-like grasslands of Eastern Beringia. This species is known from numerous teeth and bones, and one partial carcass discovered in 1993, that yielded a radiocarbon date of 26,280 ± 210 years BP. The carcass consisted of a large part of the hide, a few tailbones, one lower leg, and some intestine. The hide retained some long blondish mane and tail hairs, coarse whitish upper body hairs, and dark brown hairs on the lower leg.
Large numbers of teeth of this species have been found in archaeological sites in the region.
