The steppe brown bear (Ursus arctos priscus) is a disputed extinct subspecies of brown bear that lived in Eurasia during either the Pleistocene or the early Holocene epochs, but its geological age is uncertain.[1] Fossils of the bear have been found in various caves in Slovakia, particularly those of Vazec, Vyvieranie, Lisková, Kupcovie Izbicka, and Okno.[2] It is argued that the subspecies should be rendered invalid, as its geological age is unclear and "its skull is identical to modern U. arctos."[3][1]

Description

Adult males in average would have weighed 700–800 kg (1,500–1,800 lb), with the largest individuals weighing up to 1,000 kg (2,200 lb).[4] It was more carnivorous than a modern brown bear, consuming 50 kg (110 lb) of meat per day.[4]
