In this episode we finally fulfil a promise from before and talk more about the physiology dinosaurs – how 'hot' or 'cold' they were and what that might mean for their levels of activity, growth, behaviour and even where they could live given local climates. It's a horribly complex subject and so come and listen to us grossly oversimplify things and not make things as clear as we'd like. Also on this show we end up at the end of the digestive system as our guest, the Skep-Chick herself, Rebecca Watson asks about the second most famous bit of Jurassic Park and just how much waste would be coming out of a dinosaur. Don't say we never tackle the critical questions.
