An interview about Marine Reptiles with Keirsten Formso @formophology. To get more free bonus content FIRST become a Terrible Lizards Patron on patreon.com/terriblelizards In the third series of Terrible Lizards we finally edged away from dinosaurs to cover pterosaurs, but in the Mesozoic, there were far more reptiles in the sea than in the air so we really need to do them too. Happily to this end we can welcome Kiersten Formoso from the University of Southern California who is working on her PhD about the transition back to the water by various reptiles from the time of the dinosaurs. Over the course of this bonus episode we look at the rise and fall of various different groups that took to the water and the evolutionary changes that occurred to them as they adapted to a watery way of life. So sit back and enjoy an hour of live bearing giant dolphin-mimics and all kinds of others.    Links: Kiersten’s webpage with links to all her projects: https://www.formorphology.com    Photos taken at the Carnegie Museum of some of the groups discussed in the pod: https://archosaurmusings.wordpress.com/2011/12/12/western-interior-seaway/
