Age. Late Pleistocene.
General Description. Smartt et al. 1990: North end of Mesa del Oro. One of many caves of the Pronoun Cave Complex. The mesa is made up of early Pleistocene travertine deposits; most of caves are partially closed fissures formed by settling of the travertine blocks.
Discussion. Bighorn sheep fossils were "on the underside of a clogged fissure approximately 15 meters below the surface and on the cave floor directly beneath it" (Smartt et al. 1990:107). Measurements are given of various fossil and modern specimens in Smartt et al. 1990.
Fauna.
Ovis canadensis catclawensis—Catclaw Bighorn Sheep (Smartt et al. 1990)
Literature. Smartt et al. 1990.
