fossil taxa result in approximations when assigning boundaries to paleomolluscan provinces. Recognizing the difficulties in delimiting late Paleogene and Neogene paleomolluscan provinces, Addicott (1969a, 1970b, 1970c, p. 289) analyzed “the warm-water element of middle-latitude molluscan faunas” in order to evaluate paleoclimatic change, and developed a series of profiles for a 30–40 m.y. duration of time in which cumulative percentages of warm water faunal elements were plotted against latitude. The profiles were based on fossil shallow-water molluscan genera that have present-day descendants living in the eastern Pacific Ocean. The genera of fossils Addicott analyzed were assigned to present-day molluscan provinces (i.e., Panamic, Surian, and Californian) in which their northernmost present-day geographic location is recorded. His zoogeographic profiles delineated the Californian, Surian, and Panamic molluscan and paleomolluscan provinces through a 40 m.y. period

boundaries in order to depict systematic latitudinal differences that persist in effective temperature from north to south. Different temperature limits also change the coefficients in the formula: ET 4 (18 WM 1 10 CM)/(WM 1 CM ` 8). The coefficients in the formula are 18, the coldest temperature at the northern geographic endpoint of the Panamic province; 10, the warmest temperature at the southern limit of the Aleutian molluscan province; and 8, the difference between these two coefficients (Bailey, 1960; Axelrod and Bailey, 1969) (using these coefficients, examples of marine ET values are given in Table 4, columns a and b). In Table 4, columns c–j, effective temperatures for nearshore marine water masses were calculated using other coefficients in order to depict possible ranges of ET at various latitudes. A visual comparison can be made between the mean values of effective temperatures and standard deviations using different coefficients in Table 4 from those used in Table 3 and for this study. The mean values of ET in Table 4 are somewhat higher than those used in Table 3; therefore, the approximations of ET values for this study could be considered to be systematically too low at the latitudes shown in Table 3. An indication of the number of molluscan species, the number of endemic species, and the percentage of endemic species in each of these present-day molluscan provinces used to define nearshore climatic regions is provided in Table 5 in order to illustrate the latitudinal faunal diversity gradient associated with the climatic regions and the latitudinal effective temperature gradient illustrated in Tables 3 and 4.

It is inferred that Addicott (1970c, p. 292) considered that the present-day Californian, Surian, and Panamic molluscan provincial names used in his analysis delineated warm temperate, subtropical, and tropical climatic regions or water masses, respectively; and his profiles of the molluscan provinces represent paleoclimatic changes through time. Using Addicott’s (1969a, 1970b, 1970c) concept for inferring paleoclimatic changes along the west coast of North America as a basis for assigning marine paleoclimatic regions to late Paleogene and Neogene marine basins of California, effective temperatures are assigned to late Paleogene and Neogene marine molluscan taxa from southern Oregon, California, and Alta Mexico. These temperatures reflect the warmth of the marine nearshore climate at the northernmost present-day endpoint of the extant taxa (Appendix 1, Tables A7–A12). For example, Argopecten ventricosus ventricosus (Sowerby) [4 A. circularis circularis (Sowerby) in literature] from upper Miocene to lower Pliocene rocks (lat 348–338N) west of the San Andreas fault is assigned an ET of 16.45 8C (Appendix 1, Table A11). This temperature was calculated from winter minimum and summer maximum temperatures at the northern endpoint of the range (lat 308N) of the living A. ventricosus ventricosus (Sowerby) (Tables 3 and 4; Appendix 1, Tables A11, A14, and A15 [and see Appendix 5]). The ET was calculated using the formula: ET 4 (18 WM 1 10 CM)/(WM 1 CM ` 8) (Bailey, 1960). The taxon is thermally characterized by a single temperature value (ET) reflecting the beginning and end of a warm period, and the duration of that period at the northern endpoint of its geographic range rather than by a winter minimum temperature, as used by Durham (1950a) and apparently by Addicott (1970b, 1970c). Because water-mass boundaries are more effective barriers for southern species migrating north in response to changing climatic conditions than for northern species moving south (Roy et al., 1995), an ET is assigned to a taxon based on temperatures at the northern endpoint of the range of the taxon. The assumption is made here that there is an actual thermal control of physiologic processes of many molluscan taxon (e.g., as discussed by Jablonski et al., 1985). Temperature is assumed to be the major determinant of geographic range of nearshore molluscan taxa (Jablonski et al., 1985), and if the boundaries of paleoclimatic regions are to be determined, there is a need to infer temperatures that limit the distribution of nearshore fossil mollusks based on present-day distributional data (Valentine and Meade, 1961), and to categorize the fossil taxa thermally. The assignment of an ET to Argopecten ventricosus ventricosus (Sowerby) and effective temperatures to other molluscan taxa based on the SSTs at the northern endpoints of the geographic ranges of the present-day descendants of the fossil taxa only allows for approximations or possibilities regarding thermal tolerances of the taxon, or other taxa. The reason for

this is the lack of knowledge of the actual determinants and thermal tolerances that control the distribution of mollusks. In addition, the thermal tolerances of a taxon (for larval, veliger, and adult stages) may have changed over geologic time. As northern latitudinal regions cooled during late Paleogene time and the Neogene Period, the tropical region became warmer and greater species diversity ensued (Valentine, 1967; Axelrod, 1992b). Some late Paleogene and Neogene stenothermic species could have adapted to cooling and warming in marine climatic regions. New taxa could have evolved in the developing cooler regions and in subregions of the warming tropics. Some species and genera could have survived in some climatic regions because there were not extremes in SSTs in that region. Nevertheless, mean annual temperatures and mean annual ranges of temperatures (differences between warmest and coldest temperatures at the same latitude), as a working hypothesis, delineate or approximate the thermal field that circumscribes the distribution of present-day and fossil molluscan taxa, communities, and provinces. Percentage of fossil taxa with a particular effective temperature The effective temperatures for late Paleogene and Neogene taxa within each time slice and within a degree of absolute latitude both east and west of the San Andreas fault were tabulated in order to depict the number of taxa and the percentage of those taxa with a particular ET and range of effective temperatures (Figs. 3–8). The tabulation was facilitated by the ET, and a catalog number was assigned to each valid taxon in each time slice (numbers 1–999 to taxa in the 5–2.5 Ma time slice; 1000–1999 to taxa in the 8–5 Ma time slice; 2000–2999 to taxa in the 13–8 Ma time slice; 3000–3999 to taxa in the 17–13 Ma time slice; 4000–4999 to taxa in the 23–17 Ma time slice; and 5000–5999 to taxa in the 27–23 Ma time slice) (Appendix 1, Tables A7–A12). Only one catalog number was assigned to a taxon in each time slice (synonyms were not assigned a number). The same taxon can be in more than one time slice; therefore it can have different catalog numbers in different time slices. Only one catalog number was entered for each valid taxon in 18 of latitude for each of the time slices, although the same numbered taxon can appear in more than one latitudinal group (Appendix 1, Tables A7–A12). Valid taxa with an ET of ,;10.0 8C (Appendix 1, Tables A7–A12) are not included in the tabulation (Figs. 3–8) because it is assumed that warmth at the northern endpoint of the range of those taxa with an ET of ,10.0 8C is not a factor limiting the northern latitudinal distribution of taxa that are living today in the Arctic (cold climatic region) and north of the Aleutian molluscan province (cold temperate climatic region). This assumption for some taxa living in the Arctic climatic region may not be valid. Ranges of ET of the fossil taxa are grouped into packages of effective temperatures that most closely approximate the ranges of ET of present-day nearshore marine climatic regions

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines in the eastern Pacific Ocean: cold temperate paleoclimatic region (ET 10.0–12.0 8C), temperate climatic region (ET 12.06– 15.05 8C), warm temperate climatic region (ET 15.51–16.78 8C), outer tropical climatic region (ET 16.98–17.90 8C), and inner tropical climatic region (ET 18.44–23.96 8C) (Figs. 3–8). Present-day mean values of ET water masses are: cool temperate, 11.0 8C; temperate, 13.51 8C; warm temperate, 16.07 8C; and outer tropical, 18.19 8C. The ET values are, in general, substantially higher than the mean values of ET of paleoclimatic regions: cool temperate, 11.46 8C; temperate, 12.51 8C; warm temperate, 13.44 8C; and outer tropical, 14.75 8C. However, other characteristics of the fossil faunas clearly differentiate the climatic regions and suggest correlations with modern-day nearshore climatic regions (Table 1; Figs. 3–9). PALEOSHORELINE MAPS AND PALEOCLIMATIC REGIONS Palinspastic maps of western California were drawn for each of the six time slices by back slipping fault blocks along faults for which there are previously determined amounts of right and left slip (Plate 1; Appendix 1, Table A16). Appendix 6A lists the references used to construct the overall base maps. Of greatest importance to the palinspastic reconstructions is the restoration of strike slip in western California. The reason for the importance is that it was necessary to restore faunal assemblages to their paleolatitudes. To not make the restoration, i.e., leaving faunal assemblages at absolute latitudes, does not help the reader understand in a depictive way where the mollusks and other marine organisms were living. Western Nevada and eastern California have not been palinspastically restored. Faults and geographic features in western Nevada and eastern California are largely absent from the palinspastic maps (Plates 1–8), indicating that this area has not been considered in the reconstructions. The state boundaries are provided only for reference. The pre–Basin and Range province was not palinspastically reconstructed. Dickinson and Wernicke (1997, p. 665) concluded the following: Summation of (1) 315 5 10 km of San Andreas offset in central California, (2) 208 5 22 km of additional transrotational shear (as imparted by rotation of the western Transverse Ranges but exclusive of 58 5 18 km of transrotational shear imparted by rotation of the eastern Transverse Ranges), and (3) 221 5 22 km of transtensional shear within the Basin and Range province (including the 58 5 18 km of transrotational shear imported by rotation of the eastern Transverse Ranges) yields a total inferred transform displacement of 744 5 33 km), a figure which is indistinguishable from the total of 737 5 66 km anticipated from global models (Table 1).

The transrotational shear in the western and eastern Transverse Ranges, and the transtensional shear in the Basin and Range and Mojave provinces are distributed unevenly. A palinspastic reconstruction of the Basin and Range and Mojave provinces, if undertaken, would be arbitrary. There is ;429 km

41

of transform displacement, based on the analysis by Dickinson and Wernicke (1997), that is not depicted on Plates 2–8. Theoretically some of the paleolatitudes shown in these plates could be as much as 429 km farther south. However, the depiction and distribution of this calculated transform by Dickinson and Wernicke (1997) is not possible. The fossil assemblages do not suggest that any of the paleolatitudes determined in this paper are 429 km farther south. Strike-slip faulting in the Walker Lane shear zone or Walker Lane belt was not considered in the palinspastic reconstructions shown in Plates 2–8. The Walker Lane shear zone can be divided into nine structural blocks, each of which acted independently of adjacent blocks. Three of these blocks contain northwest-trending right-slip faults, three contain northeasttrending left-lateral faults, two contain no major internal strikeslip faults, and one contains east-west faults that had Mesozoic right-slip movement and minor left-lateral Cenozoic movement. The strike-slip faults in any one of these blocks rarely will extend into an adjacent block (Stewart, 1988, p. 686). Providing a palinspastic reconstruction of this shear zone is beyond the scope of this contribution and rationally beyond the scope of the meager and unreliable available slip data. The Eastern California and Walker Lane shear zones are synonymous in terms of geometry. The Eastern California shear zone is not incorporated into the reconstructions depicted in Plates 2–8. The Eastern California shear zone was depicted in Dickinson (1996, Fig. 1) and in Dickinson and Wernicke (1997, Fig. 3): they did not incorporate the shear zone into a palinspastic reconstruction of western or eastern California, although they calculated the important cumulative shear that was transmitted to the eastern California shear zone and within the Basin and Range province. The Transverse Ranges were palinspastically restored to different orientations and latitudes for each of the time slices by back rotating previously determined westward increasing paleomagnetic vectors and by considering palinspastic paleogeographic models for the Transverse Ranges and Mojave Desert proposed by others (Appendix 6B). In Plates 2C and 3C there is the following notation: “Region extended in a N-S direction in order to accommodate later compression, extension, and strike-slip faulting.” The amount that a region was extended was the amount that was needed to bring the next or younger palinspastic maps into reasonable alignment with the inferred paleoshorelines. The palinspastic restoration of the Mojave block or province was not attempted owing to the complexities outlined in Appendix 1, Table A16. It can only be assumed that a palinspastic restoration of the Mojave and eastern California areas would not affect the location of the paleolatitudes depicted in western California (Plates 2–8). There are three faults with solid barbs depicted in Plates 1–8: (1) the Sur-Nacimiento (large solid barbs); (2) the southern terminus of the San Gregorio–San Simeon–Hosgri fault zone (relatively smaller solid barbs); and (3) a low-angle fault near

42

Devils Den in the San Joaquin Valley (also with relatively smaller solid barbs). The faults are not strictly thrust faults, or they are not thrust faults everywhere because the dip of the fault plane can range from subhorizontal to 658 5 208. To be a thrust fault some structural geologists suggest that the dip of the fault plane should be ,308, while others suggest that the dip of the fault plane should be ,458. The faults are not reverse faults because the fault plane can range from subhorizontal to 458. Crouch and Suppe (1993) considered all or part of the large, solid-barb fault depicted in the outer Los Angeles basin (Plates 2C and 3C) to be a detachment fault. Herein the fault marks the sole of the southern California allochthon (Hall, 1991). The allochthon was thrust westward over the Franciscan Complex (metamorphosed to the Catalina Schist in the offshore region) between 67 and 65 Ma. For purposes of control, the Coast Range fault is depicted in Plates 1–8 (open barbs). The fault is referred to as a fault or detachment fault. Some have objected to this fault being called a thrust fault, others to it being called a reverse fault, and some to it being called a detachment fault. It marks the edge of a subduction zone (see Coast Range fault in Appendix 1, Table A16). The importance of showing the distribution of this Mesozoic fault is that it can be demonstrated to be beneath the southern California allochthon and beneath the Sur-Nacimiento fault, from northern to southern California in the palinspastically restored maps, e.g., in Morro Bay region (Plate 2C; see Hall, 1991). Other reference sources used in the construction of the paleoshoreline maps (Plates 2–8) are listed in Appendix 6C. Principal movement along the San Andreas fault system did not begin until after 8 Ma. The future location of the San Andreas fault is shown as a dashed line on maps covering the time slices from 27 to 8 Ma. McLaughlin et al. (1994) and Underwood et al. (1999) questioned the location of the San Andreas fault and continuation of right slip along the fault east of Point Delgada and through Shelter Cove. Others placed the San Andreas fault east of Point Delgada, through Shelter Cove, and credited the fault with an important role within the plate-boundary system north of Point Arena (Brown, 1995; Hart, 1996; Thatcher et al., 1997; Prentice et al., 1999). The latter interpretation was used in the palinspastic reconstructions herein. Drake et al. (1987) proposed that the Delgada fan (near lat 408N west of the San Andreas fault) grew between the latitudes of near San Francisco to near Petaluma (see Plate 8A) between 6 and 7 Ma. The offshore fan consists of ;2000 m of Miocene–Pliocene deposits southwest of the Point Arena basin and the Mendocino edge of the Juan de Fuca plate (e.g., MeFZ, Plate 8A). By ca. 2 Ma the fan deposits had moved northward 150–200 km. The slip rate on the San Andreas fault system using these figures was between 3 and 5 cm/yr. Allen (1999) proposed that the Wilson Grove Formation (Appendix 1, Table A5; Petaluma–Santa Rosa region, Plate 8A, and east of the San Andreas fault) has an age range of between 5 and 6 Ma, that the Delgada fan was at the

latitudes of the Wilson Grove Formation during the deposition of the formation, and that the San Andreas fault had separated the fan (offshore) from the formation by ;200 km. The slip rate on the San Andreas–San Gregorio–San Simeon–Hosgri fault system using these figures is 3.3 cm/yr. Prentice et al. (1999) suggested that the Holocene slip rate on the San Andreas fault near Point Delgada is 1.4 cm/yr. The Mendocino edge of the subducting Juan de Fuca plate on each of the plates (Plates 2–8) is based on Dickinson’s (1997) work. The location of the Mendocino edge of the Juan de Fuca plate on the initial palinspastic map, i.e., Plate 2C, 27– 23 Ma, is taken from Dickinson (1997). The Mendocino edge of the Juan de Fuca plate is moved northward through the time slices based on the measured slip along faults in the San Andreas fault system and on other geologic evidence. Atwater and Stock (1998, their Fig. 11) depicted the Mendocino edge of the subducting Juan de Fuca plate from 20 Ma to the present. The location of the Mendocino edge of the Juan de Fuca plate shown in the Plate 3C (23–17 Ma) time slice, based on Dickinson’s (1997) research, is in relatively close agreement with the location of the 20 Ma Mendocino edge of the Juan de Fuca plate or the edge of the Juan de Fuca plate proposed by Atwater and Stock (1998, Fig. 11). Point Delgada is near the Mendocino edge of the Juan de Fuca plate. Point Delgada was near the paleolatitude of San Francisco until between 8 and 5 Ma. For the reasons stated here, it moved northward during the time interval between 8 and 5 Ma. Note that Atwater and Stock (1998) interpolated the drift of oceanic plates in order to arrive at their Figure 11. There is very close agreement between the inferred locations of the Mendocino edge of the subducting Juan de Fuca plate at 13, 12, 8, and 5 Ma (Atwater and Stock, 1998, Fig. 11) with the locations of the edge depicted for the time slices 17–13 Ma (Plate 4B), 13–8 Ma (Plate 5B), 8–5 Ma (Plate 6A), and 5–2.5 Ma (Plate 8A), respectively. Plate 1 (in two parts) is the index map for the other plates (Plates 2–8). This plate depicts the positions of geologic and geographic features at the present time. Thus, Plate 1 serves a dual purpose—as an index map and as a reference map for comparison with the other plates. Where it was possible, i.e., where there was space for the printing of the names and regions, the full names of towns and regions are written out in Plate 1. Very rarely is there enough space on the index map (Plate 1) to write out the full names of faults. Within the explanation on each of the eight plates is written: “See abbreviations, symbols, and notes Table A16.” Appendix 1 (Table A16) is to be used in conjunction with Plates 1–8. Much of the documentation to justify or explain the bases for palinspastically restoring a region is in Table A16. There are controversies surrounding the amount of slip on all of the major strike-slip faults in western California, e.g., San Andreas, San Gregorio–San Simeon–Hosgri, Garlock, San Gabriel, Rinconada, Pilarcitos, Hayward, and Calaveras. There is controversy regarding the nature and timing of movement along major low-angle faults such as the Sur-Nacimiento and Coast Range

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines faults. It is beyond the scope here to review or summarize the various interpretations of the nature and amount of movement along these faults; however, an attempt is made to review some of the inferences or conclusions of others in the footnotes for Appendix 1 (Table A16). RESULTS The procedures to (1) organize stratigraphic units from near lat 448 to near 288N along the west coast of North America by recognizable time slices (Appendix 1, Tables A1–A6, A13); (2) standardize the taxonomy of the paleontologic data from upper Paleogene and Neogene rocks from southwestern Oregon, California, and northwestern Mexico (Appendix 1, Tables A7–A15); and (3) assign a single thermal attribute, the ET, to the northern endpoint of the geographic range of taxonomically valid taxa with living analogs (Appendix 1, Tables A7– A12) produced the following results. (1) Ranges of ET of present-day taxa can be grouped into packages of effective temperatures marking the boundaries of present-day eastern Pacific molluscan provinces and marine climatic zones (Table 1). (2) Ranges of ET of the fossil taxa can be grouped into packages of effective temperatures that most closely approximate the ranges of ET of present-day nearshore marine climatic regions in the eastern Pacific Ocean (Figs. 3–8). (3) The groupings of ranges of ET of fossil taxa can be used to define paleomarine climatic regions (Table 1), and (4) to depict fluctuations in marine paleoclimate during the past 25 m.y. (Fig. 9). (5) Based on the definitions of paleoclimatic regions (Table 1), regional climatic zones for each time slice can be assigned to latitudinal regions west and east of the San Andreas fault (Fig. 9). (6) The numerical data in Figure 7 are depicted graphically in order to visually show paleoclimatic trends (Figs. 10–26). Fossil faunal assemblages of from one to three taxa (Figs. 3–8) are not included in broader analyses because of an inadequate sample size. Faunal assemblages of 3–12 taxa are unreliable in terms of their sample size, and the analyses of some of these small fossil assemblages produce spurious results, e.g., the 11 taxa from lat 368N east of the San Andreas fault, 8–5 Ma time slice (Appendix 1, Tables A5 and A11; Figs. 9 and 25). (7) Paleoclimatic regions are assigned to the paleoshoreline maps (Plates 2–8) using the summary data in Figure 9. Analyses of the presence or absence of fossil taxa within the time slices produced stratigraphic ranges for the taxa (Appendix 1, Table A15). The youngest age ranges of some taxa are incomplete because some of the taxa may range into the Pleistocene, i.e., younger than 2.5 Ma, or Holocene. Molluscan faunas from the Pleistocene are not compared in this study with taxa having upper stratigraphic range limits of 2.5 Ma. Nevertheless, the stratigraphic range data in Appendix 1 (Table A15) provide a basis for assigning a large number of late Paleogene and Neogene taxa to a time slice and to the equivalent of a chronostratigraphic unit (stage). A complete analysis of the stratigraphic ranges of late Paleogene and Neogene (including

43

taxa that are known from Pleistocene rocks and the Holocene) pectinids and echinoderms are shown in Figures 1 and 2. These data provide important results because they show an age range or approximate age range of a large number of taxa generally considered to include a number of late Paleogene and Neogene index fossils. DISCUSSION Role of temperature in limiting distribution of marine mollusks Temperature is likely one of the major determinants of the geographic range of poikilotherms in the sea (Jablonski et al., 1985). Other environmental parameters such as dissolved oxygen, nutrients, suspended matter, and trophic activity also influence the distribution of mollusks. However, temperature is commonly considered to be the major abiotic or ecologic element limiting the distribution of nearshore mollusks. The determining temperature for survivability could be either the winter minimum or the summer maximum temperature for survival of the adult mollusk, or minimal or maximal temperatures related to gametogenesis, spawning, or physiological functions. Temperature also has an effect on oxygen consumption, feeding, and metabolic rates, and on enzyme reactions (Newell and Branch, 1980). In the bivalved mollusks Modiolus modiolus and Arctica islandica there is a two to three times increase in absorption efficiency when SSTs rise from 4.0 to 20.0 8C, i.e., there is a higher ingestion of food owing to an increase in the filtration rate with an increase in temperature (Newell and Branch, 1980). Shell growth decreases in Mytilus californianus and other mollusks with increasing latitude and decreasing temperature (Coe, 1948; Coe and Fitch, 1950; Dodd, 1964). Coe (1948) and Giese (1967, 1969) noted the importance of nutrition detritus, phytoplankton (particularly dinoflagellates and diatoms), and food availability as ecological parameters limiting the growth and distribution of mollusks. However, photosynthesis depends on solar radiation, and maximum solar radiation in the Northern Hemisphere is during spring and summer (e.g., May–July at lat 338N in the northeastern Pacific Ocean). Spring and summer are times of warming and the warmest SSTs in nearshore environments. Temperature change is linked to decline in zooplankton volume (Weinheimer et al., 1999). Loosanoff (1962), Leonard (1969), Wilson and Simons (1985), Sphigel (1989), and Cano et al. (1997) related gametogenesis and spawning to temperature, and Hall et al. (1974) related shell-growth patterns in bivalve mollusks to reproductive cycles and temperature. Cano et al. (1997) noted the importance of environmental parameters, other than temperature, in molluscan larval development; however, they concluded that spawning in the oyster Ostrea edulis only took place at temperatures of 14.0 8C or higher at lat 378408N in the Mediterranean Sea, and low levels of nutrients did not affect gametogenesis, spawning, and larval development. From their work it

44

can be inferred that duration of warmth is important in the reproductive cycle of Ostrea edulis. Larval development took place from April to September or November, but was greatest during May to July (three months) or May to September (five months) in the years sampled. Spawning of Callista chione in the Adriatic Sea (lat ;458N) is likely to occur between April and July (four months) and when the SST is warming (Riedl, 1970; Hall et al., 1974). Roy et al. (1998, p. 3699) related shared diversity-gradient patterns among gastropods living in the eastern Pacific and western Atlantic Oceans to solar energy input, average SST, and “some aspect of productivity.” Temperature, seasonal warming temperatures, and durations of warm SSTs are considered here to play the major roles in the reproductive cycle of mollusks. The basis for this inference is provided in part by observations of the reproductive cycles of mollusks (Table 6). Physiological and reproductive data that are available are largely for mollusks that are of commercial value. Few data are available for mollusks living at the northern endpoint of their geographic ranges in the Northern Hemisphere. Minimal temperatures or durations of warmth necessary for stages in the reproductive cycle, as suggested in Table 6, may limit the geographic distribution of many mollusks. However, because of the limited biologic data, the inference that duration of warmth is critical to growth and reproduction in a majority of nearshore molluscan taxa remains suggestive and, although this notion is supported by the research of Roy et al. (1998), there are exceptions. The marine bivalve Macoma balthica is panarctic, having a geographic range in the Atlantic Ocean from near lat 708 to 388N. During the coldest month of the year the SST at lat 708N is approximated to be 11.67 8C. This temperature rises to 6.14 8C during the warmest month of the year. These temperatures, or any duration of temperature, may be of secondary impor-

tance to this species, e.g., to nutrients, during its reproductive cycle and growth (see Lammens, 1967). Taxa that range into northern seas in the Northern Hemisphere have likely influenced inferences relative to the minimal importance of temperature on growth and reproduction. The bivalve Mya arenaria, for example, has a geographic range from lat 708N southward to 338N, and Swain (1952) concluded that food supply, the nature of the substrate, and the amount of dissolved oxygen in water have greater effects on growth than does temperature. However, the periods of gametogenesis and spawning in Mya arenaria are not known at the northern endpoint of the range. The mussel Mytilus californianus, which also has a geographic range of lat 598–198N in the eastern Pacific Ocean, is reported to spawn throughout the year (Dodd, 1964). This observation suggests that temperature alone is not the most important ecological parameter in the reproductive cycle of this taxon. However, it is not known if the spawning occurs during one to two months of the year at the northern endpoint of the geographic range. Spawning is reported to be continuous throughout the year in the bivalve Mytilus metcalfei, which lives from lat ;78 to 88N along the coast of the southern Philippine Islands (Tumanda et al., 1997). SSTs at those latitudes range from a winter minimum of 278 to a summer maximum of 30.1 8C; thus spawning is seemingly not dependent on temperature or a duration of temperature because the SST is warm the year around. In the Gulf of Aqaba, Red Sea, where the SST is warm throughout the year (in the Gulf of Jordan it is 19.0 8C or warmer for 12 months), reproduction was continuous throughout the year for 7 of 15 species studied. However, reproduction occurred during the warmest period of the year in another 7 of the 15 species. Of the 15 species, 1 spawned during the coldest months of the year (Hulings, 1986). Among molluscan taxa with a relatively limited geographic

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines range, the life history of mollusks seems to be strongly influenced by temperature and durations of warmth. The Pismo clam Tivela stultorum has a geographic range in the eastern Pacific Ocean from lat 388 to 258N, and gametogenesis occurs during January. However, the eggs and sperm are not ripe during January. Spawning occurs from June to December (for seven months). For three months, from September to November, larvae commonly settle onto the substrate (Coe and Fitch, 1950). Different rates of shell growth are known to occur during the year in T. stultorum. These rates are related to the reproductive cycle of the taxon and not to the coldest SSTs during the year (Hall et al., 1974). The slowest periods of shell growth occur during or following spawning in T. stultorum and in Callista chione. However, all species of bivalve mollusks do not have a biocheck or a slower period of growth related to spawning or immediately following spawning, nor do all species have a slow shell-growth period related to winter SSTs. Some oceanic thermal gradients are related to latitude. There are also latitudinal diversity gradients among mollusks. Thus, solar energy and temperature would seem to play major roles in the distribution of mollusks. The boundaries of molluscan provinces are controlled by thermal regimes, not single temperature conditions such as average SSTs. Environmental parameters, other than temperature, a range of temperatures, or duration of summer warmth, are important and can restrict the geographic distribution of some mollusks. Different environmental parameters could also be more important to a taxon living near the limits of its geographic range than within a more limited geographic range. However, in this volume, temperature and duration of warmth are assumed to be important environmental parameters controlling the distribution of many but not all nearshore marine mollusks (see Gillooly et al., 2001). The assumption is made in order to infer paleoclimatic conditions, defined by temperature values, in marine nearshore regions of California. Regional and global climatic changes Fossil molluscan assemblages indicate that marine paleotemperatures in western California decreased during late Paleogene and Neogene time (Figs. 11B, 12A, 14A, 15, 16A, 27). From 27 to 2.5 Ma there is seemingly an increase in the percentage of fossil mollusks that have modern analogs that live in a nearshore marine cool temperate climatic region, i.e., where the effective temperatures are between 10.0 and 12.0 8C (Figs. 3–8). During the same time span, there was a decrease in the percentage of fossil mollusks that have modern analogs that live in nearshore marine outer and inner tropical climatic regions, where effective temperatures are between 16.98 and 23.96 8C. Oceanic d18O increased during the deposition of a 14.8– 13.7 Ma part of the Monterey Formation (age range of ca. 17.9– 7.5 Ma) located between lat 358 and 348N along the Santa Barbara coastline and west of the San Andreas fault (DePaolo and

