This is an area we have definitely covered before but it’s one of perennial interest and keeps coming round with new studies, how can we tell what ancient animals were doing with weird features. More specifically, how do claims that this feather, or sail, or frill, or claw were used as a display feature stack up? Can we really work out what dinosaurs are doing with features like this and how can we test such ideas with such limited data when they’ve been gone for 65 million years? Well happily Dave is going to talk through some more of it again, with a side dabble into another bit of dinosaur behaviour and looking at predation vs scavenging.
