Location of Bat Cave.Age. Late Wisconsin/Holocene. >11,000 BP to present.

General Description. Cave at the southeastern edge of the San Agustín Plains. The cave apparently is wave-cut, lying a short distance above the third of six fossil beach lines of Pleistocene Lake San Agustín.

Discussion. The cave produced a long sequence of corn evolution as well as other archaeological information (Dick 1965). Most of the fauna (Scarbrough 1986; not given here) is either Holocene or not clearly Pleistocene and was excavated by W. H. Wills (1988). A radiocarbon date of 10,410 ± 110 (A-3728) was obtained from Stratum 4, top of level 17, and a date of 11,370 ± 310 from Stratum 7, level 23 (Scarbrough 1986).

Stratum 4, level 17, is arbitrarily chosen as the division between Pleistocene and Holocene, and only taxa from this level or deeper are listed below. All taxa listed are from Scarbrough (1986).
