The cave bear (Ursus spelaeus) is a prehistoric species of bear that lived in Europe and Asia during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum. Both the word cave and the scientific name spelaeus are used because fossils of this species were mostly found in caves.

For comparison, the manus of the spectacled bear has five digits arrayed in a shallow arc (Chaquil Cave, Peru). [ 79 ] [ 80 ] However this is potentially contradicted by possible Arctodus simus trackways from near Lakeview , Oregon, with strong toe splaying, three centrally aligned & evenly spaced toes at the front, and two almost perpendicular ...
[6] [7] Along with other large bears such as the cave bear, short-faced bears Arctodus and Arctotherium, and an extinct subspecies of the modern polar bear Ursus maritimus tyrannus, Agriotherium was among the largest known terrestrial members of Carnivora. They had longer legs and shorter faces than other bears, and were more lightly built.
Some studies have suggested the Gamssulzen Cave bear to have been herbivorous, living off vegetation with little contribution of grass. [4] Other studies proposed Ursus ingressus to have been an omnivore, with participation of terrestrial and more likely aquatic animal protein, that exceeds the participation of animal protein in the diet of the modern brown bear (Ursus arctos).

[146] [147] Another huge bear was the giant short-faced bear (Arctodus simus), with the average weight of 625 kg (1,378 lb) and the maximum estimated at 957 kg (2,110 lb). [148] There is a guess that the largest individuals of this species could reached even larger mass, up to 1,200 kg (2,600 lb). [146]

Cave bear teeth show greater wear than most modern bear species, suggesting a diet of tough materials. However, tubers and other gritty food, which cause distinctive tooth wear in modern brown bears, do not appear to have constituted a major part of cave bears' diets on the basis of dental microwear analysis.
