The cave bear had a very broad, domed skull with a steep forehead; its stout body had long thighs, massive shins and in-turning feet, making it similar in skeletal structure to the brown bear. [15] Cave bears were comparable in size to, or larger than, the largest modern-day bears, measuring up to 2 m (6.6 ft) in length. [16]
At Labor-of-Love Cave, Nevada, both American black bears and brown bears have been found in association with Arctodus simus. A study in 1985 noted that sympatry between Arctodus and brown bears preserved in caves is rare, with only Little Box Elder Cave , Wyoming and Fairbanks II , Alaska hosting similar remains.
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.
Despite one such common name, T. floridanus is not considered a close relative of the cave bear, Ursus spelaeus, which belonged to a different genus and subfamily. Like modern spectacled bears, T. floridanus was omnivorous and likely subsisted chiefly on plant material with a majority of animal matter consumed being carrion. Similar to the ...

Cave lions also seem to have opportunistically preyed on the cubs of cave bears, [52] [57] with adult cave bears also likely being targeted at least on occasion. [34] Isotopic analysis of other European specimens suggests a diet including wild horse , woolly mammoth and cave bears for these individuals. [ 52 ]
The remains — buried in layers of soil in the collapsed cave — contained the genetic material of cave bears, hyenas and 13 bones of early humans who died some 45,000 years ago.
