Ursus spelaeus (Pleistocene)

The cave bear (Ursus spelaeus) was a species of bear that lived in Europe during the Pleistocene and became extinct about 24,000 years ago during the Last Glacial Maximum.

Both the name "cave" and the scientific name spelaeus are because fossils of this species were mostly found in caves, showing that cave bears may have spent more time in caves than the brown bear, which uses caves only for hibernation. Consequently, in the course of time, whole layers of bones, almost entire skeletons, were found in many caves.