45

Finger, 1991). There was also an increase in deep-sea benthic d13C during the deposition of the 14.5–14.1 Ma part of the Monterey Formation (Woodruff and Savin, 1991). The significant increases in d18O from 14.8 to 13.7 Ma, and in d13C from 14.5 to 14.1 Ma represent a combination of an increase in highlatitude, cold deep water, and growth of the East Antarctic Ice Sheet (Shackleton and Kennett, 1975; Kennett, 1986a; Miller et al., 1987; Wright et al., 1992). Analyses of deep-sea d18O and d13C data from 16–13.5 Ma sedimentary rocks suggest that episodic, high-latitude, deep-water biologic production and East Antarctic ice growth can be correlated closely to the global carbon cycle (Woodruff and Savin, 1991; Flower and Kennett, 1993a). Changes in the late Paleogene and Neogene nearshore paleomolluscan fauna from western California can be correlated with a medial Miocene, global-climatic cooling trend (e.g., Fig. 27). There was a worldwide sea-level highstand between 17 and 14 Ma; worldwide rises of sea level at 6, 5, 3, and 2 Ma; and marked lowerings of sea level at 10.5, 5.5, 4.2, and 2.5 Ma (Haq et al., 1987). It is possible to suggest a correlation between some of these inferred eustatic events and glacial and interglacial climatic events, e.g., a glacial event between 7 and ca. 5.5 Ma and another between 2.5 and ca. 1.9 Ma (Shackleton and Opdyke, 1977; Shackleton et al., 1984; Harwood, 1985; Hodell and Kennett, 1986; Zubakov and Borzenkova, 1988); a regional and global lowering of sea level between ca. 7 and 5.5 Ma; and a rise in sea level at 2 Ma (Haq et al., 1987; Loomis, 1990c, p. 212, Fig. 4.11). There was a global interglacial event between 5 and 2.5 Ma. Within the same time period, however, there were two intervals during which eustatic sea level fell, and two intervals that were marked by eustatic rises in sea level. If there was an increase in high-latitude, cold deep water, and simultaneous growth of the East Antarctic Ice Sheet between 14.8 and 13.7 Ma, such events do not seem to be reflected in the short-term eustatic sea-level curves of Haq et al. (1987). A correlation between global glacial intervals between ca. 7 and 5.5 Ma with a lowering of sea level at that time seems reasonable, and a rise in sea level ca. 2 Ma and a glacial event at that time seems tenuous. With the growth of ice sheets, e.g., 14.8 and 13.7 Ma and ca. 2 Ma, it might be expected that sea level would have lowered as seawater was formed into ice. This, however, was apparently not the case in California. Thus, correlations between eustatic changes in sea level and global cooling and warming trends are open to different interpretations. Owing in part to the lack of resolution of the interpretation of paleoclimate based on fossil mollusks, correlations between eustatic changes in sea level and global periods of warming and cooling are problematic. In addition to the inability to infer short-term paleoclimatic fluctuations based on fossil mollusks, the mollusks analyzed in this study are from macrofaunal assemblages that commonly lived in embayed, estuarine, or nearshore shallow-water areas (e.g., intertidal to 150 m depths). Such environments protected them from open-ocean currents and some global climatic changes. Some of the fossil infaunal molluscan

assemblages suggest that there were oscillations in sea level, i.e., from intertidal to inner neritic to outer neritic, and repetitive oscillation cycles. However, it is not clear if these oscillations were brought about entirely by eustatic changes in sea level or in combination with regional or local tectonism. Recognizing that there are difficulties correlating global and regional paleoclimatic trends, based on nearshore molluscan assemblages, a marked regional cooling trend can be inferred to have begun between 17 and 13 Ma, particularly at latitudes north of 348N along the outer paleoshoreline of California. This cooling trend can be correlated in general with a global cooling trend that occurred between 14.5 and 14.1 Ma and was marked by the establishment of the East Antarctic Ice Sheet (Flower and Kennett, 1993a). A regional cooling trend in California, based on fossil mollusks, became more pronounced between 13 and 8 Ma, at latitudes between 348 and 338N (Fig. 27). This cooling trend can be correlated with the further expansion of the East Antarctic ice cap (Kennett et al., 1975; Shackleton and Kennett, 1975; Woodruff and Savin, 1991). Axelrod analyzed a large number of fossil floras from California and western Nevada, and assigned effective temperatures to some of these terrestrial floras: (1) an ET of 14.7 8C at lat 368N (Coalinga region) east of the San Andreas fault (Axelrod, 1980, p. 155) and an ET of 14.7 8C at 338N (in the San Diego region) west of the San Andreas fault (Axelrod and Deme´re´, 1984) (both floras are within the 5–2.5 Ma time slice); (2) an ET of 13.8 8C at 398N (east of the Lake Tahoe region) (Axelrod, 1980, p. 37) and an ET of 14.7 8C at 388N (near Turlock, Sierran foothill region) (Axelrod, 1980, p. 95) (both are east of the San Andreas fault and within the 8–5 Ma time slice); (3) an ET of 14.2 8C at 388N in the east San Francisco Bay region and east of the San Andreas fault (Axelrod, 1971, 1995) (this fossil flora is assigned an age of 11–10 Ma, i.e., within the 13–8 Ma time slice); (4) an ET of between 13 and 13.7 8C at 398N (in western Nevada) (Axelrod, 1995) and an ET of between 14.7 and 15.3 8C at 368N (in the Coalinga region) (Axelrod, 1939, 1985, 1991) (both are east of the San Andreas fault and within the 17–13 Ma time slice); and (5) effective temperatures of 12.5 and 13.3 8C at 398N (western Nevada) east of the San Andreas fault (Axelrod, 1985, 1991) (in the 23–17 Ma time slice). Except for the ET of 12.5 8C in western Nevada, all of these effective temperatures are within a mild climatic region (ET of between 13.4 and 15.5 8C) as defined by Bailey (1964, p. 8). Axelrod provided descriptive climatic information for floras at the sites mentioned here, and for other Neogene floras from California, if he did not give ET information for the fossil floras (Tables 7–10). The inferences (climate, rainfall, and floral associations) that he drew from fossil floras, which were collected relatively close to marine environments, are compared with paleoclimatic inferences based on fossil invertebrate assemblages in Tables 7–10. A note of caution must be introduced when comparing the similarities and differences between paleoclimate inferred from terrestrial fossil plants and marine invertebrate assemblages based on the research of Demko et al.

(1998): they concluded that terrestrial fossil plant assemblages can be biased toward riparian wetland environments and local hydrologic and climatologic conditions, rather than regional paleoclimate. Late late Oligocene to late early Miocene time; time slices 27–23 Ma and 23–17 Ma. Prior to 27 Ma, i.e., during the Paleocene and Eocene, the paleoclimate of Earth’s surface was warmer than at present. The paleoclimate either had higher than present winter temperatures (Miller et al., 1987; Zachos et al., 1994) or lower than present winter temperatures (Sloan and Barron, 1992; Sloan, 1994). Greenwood and Wing (1995) proposed that the Eocene Earth had a paleoclimate with much higher temperatures than present-day winter continental temperatures. They estimated that in western North America (lat 398108N), at an elevation of ,200 m, the mean annual temperature during the Eocene was either 14.4 5 2 8C or 17.1 5 1 8C. They also inferred a mean annual range in temperature of 9.4 8C and a mean paleotemperature during the coldest month of 5.6 8C. These estimated paleotemperatures are possibly too low for this latitude during the Eocene. The estimated mean annual paleotemperature of another Eocene flora was 23.9 8C at lat 368268N. This paleotemperature is significantly higher than the mean annual temperature of 14.4 or 17.1 8C estimated for the region ,38 of latitude to the north. Alternatively, the Eocene flora from 398108N might have been living at a higher elevation (see Axelrod, 1996, Fig. 2) than the elevation estimated by Greenwood and Wing (1995). Using the paleotemperature figures estimated by Greenwood and Wing (1995) for the Eocene flora at lat 398108N locality in Nevada, and Bailey’s (1964) method for estimating ET, the ET at that locality was either 14.2 or 15.4 8C. These paleotemperature figures do not seem to be in agreement with the conclusion reached by Axelrod and Raven (1985, p. 29) that northwestern Nevada, California, Oregon, and Washington were covered by a subtropical rainforest during the Eocene. In addition, Zachos et al. (1994) proposed that mean temperatures were 17.0–19.0 8C between the absolute latitudes of ;408 and 258N (but well east of California and Nevada) during the late Eocene (38–36 Ma), and they inferred that there were mean sea-surface paleotemperatures of 18.0 and 19.0 8C near lat 258N during the early Oligocene (35– 33 Ma). These paleotemperatures also suggest that the paleotemperatures at the 398108N site, calculated by Greenwood and Wing (1995), may be too low. An ET based on another and younger paleoflora (13–8 Ma time slice), and near the Eocene flora at the latitude of 398108N, was calculated to have been 14.2 8C (Axelrod, 1971, 1995). Because the paleoclimate during the Eocene was warmer than that during medial and late Miocene time (Axelrod and Raven, 1985), the paleotemperatures inferred by Greenwood and Wing (1995) from the Eocene flora at lat 398108N may either not be compatible with their inferred paleotemperatures for the sites of other Eocene floras, or their estimated altitude of ,200 m at the growing site of the flora at 398108N is too low.

Based upon several diverse sets of criteria, there is general agreement that a long-term, global decline (e.g., ;9 or 8 8C) in sea-surface and continental temperatures began during late Eocene time (e.g., Durham, 1950a; Dorf, 1955; Becker, 1961; Wolfe and Hopkins, 1967; Addicott, 1970b, 1970c; Savin et al., 1975; Savin, 1977; Axelrod and Raven, 1985; Zachos et al., 1994; Dutton and Barron, 1997). There was a major decrease (5.0 8C) in ocean bottom-water temperature when a shallow circumpolar current developed during the Eocene that thermally isolated Antarctica (Kennett et al., 1975; Kennett and Shackleton, 1976). However, even though there was a worldwide decline in terrestrial temperature during the Eocene, such a decline is not reflected in the Eocene molluscan fauna from the latitudes of California. All of the modern analogs of the Eocene molluscan genera from California are living in tropical seas (Addicott, 1970b).

The decline in worldwide temperature continued into late Paleogene time and throughout the Neogene Period. Mean annual SSTs were depressed 6.5 8C below present-day values in the tropical southwest Pacific Ocean at 10 350 yr ago (Beck et al., 1997). At lat ;34.58N in the eastern Pacific Ocean, a 3.0– 4.0 8C mean annual SST difference has been calculated for the time between the Last Glacial Maximum and modern SST values (Rosell-Mele´ et al., 1998). These calculated differences are in sharp contrast to the possible difference between the 27–23 Ma mean annual SST and modern SST values. The mean annual SST at lat 348N (palinspastically restored along the San Andreas fault) was probably only 1.5 8C higher than the modern value at the same latitude from 27 to 23 Ma. However, and more important, the winter minimum SST was probably 4.5 8C higher than the present-day value at 348N. Barker and Burrell (1976), Keller and Barron (1983), and

*W 4 west of San Andreas fault, E 4 east of San Andreas fault.

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines Pagani et al. (1999a) noted that Drake Passage, the seaway between South America and Antarctica, opened during the latest Oligocene to early Miocene (25–20 Ma). The opening of the passage is associated with global cooling, the formation of the Circum-Antarctic Current, the glaciation of Antarctica, the evolution of Neogene planktic organisms, and the eventual extinction of planktic taxa that had been common during Paleogene time (Shackleton and Kennett, 1975; Keller and Barron, 1983). However, the event between 25 and 20 Ma does not account for the marked change in the earlier Oligocene molluscan fauna and the terrestrial paleoclimate deduced from fossil floras. There was a reduction in molluscan faunal diversity during the Oligocene (35–30 Ma), i.e., earlier than the 25–20 Ma event, and there was a smaller proportion of warm water molluscan genera living along the coast of California during the Oligocene than had lived in California during the Eocene (Addicott, 1970b, p. D-7–D-8). Wolfe and Hopkins (1967) suggested that the terrestrial paleoclimate in Oregon, Washington, and southern Alaska during medial Oligocene time (ca. 35 to 30 Ma) was markedly cool. However, between 25 and 20 Ma the nearshore paleomolluscan fauna in California lived in an outer tropical paleoclimatic region. Although there is an indication of a cooling trend in California from 27 to 17 Ma (e.g., Figs. 9, 10, 12), it is difficult to either correlate the cooling trend with the opening of Drake Passage in the Southern Hemisphere, or to a possible change in the composition of nutrients for molluscan filter feeders living in the eastern Pacific Ocean of the Northern Hemisphere because the cooling trend began earlier than 25 to 20 Ma. It is inferred that the nearshore marine paleoclimate from 27 to 17 Ma in California was outer tropical, effective SSTs being 16.98–17.90 8C. The paleogeography or the configuration of the paleoshoreline of California during 27–23 Ma and 23– 17 Ma must have influenced the nearshore marine paleoclimate, the magnitude of cold water upwelling, the abundance of nutrients, and the distribution of marine invertebrate organisms (paleogeography; see Plates 2 and 3). Protected bays, peninsulas, straits, islands, and a gulf marked the paleogeography during these time intervals. These geographic features probably ameliorated regional cooling trends in open-ocean cooling circulation. However, the marine paleoenvironments from 27 to 17 Ma were restricted to embayed areas of what is now southern California (Plates 2 and 3). Fossil floras from the 27–23 and 23–17 Ma time slices are limited in number. Axelrod (1985, 1991) analyzed fossil floras from western-central Nevada that are assigned to the 23–17 Ma time slice, but none from within the 27–23 Ma time slice. He analyzed the Buffalo Canyon flora in the Buffalo Canyon Formation. Axelrod (1991) assigned an age of 18 Ma to this flora, but Wolfe et al. (1997) assigned an age of 15.6 Ma. Axelrod (1991) also studied the Middlegate and Eastgate floras in the Middlegate Formation, and assigned an age of 18.5 Ma to the formation. Wolfe et al. (1997) assigned an age of 15.5 Ma to

49

these floras. Both of these fossil floras are in Nevada near lat 398N. Because the paleofloras are in western Nevada, and east of Lake Tahoe, they are so far from the paleomarine basins of western California that comparisons between the continental paleoclimate near 398N and the protected nearshore marine paleoclimate largely south of 368N during the 23–17 Ma time slice (or 17–13 Ma if the ages of Wolfe et al., 1997 are used) are not meaningful. Nevertheless, the Buffalo Canyon flora consists of a mixed-conifer flora that lived at elevations of ;1280 m (Axelrod, 1991) or 3200 m (Wolfe et al., 1997), and a broad-leaved evergreen forest that was growing on warmer and drier sites in the same region. The Buffalo Canyon flora lived in a relatively cool climatic region with an ET of 12.5 8C. Species in this fossil flora have allied taxa that are living today in the Klamath Mountains of northwestern California (Axelrod, 1991). A sclerophyll or hard-leaf flora that formed an understory beneath a mixedconifer flora characterized the Middlegate and Eastgate paleofloras. These floras lived in a mild climatic region (ET of 13.3 8C) (Axelrod, 1985) at elevations of 2700–2800 m according to Wolfe et al. (1997). Late early Miocene to early medial Miocene time; time slice 17–13 Ma. Addicott (1969a, 1970b, Fig. 5) and Marincovich (1984) suggested that both a regional warming trend in SSTs and an overall global decline in SSTs occurred in western California during medial Miocene time (19.5–12 Ma or 17–15 Ma). However, evidence for a broad regional warming in contrast to local warming trends ca. 17 Ma is not evident from the analyses of molluscan assemblage in this volume (e.g., Figs. 22 and 27). There is a slight increase in the percentage of inner tropical taxa at some latitudes during late early Miocene to early medial Miocene time. However, there is a decline in the percentage of outer tropical and warm temperate taxa when compared with the faunal character of the 23–17 Ma time slice. In addition, Axelrod and Raven (1985) noted the appearance of deciduous hardwood forests and a cooling paleoclimate during medial Miocene time in the western interior of Oregon, Idaho, and Nevada. Savin et al. (1975) and Savin (1977) proposed a sharp decline in bottom seawater temperatures in northern latitudes of the Northern Hemisphere from 17 to 15 Ma. The decline in temperature is coeval with the onset of major glaciation in East Antarctica during medial Miocene time. Polar cooling occurred between 17.8 and 13.5 Ma (Barron, 1985), and global cooling took place from 14.5 to 14.1 Ma (Flower and Kennett, 1993a). Regional and diverse medial Miocene floras changed markedly between 14 and 13 Ma owing to a drastic decrease in summer rainfall (Axelrod, 1985, 1991). The decline in rainfall spread over the entire region west of the Cordillera (13–12 Ma) (present-day East Asia genera were largely eliminated from the region) (Axelrod and Raven, 1985). There was still ample summer rainfall to support chaparral species during late Miocene and Pliocene time, and chaparral species later adapted physiologically to a dry summer climate (Axelrod and Raven, 1985). There was also a worldwide sea-level highstand between 17 and 13 Ma (Haq et al., 1987). The decline in bottom seawater

temperatures, drop in the highstand of sea level, and marked decrease in summer rainfall correlate with an increase in cool temperate taxa in fossil molluscan assemblages from southern California (Fig. 27, 17–13 Ma time slice), but not with a warming trend, although molluscan extinction rates were high during the 17–13 Ma time interval (Fig. 28). Based on the analysis of 17–13 Ma fossil marine molluscan faunas from many localities in western California, isotopic evidence, analyses of medial Miocene microfaunas, and fossil floras, it is suggested here that the warming trend during medial Miocene time (with a duration that lasted from 19.5 to 12 Ma, or between 17 and 13 Ma herein) proposed by Addicott (1969a; 1970b, Fig. 5) and Marincovich (1984), although well founded by their data, perhaps reflects a local phenomenon (e.g., Fig. 15B; lat 378N, east of the San Andreas fault). Perhaps this was a local phenomenon related to paleogeography, i.e., to a protected embayment in the San Joaquin Valley region from 17 to 13 Ma (Plate 4B). The warming spike during medial Miocene time, depicted by Addicott (1970b, Fig. 5), is based only on a single fossil molluscan assemblage from the southern San Joaquin Valley. A warming trend is also depicted in Figure 15B (see 17–13 Ma time slice at lat 378N, east of the San Andreas fault) for the same local area. However, from the regional and global analyses presented herein, and the regional paleoclimatic trends based on fossil mollusks from several latitudes both east and west of the San Andreas fault, no regional warming trend during medial Miocene time in nearshore areas of California is apparent (e.g., Fig. 22, see particularly lat 378N, west of the San Andreas fault; and Fig. 27). Future research may resolve the different conclusions reached by Addicott (1969a, 1970b) and Marincovich (1984) with those reached herein that include a broad range of latitudes east and west of the San Andreas fault. The Transverse Ranges underwent clockwise rotation from 17 to 8 Ma that possibly continued to 5 Ma. Rotation began to change the configuration of the shoreline of the protected AnaVent marine basin (Fritsche, 1998) (Plate 2C) into a more open-coastal environment (Plates 3C and 4C). The worldwide rise in sea level between 17 and 13 Ma (Haq et al., 1987), along with regional tectonism in California (Dickinson, 1997), accounted for submergence and development of the embayed California coastline (e.g., Plate 4). New coastal environments were created during this time interval; their development was concurrent with the opening of new environmental niches and an increase in the diversity of marine organisms; i.e., from 345 taxa in the 23–17 Ma time slice to 515 taxa in the 17–13 Ma time slice, and to 631 taxa in the 13–8 Ma time slice (Appendix 1, Tables A8–A10; e.g., see 368–358N east of San Andreas fault, Appendix 1, Table A9). Montgomery (2000) also reported increased diversity among species of Pacific salmon between 20 and 6 Ma. The organisms living in the outer tropical paleoclimatic region that had been living in marine environments along the protected coastline of California from 27 to 17 Ma were able to survive in the protected warm waters that existed in southern California from 17 to 13 Ma (see Plate 4C). Although

global cooling took place from 14.5 to 14.1 Ma (Flower and Kennett, 1993a) or later, the protected coastal fauna was not greatly affected by the cooling trend, and the fauna became more diverse because of an increased number of environmental niches. From 17 to 8 Ma, the open and unprotected coastal region of California supported a relatively cooler water marine fauna than did the protected coastal areas (see Plate 4). In addition, upwelling is inferred to have been present along the open west coast of North America during medial Miocene time (17– 13 Ma) (Scotese and Summerhayes, 1986). Late medial Miocene to early late Miocene time; time slice 13–8 Ma. Marincovich (1984) also proposed a warming event during the “Margaritan” Age (12.5–11 Ma). Such an event is not supported in this study or by others. Kennett (1986a) proposed a period of worldwide increased cooling between 12.5 and 11.5 Ma, and another period of increased cooling between 11 and 9 Ma. The age assignments of marine mollusks in this study are not sufficiently precise in order to indicate two periods of cooling in the marine nearshore environments of California during late medial and early late Miocene time. However, there was a sharp increase in the number of cool temperate marine taxa in assemblages from southern California between 13 and 8 Ma (Fig. 27). The same fossil molluscan assemblages showed a sharp decrease in the number of fossil mollusks with warm temperate, outer tropical, and inner tropical present-day analogs, although there was a local increase in the percentage of inner tropical taxa at lat 348–338N west of the San Andreas fault (Fig. 27, 13–8 Ma time slice). These changes in molluscan assemblages can be correlated with the development of the modern pattern of deep-water circulation in the eastern Pacific between 13.5 and 12.5 Ma (Keller and Barron, 1983), but not with a regional or multilatitudinal warming event. Worldwide sea level was lowered sharply between 13 and 8 Ma (Haq et al., 1987). This change in eustatic sea level does not seem to be reflected in the configuration of the paleocoastline of California, which remained embayed during this entire period of time (Plate 5). The 13–8 Ma fossil assemblage from the southern San Joaquin Valley (lat 368–358N east of San Andreas fault, Appendix 1, Table A10) is considered here to be a relict fauna that survived, or was able to adapt, during the Neogene cooling trend. The marine fauna from this region lived in a protected embayed environment, and the shallow-water environment allowed for survival and seasonal periods of warmth sufficient for reproduction (paleogeography; see Plate 5B). Addicott and Vedder (1963, p. C-64–C-65) characterized the molluscan fauna from this region as being tropical and one that lived in a thermal regime analogous to the present-day outer coast of southwestern Baja California Sur, Mexico, and based their conclusion on the following taxa: Bivalvia Dosinia ponderosa Schumacher, ex Gray, Lyropecten sp., Miltha xantusi (Dall), “Phos” dumbleana Anderson; and Gastropoda Cancellaria lickana Anderson and Martin, C. cf. C. pacifica Anderson, Cancellaria s.s., Ficus

Figure 28. A: Extinction of California marine fossil macroinvertebrate species (Appendix 1, Table A15). There were two intervals of time during Neogene when large number of molluscan species became extinct, 17–13 Ma and 5–2.5 Ma or 5 Ma to Pleistocene time. These time intervals correspond to significant cooling, warming, and tectonic trends or events, but seemingly not to sea-level lowstands. Global paleoclimatic and regional tectonic events (25.0–1.9 Ma) are keyed to extinction events listed in Table 11: asterisk—events between 5.5 and 1.9 Ma to account for extinction of 257 marine species (29% of fauna) from 5 to 2.5 Ma, or late Pliocene to Pleistocene time interval; pound sign—events between 9.0 and ca. 6.0 Ma and during 8–5 Ma time interval to account for extinction of 127 taxa (22% of fauna); double asterisk—events between 13.0 and 7.0 Ma that could account for extinction of 188 species (30% of fauna) during 13–8 Ma time interval; double pound sign—events between 17 and 13.0 Ma to account for extinction of 234 species (45% of fauna) during 17–13 Ma time interval; triple asterisk—events between 23.0 and 17.0 Ma to account for extinction of 71 marine species (21% of fauna) during 23–17 time interval; triple pound sign—events between 29.0 and 20.0 Ma to account for extinction of 81 marine species (29%), primarily mollusks living 27–23 Ma. Note that 17–13 Ma time interval is marked by climatic optimum between 17 and 15 Ma and global cooling between either 14.8 or 14.5 Ma and either 14.1 or 13.0 Ma (see Table 11). B: Extinction rates during time slices. Extinction rates are measured as re 4 (1/D). (E/D), where D is diversity or number of taxa per interval of time Dt, and E is number of extinctions (Sepkoski, 1978, p. 225; Pearson, 1992, p. 117). C: Note correlation between appearance of new taxa (largely marine molluscan species from California) between 17 and 13 Ma, 13 and 8 Ma, 8 and 5 Ma, and 5 and 2.5 Ma and relatively high rates of extinction of molluscan species during same time intervals.

