McKittrickAge. Mid/Late Wisconsin. The various localities in the vicinity of McKittrick apparently vary in age from mid Wisconsin to Holocene (Fox-Dobbs et al. 2014). 14C dates are summarized in Fox-Dobbs et al. (2014). As near as can be seen from published data, most of the vertebrate material is Mid or Late Wisconsin in age. A radiocarbon date of 38,000 ± 2,500 yr BP (Jefferson 1991a) has been considered questionable. A date on Hemiauchenia is 26,850 ± 590, but specific locality data were not given (Fox-Dobbs et al. 2014). Fox-Dobbs et al. noted that some upper levels include Holocene fauna and that much of the cervid material is from upper levels and likely late Pleistocene or early Holocene. Fox-Dobbs et al. reported three new dates on faunal elements (Panthera atrox, Arctodus simus, and Cervus elaphus), ranging from 15,290 ± 510 to 11,040 ± 310. For purposes here, the fauna is considered as Mid and Late Wisconsin with the caveat that a few taxa may be Holocene.

Jefferson (2014) reported as "Asphalto Number 2, (McKittrick)" an apparently mixed deposit (? Blancan and or in part Irvingtonian and Rancholabrean); I've chosen not to include this material.

General Description. Fossils were recovered from several asphalt deposits near the city of McKittrick (Jefferson 1991b). Fox-Dobbs et al. (2014) summarized the history of faunal recovery from the McKittrick area.
