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.
采用传统形态计量学和几何形态计量学的方法，对晚更新世乌拉尔地区洞穴熊的下臼齿（m1）进行了研究。根据 m1 的大小和形状变化，发现小洞穴熊（Ursus ex gr. savini-rossicus）是来自 Skazka、Viasher、Dynamitnaya、Chudesnitsa 和 Chernye Kosti 洞穴的动物群的一部分。在 Medvezhya、Makhnevskaya Ledyanaya、Asha 1、Ignat'evskaya 和 Barsuchii Dol 洞穴的动物群中也确认存在小洞穴熊。小洞穴熊的分布范围涵盖了晚更新世的北、中、南乌拉尔地区。小洞穴熊和洞穴熊（Ursus kanivetz）的分布范围从晚更新世开始（海洋同位素阶段 5e）到中期（中海洋同位素阶段 3）重叠。
