This is a between-series BONUS that was previous released to Patrons on Patreon. In it a palaeontologist makes up for Dave’s inadequacies when dealing with the ornithischians. So welcome Dr Victoria Arbour of the Royal BC Museum of Victoria, Canada to talk with Dave and Iszi about the armoured dinosaurs, the ankylosaurs. She is a world expert on this amazing and unfairly overlooked group and joins us to talk through their origins, evolution and weird features – not just the famous armour and tail clubs, but also their convoluted noses too. Victoria has published numerous papers on these animals including naming several species, first and foremost among them for Terrible Lizards listeners being Zuul, the animal that guest Ralph Attanasia (S1, E4) turned into a life-sized cake.
