| Abstract: | The study deals with a new sample of the mammalian fossils from the Pleistocene deposits of the Ignatievskaya Cave in Southern Urals (54°53' N, 57°46' E). Among the rodent fossils, the teeth of red squirrel (Sciurus vulgaris) and forest dormouse (Dryomys nitedula) have been identified. The enamel differentiation quotient (SDQ) of the water vole teeth matches the Arvicola terrestris species from locations of the end of Middle and Late Pleistocene (oxygen isotope stages, OIS 6 and OIS 5–2, respectively). The high SDQ value for the water vole and the presence of the squirrel and dormouse in the fauna allow dating the finding near the end of the Middle Pleistocene and beginning of the Late Pleistocene (OIS 6 and OIS 5e, respectively). The widespread open and forest landscapes were inhabited by this fauna. |