(Trophosycon) ocoyana (Conrad), Oliva sp., Turricula sp., and Turritella cf. T. vanvlecki Arnold. These same taxa are also present in 17–13 Ma rocks between lat 368 and 358N east of the San Andreas fault (Appendix 1, Table A9; Plate 4B). The 17–13 Ma taxa are Miltha xantusi (Dall), a species that lives in water 55 m or deeper; M. (M.) sanctaecrucis (Arnold); Phos (Antillophos) posunculensis (Anderson and Martin), the subgenus Antillophos, lives in water depths of 37–402 m; and Ficus (Trophosycon) kerniana (Cooper) (living species of Ficus are present as beach shells and offshore). At least two species of Turricula are present in the 17–13 Ma time slice (the genus lives in water depths from 46 to 280 m); five species of Turritella are present in the 17–13 Ma time slice (living species of

Turritella are found in depths from 4 to 170 m); also present are Cancellaria (Pyruclia) lickana Anderson and Martin (the subgenus Pyruclia lives offshore to depths of 37 m); Cancellaria (Euclia) pacifica Anderson (the subgenus lives between low tide and 37 m); 15 species of Cancellaria (species of Cancellaria are living in the intertidal zone to 550 m); two species of Oliva (present-day species of Oliva (Oliva) live in the intertidal zone and in deeper water); species of Lyropecten (today the genus lives within the intertidal zone to 110 m); Dosinia ponderosa Schumacher, ex Gray (the species lives offshore to depths of 60 m); and two other species of Dosinia. These taxa are present in the 17–13 Ma rocks near the same latitude as the 13–8 Ma taxa that were characterized as tropical by Addicott

C.A. Hall Jr.

and Vedder (1963). In addition to the taxa listed by Addicott and Vedder (1963) to support their conclusion that the fossil fauna from rocks within the 13–8 Ma time slice and from the southern San Joaquin Valley indicate that the fossil fauna was living in an outer tropical climatic region, there are another two taxa known from the 17–13 and 13–8 Ma assemblages from this area. These are Here (Here) excavata (Carpenter), a species that lives at depths to 110 m; and Calyptraea (Calyptraea) mamillaris Broderip, a species that lives on mudflats and attached to rocks (Appendix 1, Table A9). The endpoints of the present-day geographic ranges of these two taxa are lat 258N and 58S. Only two taxa in the 13–8 Ma faunal assemblage from the southern San Joaquin Valley, i.e., taxa whose modern analogs are living today in the outer tropical climatic region, are not present in rocks from the same region assigned to the 17–13 Ma time slice. These two taxa are Daphnella sp., species of which live in water depths from 20 to 200 m, and Trigonostoma sp., species of which live in water depths of a few meters to offshore (Appendix 1, Table A9). Thus, in this study the outer tropical elements of the 13–8 Ma molluscan fauna from the southern San Joaquin Valley are considered to be relict outer tropical faunal elements, based on the paleogeography of the southern San Joaquin Valley, the distribution of fossil mollusks that indicate a warm temperate marine paleoclimate, and the presence of all but two of the 13–8 Ma outer tropical mollusks in 17–13 Ma rocks from the same region and latitudes. The relict outer tropical fauna survived in this region because of the favorable biogeographic conditions. The same conditions were not present along the open, unprotected 13–8 Ma coastal and warm temperate climatic region located farther west at the same latitude. Late Miocene to early Pliocene time; time slice 8–5 Ma. Stanton and Dodd (1970, p. 1106) (samples at ;368N, east of the San Andreas fault) concluded that seawater temperatures during the deposition of the Patinopecten, Macoma, and upper Pseudocardium faunal zones had a temperature range of between 11.5 and 18.0 8C, based on isotopic analyses of molluscan shells. Using their figures, an ET of 14.5 8C can be calculated for this region. An ET of 14.5 8C is comparable to effective temperatures within the southernmost Oregonian molluscan province or the nearshore temperate paleoclimatic region. The molluscan fauna between the latitudes of 378 and 368N, east of the San Andreas fault, is also assigned to a nearshore temperate paleoclimatic region and it is near the warm temperate–temperate paleoclimatic boundary (Fig. 9; Appendix 1, Table A11). The extraprovincial taxa in the small assemblage of fossil taxa (11 taxa) from near ;368N east of the San Andreas fault may bias the paleoclimatic analysis toward warmer conditions than those that actually existed (Fig. 23; Appendix 1, Table A11). The paleogeographic maps, and the fossil assemblages to the north and west of the San Andreas fault at this latitude, seem to resolve the problem by providing a better regional understanding of the paleogeography and the distribution of the bulk of the fossil mollusks, modern analogs of which live in

the temperate climatic region (Appendix 1, Table A11; Plates 6B and 7). Early to late Pliocene time; time slice 5–2.5 Ma. The San Joaquin Formation, which includes the Cascajo Conglomerate Member and the Broken Hill flora, is present east of the San Andreas fault between lat 378 and 358N in the Coalinga region. The formation contains several fossil molluscan taxa whose modern analogs range from either 338, 368, or 378N northward along the present-day west coast of North America. These taxa are the Bivalvia Clinocardium sp., Mya (Arenomya) arenaria Linnaeus, Mya cf. M. dickersoni Clark, Patinopecten healeyi (Arnold), and Patinopecten lohri (Hertlein) (Appendix 1, Table A12). There are also several other taxa in faunal assemblages from the San Joaquin Formation having modern analogs that range south from either 308, 298, 278, 258, 248, or 238N, i.e., the Bivalvia Argopecten ventricosus (Arnold), Anadara (Anadara) trilineata (Conrad), Lyropecten terminus (Arnold), Placuanomia californica Arnold, Protothaca grata (Say), Semele flavescens (Gould), and the Gastropoda Calyptraea (Calyptraea) mamillaris Broderip (Appendix 1, Table A12). Thus, there is a mixed cold and warm water molluscan assemblage present in the San Joaquin Formation. On the basis of strontium content in mollusk shells, Stanton and Dodd (1970, p. 1106, Table 4) suggested that the paleotemperature range of water during the deposition of the San Joaquin Formation (their upper Mya and Acila zones) was between 11.5 and 18.5 8C. There is not a comparable range of temperatures along the present-day coastline of California. The geographically closest temperature range to parallel it is north of Point Conception (lat 34.58N). The region north of Point Conception is in the Oregonian molluscan province, and in a temperate climatic region (Table 3). Stanton and Dodd (1970) and Dodd and Stanton (1975) also concluded that the paleosalinities at his latitude, and within the 5–2.5 Ma time slice, ranged from normal marine (35‰) to brackish water (10‰–15‰). Axelrod (1980, p. 157) proposed that there was a terrestrial annual paleotemperature range of between 11.1 and 20.0 8C, and an ET of 14.7 8C, during the deposition of the San Joaquin Formation (Broken Hill flora) in central California (;368N). Axelrod (1980, p. 155) placed the Broken Hill flora within the same thermal field that is present on land in the Santa Barbara (;34.58N) to Escondido (;33.58N) region south of Point Conception today. The present-day winter minimum SST along the coastal part of the Santa Barbara to Escondido region is ;12.0 8C; the summer maximum is ;23 8C; and the ET is 15.51 8C, or slightly higher (the coastal region is within the California molluscan province) (Table 3). However, based on the analysis presented in this volume, the San Joaquin Formation near lat 368N and east of the San Andreas fault was deposited in a temperatemarine paleoclimatic region with effective temperatures between 12.64 and 13.94 8C, i.e., the formation was deposited in a thermal regime analogous to that located north of the latitude

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines Point Conception (34.58N), and within a molluscan province analogous to the Oregonian molluscan province (Figs. 8, 9, 12A, 26, and 27). The marked increase in the molluscan fauna whose northern endpoints are in areas with cool-temperate effective temperatures supports this conclusion (e.g., Fig. 26). The fauna, represented by a relatively small number of warm water mollusks in the fossil assemblage, is considered here to be part of a relict fauna that survived in the protected and shallow San Joaquin marine basin (during deposition of the San Joaquin Formation), and part of the warm water assemblage that had existed in the basin from at least 13 Ma or earlier. Adegoke (1969, p. 53) and Marincovich (1984, p. 72) suggested that a late Neogene warm water event in the northeastern Pacific Ocean took place from 6.5 to 3.5 Ma (i.e., during the 5–2.5 Ma time slice). Marincovich (1984, p. 70) also concluded that a warm temperate paleoclimate at lat ;368N could be inferred “by a mean paleotemperature of 14 8C derived from an analysis of strontium concentration in the outer shell layer of Mytilus specimens from the Etchegoin (late Miocene and Pliocene age) and San Joaquin (early Pliocene age) Formations (Stanton and Dodd, 1970).” Durham (1950a) depicted a slight late Pliocene climatic warming. Addicott (1970b, Fig. 4) depicted a marine warming event during the Pliocene, but the event was not depicted in his Figure 5. Addicott (1970b, p. D11) concluded the following: Zoogeographic analysis of the Pecten coalingensis zone fauna of Woodring, Stewart and Richards (1940) and qualitative evaluation of the much smaller assemblages from their other San Joaquin faunal zones suggests that marine surface-water temperatures were comparable to those occurring in the southernmost part of the modern Oregonian molluscan province off of central California. In other words, the marine climate was as warm as or perhaps slightly warmer than occurs at this latitude today. The present analysis is in accord with Barbat’s and Galloway’s (1934) belief that the succession of Jacalitos and Etchegoin faunas evidence progressive cooling and with Durham’s (1950) similar conclusion on the relationship of Etchegoin to San Joaquin faunas. The slight late Pliocene climatic warming inferred by Durham (1950, p. 1259, fig. 3) [and Adegoke, 1969, p. 53] based upon mollusk and coral identifications from northern California, was negated after reidentification of the supposed warm water taxa and a zoogeographic analysis of the associated fauna indicated that the fauna as a whole suggest somewhat cooler temperatures than occur at that latitude today (Allison and others, 1962).

Repenning and Brouwers (1992) concluded that the Arctic Ocean borderland underwent continental glaciation twice between 3.0 and 0.85 Ma. They also inferred that the maximum age for the opening of the Bering Strait was ca. 3.0 Ma. However, Marincovich et al. (1999) suggested that the Bering Strait was open by 5.5 Ma. A regional tectonic event or eustatic change in sea level that could have influenced the marine paleoclimate and the faunal makeup of the molluscan faunas in California occurred from 5 to 2.5 Ma. Prior to 3.5 or 3.1 Ma there were one or more

53

seaways through Central America that provided marine migration routes (Webb, 1978). These transoceanic routes between the Atlantic and the Pacific Oceans were closed by 3.5 Ma (Saito, 1976), 3.1 Ma (Keigwin, 1978), as late as 3–2 Ma (Woodring, 1966) or late Pliocene (Beu, 2001, p. 715). The conclusion reached by Addicott (1970b), i.e., that marine surface-water temperatures during the deposition of the San Joaquin Formation (,5 Ma, Table 11) (the San Joaquin Formation is above the Etchegoin Formation, which is assigned ages between 7.5 and ca 5 Ma), is in agreement with that reached herein. SSTs during the deposition of the San Joaquin Formation were comparable to present-day SSTs in the southernmost part of the modern and temperate Oregonian molluscan province (Fig. 9; Table 3; Plate 8). Whichever date for the opening of the Bering Strait is correct, 3.0 or 5.5 Ma, the opening event, along with the closure of the transoceanic routes between the Atlantic and Pacific Oceans within this time frame, must have strongly influenced the distribution of the eastern Pacific molluscan fauna. Pleistocene time; 1.6–0.01 Ma. Valentine and Meade (1961), in their analysis of Pleistocene molluscan assemblages, concluded that early Pleistocene paleotemperatures in southern California (;348N) were cooler than today and nowhere warmer than today. They also concluded that late Pleistocene paleotemperatures were both warmer and cooler than today. However, Muhs and Kyser (1987) concluded that late Pleistocene paleotemperatures of seawater off southern California from ca. 125 ka to the present were 2.2–2.4 8C cooler than today (present-day mean annual temperature of ;16 8C). Note that they calculated the paleotemperatures from the isotopic composition of late Pleistocene mollusk shells. These paleotemperatures provide information relative to the mean annual sea-surface paleotemperature during the late Pleistocene, but they do not provide minimum and maximum paleotemperature data or the mean annual range in sea-surface paleotemperatures. It is not possible to calculate ET from their isotopic temperature data, and the mean annual SST is considered here to be of lesser biological or physiological significance to the life history of most mollusks than minimum and maximum seawater temperatures and the duration of warmth of seawater water during reproductive and growing cycles. It is assumed here that shell growth and reproduction during spring and summer is more common than during winter months (Hall et al., 1974). It is recognized that there are exceptions to these growing cycles, e.g., Mytilus californicus, whose maximum growth is during winter months (Killingley and Berger, 1979). Table 11 lists late Paleogene and Neogene paleoclimatic trends both on a global scale and for the entire northeastern Pacific Ocean, based on microfossils and isotopic studies. Barron and Keller (1983) outlined 14 cold and 12 warm paleoclimatic events that took place in the northeastern Pacific Ocean during medial and late Miocene time (between 15 and 5 Ma). These and other paleoclimatic events, based on stable isotope

Global, oceanic, open-ocean, and regional paleoclimatic trends; and regional tectonic events that are likely to have played a role in the distribution and extinction of nearshore marine molluscan assemblages in western California from 27 to 2.5 Ma or 27 to 1.9 Ma. Mean annual sea-surface temperatures between 13.6 and 13.8 8C at lat ;348N; mean annual temperature at this latitude today is 16 8C (Muhs and Kyser, 1987). Cooling of Pacific Ocean during Pleistocene based on planktic Foraminiferida (Ingle, 1967, 1976). Isthmus of Panama emerged briefly between 3.1 and 2.0 Ma; there was closure for the final time ca. 2.0 Ma, resulting in an increase in the velocity of the oceanic circulation in the North Atlantic (Cronin and Dowsett, 1996). Glacial event (Shackleton and Opdyke, 1977; Zubakov and Borzenkova, 1988). Cooling of Pacific Ocean during late Pliocene time based on planktic Foraminiferida (Ingle, 1967, 1976). Cooling of Pacific Ocean at high latitudes at 2.6 Ma (Barron, 1992). Major cooling step. Closure of Panamanian seaway (Barron and Ingle, 1999). Opening of Bering Strait (Repenning and Brouwers, 1992) (see 5.5 Ma). Isthmus of Panama a complete marine barrier (Coates and Obando, 1996, p. 21) Glaciation in Sierra Nevada, California (Gillespie, 1982), 1000 m of crestal uplift occurring since 3 Ma (Small and Anderson, 1995; see Huber, 1981; Chase and Wallace, 1986). Wernicke et al. (1996) suggested that this range was initially 4000–5500 m (ca. 20 Ma) and then it subsided to 2000–3000 m during the late Cenozoic (ca. 10 Ma). Wakabayashi (2000) suggested that crestal uplift began ca. 5 Ma and that it was 1440–2150 m. Chamberlain and Poage (2000) suggested that the Sierra Nevada has been at its present elevation since at least 16 Ma. Colder sea-surface waters in Pacific Ocean beginning at 3.2 Ma (Shackleton and Opdyke, 1977; Keller, 1979). Increasing amplitude of glacial-to-interglacial bottom-water temperature change from 3.2 to 2.3 Ma (Dwyer et al., 1995). High eustatic sea level (ca. 35 m higher than previously, ca. 3.5–2.5 Ma) (Dowsett and Cronin, 1990). Compression along reverse faults and folding east and west of San Andreas fault occurred ca. 3 Ma (McCrory et al., 1995). The blind thrust and reverse faults associated with the 1987 Whittier Narrows and 1994 Northridge earthquakes, the Elysian Park and Puente Hills faults east of the Los Angeles Civic Center, and the active fault system along the Wilshire Boulevard corridor in west Los Angeles are structural features that postdate the initiation of the change in plate motion at 6, 5, or 3.5 Ma. Meteorite impact in Argentina and associated extinction (Schultz et al., 1998) occurred. Transoceanic route between Atlantic and Pacific Oceans closed (Saito, 1976; Keigwin, 1978). Uplift and erosion of the California Coast Ranges, most severe folding since the Mesozoic. Change in plate motions off California coast (Harbert and Cox, 1989; Harbert, 1991). This event is considered by Behl and Ingle (1998) to have been earlier, i.e., between ca. 6 and 5 Ma. The distribution of earlier ocean basins in California was probably more extensive than shown in Plates 2–7 owing to this period of uplift and erosion that removed marine deposits older than those of Pliocene age. Compressional thrust faulting and structural thickening in western California (Behl and Ingle, 1998). Warming of surface waters of Pacific Ocean (Keller, 1979). Extinction rates among North American mammals were high; however, 37 new mammalian genera appeared at this time in addition to the 63 North American mammalian genera that became extinct during late Hemphillian time (Prothero, 1999). High-latitude ocean warming (Barron, 1992). Weakening of California Current (Barron and Ingle, 1999). Worldwide interglacial paleoclimatic events (Hodell and Kennett, 1986). Worldwide glacial paleoclimatic events (Hodell and Kennett, 1986). Cooling but oscillating sea temperatures; lowering of eustatic sea level (Keller and Barron, 1983). 87Sr/86Sr ratios of planktic foraminifers increase between 5.5 and 4.5 Ma (Hodell et al., 1989).

San Andreas fault or fault zone (SAF). Initial slip on the central part of the SAF began at 12 or 13 Ma, which is the approximate time of the initial movement on the San Gabriel fault. Slip on the northern part of the SAF could have begun later than 12 or 13 Ma. Slip on the southern SAF initiated ca. 6 Ma. Slip was related in part to transrotation of the western Transverse Ranges. Significant slip along the northern SAF and Rinconada faults occurred after 10 Ma. Slip of 315 5 10 km along the central SAF and slip on the southern SAF of 240–270 km.

studies and microfossils, doubtless played a role in the distribution patterns of marine mollusks from 27 to 2.5 Ma in western California. Oscillations in paleoclimate based on fossil mollusks between latitudinal intervals in the same time slices (e.g., Figs. 23 and 25) could possibly reflect some of the paleoclimatic oscillations outlined by Barron and Keller (1983); however, such interpretations are open to question because of the relatively low level of resolution of paleoclimatic fluctuations based on the distribution of nearshore mollusks in contrast with interpretations of changes in paleoclimate based on more numerous microfossils, microfossils in deep-sea drill cores, and isotopic temperatures (Table 11). Whether the late Paleogene and Neogene molluscan assemblages reflect the paleoclimatic oscillations documented by others, many of those paleoclimatic events must have played a major role in controlling the distribution of fossil mollusks in California, and the presence of extraprovincial mollusks in fossil assemblages. Extralimital and extraprovincial or thermally anomalous molluscan taxa The geographic endpoints of many Neogene mollusks do not coincide with their present-day latitudinal ranges. These species in the fossil record are extralimital and they may have only migrated intraprovincially. However, some fossil molluscan species or taxa migrated across paleoclimatic or paleomolluscan boundaries—these are extraprovincial taxa. Extraprovincial molluscan taxa are present in Neogene molluscan assemblages from California. Extraprovincial and mixed warm and cold water or thermally anomalous taxa in molluscan assemblages of late Paleogene and Neogene age in California are present in rocks assigned to the 17–13 Ma time slice. Nine extraprovincial taxa, representing 1.7% of all of the species reported from upper lower Miocene to lower middle Miocene rocks from California (Appendix 1, Table A9), are known from this time slice. There are 14 extraprovincial taxa, i.e., 2.2% of the species reported from upper middle to lower upper Miocene rocks at several latitudes in palinspastically restored western California, known from the 13–8 Ma time slice. However, it was during the time interval from 8 to 5 Ma that extraprovincial species became relatively more abundant. Of all of the species reported from upper Miocene and lower Pliocene rocks in California, 62 (;11%) are extraprovincial taxa (or an average of one extraprovincial species became extinct every ;42 k.y.). This percentage is similar to the percentage of extraprovincial species from Pleistocene deposits in California, i.e., 90 of 750 species (12%) (Roy et al., 1995), or an average of one Pleistocene extraprovincial taxon became extinct every 17 k.y. However, conclusions regarding extinction rates based on this type of comparison could be spurious because many of the extraprovincial Miocene–Pliocene taxa are identified only to the generic level, whereas the Pleistocene extraprovincial taxa are extant species. Extraprovincial taxa from rocks assigned to the time slices

from 17 to 5 Ma are discussed in the following, beginning with the 17–13 Ma time slice in order to emphasize the dramatic appearance of a relatively large number of extraprovincial taxa during the time interval from 8 to 5 Ma. The 8–5 Ma time slice represents an interval of time that followed a worldwide sharp decline in ocean temperatures, a sharp regional decline in nearshore marine paleotemperatures in the eastern Pacific Ocean, and a marked change in the configuration of the California coastline that resulted from tectonism and the clockwise rotation of the western Transverse Ranges. The near completion by 8 Ma, or between 8 and 5 Ma, of the clockwise rotation of the Transverse Ranges would have strongly influenced the California Current and the distribution of geologically younger nearshore marine organisms. Several of the same extraprovincial and extratropical taxa are present in rocks assigned to the 17–13, 13–8, and 8–5 Ma time slices. These taxa were not confined between their presentday geographic endpoints until after 2.5 Ma. These taxa are identified in Table 12 by an asterisk. The repeated presence of these extraprovincial taxa in rocks from several time slices suggests that the geographic distribution of these taxa in the past either was not limited by narrow temperature tolerances for growth and reproduction, winter minimum temperatures, or local biogeographic conditions that allowed for their presence and reproduction. The first records of extraprovincial or extratropical taxa from 17 to 5 Ma are identified by a dagger in Table 12. An inference drawn from these first occurrences is that as Northern Hemisphere sea-surface paleotemperatures at high latitudes cooled, sea-surface paleotemperatures at low latitudes warmed, and the number of nearshore environmental niches increased, there was an increase in the diversity of molluscan species living in the eastern Pacific Ocean. A relatively large number of the extraprovincial taxa listed in Table 12 live in shallow water. Extraprovincial taxa that live in shallow waters, i.e., intertidal to 5 m, commonly have extensive geographic ranges and physiological tolerances; these species are preadapted for extensive migration (Roy et al., 1995, p. 1072). Between 17 and 13 Ma, mollusks occupied a nearshore outer tropical paleoclimatic and protected shoreline region south of lat 378N, and a warm temperate paleoclimatic and protected shoreline region between 398 and 378N east of the San Andreas fault (Plate 4). At the same time, mollusks also occupied a palinspastically restored, nearshore outer tropical paleoclimatic and relatively open coastal region south of lat 368N, and a warm temperate paleoclimatic and relatively open coastal region between 388 and 368N; both regions are west of the San Andreas fault. However, between the absolute latitudes of 388 and 368N west of the San Andreas fault, and between latitudes of 398 and 378N east of the San Andreas fault, Lyropecten crassicardo (Conrad) and L. estrellanus (Conrad) are present with the otherwise warm temperate molluscan faunas (Appendix 1, Table A9). These species are extratropical because species of

Lyropecten are living today in the Gulf of California, and the genus has a present-day latitudinal range from lat 258N in the Gulf of California southward to near the equator. The winter minimum temperature near 258N in the Gulf of California is between 17.40 and 20.0 8C, and the ET is 17.78 8C or warmer. Lyropecten is living today in an outer tropical climatic region, but it was living in both outer tropical and warm temperate paleoclimatic regions from 17 to 13 Ma. There are six or seven other extratropical taxa among the 17–13 Ma warm temperate molluscan assemblages (Table 12; Appendix 1, Table A9). The northern extraprovincial bivalve Patinopecten (10–275 m) first appeared in the fossil record in California between 17 and 13 Ma (Table 12). The extinct species Patinopecten propatulus (Conrad), P. haywardensis (Lutz), and P. haywardensis calaverasensis (Hall) are present in 17–13 Ma rocks that were deposited in an elongate bay between lat of 388 and 378N east of the San Andreas fault. The northern endpoint of the presentday geographic range of Patinopecten is 598N; the southern endpoint is at 368N. Thus, today Patinopecten lives within the Oregonian or Oregonian-Aleutian molluscan province and in nearshore temperate to cool temperate marine climatic regions. However, fossil species of this genus were living within a molluscan province analogous to the Californian molluscan prov-

ince, i.e., within a warm temperate paleoclimatic region between 17 and 13 Ma. This is the only northern extraprovincial taxon that is present in 17–13 Ma fossil molluscan assemblages at any latitude in California. There are 10 extratropical or southern extraprovincial taxa among the 13–8 Ma warm temperate fossil assemblages that are from palinspastically restored regions west and east of the San Andreas fault, and among the cold temperate fossil faunas east of the San Andreas fault (Table 12). The bivalve Lyropecten crassicardo (Conrad), L. estrellanus (Conrad), and the gastropod Ficus (Trophosycon) kerniana (Cooper) are present in warm temperate fossil molluscan assemblages in palinspastically restored regions west of the San Andreas fault. The southern tropical bivalve species Here (Here) excavata (Carpenter), Lyropecten crassicardo (Conrad), L. estrellanus (Conrad), Pacipecten discus (Conrad), Polymesoda gabbiana (Henderson), Striostrea? bourgeoisii bourgeoisii (Re´mond), and the gastropods Calyptraea (Trochita) filosa (Gabb), Ficus (Trophosycon) kerniana (Cooper), F. (T.) rodeoensis (English), and Oliva simondsi Trask are east of the San Andreas fault. These taxa were living in protected environments (Table 12; Appendix 1, Table A10; Plate 5). There are four northern extraprovincial taxa reported from rocks and warm temperate molluscan assemblages in the 13–8

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines Ma time slice and all are from localities east of the San Andreas fault (Table 12; Appendix 1, Table A10). By way of contrast, there are 62 extratropical or southern extraprovincial taxa among the 8–5 Ma temperate and warm temperate molluscan assemblages from localities east of the San Andreas fault and from palinspastically restored regions west of the San Andreas fault (Table 12; Appendix 1, Table A11). There are seven northern extraprovincial taxa reported from late Miocene–early Pliocene faunal assemblages from California and temperate and warm temperate molluscan assemblages assigned to the 8–5 Ma time slice. These taxa are from localities both east and palinspastically restored regions west of the San Andreas fault (Table 12; Appendix 1, Table A11). Explanations for extraprovincial and thermally anomalous taxa. Several explanations have been proposed for the mixing of tropical, outer tropical, and cool temperate species in warm water faunas. 1. Woodring et al. (1946, p. 101–102) proposed the mechanical mixing of shallow- and deep-water depositional facies. However, the presence of some combination of tropical water, warm water, temperate, and cold water articulated bivalve mollusks in mixed assemblages seems to preclude the mechanism of reworking to account for the thermally anomalous taxa in most of the Neogene assemblages (e.g., Loomis, 1990c; see Kidwell and Bosence, 1991). Modern analogs of the fossil extratropical or southern extraprovincial taxa are known to range into shallow water. 2. Evolutionary changes in molluscan physiology were also proposed as a mechanism to account for thermally anomalous taxa by Woodring and Bramlette (1950). Woodring and Bramlette (1950, p. 99) concluded “The association of northern and southern species throws doubt on the assumption that the present range of identical or closely related species can be used as a close guide in reconstruction of environments. Some of the Pliocene molluscan taxa from Santa Maria Pliocene are no longer living at the latitude of Santa Maria, presumably because their present distribution is controlled by new physiological characters that are not correlated with available new morphological characters.” However, Roy et al. (1995, p. 1071) inferred that the presence of Pleistocene species that today occupy different climatic regions is related to a pattern of “community breakup and species reassortment in response to climate change.” They also stated (Roy et al., 1995, p. 1072) the following (my brackets): For southern forms [referring to Pleistocene species] that expanded their ranges during warming trends, the warmer waters found to the north tend to be at shallow depths. Furthermore, species that range into very shallow waters (intertidal to 1 m) tend to have extensive geographic ranges and physiological tolerances (see Jackson, 1974, Jablonski and Valentine, 1981, Jablonski et al., 1985), and so these are the species preadapted for extensive migrations. In contrast, for northern forms migrating southward during cooling trends, cooler waters can be found in both shallow and deep environments, and cool upwelling patches pro-

vide opportunities for latitudinal range extensions beyond water-type boundaries (Valentine, 1955; Emerson, 1956).

