Where did turtles come from? And how did they get their shells? The answers to these questions would eventually cause scientists to rethink the entire history of reptile evolution.

Thanks as always to Nobumichi Tamura for allowing us to use his wonderful paleoart : http://spinops.blogspot.com/ Additionally, a big thank you to Tyler Lyson, Luke Norton, Andrey Atuchin, and Gaberiel Bever for their images of Eunotosaurus.

Produced for PBS Digital Studios.
