Fossil Cave Bear Tooth – Ursus uralensis
The Cave Bear was a species of bear which lived in Europe during the Pleistocene Period and became extinct at the beginning of the Last Glacial Maximum about 27,500 years ago. In Romania, there is a cave where 140 cave bear skeletons were discovered in 1983.
Overhunting by humans has been largely dismissed as the reason for the Cave Bear's extinction because human populations at the time were too small to pose a serious threat to the cave bear's survival.
Evolution also carries teeth from modern-day black bears!