Anomalous distribution patterns of the bivalves Anadara sp. and Dosinia sp. were also discussed by Addicott (1970c), Stanton and Dodd (1970), and Dodd and Stanton (1981). 3. Temporary changes in current patterns or surface watermass properties were proposed by Zinsmeister (1974) and Barry et al. (1995) to account for the presence of thermally anomalous taxa in a molluscan assemblage. Other climate events that could have had a marked affect on the fossil assemblages are the El Ninõ–Southern and La Ninã Oscillation phenomena (Karinen et al., 1985; Philander, 1989). 4. Local paleogeography has been proposed as a mechanism to account for thermally anomalous taxa by DeVries and Wells (1990). However, it is difficult to separate local Neogene geographic controls from Neogene thermal regimes because many of the Neogene molluscan assemblages were living in shallow-water and protected environments. The distribution of the bivalve Mya sp. has been cited as an example of a northern extraprovincial taxon that lived with Neogene temperate or warm temperate marine faunas, and it has been proposed that its presence in the fossil record at lower latitudes indicates regional cooling conditions (Grant and Gale, 1931; Barbat and Galloway, 1934; see also Adegoke, 1966). Dodd and Stanton (1981), however, noted that Mya sp. is geographically restricted today to San Francisco Bay and to bays north of San Francisco Bay, and that the protected-bay and brackish and warmer water environments, not cold water, were factors limiting the distribution of fossil Mya. 5. Global and regional climatic changes have been proposed as the principal causes to account for mixed molluscan assemblages (Roy et al., 1995). Paleotemperatures of Neogene seas periodically declined, fluctuated, and rose, based on the analyses of planktic assemblages (Ingle, 1967; Bandy, 1972; Casey, 1972; Barron, 1973, 1989; Poore, 1981; Barron and Keller, 1983), and regional and global studies of stable isotopes (Savin et al., 1975; Shackleton and Kennett, 1975; Kennett, 1977, 1980, 1986a, 1986b; DePaolo and Ingram, 1985; Vincent and Berger, 1985; Vincent and Killingley, 1985; Capo and DePaolo, 1986; DePaolo, 1986; Miller et al., 1987; Muhs and Kyser, 1987; Woodruff and Savin, 1989, 1991; Compton et al., 1990; DePaolo and Finger, 1991; Wright et al., 1992; Flower and Kennett, 1993a, 1993b; Schoell et al., 1994). 6. Thermally anomalous assemblages have been explained by climatic time averaging (Roy et al., 1996). Climatic time averaging, on a scale of 10 k.y., proposes that ancient marine climates were warmer than the present, which permitted the immigration and introduction of some tropical and outer tropical species into warm temperate biotas. A millennial-scale climatic change allowed some cold water immigrants from northern molluscan provinces to migrate into warm temperate faunas (Roy et al., 1996, p. 461). Points 5 and 6 are considered here to be the principal ex-

planations to account for the presence of extraprovincial molluscan taxa in Neogene fossil assemblages from California, as they were for the presence of extraprovincial taxa in Pleistocene molluscan assemblages (Roy et al., 1995, p. 1073; 1996). In order to account for the marked increase in the numbers of extraprovincial marine molluscan taxa in California Neogene rocks, particularly within the 8–5 Ma time interval, the environmental tolerances of extraprovincial taxa may have changed with time, i.e., tolerances that restricted the geographical ranges of some taxa could have been lowered. However, climatic changes were associated with glaciation and relatively rapidly changing glacial and interglacial events from 17 to 8 Ma. Therefore, more likely than changes in physiological tolerances among many molluscan species during Neogene climatic oscillations, the protected environments in western California provided sanctuary for southern molluscan taxa during the overall Neogene cooling trend and periodic northward incursions of warm water. These sanctuaries for extratropical taxa were eliminated or restricted during the late Neogene, when the embayed coastline of California was largely destroyed between 8 and 5 Ma (Plates 4–8). A present-day analogy is provided by the extratropical taxa that are present in molluscan assemblages along the outer coast of Baja California Sur in relatively small, protected bays. Most of the extraprovincial species (or in some cases genera, when the species is not known or is extinct) are known to range into shallow water, or to range in depth from the intertidal zone into the outer neritic zone (;140 m). The presence of extraprovincial and extratropical taxa in Neogene assemblages, and many of the taxa in mixed warm and cold water fossil assemblages collected from 17–2.5 Ma rocks, can be attributed, for at least some taxa, to a duration of warmth sufficient for all stages of the reproductive cycle. This warmth was in protected, embayed, or shallow-water regions during the overall decline in Neogene SSTs and southern El Ninõ–La Ninã oscillations in the eastern Pacific Ocean. Modern deep-water circulation patterns were established in the eastern Pacific Ocean between 13.5 and 12.5 Ma (Keller and Barron, 1983). The present-day circulation of seawater water in the Pacific Ocean has likely existed since between 3.5 and 3.1 Ma, when the Isthmus of Panama blocked the circulation of equatorial waters between the Atlantic and Pacific Oceans (Berggren and Hollister, 1974; Saito, 1976; Cronin and Dowsett, 1996). Changes in circulation patterns and the paleoclimate oscillations during the Neogene in open ocean and nearshore basins that resulted from global climatic changes during glacial and interglacial intervals would have influenced the distribution of extraprovincial taxa. The oldest recorded El Ninõ–Southern Oscillation phenomenon was reported by Quinn et al. (1978) to have occurred 450 yr ago and by Hughen et al. (1999) to have occurred 124 ka, during the last interglacial period. Such events are known to occur with a 2–10 yr periodicity (Norton et al., 1985). El Ninõ events are known to cause anomalously high SSTs, and

La Ninã events cause anomalously low SSTs. El Ninõ and La Ninã oceanic oscillations or events could account for the presence of some of the extraprovincial taxa in fossil assemblages, particularly those near a provincial or a nearshore regional paleoclimatic boundary. Perhaps the isolated presence of some extratropical taxa in Neogene stratigraphic sequences resulted from these short-term extreme warm and cold water events and incursions of seawater water into some marine paleoclimatic regions, in the manner outlined by Roy et al. (1996) (see preceding explanation 6). The incursions may have been of sufficient duration to allow for the completion of reproductive cycles and the establishment of extraprovincial taxa. The research of Barry et al. (1995) on present-day nearshore organisms tends to support such a hypothesis to account for the presence of some Neogene extratropical taxa in the fossil record. Sea-level oscillations. It is not clear what influence sealevel oscillations (see Haq et al., 1987) have had on restricting the distribution or augmenting the number of late Paleogene and Neogene molluscan assemblages or species in California. The California coastline became more embayed after 17 Ma, and it remained deeply embayed until late Pliocene time (Plates 2–8). The late Paleogene and Neogene benthic molluscan faunas of California lived largely within the intertidal, sublittoral, or littoral bathymetric zones (high tide to 250 m). Unless a strait or seaway was blocked by land as sea level dropped, or barrier bars were built or destroyed, sea-level oscillations probably had little effect on the ability of mollusks to migrate along the coast of California and within the northeastern Pacific Ocean. Molluscan assemblages living in the inner sublittoral and littoral bathymetric zones (high tide to 50 m) could have been affected by warming waters concomitant with shallowing basins of deposition. Throughout the stratigraphic sections of upper Paleogene and Neogene rocks there are successions of coarse- and fine-grained strata associated with molluscan assemblages, and both the sedimentary geology and the faunal assemblages reflect oscillating bathymetric conditions. An interval of major transgression in western California began ca. 25 Ma (e.g., the Vedder Sand). Progradations took place ca. 18 Ma (e.g., the beach and inner shelf deposits of the Olcese Sand), and ca. 13 Ma (e.g., the shallow-water deposits of the Santa Margarita Formation characterized by interbedded sandstone, siltstone, and shale). Regionally, onlapping sequences of sand and shale were deposited ca. 7 Ma (e.g., the Jacalitos and Etchegoin Formations). These rock sequences are locally dominated by lowenergy tide-dominated facies (e.g., interlaminated, fine-grained, sedimentary rocks), high-energy tide-dominated facies (e.g., planar and trough cross-stratified sandstone), low-energy shelf facies, and storm-dominated shelf facies (Loomis, 1990c). Marine basins began to shallow by ca. 5 Ma, as documented by the San Joaquin, Pancho Rico, and Pismo Formations. Tidalflat, or locally trough, environments dominated Pliocene basins in the Santa Maria, Pismo Beach and southern San Joaquin regions. Uplift of the Coast Ranges was coeval with the regression of late Pliocene seas.

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines Regional extinction events Based on the age-range data for taxa listed in Appendix 1 (Table A15), it is possible that two principal regional extinction events influenced the macroinvertebrate taxa that lived in California between 27 and 2.5 Ma (Fig. 28). Perhaps there is a correlation with global extinction events. The major regional extinction events took place between 17 and 13 Ma, and between 5 and 2.5 Ma (or into the Pleistocene), when 234 (;45%) and 257 (;29%) of the species, respectively, during those time intervals became extinct. The Miocene extinction of 234 species seems to correlate with worldwide global cooling associated with the establishment of the East Antarctic ice cap during the 17–13 Ma time slice and between 14.5 and 13 Ma (Table 11). By 13 or 8 Ma, the elimination of the AnaVent gulf, between what is now the Santa Barbara coastline (e.g., Santa Barbara–Ventura) and the San Diego (Santa Ana–San Diego) coastline, could have been responsible for a marked change in seawater circulation along the coast, the opening of the coastline to the cold California Current, the elimination of protected environmental niches, a reduction or an increase in the size of the shelf area at different times, and the extinction of many species (Plates 3C and 4C). Peutch (1993) noted that many tropical fossil taxa (analogs of which live south of lat 358N along the Atlantic coast) became extinct during the deposition of the Calvert Formation (Maryland) at the close of the Langhian Age (see Smith, 1991a, p. 45, for a summary of formational units in the Atlantic coastal region). The boundary between the Langhian (age range of 16.3–14.8 Ma) and the Serravalian stages (age range of 14.8– 11.2 Ma; late Serravalian Age of 12.2 Ma, Hilgen et al., 1997) is at 14.8 Ma (Berggren et al., 1995a). A major floristic change or crisis also took place in western Nevada ca. 15 Ma. This floristic crisis is attributed to a decrease in summer precipitation below 35%–40% of the pre-15 Ma annual total (Axelrod and Schorn, 1994, p. 1). Because of the synchroneity of the age assignments, the early medial Miocene extinction event that took place in the western Atlantic Ocean (Peutch, 1993) and the 15 Ma western Nevada floristic crisis (Axelrod and Schorn, 1994) can be correlated with a global cooling event assigned an age range of 14.5–14.1 Ma (Flower and Kennett, 1993a, 1993b, 1993c). These extinction and global cooling events can also be correlated with the regional extinction of 234 macroinvertebrate species in California between late early and early medial Miocene time, i.e., between 17 and 13 Ma (Table 11). However, a Neogene climatic optimum or warming event also took place from 17 to 15 Ma (Flower and Kennett, 1995). This warming event can also be correlated with the high rate of extinction of both Atlantic and Pacific species living during the 17–13 Ma time slice. Valentine (1968, p. 273) proposed that times of warming should be times with the greatest extinction rates. However, because of the lack of precision in age dating based on mollusks, it is not possible to determine with certainty whether the cooling event between 14.5 and 14.1 Ma (Flower

61

and Kennett, 1993a, 1993b, 1993c) or between 14.8 and 13 Ma (Barron and Ingle, 1999), or the warming event between 17 and 15 Ma was responsible for the 17–13 Ma extinction of ;200 Miocene (17–13 Ma) molluscan taxa that were living in a marine environment along the coast of California. Peutch (1993) suggested that there were late Pliocene (3.5– 2.5 Ma) two-staged, sequential mass-extinction events among fossil mollusks in Florida. Berkman and Prentice (1996) also noted that there was a marked decrease in taxonomic diversity within the Family Pectinidae in Antarctica and that the decrease in diversity can be correlated with 3.2–2.5 Ma mass extinctions in Florida and cooling in both polar regions (Shackleton and Opdyke, 1977). These regional extinction events correlate directly with the 5–2.5 Ma molluscan regional extinctions in California. The debate over the causes of mass and regional extinctions among animals will continue. Prothero (1999) noted the absence of responses by terrestrial mammals to geologically abrupt changes in climate, and Hansen (1987a, 1987b, 1992) concluded that cooling was the primary cause of molluscan extinctions across the Eocene-Oligocene boundary; his conclusion was supported by the work of Gaskell (1991, p. 12) based on Foraminiferida from rocks of the same age and region studied by Hansen (1987a, 1987b). Relative to the regional extinction of the 257 macroinvertebrate taxa from California between the late Pliocene and the Pleistocene, this period of regional extinction seems to correlate with worldwide climatic cooling (not warming), regional glaciation in the Sierra Nevada, the opening of the Bering Strait (3.0 or 5.5 Ma), the closure of the Panama seaway (ca. 3.1 Ma), and possibly to marked changes in the nature of the California shoreline (Table 11; Plates 6B and 8B). The analysis of marine molluscan faunas from southern California indicates that the overall cooling trend that had begun during the Paleogene along the coast of California continued into the interval 5–2.5 Ma (Fig. 27). However, a warming trend occurred in the open ocean of southern California during early Pliocene time (5.2 Ma), based on an analysis of microfossils (Barron, 1973). According to Barron (1973) the SST was between .25 8C during the warmest month and ;17 8C during the coldest month. These warm SSTs could account for the relatively fewer number of molluscan species that became extinct ca. 5 Ma (Fig. 28). However, relatively few Neogene molluscan taxa living along the coast of California became extinct between 27 and 17 Ma when the marine paleoclimate was warm (Figs. 9, 20, 21, and 28). This observation does not seem to support Valentine’s (1968, p. 273) model that times of warming will be times of greatest extinction. In addition, molluscan diversity was also not high during the time interval 27–17 Ma. The marine paleoclimate during the late Paleogene–early Neogene was outer tropical and it was not marked by extremes in temperature; as a result, regional extinction rates were low. Valentine (1968, p. 273) proposed, “times of warming should be times with the greatest extinction rates.” This model does not

seem to be supported by the number of mollusks that became extinct during late Paleogene–early Neogene time and part of late Neogene time in southern California (Fig. 28). The problems associated with sampling, as outlined by Russell and Lindberg (1988), could account for the seemingly low rates of regional extinction between 27 and 17 Ma. However, the apparent extinction rates that occurred among medial and late Neogene molluscan assemblages, when there was greater provinciality and marked oscillations in marine paleoclimate, could be a key element for developing another model to account for extinctions among marine mollusks. With increasing or marked provinciality among molluscan assemblages, and with an increase in the number of thermally anomalous taxa in a faunal assemblage, oscillating times of warming and cooling could be associated with the high rates of extinction; alternatively, times of temperate, mild, or equable marine climates could be associated with the low rates of extinction, relatively fewer faunal provinces, and the presence of relatively few extraprovincial taxa. Kitamura et al. (2000) provided a measure of support for this notion: they noted that when warm water taxa initially migrated into the Sea of Japan during early Pleistocene time, molluscan species lived with cold water species. As the cold water molluscan species became regionally extinct, the warm water species migrated into the niches once occupied by the cold water molluscan taxa. Survivorship of 1206 species, mostly molluscan taxa. Phelps (1985) estimated mean-species longevities of 0.5 m.y. for species living during Early Jurassic time. Hallam (1987) suggested that the longevities of ammonites from Lower Jurassic rocks could have been 0.14 m.y., survivorship among bivalves being 19.0–1.0 m.y. Hoffman and Szubsda-Studencka (1982, p. 126) noted that the mean duration of species longevity is 19.5 m.y. among 93 bivalve molluscan species from Poland. Stanley and Yang (1987, p. 113) observed that longevities of species are ;1–10 m.y. However, Schopf (1984) concluded that the average survivorship of species is 200 k.y., and attributed the longer survivorship proposed by other researchers to (1) a bias toward collecting common long-lived taxa, whereas most taxa he believed are rare; (2) a bias of reporting data to a cumulative stratigraphic unit; and (3) a bias of lumping variation in the polytypic species concept. Given (1) the number of fossil mollusks collected and reported in California over a period of ;100 yr, collections that include rare species; (2) the bracketing of biostratigraphic units by radiometric age dates in California (e.g., Smith, 1991a; Fig. 1 herein), and (3) the reduction in this study from 3254 mostly molluscan taxa to 1206 taxa in order to reduce the chance of a bias when inferring the longevity of a species caused by lumping polytypic species into a long-lived species, it seems that Schopf’s (1984) estimate that the average longevity of species is 200 k.y. is too low. Among the marine macroinvertebrate taxa (principally molluscan taxa) analyzed in this study, the following survived into the Holocene: 4% of the taxa from rocks assigned to the 27–23 Ma time slice, 5% of the taxa from the 23–17 Ma time

slice, 2% from the 17–13 Ma time slice, 15% from the 13–8 Ma time slice, 13% from the 8–5 Ma time slice, and 17% of the taxa from the 5–2.5 Ma time slice. When the species within the total 3294 taxa studied that have an uncertain age or taxonomic assignment are eliminated from consideration, there are 1206 species that provide survivorship information. The average duration of longevity of species in the 6 time slices studied is ;4 m.y.: of the 1206 species considered, 23% have a longevity of two time slices (Fig. 29A); 27% survived from 10 to 5 m.y.; 74%, or 887 species, survived from 10 to 2.5 m.y.; and the average longevity of the 1206 species is ;11.5 m.y. (Fig. 29B). Based on the research of Russell and Lindberg (1988, p. 326), the survivorship estimates presented here could be spurious because species duration and geographic range are interdependent. Both of these factors are only approximations in the present study. Species with restricted geographic ranges can show short geologic durations when no such durations exist. However, the survivorship estimates developed for the taxa studied in this volume seem to suggest that an average longevity of 200 k.y. proposed by other researchers seems to be unlikely. Volcanism, climate, and extinctions. Volcanism west of a magmatic arc trend was common in coastal California throughout late Paleogene and Neogene time; however, volcanic activity increased markedly between 27 and 22 Ma and between 18 and 14 Ma. These two pulses were related to mantle upwelling events associated with subduction of the Vancouver-Farallon and Monterey-Arguello plates or microplates. The second pulse in volcanic activity was coeval with Columbia River basalt volcanism (17–14 Ma) in the Pacific Northwest and volcanism in Nevada (Dickinson, 1997; Dickinson and Wernicke, 1997) (Table 13). East-west extension and transtension in western North America also took place between 16 and 10 Ma (Dickinson and Wernicke, 1997; Wernicke and Snow, 1998), and extension in eastern California was accompanied by volcanism (e.g., volcanic rocks are present in the nonmarine Barstow Formation, Plate 4C). Post-middle Miocene volcanism (from ca. 15 to 0.1 Ma) is related to the northward expansion of a growing slab window, and the northward migration of the Mendocino triple junction (from 13 Ma or earlier to the present) (Dickinson, 1997). The timing of the subduction of the Monterey-Arguello plate, the extrusion of the Columbia River Basalt, and the volcanism in Nevada and eastern California were associated with subaerial and submarine pyroclastic ash flows and ejections. These events are all coeval with the regional extinction of mollusks in California from 17 to 13 Ma, and their correlation is provocative. There are 14 cold and 12 warm paleoclimatic events reported to have taken place in the northeastern Pacific Ocean from medial to late Miocene time (15–5 Ma) (Barron and Keller, 1983). Other warming and cooling events are recorded throughout the geologic record, including ones on a 100 k.y. cycle (Imbrie et al., 1993); and on a submillennial scale at 250 ka (Dansgaard et al., 1993), from 75 to 25 ka (Dorale et al., 1998), from 60 to 15 ka (Labeyrie, 2000, p. 1906), and from

60 ka to present (Cannariato et al., 1999). Behl et al. (2001, p. A-80) reported millennial to Milankovich band climatic cycles that are preserved in the Monterey and Sisquoc Formations (e.g., 8–5 Ma time slice). Thus, global warming or climatic cycles are not only recent phenomena related to anthropogenic forcing or alteration of the Earth’s energy balance by human

activity. Oscillatory climatic trends during the Miocene were likely related to the natural variability of the Earth’s climate system, e.g., changes in North Atlantic thermohaline circulation, which is in part related to such phenomena as changes in eccentricity of the Earth’s orbit and the inclination of Earth’s spin axis (Rial, 1999; Willis et al., 1999), modifications of the

circulation patterns of the oceans owing to plate tectonics (e.g., Pagani et al., 1999a), and shifts in carbon dioxide concentrations (Petit et al., 1999; Wagner et al., 1999). Volcanism also can be added to this list as the radiative effect of increased concentrations of gases between 17 and 13 Ma might have caused the Earth’s temperature to rise; or alternatively, volcanic ash injected into the upper atmosphere could have shielded the Earth from the Sun’s rays and temperatures would have fallen. After Mount Pinatubo in the Philippine Islands erupted in June 1991, clear-sky solar radiation was reduced by as much as 5%, and solar radiation was reduced by an average of 2.7% in the first 10 months after eruption. By September of 1992, the global Northern Hemisphere lower tropospheric temperatures had decreased by 0.5 and 0.7 8C (Dutton and Christy, 1992, p. 2313, 2316). A decrease in temperature of this magnitude, even over an extended period during medial Miocene time, is unlikely to have influenced the regional distribution of Miocene nearshore marine taxa or continental floras. It is conceivable that volcanic events during medial Miocene time were larger and more widespread than the eruption of Mount Pinatubo, perhaps lowering the temperature in the Northern Hemisphere more than 0.7 8C and for a long duration. However, neither the 18–14 Ma volcanic events in California, nor the 17– 14 Ma outpourings of lava of the Columbia River Basalt were accompanied by Plinian eruptions; i.e., they were not accompanied by vast ejections of rhyolitic ash into the stratosphere. Although the Mount Pinatubo volcanic event cooled land surface temperatures in the Northern Hemisphere, a warm water El Ninõ Oscillation event appeared in the tropics at the same time the tropospheric temperature decreased (Dutton and Christy, 1992, p. 2313). Although the volcanic events in the western United States were not Plinian eruptions, the 18–14 Ma volcanic events in Washington, Nevada, and California cannot be completely ruled out as a mechanism to initiate volcanic winters (Tables 11 and 13). Volcanic eruptions produce long-lived stratospheric clouds composed of sulfur-rich aerosols (Rampino and Self, 1984, p. 677). For example, El Chichoń (lat 178N) is estimated to have placed 20 2 1010 kg of H2SO4 into the global stratosphere during a 6-month period after the 1982 eruption (Rampino and Self, 1984). Volcanic sulfur aerosols may cause cooling of the Earth’s surface (Simarski, 1992, p. 1, 11). It was estimated that 6 2 1012 kg of sulfuric acid aerosols may have been ejected into the Earth’s atmosphere during the eruption of the Columbian River Basalt; the aerosols blocked out sunlight (Francis, 1994), and they could have caused global cooling. However, Francis (1994, p. 389) noted some cautions regarding the consideration of sulfuric acid aerosols as a cause of volcanic winters: “Can the stratosphere sustain such dense aerosol loadings? And can basaltic fissure eruptions inject them into the stratosphere anyway?” Thus, although many molluscan taxa became regionally extinct between 17 and 13 Ma, and this period of time is coeval with widespread volcanism in western North America and with

global cooling, it is not proven that volcanism lowered solar radiation and SSTs sufficiently to cause some molluscan taxa to become extinct. There seems to be no correlation between the molluscan regional extinction events, the increased provinciality in California from 27 to 2.5 Ma, and the Cenozoic seawater sulfate S isotope curve, because the curve is relatively flat during this time interval. However, there were marked decreases in marine barite (BaSO4) d34S near the Paleocene-Eocene and EoceneOligocene epoch boundaries (Paytan et al., 1998). Temperate marine paleoclimate From 27 to 23 Ma and from 23 to 17 Ma there were relatively few extraprovincial molluscan taxa. The sharp increase in numbers of extraprovincial taxa in the fossil record in California occurred from 17 to 5 Ma. Extinction was perhaps related to cooling during the late Miocene time, marked by winter minimum SSTs of 10.0 8C and a lower eustatic sea level (Barron, 1973; Keller and Barron, 1983), and the development of a modern California coastline with the near completion of the rotation of the western Transverse Ranges. The paleoclimate from 27 to 17 Ma can be characterized as temperate or equable solely on the basis of the relatively few extraprovincial taxa present in rocks of those ages. The term “equable,” when referring to paleoclimate, can be defined as a narrow difference between summer maximum and winter minimum temperatures, and a reduced annual cycle of temperature (Sloan and Barron, 1990, p. 489; see also Sloan and Barron, 1992; Sloan, 1994). Because continental interiors can have low winter minimum temperatures even during globally warm periods, Sloan and Barron (1990) questioned the utility of the term “equable” when referring to paleoclimate, and they suggested that the term not be used without knowledge of the paleogeography. Marine, not continental, paleoclimates are inferred in this study, and the paleogeography is also inferred; however, the terms “temperate” or “equable” relative to marine paleoclimates need to be defined, and a method for measuring temperateness or equability of marine paleoclimates needs to be developed. Axelrod (1992b, p. 1) defined ideal equable climate as a climate condition with a mean annual temperature of 14.0 8C and a mean annual range of temperature of 0 8C. The mean annual temperature of the Earth is 14.0 8C, a value midway between the thermal limits of tropical and polar climates (Bailey, 1960). Axelrod (1992b) documented a case to show that because the mean temperature of the Earth’s surface has not been much colder or warmer than at present, the mean temperature of 14.0 8C of the Earth has existed since at least Cretaceous time. However, Axelrod (1992b) emphasized that mean annual temperature has no climatic significance. He argued that equability or temperateness should be measured on a scale that is based on a relationship between ET and warmth or duration of growing season; his calculation incorporates both the mean

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines annual temperature (T) and the mean annual range in temperature (AR). Bailey (1960, p. 11) provided the following formulae in order to calculate an index of temperateness (M): M 4 149.4 1 41 log [(AR/2 ` 4)2 ` (T 1 14)2], or M 4 161.7 1 41 log [(warmest month 1 10 8C)2 ` (coldest month 1 18 8C)2]. Using H. Bailey’s (1960) index of temperateness, the lowlands of New Zealand, Tasmania, south China, and the coastal areas of California and Chile are the most temperate terrestrial regions in the world, where M 4 .70. Bailey (1960, Fig. 9) developed a scale of temperateness using his indices of temperateness, i.e., M 4 0–25, extreme; M 4 24–40, intemperate; M 4 40–55, subtemperate; M 4 55–70, temperate; M 4 70– 85, very temperate; M 4 85–90, constant. If SSTs at regional marine climatic boundaries along the west coast of North America (Tables 3 and 4) are used with the index of temperateness formula (second of preceding equations) to calculate temperateness, M 4 45 at 618N (Aleutians), M 4 68 at 488N (Puget Sound, Washington State), M 4 66 at 348N (near Point Conception, California), and M 4 64 at 248N (Cabo San Lucas, Baja California Sur, Mexico). However, there is no clear basis for applying the indices of temperateness for continental climates, developed by Bailey (1960) and advocated by Axelrod (1992b), to the marine realm. In addition, when the formula is used to calculate an index of temperateness for marine climates, the results are not meaningful; i.e., all the M values from widely different latitudes are subtemperate. Axelrod’s (1992b) points are well taken, and temperateness or equability is important when describing marine climates and causes of extinction of organisms (Axelrod, 1967a). An alternative to the indices of temperateness used for continental environments is proposed here for measuring the temperateness of marine paleoclimates. This method of estimating the temperateness of marine climates is founded on models developed by Valentine (1967, 1968), the increase in diversity of Neogene species in California through time, and a present-day latitudinal diversity gradient of marine mollusks. Species diversity. Valentine (1968, p. 273) proposed several models that can be useful when measuring temperateness or equability of ancient marine environments: (1) “world oceans with mild, uniform climates are characterized by low species diversity”; (2) “oceans with cooler polar waters and higher temperature gradients are characterized by high provinciality, high species diversity, and perhaps higher rates of phyletic evolution”; (3) “Climates that fluctuate between cooling and warming trends will act to create species diversity and enrich the marine biota”; and (4) “times of warming should be times of greatest extinction rates.” Increasing species diversity through time. There was an increase in the number of molluscan taxa in California during late Paleogene and Neogene time: 282 taxa are within the 27– 23 Ma time slice, 345 are within the 23–17 Ma time slice, 515 are within the 17–13 Ma time slice, 631 taxa are within the 13– 8 Ma time slice, 578 are within the 8–5 Ma time slice, and 903

65

are within the 5–2.5 Ma time slice (Appendix 1, Tables A7– A12). Valentine (1958) reported 928 species from the Pleistocene deposits of California; 750 species are reported from the Pleistocene Verdean Molluscan Province (named by Valentine, 1961) (Californian Molluscan Province) from southern California (Roy et al., 1995); and 2887 molluscan species, including 1710 bivalved molluscan species, are living today in marine environments shallower than 200 m from Peru to the Arctic Ocean (Roy et al., 1995, p. 1072; Crame, 2000, p. 190). The increasing number of molluscan taxa from 27 Ma to present may reflect the nature of sampling and the preservation of the fossils. However, Valentine (1989, p. 89) stated “Clearly, species-rich accumulations of dead shells, such as are reported in taphonomic studies, have been captured by the fossil record commonly enough and over wide enough a range of shelf environments to form a surprisingly complete record of the easily fossilized fraction of the living fauna.” Acknowledging that there are possible inadequacies of sampling, there was a partial loss of the molluscan fossil record through time owing to dissolution of shell material, and there may be taxonomic problems that could affect the number of extinct species counted; there seems to be a relative increase in the number of molluscan species through Neogene time. K. Roy (2000, written commun.), on the basis of his research, suggested that diversity may have declined since the late Pliocene. An increase, rather than decline, in diversity could be related to increasing molluscan provinciality and to an overall cooling of the marine climate during the Neogene along the coast of California and the eastern Pacific Ocean (Fig. 30). The data herein seem to support a part of one of Valentine’s (1968) models: “oceans with cooler polar waters and higher temperature gradients are characterized by high provinciality, high species diversity, and perhaps higher rates of phyletic evolution.” Present-day latitudinal molluscan diversity gradients. The number of molluscan and endemic molluscan species and the percentage of endemic species in each of the present-day molluscan provinces along the coast of California are shown in Table 5, which illustrates that present-day molluscan assemblages and taxa show a latitudinal faunal diversity gradient associated with a latitudinal thermal gradient. Species diversity decreases toward the north pole, and increases toward tropical regions (see Stehli et al., 1967; Stehli, 1968; Huston, 1994). Tropical regions are considered to be evolutionary centers for new species and genera (Flessa and Jablonski, 1996). The greatest diversity among present-day molluscan species (2887) in the eastern Pacific region is present at low latitudes in the tropics. Stanley et al. (1980) proposed that geographic configuration is more important than latitude in regulating species diversity. An analysis of paleoshoreline maps (Plates 2–5) and the increase in the numbers of marine taxa (Fig. 30; Appendix 1, Tables A7–A10) along the paleocoastline of California seems at first to support this notion; i.e., as the paleogeographic configuration of the California coastline changed from

