Gnawing on #bones is classic mammalian feeding behavior, but not so much in groups that lack molars. That's what makes these theropod #dinosaur 'gnawing-like' bite marks so unexpected and cool!

The size of the marks, and the list of known predators in the area, point to either an adult dromaeosaur (raptor) or young tyrannosaur. Due to the nature of the marks and location of the bites, it may represent late-stage carcass consumption or scavenging. https://t.co/3wGOARKIWZ
