Many times in the history of life on Earth, reptiles have returned to the oceans. There were three famous groups of marine reptiles during the Mesozoic, and in this episode, we’re discussing the last to evolve, the shortest-lived, and the greatest (in David’s opinion, anyway) of them. We’ll tell the tale of how one group of lizards evolved to dominate waters around the world during the reign of the mosasaurs.

In the news: hunting sabertooths, very strange feathers, megalodon temperature, and feathered(?) pterosaurs.
