“…Marine terrace faunas, particularly those rich in mollusks, provide valuable information in reconstructing marine paleoclimates of the Quaternary (e.g., Valentine, 1961Valentine, , 1989Addicott, 1964Addicott, , 1966Kennedy, 1978Kennedy, , 2000Kennedy et al, 1982Kennedy et al, , 1992Spencer and Campbell, 1987;Roy et al, 1995;Muhs et al, 2002a,b). Species that are most important in paleoclimatic interpretation of marine terrace faunas are those whose modern geographic distributions extend only to the south (''extralimital southern'') or only to the north (''extralimital northern''), respectively, of any fossil locality (Kennedy, 2000).…”

New high-precision thermal ionization mass-spectrometric (TIMS) U-series ages of solitary corals (Balanophyllia elegans) from several marine terrace localities along the California and southern Oregon coasts date to the 80,000 yr BP high stand of sea, correlative with marine isotope substage 5a, late in the last interglacial complex. Ages of multiple corals from localities north of Point An˜o Nuevo (central California) and San Nicolas Island (southern California) suggest that this high sea stand could have lasted at least 8000 yr, from 84,000 to 76,000 yr BP. These ages overlap with those from marine deposits on tectonically stable Bermuda and tectonically emergent Barbados. Higher-elevation terraces at two California localities, in the Palos Verdes Hills and on San Nicolas Island, have corals with ages that range mostly from 121,000 to 116,000 yr BP, correlative with marine isotope substage 5e. These ages are similar to those reported for other terraces in southern California but are younger than some ages reported from Hawaii, Barbados and the Bahamas.Marine terrace faunas are excellent proxies for nearshore marine paleotemperatures during past high sea stands. Terraces on the Palos Verdes Hills and San Nicolas Island dated to the 120,000 yr BP high sea stand have dominantly zoogeographically ''neutral'' species in exposed coastal localities, indicating nearshore waters similar to those of today. In contrast, 80,000 yr BP, exposed coastal localities typically have molluscan faunas characterized by numerous extralimital northern species and a lack of extralimital southern species. These fossil assemblages are indicative of nearshore water temperatures that were cooler than modern temperatures at 80,000 yr BP. Waters at least as warm as today's at 120,000 yr BP and cooler than present at 80,000 yr BP are in excellent agreement with marine alkenone records and coastal vegetation records derived from pollen data, from both southern and northern California. Decreased insolation or increased upwelling seem inadequate to explain the cool waters off the Pacific Coast from southern Oregon to southern California at 80,000 yr BP. We propose that a stronger California Current (or at least one with a greater component of subarctic waters) may explain cooler-than-modern coastal waters during the 80,000 yr BP high sea stand. r

The fluid mechanics of marine and terrestrial systems are surprisingly similar at many spatial and temporal scales. Not surprisingly, the dispersal of organisms that float, swim or fly is influenced by the fluid environments of air and seawater. Nonetheless, it has been argued repeatedly that the geography of evolution differs fundamentally between marine and terrestrial taxa. Might this view emanate from qualitative contrasts between the pelagic ocean and terrestrial land conflated by anthropocentric perception of within-and betweenrealm variation? We draw on recent advances in biogeography to identify two pairs of biophysically similar marine and terrestrial settings-(i) aerial and marine microplankton and (ii) true islands and brackish seawater lakes-which have similar geographies of evolution. Commonalities at these scales, the largest and smallest biogeographic scales, delimit the geographical extents that can possibly characterize evolution in the remaining majority of species. The geographies of evolution therefore differ statistically, not fundamentally, between marine and terrestrial systems. Comparing the geography of evolution in diverse non-microplanktonic and non-island species from a biophysical perspective is an essential next step for quantifying precisely how marine and terrestrial systems differ and is an important yet under-explored avenue of macroecology.

“…For more than a hundred years, the Quaternary fossil record of Pacific Coast marine terraces has generated a rich literature on past marine climates (Arnold 1903, Grant and Gale 1931, Woodring et al 1946, Woodring 1957, Val entine 1958, 1961, 1962, Kanakoff and Emerson 1959, Valentine and Meade 1961, Vedder and Norris 1963, Addicott 1966, Lipps et al 1968, Kern 1977, Kennedy 1978, 2000, Susuki and Stadum 1978, Emerson 1980, Lindberg et al 1980, Emerson et al 1981, Kennedy et al 1982, Muhs et al 2002a, 2012a. One problem that has long been recognized in marine terrace fossil studies on the Pacific Coast is the existence of fossil assemblages with elements that imply contradictory paleoclimatic interpretations when set in the context of their modern zoogeography.…”
