Summary

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.

0:51.4	Now, speaking of numbers, Will, I was thinking back over our episode topics that we have discussed,
0:57.8	and I realized it has been 48 episodes since the last time we talked about squamates. You are correct. And this is unacceptable. Listeners, our topic for this episode
1:05.0	is Mosasors. Yeah. And I'm so excited. So, Mososaurs are an ancient group of marine reptiles, one of the famous Mesozoic marine reptiles. In this episode, I will endeavor to answer the longstanding burning question, why are Mosasors the best aquatic animals
1:32.5	of all time? And I will answer this question in seven parts. And over the course of this
1:41.6	episode, we will discuss their evolution, we will discuss their biology,
1:45.1	and we'll talk about some of the really cool information that paleontologists have been able
1:50.6	to learn about them from some really cool specimens.
1:54.3	Yeah.
1:55.3	Now, I want to specify aquatic being just aquatic, not not aquatic trestri animals that
