Abstract


External morphological, X‑ray and tomographic study of the rodent frozen mummy from the Upper Pleistocene Yedoma deposits on the Tirekhtyakh River (tributary of the Semyulyakh River, Abyi District, Republic of Sakha (Yakutia)) showed its belonging to Lemmus sp. The radiocarbon age of the find is 41 305-41 885 cal BP. This is the first Pleistocene discovery of a frozen mummy of the representative of the genus Lemmus. In terms of body and skull size, coat color, length of the lower incisor and the structure of the molars, the specimen studied is closed to the Recent Lemmus sibiricus (Kerr, 1792). Comparison of the mitochondrial COI gene sequence with the DNA sequences presented in the GenBank database demonstrates maximum similarity with the Recent Siberian brown lemming too.
