New Data on Large Brown Bear (Ursus arctos L., 1758, Ursidae, Carnivora, Mammalia) from the Pleistocene in Yakutia

Аннотация

New finds of brown bear (Ursus arctos L., 1758) fossil remains from the territory of Yakutia, namely, skulls and mandibular bones, have been investigated. The new finds are exceptionally large: most dimensions of these specimens exceed those of the present-day brown bears of Yakutia and even the maximal parameters of the largest individuals of the present-day Eurasian subspecies U. a. beringianus and U. a. piscator. Analysis of various data showed that giant brown bears had inhabited northern Yakutia during the Karginian interstadial in the Late Pleistocene.
