Although we looked at some biomechanical work earlier this series, this time we get into the real depths of how dinosaurs moved. John Hutchinson joins us with tales of galloping crocodiles and white dots on elephants in an effort to understand how these animals move as part of his work on dinosaur locomotion. We talk about how Jurassic Park cheated to make the T. rex look faster and just how you can build a model of such huge animals from their bones and how reliable such an exercise really is. We also return to the subject of disability in science and look at how John’s work has been affected by epilepsy over the last few years.    Links: John on Twitter: https://twitter.com/JohnRHutchinson John’s Blog: https://whatsinjohnsfreezer.com Our Twitters  @iszi_lawrence and @dave_hone Please support us on Patreon: www.patreon.com/terriblelizards
