In this episode we take a look at the actual identification of dinosaurs. What makes a species a species and how does this apply to fossils that are a hundred million years old? From there we look to how dinosaurs get their names where things can go wrong when it comes to correctly identifying them. Our special guest this time out is Professor Chris Jackson, geologist and science communicator par excellence, who wants to ask Dave a very pertinent question about how dinosaurs are actually defined and so what is, and isn't, a dinosaur.
