Cave bear tooth
Cave bears, Ursus spelaeus, lived across almost all of Europe in the Pleistocene, dying out around 27,000 years ago. They were similar to brown bears, though on average a little larger. These teeth were found in huge cave systems, alongside skeletal material. It's thought they spent longer in caves than their surviving relatives. Most of these teeth will be molars. They were found in the Carpathian Mountains in Romania and date to around 27,000 years ago.
