Cave bear tooth
Cave bears, the best known being 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, hence the name. Better than renaming brown bears Outside bears. Most of these teeth will be molars, and from Ursus ingressus, slightly bigger than U.spelaeus. They were found near Mixnitz in Austria and date to at least 30,000 years ago.
