Cementum and dentin increment analysis and dental microwear analysis were used for the first time to study the dental remains of a giant brown bear (Ursus arctos) from the Late Pleistocene of Yakutia, Russia. Dental increment analysis showed that this bear died during the warm season (May–Sep) in the prime of its life—at the age of 15+ years. Dental microwear analysis inferred that this bear had a varied diet consisting of a wide range of plant items, varying from soft-mast during warm season to
