New Data on the Pleistocene Mammoth Fauna from the Territory of the Lena Pillars Nature Park (Middle Lena River, Yakutia)

This paper presents data on new finds of remains of Mammoth fauna mammals in the Middle Lena River basin (Lena Pillars Nature Park (Yakutia) and adjacent areas). Based on these data, a list of the main localities for large mammal species in this region was compiled. Eleven species of large mammals are identified, among which, the cave lion Panthera spelaea is reported for the first time for this region. A series of new radiocarbon dates allows us to conclude that there was a mass burial of Neopleistocene mammalian remains in this region during the Karginian interstadial (60 (55)–24 kyr ago, MIS-3). The radiocarbon dates obtained and species composition are consistent with the data that the Karginian interstadial was the most favorable for the distribution of the Mammoth fauna in the territory of Yakutia. The study results show that the ecological distribution of Ovis nivicola in the Late Pleistocene differs from its present-day habitat area.
