A three-dimensional analysis of tooth-root morphology in living bears and implications for feeding behaviour in the extinct cave bear
The morphology of both crowns and tooth-roots reflects dietary specialisation in mammalian carnivores. In this article, we analyse the tooth-root morphology of maxillary teeth from CT scans of living bears ( Ursus arctos, Ursus americanus, Ursus maritimus, Ursus thibetanus, Melursus ursinus, Helarct...

In this article, we analyse the tooth-root morphology of maxillary teeth from CT scans of living bears ( Ursus arctos, Ursus americanus, Ursus maritimus, Ursus thibetanus, Melursus ursinus, Helarctos malayanus, Tremarctos ornatus and Ailuropoda melanoleuca ) in order to make inferences about the diet and feeding behaviour of the extinct cave bear ( Ursus spelaeus sensu lato ).

Our results indicate a close association between tooth-root surface area and feeding behaviour in all living bear species. Tooth-root surface area values of cave bears suggest that they relied more on vegetative matter than living brown bears ( Ursus arctos ) but subtle differences between these species/subspecies could also indicate different feeding strategies among the members of cave bear complex.