27 to 13 Ma, and new nearshore environments were provided, new species evolved and occupied those environments. However, from ca. 8 to 2.5 Ma, as the deeply embayed aspect of the Miocene coastline of California became more like the present-day California coastline (i.e., a more linear coastline and one marked by a limited number of bays), species diversity seemingly continued to increase (Appendix 1, Tables A11 and A12; Plates 6 and 8). If species diversity increased, the increase would have been coeval with the regional extinction of molluscan species (Fig. 28). Regional extinction could have been related to the inability of molluscan species to adapt to narrow ecological tolerances and to restricted geographic distribution. These relationships seem to suggest that thermal regime is more important than local geography in shaping molluscan diversity gradients. During the early Paleogene to late Neogene overall cooling trend there was an increase in faunal provinciality; geography played a role in increasing provinciality, but it was not the primary role. During late Paleogene and Neogene time, molluscan diversity and provinciality increased during Cenozoic cooling, and paleoclimate oscillations and paleogeography were responsible for high rates of both extinction and speciation. The temperate or mild, more uniform marine paleoclimate during early Miocene time became less uniform during the late Neogene. With increasing provinciality and thermal diversity, nearshore marine environments became less temperate. Bays and inlets were opened and destroyed during the ;25 m.y. period between 27 and 2.5 Ma. When new environments became available to shallow-water marine organisms, they diversified and occupied the new niches: when niches were destroyed, some of taxa became extinct. Millennial or submillen-

nial changes in water temperatures affect molluscan populations and foster changes in diversity and extinction. Marine climate is clearly the prominent cause for increases in diversity, as well as for local or regional extinctions, but it is not the only cause. Effective temperatures were assigned to Neogene marine molluscan taxa from southern Oregon, California, and northern Mexico (Appendix 1, Tables A7–A12). These temperatures reflect the warmth of the nearshore marine climate region at the northernmost present-day presence of the extant taxa. A taxon can have an ET of 10.31 8C at its northern geographic endpoint, but it can range southward into tropical waters, e.g., the bivalve Megacrenella columbiana (Dall) (geographic range lat 608– 178N). During late Oligocene and early and medial Miocene time there were relatively few molluscan taxa with effective temperatures from 10.17 to 12.0 8C present in molluscan assemblages living in marine outer tropical or warm temperate paleoclimate regions of California. Such taxa increased in number with Cenozoic paleoclimate cooling and increased provinciality (Fig. 31). During the time interval between 27 and 5 Ma, 13%–38% of the taxa in molluscan assemblages that lived in outer tropical paleoclimate regions had effective temperatures of 10.0 or 10.17 to 12.0 8C; however, between 8 and 2.5 Ma, 59%–89% of the taxa in molluscan assemblages living in temperate and cool temperate paleoclimate regions had effective temperatures of 10.17–12.0 8C. The increase in the percentage of mollusks that can live in marine conditions where the ET is 10.17–12.0 8C reflects an increase in molluscan provinciality. I propose that the increase in molluscan provinciality also reflects a reduction in temperateness or equability in the marine climate, and that the percentage of mollusks that can live in marine conditions where the ET is 10.0 or 10.17 to 12.0 8C can be used to define temperateness or equability. If only 13%–38% of the fossil taxa present have an ET between 10.17 and 12.0 8C, this percentage range indicates a very temperate marine climate. If only 39%–49% of the taxa present have an ET between 10.0 or 10.17 and 12.0 8C, this percentage range indicates a temperate marine climate. Terms such as “extreme,” “intemperate,” “subtemperate,” and “constant,” when referring to temperateness of marine climate, seem to have limited utility. A nearshore marine region with a winter minimum temperature of 10.0 8C and a summer maximum temperature of 11.0 8C certainly reflects a nearly constant marine temperature, but seemingly not one that by human standards is “mild.” In this study the term “temperateness” can be substituted for the climate terms “equable” and “mild.” Using the definitions of temperate and very temperate paleoclimate discussed herein, the marine paleoclimate in California was very temperate at low latitudes and temperate at higher latitudes from ca. 27 to 8 Ma. The paleoclimate became less temperate at higher latitudes in California by ca. 8–5 Ma. Paleogeography The early attempts of geologists to reconstruct a part of the Cenozoic paleogeography of California did not consider pal-

OT is outer tropical, WT is warm temperate, T is temperate, and CT is cool temperate. See Table 1 for definitions of paleoclimatic regions. For example, ;20% of taxa in OT paleoclimatic regions during 27–23 Ma time slice have ET between 10.17 and 12.0 8C; percentage remains about same in OT paleoclimatic regions during 23–17 Ma time slice, ;45% of taxa living in WT paleoclimatic regions have ET between 10.17 and 12.0 8C; and by 8–5 Ma time slice there were relatively large percentages of taxa with ET between 10.17 and 12.0 8C living in OT, WT, T, and CT regions as paleoclimatic conditions became less temperate.

inspastic reconstructions (e.g., Loel and Corey, 1932; Axelrod, 1956, Fig. 16). Nevertheless, their attempts to draw Cenozoic paleogeographic maps of California based on the distribution of fossil marine mollusks and land plants were remarkable at the time. Following the seminal research of Hill and Dibblee (1953) on the San Andreas fault, paleogeographers were obliged to restore fault blocks of California to their prefaulted positions in order to make meaningful paleogeologic maps. Commonly the practice was to outline the blocks and shorelines that should be back slipped along faults but not to make the actual palinspastic reconstruction (e.g., Hall, 1960; Addicott, 1967b, 1968). Offset paleoshorelines supported the notion of Hill and Dibblee (1953) that hundreds of kilometers of right slip have occurred along the San Andreas fault (e.g., Clarke and Nilsen, 1973; Stanley, 1986). However, most of the palinspastic maps of California that have been constructed are regional palinspastic maps, not palinspastic maps of the marine basins for the entire state (e.g., Graham, 1976, 1979b; Reid, 1978, 1995; Stuart, 1979a; Graham and Berry, 1979; Graham et al., 1989; Bartow, 1991; Aalto et al., 1995b; Hall et al., 1995; Rumelhart and Ingersoll, 1997; Fritsche, 1998; Ingersoll and Rumelhart, 1999). When the marine basins of western California have been palinspastically restored, the resulting Cenozoic paleoshoreline

maps are generalized or at a very small scale, e.g., Cole and Armentrout (1979) and Nilsen (1987b). It was not until the extraordinary research of Luyendyk and colleagues (e.g., Kamerling and Luyendyk, 1979; Luyendyk et al., 1980) on the paleomagnetic signatures of the Transverse Ranges (Appendix 1, Table A16) that sense could be made of the paleogeography of southern California, and of the paleogeographic ties between the southern San Joaquin Valley, the Santa Maria–Cuyama region, and southern California south of the Tehachapi Mountains. Palinspastic reconstructions of 27– 2.5 Ma paleoshorelines of California are relatively straightforward, with the following exceptions. (1) The base maps for the reconstructions are not plastic; therefore, geometric alignments of restored fault blocks along curved faults are imprecise. (2) Most paleoshorelines depicted in Plates 2–8 are inferred because the original paleoshorelines and the amount of postdepositional erosion are not known or the paleoshoreline is not preserved. (3) Palinspastic restorations of the east San Francisco Bay region are generalized owing to erosion and uncertainties regarding the amounts of right slip along the Calaveras and Hayward fault systems. (4) The restoration of the region of southern California, south of the Transverse Ranges, is the most difficult to reconstruct owing to the generation of new crustal areas that

began to develop ca. 17 Ma and during the transtension that accompanied the clockwise rotation of the Transverse Ranges. In order to provide palinspastic restorations of southwestern California, Crouch and Suppe (1993) and Fritsche (1998) graphically removed several areas of coastal southern California prior to completing their palinspastic restorations. The areas that they removed are a rhombohedral-shaped area between the Palos Verdes fault (PVF, Plate 1B), the East Santa Cruz basin fault zone, Santa Cruz Island (SCIF)–Dume (DumeF)–Santa Monica–Raymond–Hill (SM-R-HF) fault zones (Plate 1B); a triangular area between the Santa Maria River (SMRF)–Foxen Canyon (FCF)–Little Pine (LPF), and Lompoc-Solvang (L-SF) fault zones (Crouch and Suppe, 1993) (Plate 1B); a triangular area between the Whittier (WhitF) and San Gabriel (SGF) faults (Fritsche, 1998) (Plate 1B); and three triangular areas in the western Transverse Ranges (Fritsche, 1998). The granitoid and schist basement notations in Plates 2C and 3C for southern California, refer to areas of metamorphic core complexes. These areas did not exist prior to Miocene extension and volcanism. The metamorphic core complexes of Catalina (Santa Catalina Island, SCI), Orocopia, and Pelona Schists were isostatically uplifted in the Miocene (Crouch and Suppe, 1993) (Plate 2C). They are considered in this study to be beneath the Southern California allochthon (Hall, 1991) (Plates 2C, 3C, and 4C). The importance of noting the presence of the core complexes is to infer the location of the low-angle, solid-barbed fault, which is believed to mark the sole of the southern California allochthon (Hall, 1991). This location is coupled to the location of the Coast Range fault (open barbs). Most palinspastic maps that reconstruct Cenozoic paleogeography do not depict the location of these Mesozoic faults. I have included the inferred and actual location of the two principal types of low-angle Mesozoic faults. The reason for their inclusion is to be able to follow their journey through time as they are translated along elements of the San Andreas fault system. The faults provide a check against the reconstruction of the paleoshorelines. The paleoshorelines may be aligned in a trial restoration; however, if the low-angle faults do not follow a course that eventually leads them to their present-day location, the locations of the paleoshorelines are likely in error or they do not represent the best fit in a reconstruction. The Catalina Schist is a distinctive basement formation that was metamorphosed at estimated paleodepths of ;25–45 km during pre-Late Cretaceous time (minimum age of metamorphism is ca. 110 Ma). The core complex was exposed in early Miocene time. The tectonic denudation, uplift, and unroofing has been interpreted as a multistage process. (1) The Franciscan Complex was subducted and subjected to high-pressure metamorphism. (2) There was underplating and internal extension of the subducted wedge. (3) The Catalina Schist (metamorphosed Franciscan Complex) was uplifted from depths of 25– 45 to 10–15 km by Late Cretaceous time. (4) During latest Oligocene to earliest Miocene time the Great Valley sequence and underlying Catalina Schist were rifted apart 220 5 10 km.

(5) Between 22 and 20 Ma the Catalina Schist was completely unroofed and first exposed to erosion (Crouch and Suppe, 1993, p. 1423). Crouch and Suppe (1993, p. 1430) suggested that dextral simple shear along major transform zones in what is now the offshore Los Angeles basin was associated with the clockwise rotation of the Western Transverse Ranges. Based on the ages of the mid-Miocene volcanic rocks in and around the Los Angeles basin, it is likely that the time of extension or rifting of the region between Ventura and Santa Ana (Plates 2C–4C) inferred by Crouch and Suppe (1993) was ca. 17 Ma rather than the 22–20 Ma that they proposed. If there has been ;220 km of extension, it does not affect the location of the paleoshorelines or paleolatitudes depicted in Plates 2C, 3C, and 4C. Rumelhart and Ingersoll (1997, Fig. 7) used a somewhat different approach to that of Fritsche (1998) in their palinspastic reconstruction of a part of southern California. Relative to the triangular area between the Whittier and San Gabriel faults (WhitF and SGF, Plate 1B), Rumelhart and Ingersoll (1997) created two geometric gaps north and south of the San Gabriel fault in order to accommodate post-12 Ma transpression or shortening. In order to construct Plates 2C, 3C, and 4C, it was necessary to use both Fritsche’s (1998) and Rumelhart and Ingersoll’s (1997) models to reconstruct southern California, i.e., to graphically remove some areas of the base maps underlain by Miocene volcanic rocks, and to extend an area of southern California in order to accommodate transpressional shortening during late Miocene or early Pliocene to Holocene time. Fritsche (1998) removed areas largely underlain by midMiocene volcanic rocks so that in his reconstructions there would be “space” or “room” for latter compression and the extrusion and intrusion of Miocene volcanic rocks in the vicinity of what is now Los Angeles. Rumelhart and Ingersoll (1997), however, removed an arbitrary amount of folded terrane so that they would have space for later compression and the extrusion and intrusion of the mid-Miocene volcanic rocks. In my treatment, it was necessary to do a bit of both these approaches in order to develop the palinspastic reconstruction of southern California. As stated herein, the base maps for the reconstructions are not plastic, and therefore geometric alignments of restored fault blocks along curved faults are imprecise. Thus, substantial imprecision is introduced when this fact is coupled with the inability to precisely remove areas underlain by volcanic rocks and unfold regions. Subsidence of the Los Angeles and Santa Maria basins likely resulted from Monterey plate or microplate capture by the Pacific plate (20–17 Ma, Nicholson et al., 1994; or 18–16 Ma, McCrory et al., 1995), transrotation (ca. 17–12 Ma and later) (Luyendyk and Hornafius, 1987; Ingersoll, 1988; Rumelhart and Ingersoll, 1997), thermal tectonic subsidence (Pitman and Andrews, 1985) (17–6 Ma), post-Oligocene extension or transtension along low-angle detachment faults (20–6 Ma or 12–6 Ma) (Crouch and Suppe, 1993; Rumelhart and Ingersoll,

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines 1997; Ingersoll and Rumelhart, 1999), and transpression and compression (6 Ma to present) (Rumelhart and Ingersoll, 1997; Ingersoll and Rumelhart, 1999). The Pismo and Huasna basins in San Luis Obispo County, north of the Los Angeles basin, are products of thermal subsidence and northwest-southeast extension, probably between 13 and 8 Ma, i.e., subsidence after deposition and emplacement of the Obispo Formation and coeval volcanic rocks (ca. 18–17 Ma) (Hall, 1981a; Heasler and Surdam, 1984). McCrory et al. (1995) inferred that the subsidence of the Santa Maria depositional basin between 16 and 7 Ma was associated with thermal subsidence and with cooling of the underplated oceanic lithosphere (Appendix 1, Tables A3 and A4). Flower and Kennett (1993b, p. 877) suggested “organiccarbon-rich deposition in the Monterey Formation [their age range of 18 to 8 Ma; present-day latitude of ;34.58N, along the Santa Barbara coastline] fostered middle Miocene global cooling through drawdown of atmospheric partial CO2” (my brackets). They also proposed that the deposition of the Monterey Formation coincided with deep-water cooling and growth of the East Antarctic Ice Sheet from 14.5 to 14.1 Ma. In studying the same strata, Schoell et al. (1994) proposed that Miocene surface waters were well mixed between ca. 21 and 17 Ma, but they became stratified between 17 and 16 Ma. Flower and Kennett (1993b) and Schoell et al. (1994) correlated organiccarbon-rich deposition and C35 hopanes that have systematically and chronologically decreasing 13C concentrations, respectively, with global cooling (16.1–14.1 Ma). Both of their correlations seem to be well defined; however, regional tectonism and paleogeography also could have influenced changes in temperature, organic-carbon-rich deposition, and C35 hopanes. Between 27 and 17 Ma the paleolatitude of Santa Barbara, now at ;348N, was near the absolute latitude of 318 or 328N. The Santa Barbara coastline was oriented north-south rather than east-west, and it formed the western shoreline region of the protected AnaVent basin or warm water gulf (a gulf analogous to the Gulf of California but to the west). In addition, a positive landmass existed to the west of the palinspastically restored Santa Barbara region (Plates 2C and 3C). Also note in Plate 2C the proximity of the Colorado River (boundary between California and Arizona) to the AnaVent basin. Howard (2000, p. 1635) noted the “spatial coincidence between Sespe (and other Cenozoic) paleodelta deposits around Los Angeles that contain exotic clasts, and the inferred location of the mouth of the Colorado River” (assuming that it existed during this time). Based on subsurface studies by McCulloh and Beyer (2001), the 27–23 Ma water mass near 338N lat west of the Elsinore fault (ElsF, Plate 2C) should extend to 33.88N lat and near the Elsinore fault. Between 17 and 13 Ma the paleolatitude of the Santa Barbara region was between the absolute latitudes of 328 and 338N and it was no longer a part of a protected-water gulf (Plates 4C and 5C). Owing to the transrotation of the Santa Barbara coastline and transgressive depositional conditions, oceanographic

69

conditions changed markedly along the Santa Barbara coastline between 17 and 13 Ma. Owing to the development of an open and unprotected coastline beginning ca. 17 Ma, the California Current and cold water upwelling would have influenced the physical and biological conditions of deposition of the Monterey Formation. Plate 5C (13–8 Ma time slice) depicts western southern California as a region of transtension when the western Transverse Ranges had not yet arrived at their present-day east-west orientation. The Modelo Formation is assigned to the 13–8 Ma time slice (Appendix 1, Table A4). Rumelhart and Ingersoll (1997) suggested that the south-directed paleocurrent indicators in the Modelo Formation (observed by Sullwold, 1958, 1960) indicate that the Modelo Formation was not rotated, i.e., that rotation of the southern part of the western Transverse Ranges terminated between 12 and 11 Ma. If their interpretation is accepted it does not change the interpretation of paleoclimate for the region or the location of the paleoshorelines depicted in Plate 5C. Liu et al. (1993, p. 799) constructed a highly simplified ocean model for the middle to late Miocene (13–6 Ma) coastal region of central California. Using their model they confirmed that the sea in the Great Valley region of California was separated from the open ocean during late Miocene time. This paleogeographic relationship can be seen in palinspastic reconstructions (Plate 5). A goal of their model was to provide “more sophisticated procedures” for “reconstructing past temperatures” (Liu et al., 1993, p. 809). However, Liu et al. recognized that their model was poorly defined because little is known about the wind-stress field, bathymetry, passageways to the open ocean, and salinities from 13 to 6 Ma or from 13 to 8 Ma (Liu et al., 1993, p. 802). It seems unlikely that all of these parameters can be determined prior to making paleoclimatic models for former marine seas in the future. Palinspastic reconstructions, paleobiologic interpretations of mollusks and planktic microfossils, and isotopic analyses are likely to remain among the most sophisticated procedures for reconstructing paleoshorelines and past nearshore SSTs in California. Ocean models and paleotemperatures that are deduced from skeletal 18O/16O isotope ratios are both dependent on salinity measurements. Without knowledge of seawater chemistry, isotopic paleotemperature estimates can be 10.0–18.0 8C higher than the observed temperatures, and estimated paleotemperatures can be influenced by the influx of freshwater into marine nearshore environments (Klein et al., 1996). If normal seawater salinity is assumed when 18O/16O isotope ratios are calculated from shells of mollusks, resulting paleotemperature analyses can prove to be spurious (see Purton and Brasier, 1997); this would be especially true for fossil mollusks collected from the protected marine paleoenvironments of what is now the Great Valley of California (Plates 2–8). Klein et al. (1996) suggested that the use of skeletal Mg/Ca ratios determined from the calcite in molluscan shells can offset the lack of knowledge of paleosalinities when estimating seawater pa-

leotemperatures. These techniques for estimating marine paleotemperatures using Cenozoic fossils from California have not been widely, or as widely, applied in California as elsewhere, e.g., by Krantz et al. (1987), Jones et al. (1989), Allmon et al. (1992, 1994), Jones and Allmon (1995), and Andreasson and Schmitz (1996). Huber (1981) suggested that the Sierra Nevada was uplifted ca. 10 Ma. Gillespie (1982) proposed 1000 m of crestal uplift that occurred since 3 Ma, as did Small and Anderson (1995), but between 10 and 7 Ma. Wernicke et al. (1996) suggested that this range was initially at 4000–5500 m (ca. 20 Ma) and then it subsided to 2000–3000 m during the late Cenozoic (ca. 10 Ma). Wakabayashi (2000) suggested that crestal uplift of 1440–2150 m began ca. 5 Ma. Chamberlain and Poage (2000) suggested that the Sierra Nevada has been at its present elevation at least since 16 Ma. The different notions for the times of the uplift of the Sierra Nevada, i.e., 16–3 Ma, make it difficult to ascertain the affects of the uplift and glaciation on depocenters that could have taken place from the medial Miocene to the latest Pliocene or Pleistocene. According to some researchers, the late Miocene regression in the San Joaquin basin occurred ca. 10 Ma, and it can be associated with a fall in sea level between 11 and 10 Ma (Haq et al., 1987; Bartow, 1991). Right-lateral shear was also taking place at about this time in the Basin and Range province. The age of alluvial fan deposits along the southeastern margin of the San Joaquin basin is known to be ca. 8 Ma (Bartow, 1991). Because there are no comparable nonmarine deposits known along the northeastern margin of the basin, it has been suggested that uplift of the Sierra Nevada began earlier near the southern end of the range. Neogene nonmarine and marine depocenters in the San Joaquin Valley west of the Sierra Nevada were depicted by Loomis (1990a, Figs. 15C–15E), Bartow (1991, Figs. 9–13), and Reid (1995, Figs. 8–13). Nilsen and Clarke (1987) depicted the Miocene-Pliocene nonmarine depocenters in the Sacramento Valley. Tectonic events, other than the uplift of the Sierra Nevada, affected San Joaquin basin depocenters. The sea in the San Joaquin basin became more restricted during the late Pliocene owing to continued northward translation of Salinia, uplift of regions surrounding the San Joaquin basin, and increased rates of sedimentation. What had a greater effect on the depocenters and the late Miocene–late Pliocene faunas in the San Joaquin basin: the uplift of the Sierra Nevada and associated glaciation or the closing of the seaway into the San Joaquin basin from the west, owing to the uplift of the Coast Ranges? CONCLUSIONS The duration of summer warmth is used to define late Paleogene and Neogene nearshore paleoclimatic regions and temperateness in western California. Based on the very limited

knowledge of gametogenesis and spawning in mollusks, and using (1) season and duration of shell growth and reproduction in present-day mollusks, (2) distribution patterns of living molluscan taxa, and (3) the thermal gradient along the west coast of North America (Tables 1, 3, and 6), the duration of warmth necessary for reproduction is inferred to be an important factor influencing the distribution of many nearshore marine mollusks. Molluscan distribution can also be limited by other factors, such as winter minimum and summer maximum SSTs, availability of nutrients, salinity, and geography; thus, the duration of warmth is only one factor in a regime of environmental factors influencing the distribution of marine molluscan taxa. Defining the northern boundary of nearshore tropical climatic regions or water masses in the Northern Hemisphere by a winter minimum SST of 20.0 8C is flawed because tropical mollusks and other taxonomic groups are known to live in marine environments where SSTs are several degrees colder than 20.0 8C. Characterizing fossil mollusks or large assemblages of mollusks by such factors as availability of nutrients, the salinity of the water in which the mollusks live, and geography are either not possible or not practical. However, for purposes of analyzing or providing an approximation of marine paleoclimate, fossil mollusks can be characterized by the single thermal attribute of summer duration of warmth or effective temperature (ET ). The palinspastic restoration of California for time slices between 27 and 17 Ma restores nearshore outer tropical paleoclimatic regions to latitudes as far north as the absolute latitude of 368N, i.e., near the present-day latitude of Fresno, California (Plates 2 and 3). The present-day northern boundary of the nearshore outer tropical climatic region is between 288 and 278N. During the same 10 m.y. time interval, a nearshore warm temperate paleoclimatic region was probably as far north as 418N. In contrast, the present-day marine nearshore climate or water masses at this latitude, near Eureka, California, is cool temperate. Between 27 and 17 Ma the nearshore marine climate was temperate, i.e., extreme fluctuations in seasonal nearshore marine SSTs were not common. During this time, separate outer tropical and inner tropical paleoclimatic regions were less likely to have existed than a single tropical paleoclimatic region owing to the presence of a weak latitudinal temperature gradient. During the Pleistocene, glacial cooling in the tropics was 1 5 1 8C, although it could have been 2.0–6.0 8C (Broecker, 1996; Wolff et al., 1998); if the latter cooling temperature is correct, then both outer and inner tropical paleoclimatic regions probably were present during the Pleistocene. Late Paleogene and Neogene mollusks from throughout palinspastically restored western California indicate an overall marine climatic cooling trend. The southward latitudinal shift of the marine outer tropical and warm temperate paleoclimatic regions, as defined by the distribution of nearshore marine fossil mollusks, supports the late Cenozoic cooling trend that has been inferred by others based on fossil mollusks, microfossils, and

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines geochemistry (see Table 11; Plates 4–8). The late Cenozoic protected and embayed regions near San Francisco, and in what is now the San Joaquin Valley of California, remained bastions for warm temperate and outer tropical paleomolluscan faunas from 17 to 8 Ma (Plates 4 and 5). Some fossil floras that were living near these protected marine environments reflect a cooler paleoclimate of the more open coastal regions of California (Tables 7 and 8). In addition to the overall Cenozoic cooling trend, the clockwise rotation of the western Transverse Ranges, beginning ca. 17 Ma, influenced the distribution of fossil mollusks, organic-carbon-rich deposits, and stratified surface water by exposing once protected embayed regions to the cold California Current and cold water upwelling. Relict marine molluscan faunas persisted in protected regions (Plate 5B, 13–8 Ma time slice). Warming in the tropics and the concomitant growth of glaciers at high latitudes are associated with an overall Neogene cooling trend in the eastern Pacific Ocean. These conditions strengthened a latitudinal temperature gradient and brought moisture northward from the tropics, which in turn influenced paleofloras that were living relatively near open-coastal environments (Tables 7–10). With a strengthened temperature gradient, greater extremes in SSTs, reduction of temperateness, and an irregular and embayed California coastline, there was an increase in species diversity among mollusks during the Neogene (Figs. 29 and 30). (1) There are 282 (mostly molluscan) taxa known from rocks assigned to the 27–23 Ma time slice; 4% of the species survived into the Holocene. (2) Of 345 taxa from 23–17 Ma rocks, 5% of the species survived into the Holocene. (3) Of 515 taxa from 17–13 Ma rocks, 2% of the species survived into the Holocene. (4) Of 631 taxa from 13–8 Ma rocks, 15% of the species survived into the Holocene. (5) Of 578 taxa from 8–5 Ma rocks, 13% of the species survived into the Holocene. (6) Of 903 taxa from 5–2.5 Ma rocks, 17% of the species survived into the Holocene. (7) There are 928 taxa from Pleistocene deposits. The overall regional extinction rate of mollusks increased in California after 17 Ma. Two prominent intervals of extinction occurred, one between 17 and 13 Ma, and another between 5 and 2.5 Ma (or into Pleistocene time, e.g., 1.8–1.6 Ma) (Fig. 28). These two regional extinction spikes can be correlated with hemispheric cooling, establishment of the East Antarctic ice cap, and other worldwide glacial events (see Table 11). The opening and closing of the Isthmus of Panama, the rotation of the western Transverse Ranges, and the destruction of embayed or gulf regions could also have influenced regional extinction rates among marine mollusks in California. Oscillations in SSTs were perhaps more important than hemispheric cooling events in accounting for high rates of extinction (Table 12). Valentine and Jablonski (1993) and Cannariato et al. (1999) noted that speciation and extinction rates do not increase significantly with extreme environmental instability. However, with increasing or marked provinciality among molluscan assemblages from 27 to

71

2.5 Ma, the highest regional extinction rates correlate with paleoclimatological episodes of warming and cooling. Perhaps there was insufficient time to adapt to new thermal regimes, to cooler temperatures, to a decline in plankton volume, or to migrate. Periodic episodes of regional extinction reduced the size of populations of nearshore mollusks, relatively large numbers of species survived over relatively long periods of time, and new species made their first appearances coeval with periods of regional extinction (Figs. 28 and 29). However, acknowledging the possible inadequacies of sampling, the loss of fossils records, and poorly determined taxonomy, there is a suggestion from the late Paleogene and Neogene molluscan record of California that there was increased speciation or cladogenesis between 27 and 2.5 Ma (Fig. 30). If only anagenesis, i.e., species becoming extinct by gradually evolving into another species, had occurred the number of species would not have increased. Based on the paleogeographic maps for late Paleogene and Neogene time, e.g., Plate 5B, there was isolation of relatively small populations of mollusks at the edge of species ranges. This isolation could have resulted in peripatric speciation, i.e., species formation at the edge of the range of the species. Flower and Kennett (1995) characterized the time from 17 to 15 Ma as the Neogene climatic optimum, with warm, saline, deep water; Flower and Kennett (1993a, 1993b, 1993c) also recognized a subsequent global cooling event between 14.5 and 14.1 Ma. The resolution of the time of regional extinction of mollusks from rocks assigned to the 17–13 Ma time slice is too broad to infer whether a warming event or a cooling event caused so many mollusks to become extinct during this time and many species to make their first appearances. Because water-mass boundaries are more effective barriers for southern species migrating north in response to changing climatic conditions, it is inferred that, after southern species migrated north in times of warming, they were not be able to adapt to the cooler marine conditions. Alternatively, it may not have been possible for large breeding populations of mollusks to move south fast enough in times of cooling before they were eliminated. Extinction rates can be related to the Earth’s history of glaciation; however, glaciation can be related to other factors, such as astronomical cycles, plate tectonics, ocean currents, and atmospheric composition. Hodell and Kennett (1986) recognized worldwide glacial paleoclimatic events at 5.5, 5.3, and 5.1 Ma, and worldwide interglacial paleoclimatic events at 5.2, 5.0, and 4.1 Ma. The cyclical pattern of Neogene glaciation and temperature oscillations, rather than single cooling or warming events, apparently resulted in the high rate of regional extinctions among mollusks between late Pliocene and Pleistocene time, rather than single cooling or warming events (Fig. 28; Table 11). SUMMARY Primarily middle and late Cenozoic, nearshore, marine mollusks from western California (not including taxa from

72

C.A. Hall Jr.

