Episode 74: Early Archosaurs and Teleocrater

We have a pretty good idea about how different dinosaur groups evolved, and how they are related (although anyone who has been following the recent dinosaur relationship shake-up knows this is not quite as clear as previously thought), but we don't have a good idea of how their ancestors, early dinosauromorphs and other early archosaurs, evolved. When did these groups first appear? What lead to their diversification? In this episode, we speak with (recently promoted!) Professor Richard Butler from the University of Birmingham and Academic Keeper of the Lapworth Museum of Geology about the evolution of this group, and early archosaurs in general. We also discuss a new, important species from the Middle Triassic of Tanzania described today in Nature by Nesbitt, Butler, and colleagues called Teleocrater rhadinus.
