<Editor's Note: Skip to 13 minutes in if you only want to get to the science. I didn't have the heart to cut the intro down> In this episode, we eventually get to discussing patterns of extinction selectivity in mammals during two major extinctions (the end Cretaceous and the modern biodiversity crisis). Also, James discusses delicious ways to end the world, Curt details the Lord of the Footballs, and Amanda really would like to know WHEN we're going to start discussing the papers.

The gang discusses two papers about archosaur heads, one of which is actually about archosaurs with big heads. Also, Amanda's cat gets revenge for the podcast thumbnail, James wants to be a super villain, Curt decides to drink, and we all design better dinosaurs. Also, this cockatoo gif is a thing that should be known and celebrated. http://i.imgur.com/mZEnTJc.mp4 Midi music from freemidi.org References: Gates, Terry A., Chris Organ, and Lindsay E. Zanno.