Pleistocene rocks), are assigned to six time slices. These slices are equivalent to molluscan ages, spanning ;25 m.y. from the late Oligocene (27 Ma) to the late Pliocene (2.5 Ma). California is palinspastically restored for each of the time slices by backsliding and back rotating large fault blocks or crustal units. Present-day molluscan provinces are assigned to nearshore water masses or climatic regions, and fossil assemblages are assigned to nearshore paleoclimatic regions within palinspastically restored California. Paleoclimatic regions are based on the distribution of fossils, the northern endpoint of the geographic ranges of the present-day analogs of the fossils, and the effective temperature, duration of summer warmth, or the primary reproductive seasons at the northern endpoint of the geographic ranges of the modern analogs. The ET is a single temperature value that stands for a range of temperature values or a regime. It is used to define marine water masses or climatic and paleoclimatic regions of California; however, it is not the only factor limiting the distribution of poikilothermic marine mollusks. The five nearshore present-day marine climatic regions in the eastern Pacific Ocean, defined on the basis of duration of warmth and effective temperature, are as follows: (1) cool temperate (sea-surface temperatures [SSTs] no cooler than 10.0 8C during the year, and with a range of ET between 10.0 and 12.05 or 12.64 8C); (2) temperate (warmth of at least 13.0 8C for 5.1 months per year, and a range of ET between 17.16 and 19.21 8C); (3) warm temperate (warmth of 15.51 8C for 7.2 months per year, and a range of ET between 14.97 and 17.16 8C); (4) outer tropical (warmth of 17.16 8C for 9.4 months per year, and a range of ET between 17.16 and 19.21 8C); and (5) inner tropical (warmth of at least 18.0 8C for 12 months per year, and range of ET between 19.21 and 23.96 8C). A sixth nearshore cold climatic region is one in which marine SSTs are below 10.0 8C annually. The four late Paleogene and Neogene nearshore paleoclimatic regions in California are: (1) cool temperate (range of mean ET from ,10.98 to 11.86 8C, and 75%–89% of the fauna with ET of between 10.17 and 12.00 8C); (2) temperate (range of mean ET from 11.91 to 12.05 8C, and 49%–68% of fauna with ET between 10.0 and 12.0 8C); (3) warm temperate (range of mean ET from 13.21 to 14.09 8C, and 17%–29% of the fauna with ET between 15.51 and 16.78 8C); (4) outer tropical (range of mean ET from 14.31 to 15.14 8C, and 14%–42% of the fauna with ET between 16.98 and 17.90 8C). A cold paleoclimatic region was not present at any absolute or paleolatitude in California during late Paleogene and Neogene time. Owing to low zoogeographic provinciality during Neogene time, it is not likely that a distinction existed between inner and outer tropical paleoclimatic regions for most of Neogene time. If an inner tropical paleoclimatic region was present south of paleolatitudes and absolute latitudes of California during Neogene time, the seawater in the region would have had a range of ET from 19.21 to .20.0 8C, mean temperature of at least 18.0 8C, and ;30% of the fossil taxa would have had an ET between 18.44 and 27.65 8C.

A long-term global decline in sea-surface and continental temperatures began in Paleocene or Eocene time and continued through late Paleogene and Neogene time. The long-term or overall cooling trend in the eastern Pacific Ocean was associated with an increased latitudinal SST gradient and increased diversity of nearshore marine mollusks. The increase in diversity was marked by an increase in the number of species of marine mollusks and other taxa living along the California paleocoastline. The marine paleoclimate of California became less temperate, i.e., there were greater extremes in temperature and an increase in cool temperate marine molluscan taxa, during the Neogene as the latitudinal marine temperature gradient increased. There were relatively few extraprovincial molluscan taxa, i.e., taxa that migrated across cooler and warmer aberrant paleoclimatic and paleomolluscan provincial boundaries, with ETs of 10.17–12.0 8C, living in the outer tropical and warm temperate paleoclimatic regions during late Oligocene and early and medial Miocene time. Extraprovincial taxa increased in number with cooling paleoclimate and as provinciality increased during Cenozoic time. The marine paleoclimate in California was very temperate at low absolute latitudes, and temperate at higher absolute latitudes from 27 to 8 Ma. At higher absolute latitudes in California the paleoclimate became less temperate from 8 to 5 Ma. The marine paleoclimate (or nearshore water masses) from 27 to 17 Ma in California was outer tropical. The paleoclimate south of the paleolatitudes of California could have been inner tropical or simply tropical; however, fossil molluscan assemblages from south of the absolute latitude of 288N are not included in this study. The seas that occupied much of what is now California during the time interval 27–17 Ma were confined to a large, protected embayed region in central California and to a gulf in southwestern California. A worldwide rise in sea level between 17 and 13 Ma and regional tectonism associated with the 1308–908 clockwise rotation of the western Transverse Ranges during this time interval created new nearshore and embayed environments in California. From late Paleogene to Neogene time, there was an increase in faunal diversity related to strengthened temperature gradients, greater extremes in SSTs, reduction in temperateness, and the development of an embayed California coastline. The latter provided environments for endemic species and refugia for warm water taxa. There was also an increase in the number of molluscan taxa that progressively became extinct: e.g., 81 taxa (29% of the molluscan fauna assigned to the 27–23 Ma time slice) became extinct between 27 and 23 Ma; 71 taxa (21% of the molluscan fauna in the 23–17 Ma time slice) became extinct between 23 and 17 Ma; 234 taxa (45%) became extinct between 17 and 13 Ma; 188 taxa (30%) became extinct between 13 and 8 Ma; 127 taxa (22%) became extinct between 8 and 5 Ma; and 257 taxa (29% of the molluscan fauna in the 5–2.5 Ma time slice) became extinct between 5 and 2.5 Ma, or between 5 and 1.6 Ma. However, if only anagenesis had occurred during

Nearshore marine paleoclimatic regions, increasing provinciality, molluscan extinctions, and paleoshorelines these time intervals, the number of species would not have increased. During episodes of extinction among fossil mollusks living off of California, there was the concurrent appearance of new taxa. Although global cooling took place during medial and late Cenozoic time, particularly from 14.5 to 14.1 Ma, stenothermic mollusks were able to survive and reproduce in the protected warm waters of California from 17 to 13 Ma. The open and unprotected coastal regions of California supported relatively cooler water marine faunas than protected regions. The relatively higher rates of regional extinction from 17 to 13 Ma and 5 to 2.5 Ma could be related to global cooling and changes in ocean circulation patterns. However, it is also likely that a combination of warming and cooling events, perhaps at millennial or submillennial scales, was responsible for a decline of plankton or zooplankton volume and regional extinction of many molluscan species living along the California coast. As warm water mass boundaries periodically moved northward, so did southern stenothermic species. With the onset of a cooling trend, some tropical and warm water taxa either adapted to the cooling conditions or survived as relict faunas in warm, protected environments; or they survived because the seasonal duration of warmth was long enough to complete their reproductive cycle. Some of these warm water taxa became extratropical or extraprovincial. The seasonal duration of warmth needed to complete the reproductive cycles of other southern taxa was no longer of sufficient length and at a marine temperature that would sustain the population. Northern marine species that had occupied a warm temperate water mass or paleoclimatic region during a cooling trend were forced to retreat to the north or into deeper water during the following warming trend. The local and regional reduction of protected nearshore environments along western and southern California during the Neogene (i.e., from 17 Ma to the Pleistocene) exacerbated the episodic SST fluctuations that affected molluscan populations. The palinspastically restored 18–14 Ma volcanic rocks in southwestern California (;500 km in diameter), the 2500 km circumscribed area of the 17–14 Ma Columbia River Basalt, and additional square kilometers of Miocene volcanic rocks in Nevada are coeval with global cooling events and the regional extinction of 234 molluscan taxa in California, and other molluscan taxa in Florida, between 17 and 13 Ma. It is not clear if this period of widespread volcanism, associated with the ejection of sulfuric acid aerosols into the stratosphere, led to global cooling, which in turn could have caused the regional extinction of molluscan taxa. ACKNOWLEDGMENTS This multifaceted research project would not have been possible without the research of others, and there are many persons to whom I am indebted. It is appropriate to list some of the scientists whose research has been absolutely essential to this re-

73

search effort. Perhaps foremost among this group are the taxonomists and biogeographers: W.O. Addicott, F.R. Bernard (deceased), J.W. Durham (deceased), U.S. Grant IV (deceased), L.G. Hertlein (deceased), A.M. Keen (deceased), L.N. Marincovich Jr., J.H. McLean, E.J. Moore, J.T. Smith, W.P. Woodring (deceased), and others listed in Appendix 1 (Tables A7–A12). E.V. Coan and P. Valentich Scott graciously allowed me to use their opus (while in press) on Bivalvia from the eastern Pacific Ocean. The research of all of these scientists forms the foundation for the paleoclimatologic analysis. There are many who contributed essential age-dating information necessary for the present study; however, several researchers deserve special mention: J.A. Barron, J.C. Ingle Jr., G. Keller, R.M. Kleinpell (deceased), R.Z. Poore, D.L. Turner, and D.W. Weaver. Others are listed in the notes in Appendix 1 (Tables A1–A6). T.W. Dibblee Jr., J.G. Vedder, and many others listed in Appendix 1 (Tables A1–A6, A16) provided geologic mapping, which is the cornerstone of any basin analysis. B.P. Luyendyk and colleagues, working with the paleomagnetic signatures of rocks in California, arguably have made the most important contribution to California geology since the pioneering work of M.L. Hill (deceased) and T.W. Dibblee Jr. on the San Andreas fault. Luyendyk’s research on the clockwise rotation of the Transverse Ranges has had a profound influence on the understanding of the tectonic evolution of California and interpretations of its paleogeography. J.C. Crowell and his students, T.W. Dibblee, W.R. Dickinson, S.A. Graham, M.L. Hill (deceased), P.M. Page (deceased), T. Atwater, D.C. Ross, J.M. Mattinson, E.W. James, J.C. Clark, S.H. Clarke, T.H. Nilsen, R.G. Stanley, and many others listed in Appendix 1 (Table A16), made seminal contributions to the understanding of the San Andreas fault system and major faults in western California, without which the construction of the palinspastic maps in this volume would not have been possible. The brilliant research of J.W. Valentine, D. Jablonski, and K. Roy forms the underlying basis for the discussions of the dynamics of Cenozoic molluscan populations and communities. I am indebted to C. Marshal and K. Roy for their reviews, comments, and suggestions regarding many paleobiologic aspects that greatly improved the manuscript. I also thank A.E. Fritsche and R.V. Ingersoll for their thoughtful reviews and suggestions for improvement of the paleoshoreline maps, and the information and data that they provided during the construction of the paleoshoreline maps (Plates 2–8). In addition to their research and suggestions, I relied heavily on the paleogeographic interpretations of W.O. Addicott, J.A. Bartow, A.E. Fritsche, S.A. Graham, S.A. Reid, P.E. Rumelhart, R.G. Stanley, and R.V. Ingersoll. I thank L.L. Holbrook for editorial comments and J. Davidson for helpful discussions regarding the cooling effects of volcanism on climate. I benefited from the review, suggestions, and additional fossil data provided by L.T. Groves and the careful review and editorial comments of Y. Dilek.

Point Arena region Also see the discussion of this region under the 23–17 Ma time slice (Table A2). The Iversen Basalt (23.8 Ma) is placed in the late Zemorrian Age and assigned to the 27–23 Ma time slice. The Skooner Gulch Formation, which overlies the Iversen Basalt, is assigned to a late Zemorrian–early Saucesian Age and to the 27–23 Ma time slice (fossils listed by Addicott, 1967a, p. C4, C6). The Iversen Basalt (Turner, 1970; Dalrymple, 1979) is west of the San Andreas fault. This unit is correlated with the Mindego Basalt in the Santa Cruz Mountains, which is also west of the San Andreas fault but east of the San Gregorio–Hosgri fault. The relationship between the Iversen and Mindego Basalts calls for post-Miocene offsets of 305 km on the San Andreas fault and 115 km on the San Gregorio–San Simeon– Hosgri fault (Graham and Dickinson, 1978a, 1978b; Graham and Peabody, 1981).

Vaqueros Formation (?), Pescadero Point (Hall et al., 1959; Clark and Brabb, 1978; Smith, 1991a, p. 75). Cummings et al. (1962) assigned these same rocks to the Mindego Formation. The Vaqueros Formation (?) also crops out near Anõ Nuevo Point, south of Pescadero Point (Hall et al., 1959; Clark and Brabb, 1978 [late Zemorrian calcareous foraminifers; they noted that the stratigraphically highest faunal assemblage in the rocks is either late Zemorrian or early Saucesian]). Vaqueros Formation, Zayante Creek (Clark et al., 1979, p. 7 [with Saucesian foraminifers, p. 5]); interbedded with basalt flows assigned a potassium-argon age of 23.1 5 0.7 Ma (Turner, 1970).

Vaqueros Formation, San Juan Bautista area (Loel and Corey, 1932, p. 124 [San Juan region]; Allen, 1945, p. 26, 1946, p. 30). The Monterey Formation overlies the Vaqueros Formation and associated volcanic rocks; and the Vaqueros Formation overlies the uppermost Eocene or uppermost Eocene–lowermost Oligocene San Lorenzo Formation (San Juan Bautista Formation of Allen, 1945, 1946) (Refugian Stage) in the San Juan Bautista area, and the stratigraphic section is west of the San Andreas fault. The San Juan Bautista stratigraphic section is correlated with the coeval stratigraphic section in the San Emigdio region (lat 35–348N east of the San Andreas fault) ;300 km to the south on the east side of the San Andreas fault. The Vaqueros Formation of Link and Nilsen (1979, p. 29) is assigned to the lower Zemorrian Stage and the “Unnamed” molluscan stage by Addicott (1979, p. 45). The uppermost sandstone of the upper sandstone member of the Vaqueros in the Santa Lucia Range contains Vertipecten cf. V. alexclarki Addicott. This taxon has an age range of 36.6–32.6 Ma (Smith, 1991a, p. 2); thus, the Vaqueros Formation at the “Indians” in the Santa Lucia Range is not included in the 27–23 Ma time slice. The Vaqueros Formation in the “Indians” region is correlated with the Vaqueros Formation of Cummings et al. (1962) in the Santa Cruz Mountains.

Upper Santos Shale and Agua Sandstone (Addicott, 1973, p. 8, 14). East side of San Joaquin Valley: Vaqueros Formation, Kern River (Loel and Corey, 1932, p. 126–132); Basal Jewett Sand and “grit zone” of Addicott (1970a); Jewett Sand and Freemen Silt (Addicott, 1970a, p. 25–27; Smith, 1991a, p. 82). These units, including the basal Jewett Sand and “grit zone,” include Vertipecten kernensis (Hertlein). Vertipecten kernensis is an index species that Smith (1991a, p. 2) restricted to an age range of between 27.6 and 23 Ma. Based on strontium isotope dates on pectens from the base of the Jewett Sand, Olson (1988, p. 192) assigned the base of the Jewett Sand an age of 23 5 1 Ma, and she stated that “the Zemorrian-Saucesian boundary occurs within the lower part of the Jewett Sand/Freeman Silt system (Bartow and McDougall, 1984).” The Zemorrian–Saucesian boundary is between 22.5 and 21 Ma according to Smith (1991a, p. 3). Smith (1991a, p. 2) placed Olson’s (1988) strontium isotope date of 23 5 1 Ma at the very top of the age range of Vertipecten kernensis (Hertlein). However, Addicott (1965b, p. C103) reported that V. kernensis (4V. nevadanus of Addicott) ranges upward from the basal Jewett Sand into the lower Olcese Sand. In addition, Olson (1988, p. 193) stated that the lower Olcese Sand is “at least older than 18 5 1 Ma.” Therefore the youngest age of V. kernensis must be as young or younger than 23 Ma because it is present above the strontium isotope date of that age, and it is older than 18 Ma. The Jewett Sand is placed within the 27–23 Ma time slice.

Southernmost San Joaquin Valley region, San Emigdio Mountains–Grapevine region Vaqueros Formation (Hoots, 1930, p. 261; Loel and Corey, 1932, p. 95–97; Dickinson and Lowe, 1966, p. 2468).

Smith (1991a, p. 2) restricted the age of V. perrini to the lower “Vaqueros” Stage and to a range in age from 35–26.5 Ma. Smith (1991a, p. 32) assigned the Vaqueros Formation, which crops out in the Morro Creek–Toro Creek area, Morro Bay North quadrangle (the creeks are not in the Cypress Mountain quadrangle as stated in Smith, 1991a, p. 32), to the lower “Vaqueros” Stage because of the presence of V. perrini and “Macrochlamis” magnolia magnolia (Conrad). These same two taxa are also present together in the Green Valley area, Cambria quadrangle (Hall, 1974). In the Green Valley area the Vaqueros Formation locally interfingers with the Lospe Formation of Hall et al. (1979) (which here is assigned to the Simmler Formation, nonmarine rocks east of the San Gregorio–San Simeon–Hosgri fault). The Simmler Formation in the Green Valley area contains clasts from the Morro Rock–Islay Hill Complex and the coeval Cambria Felsite. The Morro Rock–Islay Hill was radiometrically dated by Turner (1970), who assigned radiometric ages of ca. 26–22 Ma to the complex. Thus, the Simmler Formation is younger than 26–22 Ma because it contains clasts of rocks that are that old; and the Vaqueros Formation is younger than 26–22 Ma because it interfingers with the Simmler Formation; it is younger than 26 Ma. As noted in the footnotes for the 23–17 Ma time slice (Table A2), the minimum age of Vertipecten perrini must be younger than the minimum age of 27.6 Ma assigned to V. perrini by Smith (1991a, p. 2) because of the associated stratigraphic relationships and isotopic ages in the southernmost part of the San Joaquin Valley. Based on the biostratigraphic relationships discussed in the text, the correlation of formations in the 23–17 Ma time slice, and the stratigraphic relationships noted in this footnote, V. perrini (Arnold) is assigned to an age range from 35 to 22 Ma. The Vaqueros Formation in western San Luis Obispo County is assigned to the 27–23 Ma time slice, which is equivalent to Smith’s (1991a) middle “Vaqueros” Stage. This age range is in agreement with isotope ages of 26.4–24.4 Ma determined from molluscan shells in the lower part of the Vaqueros Formation collected in the Green Valley, Villa Creek, and the north limb of the Pismo syncline areas (Keller et al., 1995, p. P-6).

TABLE A1. UPPER PALEOGENE TO NEOGENE MARINE FORMATIONS, LATE OLIGOCENE TO EARLY MIOCENE (27–23 Ma) (Continued) † Smith (1991a, p. 30) stated, “Fossils from the central Sierra Madre Range, collected from the Painted Rock Sandstone Member of the Vaqueros Formation as mapped by Fritsche (1969) represent all three subdivisions of the ‘Vaqueros’ Stage.” Fritsche (1969, p. 50) listed several pecten species considered by Smith (1991a, p. 33) to be index species: (1) “Macrochalmis” magnolia (Conrad) (Fritsche, 1969) Lyropecten magnolia (Conrad) from UCLA locality 5564 (LACMIP 25564), his map number 209); (2) Vertipecten kernensis (Hertlein) (Fritsche’s [1969] Vertipecten nevadanus (Conrad) from UCLA locality 5545 [LACMIP 25545], his map number 162b; and UCLA locality 5560 [LACMIP 25560], his map number 204b); (3) L. pretiosus (Hertlein) (Fritsche’s [1969] L. miguelensis (Arnold) also from UCLA locality 5560 or LACMIP 25560); (4) L. miguelensis (Arnold) (Fritsche’s [1969] L. miguelensis (Arnold) from UCLA locality 5548 and 5549 [LACMIP 25548 and 25549], his map numbers 182 and 183 respectively); and (5) Vertipecten bowersi (Arnold) (Fritsche’s [1969] Vertipecten nevadanus (Conrad) also from UCLA localities 5548 and 5549 or LACMIP 25548 and 25549). Smith (1991a, p. 2) restricted “Macrochalmis” magnolia to the lower “Vaqueros” Stage, with an age range of 32.6–27.6 Ma or to 22 Ma in her analysis. Smith (1991a) restricted V. kernensis (27–23 Ma) and L. pretiosus (27.6–21.5 Ma) to the middle “Vaqueros” Stage. Smith (1991a) assigned L. miguelensis (23–18.5 Ma) and V. bowersi (23–19 Ma) to the upper “Vaqueros” Stage. Thus, based on these ranges, the Painted Rock Sandstone Member of the Vaqueros Formation has an age range from 32.6 to 18.5 Ma, and it is assigned to three time slices in Smith’s (1991a) analysis (all numerical ages are those of Smith, 1991a, p. 2). An alternative age assignment for the Painted Rock Sandstone Member of the Vaqueros Formation is used herein. The Soda Lake Shale Member of the Vaqueros Formation was assigned a late Zemorrian Age by Pierce in Dibblee (1973a, p. 18). The late Zemorrian has an age range of 27–21 Ma (Poore, 1980; Poore et al., 1981). Locally, the Soda Lake Shale Member grades laterally into the Painted Rock Sandstone Member, or locally it is beneath the Painted Rock Sandstone Member in the region mapped by Fritsche (1969). In addition to the species of pectens collected by Fritsche (1969) at the localities cited by Smith (1991a, p. 33), Fritsche (1969, p. 50) collected L. miguelensis (Arnold) (Smith’s, 1991a, age of 23–18.5 Ma) and V. kernensis (Hertlein) (27–23 Ma according to Smith, 1991a, p. 2; but 27–17 Ma in this study [see discussion of this taxon under the 23–17 Ma time slice, Table A2]) together from four other and different fossil localities than those cited in the previous paragraph (i.e., at Fritsche’s [1969] map numbers 158, 159a, 180, and 204a). Fritsche (1969) also collected L. miguelensis (Smith’s [1991a] age of 23–18.5 Ma) and “M.” magnolia (Smith’s [1991a] age of 32.6–27.6 Ma or 32.6–22 Ma; but 32–17 Ma in this study because this species is present in rocks that have a radiometric age of ca. 17 Ma) together from another single locality (Fritsche’s [1969] map number 159b). Thus, end members of this series of index species, representing the three substages of Smith’s (1991a) “Vaqueros” Stage, are present together. The age ranges of these three index pecten species overlap: (1) “M.” magnolia, 32–17 Ma with (2) V. kernensis, 27–17 Ma; and (2) V. kernensis with (3) L. pretiosus, 27–21.5 Ma. Vertipecten kernensis (27–23 Ma, Smith, 1991a; and 27–17 Ma herein) is present together with L. miguelensis (23–18.5 Ma, Smith, 1991a). Based on the presence of benthic foraminifers in the Painted Rock Sandstone Member, the age of the member is 27–21 Ma, or where it is above the Soda Lake Shale Member of the Vaqueros Formation, it could be within that age range or it could be younger than the underlying shale. Based on the overlapping age ranges of three groups of index species of pecten, the age of the Painted Rock Sandstone Member is assigned an age range of 27–21.5 Ma and to the 27–23 Ma time slice. The oldest age of L. miguelensis is here extended downward from 23–27 Ma, and assigned an overall range of 27–17 Ma. Because V. bowersi (Arnold) is present at the same localities as Lyropecten miguelensis, and Lyropecten miguelensis is present with V. kernensis, the oldest age of V. bowersi is extended downward from 23–27 Ma; because V. bowersi is present with taxa restricted to the 17–13 Ma time slice, its youngest age is extended upward from 18–16 Ma, with the overall range being 27–16 Ma. The Soda Lake Shale Member of the Vaqueros Formation is assigned to the 27–23 Ma time slice because locally it is interbedded with the Painted Rock Sandstone Member. The Soda Lake Sandstone Member of the Vaqueros Formation (Hill et al., 1958, p. 2984) was renamed the Quail Canyon Sandstone Member of the Vaqueros Formation by Dibblee (1973a, p. 17). The Quail Canyon Member is beneath the Soda Lake Shale Member and it is assigned an age range of 32– 27 Ma.

Point Arena region Gallaway Formation (Addicott, 1967a, p. C4, C6; Phillips et al., 1976). Phillips et al. (1976) assigned the top of the Gallaway Formation to an early Saucesian Age; however, Miller (1981, 1987), also using microfossils, assigned the Gallaway Formation to the lower CN3 zone, equivalent to a late Saucesian–Relizian Age ca. 18–16 Ma). The Gallaway Formation is stratigraphically beneath the Point Arena Formation, which has been assigned ages of ca. 16.5–11.5 Ma, or latest early Miocene–medial Miocene Age (see Loomis and Ingle, 1994); thus, the Gallaway Formation is, or is in part, older than the overlying Point Arena Formation, i.e. it is older than 16 Ma and the Gallaway Formation is assigned to the 23–17 Ma time slice. The Skooner Gulch glauconitic sandstone is below the Gallaway Formation, and it has been assigned a radiometric age of 15.6 Ma (Turner, 1970). However, because the Skooner Gulch Formation is beneath rocks that have been dated as 16.5 Ma, Turner’s (1970) radiometric-age assignment of 15.6 Ma for the Skooner Gulch Formation is considered to be spurious. Addicott (1967a) assigned a Zemorrian Age to the Skooner Gulch Formation, and late Zemorrian–early Saucesian Ages (ca. 27–22 Ma) to the Gallaway Formation. The Skooner Gulch Formation is above the Iversen Basalt, which has been assigned a 23.8 Ma radiometric age (COSUNA, 1984). The Iversen Basalt (23.8 Ma) is placed in the late Zemorrian Age, and it is assigned to the 27–23 Ma time slice. The overlying Skooner Gulch Formation is assigned a late Zemorrian–early Saucesian Age and also to the 27–23 Ma time slice, which is in agreement with the age determined by Phillips et al. (1976). The overlying Gallaway Formation is assigned a latest Zemorrian, or an earliest Saucesian–early Relizian Age, and, as noted above, to the 23–17 Ma time slice.

Santa Maria–Cuyama–Los Angeles region Tranquillon Formation (or Tranquillon volcanic rocks, 17 Ma). Dibblee (1950, p. 34) noted the presence of late Saucesian foraminifers in the underlying Rincon Shale, and he also listed five molluscan taxa from the Tranquillon Formation. Among the five taxa are the pectens “Marochlamis” magnolia magnolia (Conrad) and Amusium lompocensis (Arnold) (23–13 Ma). Smith (1991a, p. 73) noted the presence of the “Macrochlamis” from what must be the same locality as that reported by Dibblee (1950), i.e., south of the Santa Ynez River near Solvang. Smith (1991a, p. 2) assigned an age range to “M.” magnolia of 32.6–27.6 Ma, and noted the possibility that the species could range upward to 22 Ma because the taxon was reported by Vedder (in Smith, 1991a) to be present with Saucesian foraminifers (Smith, 1991a, p. 2, 3, 73). “Macrochlamis” magnolia has an uppermost age of 22 Ma, or younger, because it is reported with Saucesian foraminifers (Smith, 1991a), and the pecten is present above late Saucesian foraminifers (Dibblee, 1950). The taxon is present within the Tranquillon Formation, which has been assigned a radiometric age of 17 Ma (Turner, 1970). “Macrochlamis” magnolia is also present in the Obispo Formation (Hall and Corbato´, 1967, Plate 1, locality 4583) [west of the West Huasna fault and east of Arroyo Grande]). The Obispo Formation near that fossil locality has been assigned an age range of 16.5–15.3 Ma (Turner, 1970). “Marochlamis” magnolia magnolia (Conrad) in this study is assigned an age range of 32–17 Ma. The following stratigraphic units are also included in the 23–17 Ma time slice: Rincon Shale (Saucesian), lower Branch Canyon Formation, and the Saltos Shale (in part) of the Member Monterey Formation, the latter locally intertongues with the lower Branch Canyon Formation (Saucesian and Relizian foraminifers) (Fritsche, 1969, p. 177, 1993, p. 6; Addicott et al., 1978a, p. 55; Obradovich and Naeser, 1981 [21.5–,14 Ma, or 21.5–17.4 Ma]).

The Topanga Formation has an age range from 23 to ca. 13 Ma, i.e., latest Zemorrian, Saucesian, Relizian, and early Luisian Ages in terms of benthic foraminiferal ages. In the Santa Monica Mountains the Topanga Formation in the eastern Santa Monica Mountains is included in the 17–13 Ma time slice. In the western Santa Monica Mountains the Topanga Formation is included in the 23–17 Ma time slice. In the Santa Ana Mountains (see following and 17–13 Ma time slice) the Topanga Formation is included in the 23–17 Ma and 17–13 Ma time slices. “Unnamed” sandstone and Topanga Canyon Formation of western Santa Monica Mountains (Fritsche, 1993, p. 6).

