The current paper describes material from Medvezhyi Klyk Cave Late Pleistocene–Holocene deposits that represented mostly by isolated teeth. The morphology and size variation of the first lower teeth (n = 542) were studied. There are Alexandromys fortis, A. cf. maximowiczii, A. cf. oeconomus, A. cf. mongolicus determined in the material. We could not determine the taxa due to uncertainty in a spatial variation of the species ranges during Late Pleistocene and Holocene, a broad variety of the m1 anteroconid shape among medium-sized species of voles, and supposed presence “archaic” and “deviant” morphotypes of m1. Geometric morphometrics methods were shown the broad variety of the m1 anteroconid shape without strict species-relation, i.e., each tooth shows proper anteroconid shape, which can repeat within limits in populations in and among species.
