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.
