Abstract

Terrestrial vertebrate remains were recovered from sediments that He on remnants of the lowest marine wave-cut platform between Point Buchon and Point San Luis. Uranium series ages of these samples, which range from 83 to about 49 ka suggest a correlation to late Pleistocene climatic and eustatic events associated with marine oxygen isotope substage 5a, and establish a maximum age of ~80 ka for the occurrence of terrestrial mammal fossils. The Point San Luis area assemblage appears typical of the late Pleistocene regional vertebrate paleo- fauna from west-central California. Five mammalian taxa are added to the Pleis- tocene record from San Luis Obispo County. Equus sp. cf. E. occidentalis, Ca- melops sp. cf. C. hesternus, and Bison antiquus were recovered from the Point San Luis area, and Mammut americanum and B. latifrons from near Morro Bay and the Carrizo Plains in eastern San Luis Obispo County.
