Late Quaternary Sciuridae from Kokoweef Cave, San Bernardino County, California
Kokoweef Cave is located at about 1770 m elevation in the Ivanpah Mountains, northeastern San Bernardino County, California. Fossils were re- covered from a 9-m-thick sedimentary sequence in the cave that may span several thousand years of latest Pleistocene and early Holocene time. We examined nearly 1500 specimens of the rodent family Sciuridae. Nine taxa, including five extra- limitals, were identified. Dominant species (Marmota flaviventris, Spermophilus townsendii, S. lateralis) are extralimitals found today in the Great Basin. Overall, taxonomic and ecologic stability characterized the local late Quaternary sciurid faunal record. Significantly, extralimitals seem to persist through the Pleistocene- Holocene transition.
