Microwear and isotopic analyses on cave bear remains from Toll Cave reveal both short-term and long-term dietary habits

Dietary habits of the extinct Ursus spelaeus have always been a controversial topic in paleontological studies. In this work, we investigate carbon and nitrogen values in the bone collagen and dental microwear of U . spelaeus specimens recovered in Level 4 from Toll Cave (Moià, Catalonia, NE Iberian Peninsula). These remains have been dated to > 49,000 14 C BP. The ability of both proxies to provide data on the diet of U . spelaeus at...