Los Angeles–southern California region San Onofre Breccia (Bereskin and Edwards, 1969, p. 77–78, Saucesian and Relizian Ages, Santa Cruz Island; COSUNA, 1984). Stuart (1979b, p. 26) reviewed the age assignments (Saucesian, Relizian, and Luisian Ages) of the San Onofre Breccia. The formation is older in the Channel Islands and Malibu areas, and is younger, i.e., Luisian Age, in the Los Angeles basin (Blake, 1991). The Catalina Schist clasts in the San Onofre Breccia suggest that the schist was elevated above sea level during deposition of the breccia; however, this is not depicted on Plate 3C. Temblor Formation of Santa Cruz Island (Bremner, 1932, p. 20–21). Upper Rincon Formation (Saucesian Age), Santa Rosa and San Miguel islands (Avila and Weaver, 1969, p. 65; Weaver and Doerner, 1969, p. 80). Topanga Formation and horizon in the Santa Ana Mountains (Loel and Corey, 1932, p. 167–174; Schoellhamer et al., 1981, p. D94–D96). The Topanga Formation in the Santa Ana Mountains region is assigned to the 17–13 Ma time slice (see Table A3 for basis of assignment) and to the 23–17 Ma time slice because of the overlapping age ranges of the following pectens that are present together in these rocks in the Santa Ana Mountains: Amusium lompocensis (23–13 Ma), Amussiopecten vanvlecki (27–13 Ma), Chlamys hertleini (27–13 Ma), Lyropecten crassicardo (18–8 Ma), L. miguelensis (27–17 Ma), Pacipecten andersoni andersoni (23–13 Ma), Vertipecten bowersi (according to Smith, 1991a, p. 2, 23–19.5 Ma or 18 Ma; but 27–16 Ma herein), V. kernensis (27–17 Ma), and V. perrini (35–22 Ma).

In this study, the lower and middle Olcese Sand are included in the 23–17 Ma time slice, and the upper Olcese Sand is included in the 17–13 Ma time slice.

The Obispo tuff is assigned in part to a Relizian Age, with radiometric ages of 16.5, 16.3, 15.9, 15.4, and 15.3 Ma (Turner, 1970).

Point Arena region Point Arena and Monterey Formation* (ca. 16.5–11.5 Ma; CN3–CN5 calcareous nannoplanktic zones) (Loomis and Ingle, 1994). Loomis and Ingle (1994) assigned a “latest early Miocene to middle Miocene age” to the Point Arena Formation (also see Barron, 1986b). Miller (1981, 1987) assigned the Gallaway Formation to the CN3 zone and correlated it with the Relizian Stage, and a radiometric age of ca. 16.5 Ma (Loomis and Ingle, 1994). The Gallaway Formation is stratigraphically below the Point Arena Formation, thus it cannot be everywhere the same age as the Point Arena Formation, and it is likely older than the Point Arena Formation. COSUNA (1984) placed the Gallaway Formation between 23.1 and ca. 20 Ma. The Gallaway Formation is assigned to the 23–17 Ma time slice in this study. Monterey Formation at Point Reyes (Weaver, 1949) is assigned to the 17–13 Ma time slice.

Santa Maria–Cuyama–Los Angeles region Whiterock Bluff Shale Member of Monterey Formation (La Panza Range) (Dibblee, 1973a, 1973b) (member considered to be of early Mohnian Age by Poore et al. (1981, p. 17), but considered to be 15–14 Ma by Obradovich and Naeser (1981); the latter age assignment is followed in this volume. Lower and middle submembers of upper member of Branch Canyon Formation of Fritsche (1969). Branch Canyon Formation (Thomas et al., 1988). Undifferentiated Monterey Formation of Fritsche (1969); Monterey Formation (Thomas et al., 1988). Lower “Briones” Stage (Eaton et al., 1941). Saltos Shale: the Saltos Shale in this region was assigned a Saucesian-Relizian Age by Addicott et al. (1978b, p. 55); they stated that the member is assigned to the “late early Miocene to middle Miocene ‘Temblor’ Stage (sic) and equivalent to Barker’s Ranch fauna of the southern San Joaquin Valley” (emphasis added). The Barker’s Ranch fauna, east of the San Andreas fault, is present in the upper Olcese Sand and this unit interfingers with the Round Mountain Silt. The Olcese and Round Mountain formations, east of the San Andreas fault, were assigned a middle Miocene age by Addicott (1970a). Addicott (1970a, p. 35) noted that Kleinpell (1938) and Kleinpell and Weaver (1963) assigned the upper part of the Olcese Sand, i.e., the Temblor B zone sand of Barker’s Ranch, to the upper part of the Saucesian Stage; however, Weaver et al. (1944) and Church and Krammes (in Church et al., 1957) assigned the Round Mountain Silt to Relizian and Luisian Ages. Foraminifers from the lower part of the Olcese Sand are assigned a late Saucesian Age (Addicott, 1970a, p. 34). Confusion about the age of the Saltos Shale is also introduced by an age assignment of a Relizian-Luisian Age (i.e., ca. 18–14 Ma) by Poore et al. (1981), but Saucesian, Relizian, and Luisian Ages (21.5 to ,14 Ma and 21.5–17.4 Ma) by Obradovich and Naeser (1981). The Saltos Shale is assigned to the 23–17 Ma time slice in this study. Correlation of the Salto Shale with the Olcese Sand is further confused by an age assignment of Vertipecten fucanus (Dall), which is present in the Olcese Sand. Smith (1991a, p. 81) noted that V. fucanus is reported from the upper part of the Olcese Sand, but she stated “the possibility remains that the strata in which V. fucanus is found is (sic) part of the undivided Freeman Silt–Jewett Sand unit” (i.e., stratigraphically below the Olcese Sand). Thus, based on Smith’s (1991a) analysis, V. fucanus is either not present in the upper part of the Olcese Sand, or the upper part of the Olcese Sand should be assigned an early Miocene age, and to the upper “Vaqueros” Stage, but not to a medial Miocene age or to the “Temblor” Stage. For more discussion of the age assignment of associated taxa and correlated units, see lat ;34–338N below.

Santa Maria–Cuyama–Los Angeles region (continued) Temblor Formation (Page et al., 1951; Repenning and Vedder, 1961). Point Sal Formation (in part) (Stanley et al., 1996 [Foraminiferida]). Caliente Formation (nonmarine) (in part 15.6 Ma, Barstovian Age; Hemingfordian Age (Kelley and Lander, 1988). Monterey Formation, Santa Barbara area (Issacs, 1983). Topanga Formation (Kew, 1924; Hoots, 1931; Susuki, 1951; Page et al., 1951; Groves, 1994). Susuki’s (1951) faunal list includes both Lyropecten crassicardo (Conrad), which Smith (1991a, p. 2) assigned a 17–10 Ma age range (but it is assigned to an age range of 18–8 Ma in this study), and V. bowersi (Arnold) (4Susuki’s Pecten nevadanus), which Smith (1991a, p. 2) restricted to ages of between 23 and 19.5 Ma or 23 and 18 Ma from the same localities and near the top of Susuki’s (1951) stratigraphic section, e.g., his localities 3 and 55. Thus, the age range of V. bowersi must be extended upward from the range suggested by Smith (1991a) because it is present with L. crassicardo. The range of V. bowersi is considered here to be 27–16 Ma. The Topanga Formation from the eastern Santa Monica Mountains is assigned to the 17–13 Ma time slice.

Los Angeles–Santa Ana region Monterey Formation (Conrad and Ehlig, 1983); Altamira Shale (in part) (Obradovich and Naeser, 1981); lower and middle Altamira Shale submembers Monterey Formation (Woodring et al., 1946); and Monterey Shale (assigned to the Luisian Stage). Topanga Formation: Schoellhamer et al. (1981, p. D39) stated, “The dominant rock is sandstone [referring to the Topanga Formation in the Santa Ana Mountains], and the molluscan and foraminiferal faunas are so similar that correlation between the areas [referring to the Topanga Formation in the Santa Ana Mountains, the San Joaquin Hills, and the Santa Monica Mountains] is well established” (my brackets). Smith (1960, p. 466 and Table 3) assigned the foraminifers from the Topanga Formation in the Santa Ana Mountains to a questionable Relizian Age. This age assignment is supported by the 13.7 or 11 Ma radiometric age of the overlying El Modeno Andesite. These volcanic rocks are in turn overlain by a claystone bed that contains foraminifers of Luisian Age (Smith, 1960, p. 466, Table 3). Schoellhamer et al. (1981, p. D37) considered the Topanga Formation of the Santa Ana Mountains to be of “middle Miocene age,” based on “the Turritella ocoyana fauna.” However, the same authors reported V. nevadanus (Conrad) from several localities in the Topanga Formation of the Santa Ana region. Smith (1991a), in her monograph on pectens, assigned some specimens of V. nevadanus (Conrad) to V. kernensis (Hertlein) and other specimens of V. nevadanus to V. fucanus or V. bowersi (Smith, 1991a, p. 82, 84). Smith (1991a) considered V. kernensis to be an index species of the middle “Vaqueros” Stage (late Oligocene or 27.6–23 Ma in Smith’s chronology). Smith (1991a, p. 2) assigned an age range of 23–19.5 Ma to V. fucanus. Smith (1991a, p. 2) assigned an age range of 23–19.5 Ma, or to 18 Ma, to V. bowersi. Thus, based on the reported presence of V. nevadanus from the Topanga Formation of the Santa Ana Mountains, the age of the Topanga Formation there must be of Relizian Age and older, based on any of the age ranges of the three species of Vertipecten, and Smith’s (1991a) age assignments. Schoellhamer et al. (1981, p. D93–D95) reported Leptopecten andersoni (Arnold) [4 Pacipecten andersoni andersoni (Arnold)] from the Topanga Formation of the Santa Ana Mountains. Addicott (in Moore, 1984, p. B45) noted that this species is restricted to the “Temblor” Stage or “is of latest early Miocene and middle Miocene age”; and Moore (1984, p. B46) stated: “This subspecies (referring to P. andersoni andersoni) does not occur in the Vaqueros Formation, and citations to that effect are in error.” The “latest early Miocene” would be ca. 17 Ma and “middle Miocene” is from 16.5 to 10.5 Ma, according to Smith (1991a, p. 2). Thus, if V. kernensis is present in the Topanga Formation of the Santa Ana Mountains, the age range assignment of V. kernensis (V. nevadanus of authors) is in conflict with the age assignment of P. andersoni andersoni, i.e., V. kernensis is either present in younger strata than Smith (1991a) reported, P. andersoni andersoni is older than W.O. Addicott (in Moore, 1984) considered it to be, or the pecten has been misidentified as V. kernensis. Schoellhamer et al. (1981, p. D93–D95) reported the following early to medial Miocene species from the Topanga Formation of the Santa Ana Mountains: Bruclarkia barkeriana (Cooper), Conus (Chelyconus) owenianus Anderson, Trophon (Austrotrophon) kernensis Anderson, and Turritella ocoyana Conrad. The authors also reported a medial to late Miocene species, i.e., Cancellaria (Pyruclia) lickana Anderson and Martin. Addicott (1970a, p. 34) noted that the joint presence of these species in the upper Olcese Sand and Round Mountain Silt provide evidence for a medial Miocene age for his units. The same argument can be applied to the Topanga Formation of the Santa Ana Mountains, i.e., to at least part of the Topanga Formation in the Santa Ana Mountains. Schoellhamer et al. (1981, p. D93–D95) reported Nassarius (Catilon?) antiselli (Anderson and Martin) from the Topanga Formation of the Santa Ana Mountains. Addicott (1965a, p. B13) assigned a medial Miocene age, 16.5–10.5 Ma in Smith’s (1991a, p. 2) chronology, to this index species. Schoellhamer et al. (1981, p. D94–D95) reported Lyropecten crassicardo (Conrad) from the Topanga Formation of the Santa Ana Mountains. Smith (1991a, p. 55) restricted L. crassicardo to the “Middle ‘Temblor’ to upper ‘Margarita’ Stages” (ca. 16–10 Ma). Schoellhamer et al. (1981, p. D95) reported Antillophos posunculensis (Anderson and Martin) (considered to be Phos [Antillophos] posunculensis [Anderson and Martin] in this study) from the Topanga Formation of the Santa Ana Mountains. Addicott (1970a, p. 31, 97) reported this species from the Round Mountain Silt and the upper part of the Olcese Sand. He regarded these rock units as late “Temblor” in age (ca. 19–12 Ma).

Los Angeles–Santa Ana region (continued) Schoellhamer et al. (1981, p. D95) reported Cancellaria (Euclia) condoni Anderson from the Topanga Formation of the Santa Ana region. Addicott (1970a, p. 106) noted that “only three cancellarids are reported from strata assigned to the lower Miocene ‘Vaqueros Stage,’ namely, C. condoni Anderson (Repenning and Vedder, 1961); C. dalliana Anderson (Loel and Corey, 1932); and C. galei n.sp.” However, Addicott (1970a, p. 110) assigned C. dalliana to the “Middle Miocene” and noted that his localities are all from the upper part of the Olcese Sand, i.e., upper “Temblor” Age Santa Ana Mountains. Addicott (1970a, p. 107) reported this species from the upper part of the Olcese Sand. If the specimens identified as Pecten nevadanus or V. nevadanus from the Santa Monica and Santa Ana mountains, respectively by Susuki (1951) and Schoellhamer et al. (1981) are V. bowersi (using Smith’s [1991a] classification of V. nevadanus of authors), and using Smith’s (1991a, p. 2) age assignment of V. bowersi, the age of the Topanga Formation is ca. 23 to 19.5 Ma. However, Vedder et al. (1973) reported V. nevadanus (4V. bowersi, fide Smith [1991a, p. 79]) from rocks of earliest Relizian Age, or ca. 15.3 Ma in Smith’s (1991a, p. 3) chronology. In conclusion, the age of the Topanga Formation in the Santa Monica Mountains is assigned to the 17–13 Ma time slice. The age of the Topanga Formation in the Santa Ana region is assigned to both the 17–13 Ma and the 23–17 Ma time slices. Topanga Formation (English, 1926).

Perhaps the rocks at Round Valley in the Covelo district, Mendocino County, are part of the Bear River beds (ca. 27–6 Ma) Aalto et al.

The list of fossils from the Vaqueros Sandstone (middle Miocene age) in Arnold (1906, p. 19) includes fossils from both the Vaqueros and Temblor Formations, from east and west of the San Andreas fault, and from different but unspecified latitudes; therefore the list is not useful for correlations and biostratigraphy in this study.

Hollister–Panoche Pass–central San Joaquin Valley–Coalinga region Temblor beds (Anderson, 1908) [these rocks probably include fossils that should be placed within the 23–17 Ma time slice; however there is insufficient stratigraphic and biostratigraphic control to separate the rocks mapped by Anderson (1908) into both the 23–17 Ma and 17–13 Ma time slices]. Vaqueros Formation (4Temblor Formation) (Arnold, 1909). Temblor Formation (Atwill, 1935; Woodring et al., 1940; Zimmerman, 1944; Axelrod, 1939, 1985). Big Blue Member of Temblor Formation or Big Blue Formation (Kleinpell, 1938, p. 124; Adegoke, 1967, 1969, p. 41). Upper sandstone member Temblor Formation (Wilson, 1943). The distribution of the Temblor Formation in the San Joaquin Valley is shown by Bent (1988, Figs. 3 and 4, and elsewhere in that volume). The part of this formation that is medial Miocene in age (Relizian and Luisian) is included in the 17–13 Ma time slice. Olson (1985, p. 121–177) provided a list of fossils that are from the Temblor Formation in the San Joaquin Valley at this latitude; however, because of the long duration of the deposition of the Temblor Formation, which was well illustrated by Graham (1985, Fig. 2), Olson’s (1985) list has limited biostratigraphic utility.

Reef Ridge–Devils Den–Wheeler Ridge–southern and southeastern San Joaquin Valley region Temblor Formation or horizon (Anderson, 1905, 1911; Arnold, 1906, 1909; Arnold and Johnson, 1910; Martin, 1916; Woodring et al., 1940; Wilson, 1943; Keen, 1943; Stewart, 1946; Dickinson, 1963; Addicott, 1965b, 1970a; Adegoke, 1969). Buttonbed Sandstone Member of the Temblor Formation (Dibblee, 1973a). Escudo Formation of some (e.g., Dibblee, 1973a, p. 24; see also Heikkila and MacLeod, 1951). Addicott (1972, p. 11–13) assigned the Buttonbed Sandstone Member to his lower “Temblor Stage,” which would likely correlate with the 23–17 Ma time slice of this study. However, the presence of Lyropecten crassicardo (Conrad) in the Buttonbed Sandstone (Addicott, 1972, p. 11) suggests that the Buttonbed Sandstone should be assigned to the 17–13 Ma time slice because Lyropecten crassicardo has an age range of 18 to 10 Ma (Smith. 1991a, p. 2), or an age range of 18–8 Ma based on this study. Gould and Devilwater Shale Members of Monterey Formation (Addicott, 1972, p. 11; Dibblee, 1973b). Upper part of the Olcese Sand and the Round Mountain Silt (Temblor Formation of authors, includes upper part of the Olcese Sand and lower Round Mountain Silt; Keen, 1943). The upper part of the Olcese Sand is assigned to the Relizian Stage (Church and Krammes, in Church et al., 1957; Rudel, 1965). Olcese Sand (Hoots, 1930, Tejon Hills; Addicott, 1965b, p. C108). The Round Mountain Silt is assigned to the Relizian and Luisian Stages (Weaver et al., 1944; Church and Krammes, in Church et al., 1957). Diatoms in the Round Mountain siltstone suggest ages of 16–15 Ma (Olson, 1988, p. 196).

Deposition of the Monterey Formation took place between 17.85 5 0.10 and 7.5 Ma (DePaolo and Finger, 1991). There is a correlation of a d18O increase and the 14.8–13.7 Ma part of the Monterey Formation that is present between lat 35 and 348N along the Santa Barbara coastline and west of the San Andreas fault (DePaolo and Finger, 1991); and there is a correlation of an increase in deep-sea benthic d13C with the 14.5–14.1 Ma Monterey Formation (Woodruff and Savin, 1991). The major increases in d18O from 14.8 to 13.7 Ma and in d13C from 14.5 to 14.1 Ma represent a combination of an increase in high-latitude, cold deep water and growth of the East Antarctic ice sheet (Shackleton and Kennett, 1975; Kennett, 1986a; Miller et al., 1987; Wright et al., 1992). Deep-sea d18O and d13C records from 16–13.5 Ma sedimentary rocks suggest that episodic high-latitude, deep-water biologic production and East Antarctic ice growth can be correlated closely to the global carbon cycle (Woodruff and Savin, 1991; Flower and Kennett, 1993a).

See discussion of the 8–5 Ma time slice for this latitude.

;33–32

Imperial Valley–Riverside region Rocks in this region were deposited in a separate basin from that containing coeval rocks deposited to the west between these latitudes. Imperial Formation (Hanna, 1926; Christiansen, 1957; Mount, 1974; Bell-Countryman, 1984; Smith, 1991a, p. 67, 1991b, p. 644) (the basal Latrania Sandstone Member of the Imperial Formation overlies the Alverson Andesite; the latter is assigned an age of 16 Ma [Eberly and Stanley, 1978]; a basalt flow, assigned radiometric ages of 6.04 and 5.94 Ma, is in the Painted Hill Formation). The Painted Hill Formation overlies the Imperial Formation (see radiometric ages listed in Smith, 1991a, p. 4, 1991b, p. 644– 646). Based on bracketing radiometric ages, the Imperial Formation is younger than 16 Ma and older than 6 Ma; in this study the Imperial Formation is included in the 13–8 Ma time slice, although the formation could also be older (e.g., partly in the 17– 13 Ma time slice). Powell (1985, 1988, p. 13) restricted the Imperial Formation in Riverside County to the late Miocene (i.e., ca. 10–5 Ma). The Imperial Formation, which crops out in Imperial County and to the south of Riverside County, is “slightly older than 4.27 to 4.20 Ma” (Powell, 1988, p. 13). Matti et al. (1985) assigned an age range to the Imperial Formation of ca. 12.5–6.5 Ma, with the Latrania Sand (sic) Member to a time range of ca. 12.5–10 Ma. The Imperial Formation is assigned to the 13–8 Ma time slice based on available radiometric ages; however, based on palinspastic restorations and tectonic considerations, it is suggested that most of the Imperial fauna is ,10 to ,5 Ma in age.

The Bear River Formation (Martin, 1916) in the Eel River area is in part late Miocene and Pliocene in age (Aalto et al., 1995b); however, Crain and Thurston (1987) assigned the formation to a Relizian Age, and Barron (1986a) assigned 15.5–14.2 Ma ages to the Bear River Formation. A K/Ar age of 9.8 Ma (Mohnian Age) was obtained on a tuff bed in the Bear River bed by Aalto et al. (1995a, 1995b).

;40–39

Mendocino region Clark (1940) reported middle Miocene rocks (Temblor Formation) from this region, based on the presence of Desmostylus, in the Covelo area. Desmostylus is also known from the upper Miocene Santa Margarita Formation in the Santa Cruz Mountains (Clark, 1981). VanderHoof (1937) reported the taxon from the Briones Formation (Mohnian Stage) in the San Francisco Bay region. Huey (1948) concluded that the Briones Formation referred to by VanderHoof (1937) should be assigned to the Oursan? Sandstone (Luisian Stage), and Hall (1958) concluded that it was from the Cierbo Formation (Mitchell and Repenning, 1963, p. 9). Desmostylus has an age range from early Miocene to late Miocene (Mitchell and Repenning, 1963). Perhaps the rocks at Round Valley in the Covelo district, Mendocino County, are part of the Bear River unit, as described by Aalto et al. (1995b); they are no older than late medial Miocene (Luisian Age) to late Miocene (Mohnian) in age.

San Luis Obispo to Santa Maria region Pancho Rico Formation. Addicott (1978a, p. 85, 1978b) (see also Durham and Addicott, 1965; Barron, 1986a) correlated the Pancho Rico Formation with the Panorama Hills Formation 80 km to the south and on the east side of the San Andreas fault. Addicott (1972, p. 16) listed a molluscan fauna from the type locality of the Panorama Hills Formation and assigned a “Jacalitos Age” to the assemblage. Dibblee (1962) first defined the Panorama Hills Formation and noted that it grades laterally into the Bitterwater Creek Shale and nonmarine gravel. On his map of the Carrizo Plain and adjacent regions, Dibblee (1973b) assigned the name “unnamed marine sediments (Tu)” to the same rocks that he had mapped and described as the Panorama Hills Formation (Dibblee, 1962, 1968). Dibblee (1973b) depicted the “unnamed marine sediments” on his Carrizo Plain map interfingering with the Bitterwater Creek Shale. Both the “unnamed marine sediments” and the Bitterwater Creek Shale are depicted as unconformably overlying the Santa Margarita Formation (Dibblee, 1973b; Nilsen, 1987a). The Pancho Rico Formation is here correlated with the Saucelito Member, subunits 3 and 2 of the upper Santa Margarita Formation in the Huasna syncline, and the upper Miguelito and upper Edna Members of the Pismo Formation (Hall, 1962a, 1966, 1973a, 1973b; Hall and Corbato´, 1967; Keller and Barron, 1993 [6.7–6 Ma part]; W. Steinkraus, in Downey, 1999, p. 20 [7.7–6.5 Ma part]). The Pancho Rico Formation is considered herein to have been offset by the San Andreas fault by 145 km. It also is considered to be correlative in part with the Sisquoc Formation, it is younger than the Santa Margarita Formation, and it is older than the Etchegoin and Purisima Formations. The Pancho Rico Formation and its faunal assemblages are included within the 8–5 Ma time slice because the formation is within this age range. However, a separate paleoshoreline map is draw for the Pancho Rico Formation and its correlative units because the offset of this formation along the San Andreas is greater than the offset of the somewhat younger Etchegoin and Purisima Formations (72 km) that are also within the 8–5 Ma time slice.

Santa Maria–Cuyama region Tinaquaic Member of Sisquoc Formation (Woodring and Bramlette, 1950). Todos Santos Member Sisquoc Formation (ca. 7–4.6 Ma). Barron (1986a) assigned a 6–5 Ma age range to the Sisquoc Formation (also see Barron and Ramirez, 1992). Lower Sisquoc Formation. Dumont and Barron (1995) assigned to ages of 6.0–5.1 Ma, and they assigned this unit to the chron 3A (in part), and to the CN12 and part of the C11 calcareous nannofossil zones. Castaic Formation (Johnson, 1952; Stanton, 1966) (east of the San Gabriel fault). The fauna from the Castaic Formation is included in the 8–5 Ma time slice because of the overlapping age ranges of the following taxa present in the formation: Anadara (Anadara) montereyana (23–13 Ma), A. (A.) trilineata (13–2.5 Ma), Pacipecten discus (13–8 Ma), Swiftopecten parmeleii parmeleii (8–2.5 Ma), Lyropecten estrellanus (13–8 Ma), L. crassicardo (18–8 Ma), Turritella cooperi (13 Ma– Holocene), Turritella aff. T. freya (18–8 Ma), and Astrodapsis fernandoensis (8–5 Ma). It is likely that this fauna is within the early part of the 8–5 Ma time slice and within the late part of the 13–8 Ma time slice.

Pico Formation† San Diego–Baja California Sur, Mexico, region Almejas Formation crops out at lat ;288 N (Smith, 1984). Smith (1984, p. 203) correlated a part of the Almejas Formation with the Pliocene San Diego Formation, and Minch et al. (1976, p. 174) assigned a “middle to early late Pliocene” age to the formation. Nevertheless, Smith (1984, p. 206–207) assigned the molluscan fauna within the Almejas Formation to a “late Miocene” to “early Pliocene” age, and this age assignment is used herein.

Crescent City region Wimer Formation (Aalto et al., 1995b); however, because this formation contains Pacipecten discus (Conrad), a species common in rocks of early Mohnian Age, the Wimer fauna is in included in the 13–8 Ma time slice and not the 8–5 Ma time slice.

;41–40

Eel River basin-Scotia Bluffs region Eel River Formation (in part) (Obradovich et al., 1978 assigned a K-Ar age of 5.3 Ma) and Pullen Formation (in part) of Wildcat Group (Ogle 1953; Faustman, 1964; Crain and Thurston, 1987) (a late Miocene age was questioned by Faustman, 1964). Bear River and Bear Ridge units of Diller (1902). Falor Formation (Manning and Ogle, 1950). The Bear River Formation (Martin, 1916) or unit in the Eel River area is in part late Miocene and Pliocene in age (Aalto et al., 1995b); however, Crain and Thurston (1987) regarded this formation as Relizian in age, and Barron (1986a) assigned the Bear River Formation to an age range of 16.5–14.2 Ma (see discussion of age in Haller, 1980; Aalto et al., 1995a, 1995b).

;40–39

Mendocino region Clark (1940) reported middle Miocene rocks (“Temblor Formation”) based on the presence of Desmostylus in rocks in the Covelo area. This marine vertebrate taxon is also known from the upper Miocene Santa Margarita Formation in the Santa Cruz Mountains (Clark, 1981). VanderHoof (1937) reported the taxon from the Briones Formation (Mohnian Stage) in the San Francisco Bay region. Huey (1948) concluded that the rocks referred to as the Briones Formation by VanderHoof (1937) should be assigned to the Oursan (?) Sandstone (Luisian Stage), and Hall (1958) concluded that the rocks should be assigned to the Cierbo Formation. Thus, Desmostylus is not restricted either to the miedial or late Miocene ages. Perhaps the rocks at Round Valley in the Covelo district, Mendocino County, are part of the Wildcat Group or they are part of the Bear River unit (see Table A4).

;39–38

Santa Rosa–Petaluma region A part of the Merced Formation of Osmont (1905) and Dickerson (1922) (Wilson Ranch), Ohlson Ranch Formation of Higgins (1960) and Peck (1960), and Wilson Ranch Formation or beds of Weaver (1949) and Fox (1983) could be as old as 5 Ma (Sarna–Wojcicki, 1976), but the rocks are principally Pliocene in age, and their molluscan faunas are included in the 5–2.5 Ma time slice (Fox, 1983, p. 9–10). The lower Wilson Grove Formation is within the 8–5 Ma time slice (6.3 and 5.9 Ma; Fox, 1983). The Pliocene embayment (Plate 8A) in this region was present (but it is not shown on Plate 6A) during the latest Miocene or earliest Pliocene. Allen (1999) proposed that the Wilson Grove Formation is equivalent in age to the Delgada Fan, which is offshore from Point Delgada, and that the fan has been offset northward 200 km along the San Andreas fault.

