Longtime listeners will be familiar with the fact that Dave has spent a lot of time looking at and working on various bites marks on dinosaur bones left by the carnivorous theropods. These can tell us an enormous amount about who was doing what to whom and what it can mean for the ecology and behaviour of both the herbivores that were bitten and the carnivores that bit them. However, to date work on this for dinosaurs has almost exclusively focused on the tyrannosaurs with their tendency to bite on bones. But they weren’t the only ones doing this. As Dave explains to Iszi in this episode, he’s got a big new paper out with a plethora of authors assessing what was going on in the famous Morrison Formation that was teeming with giant sauropods but had plenty of theropods around too. What were they up to and can we learn more about their biology from a few bites?
