The cave bear was an Ice Age beast of prey. It inhabited the region from the Iberian Peninsula to the Caucasus. In the territory of Slovenia, it was a very common resident, the fact that has been corroborated by the large quantities of its bones found in numerous caves. As far as its size is concerned, it can be compared with a grizzly bear and even a polar bear, which is the largest currently living animal. It also differed from the brown bear in longer forelimbs than the hind limbs, a more robust skull with a strong parietal suture with a ridge, as well as long and powerful canines and strong other front teeth as well. It was an omnivore, although it fed predominantly on plants. Karst caves were used by cave bears as their wintering grounds, while in the summer months they cooled off in them. As far as their lifestyle is concerned, they resemble particularly the modern American grizzly bear. They became extinct probably due to climate change at the end of the Ice Age. The specimen displayed in the museum is composed of remains from multiple animals. They were donated to the museum by Henrik Freyer and Simon Robič and were found in various caves.
