Exploring dietary adaptations in Ursus minimus: a 3D geometric morphometric analysis of the mandible
Boreas, Volume 55, Issue 2, Page 443-453, April 2026.Using 3D geometric morphometrics, the dietary adaptations of the extinct Auvergne bear (Ursus minimus) are analysed. Its mandibular morphology aligns more closely with omnivorous rather than insectivorous bears, challenging current ideas. The extinct bear Ursus minimus, which lived in Europe during the Pliocene and possibly Early Pleistocene, is ...
