New Data on the Distribution of the Small Cave Bear (Ursus ex gr. savini-rossicus) in the Urals.

The lower molar (m1) of cave bears from Late Pleistocene localities of the Urals was studied employing the methods of traditional morphometry and geometric morphometrics. On the basis of the size and shape variation of m1, the small cave bear (Ursus ex gr. savini-rossicus) was found to have been a part of the faunas from the caves Skazka, Viasher, Dynamitnaya, Chudesnitsa, and Chernye Kosti. The small cave bear presence in faunas from the Medvezhya, Makhnevskaya Ledyanaya, Asha 1, Ignat'evskaya, and Barsuchii Dol caves was confirmed as well. The species range of the small cave bear encompassed the Northern, Middle, and Southern Urals in the Late Pleistocene. The ranges of the small cave bear and cave bear (Ursus kanivetz) overlapped from the beginning (marine isotope stage 5e) to the middle (middle marine isotope stage 3) of the Late Pleistocene.
