Dinosaur jaws and feeding with Ali Nabavizadeh

We started with theropod feeding but what about the herbivores? This week we’re joined by Ali Nabavizadeh who specialises in the jaws and teeth of the ornithischian dinosaurs and how these work and how this plays into their feeding ecology. This gives Dave ample opportunity to ask vexing questions about their jaws and elicit the same response he gives whenever asked about T. rex being a scavenger, but it does mean that Ali talks about how the hadrosaur dental battery works, how similar they are to ceratopsians and whether or not these animals have cheeks.

TLS8E06 Biomechanics of Dinosaur Motion

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.
