In the dentary from the rockshelter, toothwear again interferes, but it appears the m3 has a strong rather than a weak anterior deflection of the hypoconid as in subgenus Leucocrossuromys and a weak mesolophid as in subgenus Cynomys.
DISCUSSION--As is common in paleontological studies, the inadequacy or incompleteness of specimens together with unknown interspecific and intraspecific morphological variability of fossil taxa precludes specific identification of specimens of several genera from the rockshelter in Cimarron County (Mammuthus, Lepus, Sylvilagus, Neotoma, Cynomys, Equus, and Bison).
It preserves one extinct form (Bison antiquus occidentalis) and five extant forms (Lepus californicus, Cynomys ludovicianus, Spermophilus, Thomomys bottae, and Odocoileus hemionus; Morgan and Lucas, 2005).