Devils Den–Wheeler Ridge–southern San Joaquin Valley region Etchegoin Formation (Reid, 1995 [paleogeography depicted but no fossils listed]). The plutonic-sourced Lower Etchegoin Formation, equivalent to the Jacalitos Formation, is transitional between the outer neritic, fine-grained clastic Reef Ridge Shale below and basin sedimentary rocks of the volcanogenic-rich Upper Etchegoin Formation above; the latter is characterized by nearshore marine bars, and back-bar and lagoonal depositional systems. Reef Ridge Shale (Dibblee, 1973a; Reid, 1995) and correlative Belridge Diatomite (Reid, 1995) (but not correlative according to Dibblee, 1973a).

(1994) reported radiometric ages of 6.0–5.4 Ma for a tuff in the “Pico” Formation and diatoms with a biostratigraphic age assignment of 5.8–5.6 Ma. These ages place the Pico Formation within the 8–5 Ma time slice; however, the Pico Formation is assigned to the 5– 2.5 Ma time slice herein because some of the molluscan assemblages in the formation are considered to be Pliocene in age. § The 4.1 Ma age (tephrochronology) of a tuff unit in the Etchegoin Formation, dated by Sarna–Wojcicki (1976) and Sarna–Wojcicki et al. (1979, 1991) and correlated with the Lawlor Tuff (4.1 Ma), is also considered to be suspect and too young, based on the ages of the Etchegoin Formation determined by Loomis (1990c, 1992a, 1992b). The base of the Etchegoin Formation was assigned an age of 7.5–6.5 Ma (Rentschler and Bloch, 1988).

(1984), and Wagner et al. (1990) assigned the “Merced” in this region to a Pliocene age. The Merced Formation at Bolinas Bay (Martin, 1916) is in juxtaposition against the San Andreas fault zone. The Merced Formation at Mussel Rock (Martin, 1916; Glen, 1959) was assigned to the Purisima Formation by some (see review by Addicott, 1969b; Axelrod, 1971; see also Dorf, 1930).

Others (Sorlien et al., 1999b) assigned an age of from 6 to ,5.3 Ma. Foxen and Careaga formations (Woodring and Bramlette, 1950). Behl and Ingle (1998) inferred that the Foxen Mudstone was deposited in several oxygen-deficient troughs at the shelf edge; they didn’t depict the location of the troughs and there isn’t sufficient paleoshoreline control in order to show troughs in Plate 8B. Sorlien et al. (1999b) assigned an age of 3.4 Ma to the lower Foxen Mudstone and 3.4 to ca. 2.3 Ma to the undifferentiated upper Foxen Mudstone and Careaga Formation.

However, the tectonic history (compression, extension, and strike-slip faulting) along the Coast Range fault or fault zone is complex, involving imbricate thrust faulting, low-angle detachment, and high-angle reverse faulting. The present juxtaposition of the Coast Range ophiolite and Great Valley sequence with the Franciscan Complex is locally controlled by late Cenozoic high-angle faults.

*Calaveras fault, part of the Hayward–Green Valley–Concord–Greenville fault zone (Wagner et al., 1990; Unruh and Lettis, 1998). Dickinson (1997) proposed right slip of 100 km along the Calaveras fault and 60 km along the Hayward fault. Anderson et al. (1995) suggested that there was movement along the Hayward fault after 10 Ma, and along the Calaveras fault after 6 Ma. California Division of Mines and Geology (1996) proposed a slip rate of 15 mm/yr on the Calaveras fault. Unruh and Lettis (1998) proposed that the cumulative slip rate on the Hayward fault is ;6–8 mm/yr, i.e., 60–80 km during the past 10 m.y. Freymueller et al. (1999) proposed a slip rate of 8 mm/yr on the Green Valley fault. The 174 km of right-lateral cumulative offset on faults in the east San Francisco Bay region suggested by Jachens et al. (1998), and the 100 and 60 km right-slip amounts suggested by Dickinson (1997) are seemingly incompatible with the distribution of Neogene rocks and shorelines. A composite amount of slip on the Calaveras (right-slip onset ca. 3.5 Ma) (Page, 1984, 1999) and Hayward faults (right-slip onset ca. 10 Ma) is taken to be 35 5 10 km (Graham et al., 1984; Dickinson, 1996), and this figure is used in the palinspastic restorations for Plates 5 and 6. Based on the research of others mentioned here, the amount of slip used in the reconstructions in this volume could be too small, but relative to offset paleoshorelines in the east San Francisco Bay area it provides a best fit for the palinspastic maps in this paper. Other estimates of slip that have been proposed are those of McLaughlin et al. (1990) of ;190 km, and Page (1990) and Sarna-Wojcicki (1992) of 60 km along the Hayward-Calaveras trend and Calaveras fault. Buising and Walker (1995) proposed net slips and time of slip onsets of 20 km and 3.5 Ma, and 43 km and 10 Ma for the Calaveras and Hayward faults, respectively. A proposed offset pair along the Hayward fault is the Tolay Volcanics, which are apparently offset 65 5 13 km northward from the Berkeley Hills volcanic rocks; the Tolay Volcanics have moved along the Hayward– Rodgers Creek fault trend. This offset is based on matching midpoints of the outcrop areas of the Tolay and Berkeley Hills volcanic rocks (see McLaughlin et al., 1996). † The amounts of slip used in the palinspastic reconstructions of the Garlock fault are 45 km in the west and 65 km in the east (Burchfiel and Davis, 1972, 1981; Davis and Burchfiel, 1973; Burbank and Whistler, 1987); these two different offsets are difficult to depict and they result from differences in extension north and south of the Garlock fault. Initial movement occurred ca. 10 Ma (Monastero et al., 1997). § Hayward fault (see Calaveras fault): Sedlock (1995) divided the faults in the eastern San Francisco Bay region into the Hayward–Rodgers Creek fault system, and the Calaveras-Concord-Greenville fault system. From Figure 3 of Wakabayashi and Hengesh (1995), it can be inferred that these authors would include the Maacama fault north of the Rodgers Creek fault in the same system. The Hayward, Rodgers Creek, and possibly the Tolay and Maacama faults may be a part of the same system, and the Calaveras, Concord, and Greenville faults a part of the same regional system or the same system; however, these faults are not continuous. Freymueller et al. (1999) proposed slip rates of 14 mm/yr on both the Rogers Creek and Maacama faults. Graymer (1999) proposed that there has been 93–130 km of offset along faults in the Hayward fault zone. See Koenig (1963) and Wagner and Bortugno (1982) for the surface relationships of these faults, and Lienkaemper et al. (1997) for the location and relationship to other faults within the region. Parsons and Hart (1999) proposed that the San Andreas and Hayward faults converge into a single fault zone in the upper mantle. McLaughlin et al. (1996) and Underwood et al. (1999, Fig. 16) included the San Andreas, Rogers Creek, Tolay-Bloomfield, Hayward, and Calaveras faults in the east San Francisco Bay region fault system that was initiated ca. 8 Ma when the Mendocino fracture zone moved eastward. # The geometry of the Mojave block is highly depictive owing to difficulties associated with cartographic restorations. There was transrotational shear from 13–12 to 6 Ma generated by deformation of the eastern Transverse Ranges (ETR), and the shear was unevenly transmitted throughout the Mojave block (MacFadden et al., 1990a, 1990b; Schermer et al., 1996; Dickinson and Wernicke, 1997; see also Schott and Johnson, 1998). **Navarro structural discontinuity (McCulloch, 1989b): the Point Arena basin is floored by Mesozoic granitic rocks and Franciscan me´lange, and the structural discontinuity or boundary is a seismic structural anomaly (Foland, 1998). Wentworth et al. (1998) (see also Brabb et al., 1998; Jones et al., 1998) suggested that the Cretaceous sedimentary rocks beneath the Point Arena basin, with a “basal ophiolite,” cannot be part of Salinia. However, the Cretaceous sedimentary rocks are separated from the ophiolite by a fault. In addition, elsewhere in the Coast Ranges (e.g., Hall et al., 1995, Plate 1), the Coast Range ophiolite is ,1 km from rocks within Salinia, it is tectonically in contact with Franciscan me´lange, and both the ophiolite and Franciscan me´lange are structurally beneath Cretaceous rocks within Salinia. The discontinuity separates granitic rocks from the Franciscan Complex (Foland, 1998). The discontinuity is considered here to be the sole of the Southern California allochthon and the S-NF, i.e., the fault that separates Cretaceous rocks from ophiolite. However, Burnham (1998c) concluded that the Navarro discontinuity is the offshore continuation of the Pilarcitos fault. Jachens et al. (1998, Fig. 12) and McLaughlin et al. (1998) palinspastically restored the Point Arena region or Gualala block with the Santa Cruz Mountains and inferred that Salinian granitic rocks have been underthrust by mafic masses or ophiolite. †† McLaughlin et al. (1994) and Underwood et al. (1999) questioned the location of the San Andreas fault and continuation of right slip along the fault east of Point Delgada and through Shelter Cove. Others have placed the San Andreas fault east of Point Delgada, through Shelter Cove, and they have credited the fault with an important role within the plate boundary system north of Point Arena (Brown, 1995; Hart, 1996, Thatcher et al., 1997, Prentice et al., 1999). The latter interpretation was used in the palinspastic reconstructions herein. Drake et al. (1987) proposed that the Delgada Fan (near lat 408N) grew between the latitudes of near San Francisco to near Petaluma (see Plate 8A) between 6 and 7 Ma and that by ca. 2 Ma it had moved northward 150–200 km. The slip rate on the San Andreas fault system using these figures was between 3 and 5 cm/yr. Allen (1999) proposed that the Wilson Grove Formation (Petaluma–Santa Rosa region, Plate 8A) has an age range of between 5 and 6 Ma, that the Delgada Fan was at the latitudes of the Wilson Grove Formation during the deposition of the formation, and that the San Andreas fault had separated the fan from the formation by ;200 km. The slip rate on the San Andreas–San Gregorio–San Simeon– Hosgri fault system using these figures was 3.3 cm/yr. Prentice et al. (1999) suggested that the Holocene slip rate on the San Andreas fault near Point Delgada is 1.4 cm/yr. continued

TABLE A16. ABBREVIATIONS, SYMBOLS, AND NOTES FOR PLATES 1–8 (continued) Initial slip on the central part of the SAF began at 12 or 13 Ma, the approximate time of the initial movement on the San Gabriel fault (SGF). Slip on the northern part of the SAF could have begun later than 12 or 13 Ma (Plates 5A and 6A). Slip on the southern SAF initiated ca. 6 Ma (Plate 6B). Slip was related to transrotation of the western Transverse Ranges. Significant slip along the northern SAF and Reliz–Rinconada–East Huasna fault (R-R-EHF) is depicted after 10 Ma (Plates 6 and 7). Slip of 315 5 10 km along the central SAF (Stanley, 1987; Graham et al., 1989; Dickinson, 1996) and slip on the southern SAF of 240–270 km, which includes 26 5 2 km of slip on the San Jacinto fault (Sharp, 1967, 1975, 1981; Bartholomew, 1970) or 255 km (Dickinson, 1996; Oskin et al., 2001), are offsets used in the construction of the palinspastic maps in this volume. The principal offset along the SAF is depicted on the 5–2.5 Ma paleoshoreline map, based on offsets between the Oligocene– Miocene, Miocene, and Pliocene, Vasquez, Caliente, Mint Canyon, Hungry Valley Formations in the Mount Pinos, Frazier Mountain, and Hungry Valley areas, and their coeval counterparts in the Orocopia and Chocolate Mountains (e.g., Diligencia Formation and Morongo Valley regions; Crowell, 1962, 1982a, 1982b; Bohannon, 1975; Ehlig et al., 1975; Ramirez, 1983). Law et al. (2001, p. 217) questioned the correlation between the Diligencia, Vasquez, and Plush Ranch Formations. Ramirez (1983) favored a correlation between the upper Miocene and lower Pliocene Hungry Valley (HV) Formation and a conglomerate in the Morongo Valley (MV). However, the palinspastic reconstructions of the 8–5 Ma paleoshorelines do not support this correlation. The correlation between the Hungry Valley Formation and rocks in the Cajon Pass (CajP), proposed by Meisling and Weldon (1989), is used in this study. Their timing of movement and the related offsets best accommodate the palinspastic reconstructions for the 13–8 Ma and 8–5 Ma marine shorelines. However, compelling alternatives to this timing and offsets are in the detailed analyses of the San Andreas fault provided by Dickinson (1996, 1997) and Dickinson and Wernicke (1997) (see also Hill and Dibblee, 1953; Gastil, 1968, 1975; Suppe, 1970, 1972; Huffman, 1972; Ehlig et al., 1975; Gastil et al., 1978; Kistler and Peterman, 1978; James, 1986; Powell, 1982, 1986; Stanley, 1987; James and Mattinson, 1988; Graham et al., 1989; Dillon and Ehlig, 1993; James et al., 1993; Atwater and Stock, 1998; Wernicke and Snow, 1998). A more detailed map of the San Andreas fault system than depicted in Plate 1B south of lat 328N was provided by Fletcher and Munguıá (2000). ## The sole of Salinia or the Southern California allochthon (Hall, 1991) is the Sur-Nacimiento fault (solid barbs). James et al. (1993) and Wentworth et al. (1998) did not include the Point Arena area within Salinia, whereas Mattinson (1990) did (see review in Whidden et al., 1998, p. 329; see also Ross, 1970, 1972a, 1972b, 1976, 1977a, 1977b, 1978, 1980, 1984; Wiebe, 1970a, 1970b; Silver, 1983, 1988; Silver and Mattinson, 1986; Silver and James, 1989; Champion and Kistler, 1991; Dickinson et al., 1991; Pickett and Saleeby, 1991; Whidden et al., 1991, 1998; Saleeby, 1997; and Dickinson and Butler, 1998). See Navarro structural discontinuity (NAVD and NSD). There was emplacement and crystallization of the granitic rocks in Salinia from 104.0 5 4.0 Ma to 117.0 5 12 Ma based on 206Pb/238U, Rb/Sr, and Th-Pb ages (Mattinson, 1978, p. 238). See palinspastically restored elements of the Salinian plutons (,83 Ma, 83–95 Ma, and 95–120 Ma) along San Gregorio–San Simeon–Hosgri fault (Mattinson and James, 1985, p. 220). Hall (1991) concluded that the allochthon moved westward and northwestward along the Sur-Nacimiento fault between 65 and 67 Ma. This timing is consistent with the resetting of the crystallization ages of the granitic rocks in Salinia between 60 and 68 Ma or 60 and 74 Ma based on fission-track ages of sphene and apatite (Naeser and Ross, 1976; Mattinson, 1978). ***Slip along the San Gabriel fault was between 13 and 12 Ma (Ingersoll and Rumelhart, 1999) (Plate 5, B and C). Right slip of 60 5 5 km is inferred (Crowell, 1962, 1968, 1975, 1981, 1982a; Bohannon, 1975; Yeats et al., 1994). The nomenclature for this fault follows that of Dibblee (1989). Alternative nomenclature and interpretations of the San Gabriel fault zone were provided by Dolan et al. (1993, 1997, Fig. 1), Ingersoll and Rumelhart (1997, 1999), and Fritsche (1998). ††† San Gregorio–San Simeon–Hosgri fault zone (SG-SS-HF is present from near San Francisco to near Point Conception (Plate 1). The length of the right-slip fault is 427 km. Powell (1993) proposed that initial movement on the SG-SS-HF began coevally with the San Gabriel fault, i.e., ca. 12 Ma. Clark et al. (1984) proposed that initial slip on the San Gregorio fault began between 12 and 11 Ma, but not before 10 Ma. Clark (1998) later concluded that the initial right slip began at 10 Ma. In this volume, right-lateral slip along the SG-SS-HF is considered to have begun between 13 and 8 Ma for purposes of the palinspastic reconstructions (Plate 6, A and B). The SG-SS-HF is an active fault. The fault or faults in the fault splay of the SG-SS-HF locally offset the lowest marine terraces and present-day soil horizons, the fault has locally beheaded streams, and its trace is locally manifested by springs, sag ponds, and pressure ridges (e.g., Greene et al., 1973; Weber, 1977; Hall, 1976, 1991; Hall et al., 1994). Along the northern, or San Gregorio, part of the SG-SS-HF there has been right-lateral slip of 150–160 km (Clark et al., 1984); or 100 km of slip since 8 Ma, i.e., 50–60 km between 10 and 8 Ma; 81 km between 8 and 3 Ma; and 19 km between 3 and 0 Ma (Clark, 1998). Burnham (1998a, 1998b, 1998c, 1999) concluded that there has been 150–185 km of right-lateral slip on the San Gregorio fault, and Stanley and Lillis (2001) have suggested 115 5 10 km of displacement after 7 Ma. There was Miocene–Pliocene right slip of 110–115 km along the central part of the SG-SS-HF (Graham and Dickinson, 1978a, 1978b; Dickinson, 1983, 1996); 87–95 km of slip along the south-central part of the fault (Hall et al., 1995); and 10.5 km of dextral slip near the southern terminus of the fault (Sorlien et al., 1999a). South of the town of Monterey, southwestnortheast compressive folding along the SG-SS-HF can account for the differences between inferred values of slip north and south of Monterey. Near the southern terminus of the fault zone right-slip offset is taken up by right-slip, westward-stepping faults offshore along the Santa Lucia Bank fault zone (Steritz, 1986; Steritz and Luyendyk, 1994). During the latest Pliocene, Pleistocene, and Holocene the fault locally became a low-angle fault zone, e.g., near Point Sal (Crouch et al., 1984), and near Point Conception (solid barbs on Plate 1B) (Steritz, 1986; Steritz and Luyendyk, 1994; Sorlien et al., 1999a). Some researchers have inferred an upper crust, horizontal detachment surface, or dećollement in this region (Crouch et al., 1984). Steritz and Luyendyk (1994) and Sorlien et al. (1999b) concluded that the Hosgri and nearby Purisima and offshore Lompoc faults are truncated by the North Channel fault. Sedlock and Hamilton (1991) considered the geologic data that had been used to infer large right-slip offsets along the SG-SS-HF to be ambiguous. They concluded that there has been only 5–10 km of right slip on the SG-SS-HF based on their tectonic model outlining the structural evolution of California. However, Powell (1993) considered offsets of 80 or 150 to 160 km for the amounts of inferred right slip along the SG-SS-HF fault in his balanced palinspastic reconstruction of the pre-late Cenozoic paleogeology of California. Dickinson (1996; and modifications of his synthesis, Dickinson and Wernicke, 1997), in his model for the kinematics of the transrotation of the Transverse Ranges and the contributions of the transrotation of the Transverse Ranges and extension in eastern California to slip along the San Andreas fault system, concluded that at least 110 km of right slip along the SG-SS-HF fault was required to balance strike-slip offsets for the San Andreas fault system. Underwood et al. (1995) and Underwood and Laughland (2001), based on thermal maturity trends in the Franciscan Complex, concluded that: (1) there has been only 5–10 km of right slip on the SG-SS-HF, (2) the San Gregorio fault is linked to the Palo Colorado fault and not directly to the San Simeon fault, (3) the “San Gregorio–San Simeon–Hosgri fault (?)” in the Point Sur area is part of the Sur fault zone, and (4) the “Sur fault zone appears to play a relatively insignificant role in the late Cenozoic evolution of central California” (Underwood et al., 1995, p. 839, Fig. 2). These four points are discussed in the following. §§

1. Underwood et al. (1995) and Underwood and Laughland (2001) concluded that there has been only 5–10 km of right slip along the SG-SS-HF. This conclusion is in sharp disagreement with the 80 km or more of right slip along the SG-SS-HF that has been inferred based on (1) geophysical studies (Silver, 1974b, 1978; Mullins and Nagel, 1981; Nagel and Mullins, 1983; Griscom and Jachens, 1989); (2) offset stratigraphic pairs, pairs of stratigraphic sequences, and narrowly geographically distributed pairs of uncommon lithologic types across the SGSS-HF (Hall, 1975b; Graham and Dickinson, 1978a, 1978b; Clark and Brabb, 1978; Graham and Peabody, 1981; Clark et al., 1984; Hall et al., 1995; Sutherland, 1990; Brabb et al., 1998; Burnham 1998a, 1998b, 1998c, 1999; Clark, 1998); (3) offset submarine geology (Greene, 1977); (4) geochemical studies across the fault (Champion and Kistler, 1991; Kistler and Champion, 1991); (5) provenance studies across the fault (Hall et al., 1995); and (6) palinspastic shoreline reconstructions (Hall et al., 1995; this study). See also Silver (1971, 1974a), Silver et al. (1971), Greene et al. (1973), and Ross (1984) for additional supporting data in order to demonstrate right slip measured in tens of kilometers along the SG-SS-HF. In contrast to this large body of geologic evidence that supports measured right slip of more than 80–150 km along the SG-SS-HF, Underwood and Laughland (2001, Fig. 10) inferred the locations of their 240 and 190 8C thermal maturity isotherms that they purported indicates only 105 km of right slip. Their interpretation lacks critical control in the offshore area west of the SG-SS-HF. For example, they have not provided data for the offshore area west of the SG-SS-HF, i.e., in the .60 km distance from near Point Sur to near Piedras Blancas, or for the offshore area west of the SG-SS-HF region anywhere south of San Simeon. Values of vitrinite reflectance can vary laterally and longitudinally over a short distance (Underwood and Laughland, 2001, Fig. 10, east of SG-SS-HF and north and south of lat 358308N). There is no firm basis for their isotherm spacing north of the Los Burros Gold District, specifically the location of their inferred 240 8C isotherm. South of Los Burros the “location and orientation of 190 8C contour inboard of the San Simeon fault are poorly constrained” (Underwood and Laughland, 2001, Fig. 10 caption). There is nothing in their Figure 10 to suggest a unique correlation of their isotherms. It is possible that the isotherms in the Point Sur area can be correlated with some geometry of isotherms in the Morro Bay region. These areas, on opposite sides of the SG-SS-HF, were correlated by Hall et al. (1995) Underwood et al. (1999, Fig. 16) depicted the San Gregorio–Hosgri fault as being more than 200 km long (the complete length of the fault is not shown in their figure), with Salinia west of the “San Gregorio–Hosgri fault.” They depicted the fault as a major tectonic boundary. The location of Point Reyes at 8 Ma is shown in their Figure 16. It can be inferred from their Figure 16 that Point Reyes has moved at least 138 km northward along the “San Gregorio–Hosgri fault” and San Andreas fault. Thus the inference drawn from the Underwood et al (1999) paper seems to be in conflict with the Underwood and Laughland (2001) paper that purports to show only 105 km of right slip. 2. Underwood et al. (1995) inferred that the San Gregorio fault is linked to the Palo Colorado fault. This inference is questioned because the Palo Colorado fault terminates 35 km southeast of the Monterey Bay coastline (Jennings, 1977, 1992; Majmundar, 1984; Roberts et al., 1990); Jennings and Saucedo, 1994). Ross (1976) and Hansen and Stuk (1993) depicted the Coast Ridge fault (not to be confused with the Coast Range fault) as a southeast continuation of the Palo Colorado fault, which could add another ca. 30 km of length to the system. The Palo Colorado fault cannot accommodate 100 to 150 km of right slip along the San Gregorio fault (see Clark, 1998), although some of the 150 km of right slip measured north of Monterey Bay could be accommodated in a Palo Colorado splay fault of the San Gregorio fault. Published geologic maps show the San Gregorio fault zone as a continuous structural feature south of Monterey Bay, and the zone is in line with the high-angle fault zone on land near Point Sur, a fault zone offshore from Cape San Martin, a fault zone onshore near San Simeon, and a fault zone in the offshore from near San Simeon to Point Sal (Jennings, 1977, 1992; Majmundar, 1984; McCulloch, 1989a, 1989b; McCulloch and Greene, 1990; Roberts et al., 1990; Jennings and Saucedo, 1994). The continuation of the SG-SS-HF offshore near and south of Point Sal is depicted as a continuous trace by Steritz and Luyendyk, 1994). The trace of the San Gregorio fault zone south of Monterey Bay in the offshore can also be inferred from aeromagnetic maps (Young, 1988; Mattinson and Young, 1989). 3. Underwood et al. (1995, Fig. 2) and Underwood and Laughland (2001, Fig 10) depicted the “San Gregorio–San Simeon–Hosgri fault (?)” in the Point Sur area as part of the Sur fault zone. Based on my detailed mapping of the Point Sur area their figures lead to an erroneous conclusion. A strike-slip fault in the Point Sur area brings the Sur Complex into juxtaposition with the Franciscan Complex and unconformably overlying lower to upper Miocene rocks between Hurricane and Grimes points on the Point Sur headland (Hall, 1991, Plate 1). The plane of this fault is vertical to near vertical, as observed in exposures along sea cliffs, and the trace of the fault is characterized in part by offset stream valleys, a beheaded stream, pressure ridges, and a sag pond. This active fault, part of the San Gregorio–San Simeon segment of the SG-SS-HF, is neither the Sur fault nor a part of the relatively low-angle Sur fault zone. The Sur fault separates Mesozoic and older rocks; it was active between 67 and 65 Ma (Hall, 1991), and it is older than 25 Ma (Page, 1970b; Hall et al., 1979, map sheet 3). The relationship of the SG-SS-HF to the Sur-Nacimiento fault was shown by Hall (1991) and is on Plate 1A herein. 4. Underwood et al. (1995, p. 839 and Fig. 2) concluded, “Sur fault zone appears to play a relatively insignificant role in the late Cenozoic evolution of central California.” This conclusion is agreement with the inference that the Sur-Nacimiento fault was active between 67 and 65 Ma (Hall, 1991) and can be no younger than 25 Ma (Page, 1970b). Sorlien et al. (1999a, p. 1039) noted that the Hosgri fault terminates to the southeast into folds and reverse-separation faults. They concluded from their three-dimensional map restoration that there has been no more than 10.5 km of post-Miocene right slip and dextral shear along the Hosgri fault. Sorlien et al. (1999a) did not imply that this is the maximum dextral slip along the SG-SS-HF, it is only the amount of slip that can be measured near the southern terminus of the fault zone. A partial summary of types of evidence and references for 80 km or more of right slip along the SG-SS-HF is provided in the previous paragraphs and cited references. Specific to the Hosgri fault, the unique offset stratigraphic pairs of ophiolite zones, green tuffaceous chert, Upper Jurassic–Lower Cretaceous shale, redbeds and tuff of the Lospe Formation, Point Sal Formation, and distinct lithologic facies in the Monterey Formation near Point Sal and San Simeon provide compelling evidence for large right-slip (Hall, 1975; C. Hopson, 1999, personal commun. [regarding the similarity of the ophiolite zones at Point Sal and north of San Simeon Point across the SG-SS-HF]). Paleoshoreline reconstructions also support the notion of large right-slip offsets (Hall et al., 1995; this study). Steritz and Luyendyk (1994) noted the discrepancy between the inferred displacements north of the Hosgri fault and south of Point Sur. In order to account for the discrepancy they proposed 20 km of ductile shortening and thrust faulting east of the Hosgri fault, 60 km of right slip along northwest-southeast–trending splays of the Hosgri fault zone, and 60 km of post-medial Miocene right slip distributed on the Santa Lucia Bank fault system (see McCulloch, 1980) and the releasing-bend step of the Hosgri fault zone south of Point Sur (see Hoskins and Griffiths, 1971). Sorlien et al. (1999a, p. 1042) proposed an alternative solution to the discrepancy and concluded, “the Hosgri fault has propagated to the south as a tear fault or partitioned strike-slip fault in conjunction with south propagation of the western Transverse Ranges fold and thrust belt and reactivation of older structures.”

TABLE A16. ABBREVIATIONS, SYMBOLS, AND NOTES FOR PLATES 1–8 (continued) Sorlien et al. (1999a, p. 1042) concluded that their model “implies a lower earthquake hazard to facilities such as the Diablo Canyon nuclear power plant.” Gawthrop (1978, p. 47 and Fig. 3) concluded that the epicenter of the Lompoc–Santa Barbara earthquake of 1927 (M 4 7.3) was on either the Hosgri fault or within the Santa Lucia Bank fault zone. He also noted that the epicenters of two 1969 earthquakes (mb 4 5.4 and 5.8) were within the Santa Lucia fault zone. Therefore, it would seem to be prudent to consider the 427 km length of the SG-SS-HF and evidence of movement along the fault zone that has taken place during the past 10 k.y. (Jennings and Saucedo, 1994), along with the proximity or location of epicenters of major earthquakes on the fault or segments of the fault zone in relation to nuclear reactors, as a potential geologic hazard. §§§ Sur-Nacimiento fault (solid barbs), sole of Southern California allochthon (Hall, 1991): the offshore location of the Sur-Nacimiento fault and Salinia is based on Mullins and Nagel (1981), Clarke et al.
