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.
[5] [6] Platygonus compressus had elongated limbs, a short humerus, broad and erect thoracic vertebrae and a large scapula. Therefore it has been suggested that this species may have been fleeter on foot than modern peccary species. [3] Otherwise they probably appeared very similar to their closest living relative, the Chacoan peccary.
P. balamoides has only a single reported specimen, the distal end of a right humerus (upper arm bone), that is notably of exceptional size for a felid. It was unearthed in 2012 from an underwater cave and described in 2019 by an international group of paleontologists from Mexico and Germany led by Sarah R. Stinnesbeck.

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). [5]
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.
The Tremarctinae or short-faced bears is a subfamily of Ursidae that contains one living representative, the spectacled bear (Tremarctos ornatus) of South America, and several extinct species from four genera: the Florida spectacled bear (Tremarctos floridanus), the North American giant short-faced bears Arctodus (A. pristinus and A. simus), the South American giant short-faced bear ...
