Extinct otter-like ‘marine bear’ might have had a bite like a saber-toothed cat

New research suggests that the feeding strategy of Kolponomos, an enigmatic shell-crushing marine predator that lived about 20 million years ago, was strangely similar to a very different kind of carnivore: the saber-toothed cat Smilodon. Scientists have shown that even though the two extinct predators likely contrasted greatly in food preference and environment, they shared similar engineering in jaw structure.
