    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. The common and scientific name for the species comes from their remains having been found largely in caves. This reflects the views of experts that cave bears spent more time in caves than the brown bear, fre
