Attacks or accidents? A thread for #FossilFriday!
Several hadrosaurs have been found with serious, oval shaped injuries to the tall spines along the tops of their tail. Some paleontologists have suggested that these are from unsuccessful attacks by tyrannosaurs. But are they?1/11 The two best specimens are a Brachylophosaurus (JRF1002) and an Edmontosaurus (DMNH1493) with strikingly similar injuries. In both cases the bones had begun healing after the injury occurred, so while these may have contributed to the animals deaths they likely weren't the cause.
