The differences are in the details: Special 3D shape analyses of the jaws and dentitions of cave bears and brown bears living at the same time from the fossil site in the caves of Goyet in Belgium show their clearly different food spectrum. In contrast, the diet of brown bears living around 30,000 years ago differs only slightly from that of their North American relatives still living today. SNSB zoologist Anneke van Heteren has now published her comparative study together with a colleague from the Royal Belgian Institute of Natural Sciences (RBINS) in the scientific journal Boreas.
