Summary

Located across a wide area of the Upper Great Plains of the United States, the Hell Creek Formation is one of the world’s premier locations for studying the Age of Dinosaurs, especially trends of evolution – and extinction – at the very end of the Mesozoic Era. In this episode, we discuss the ancient history and scientific history of the region, including some famous finds and groundbreaking research. In the news: giant ammonites, extinction beetles, baby pterosaurs, and the controversial Tetrapodophis.

0:18.8	Hell, Creek, Will.
0:20.3	Hello, Will.
0:22.5	Hello, David.
0:29.1	And welcome everybody to episode 127 of the Common Descent podcast.
0:32.6	We're talking about the Hell Creek formation this episode.
0:38.8	I'm excited for this one, because this is a site that I am well aware of existing. But I don't actually know a lot about it. I don't know many details, so I'm ready to absorb.
0:43.0	We've only ever done a handful of episodes about specific fossil localities, right?
0:48.9	We've done episodes about the gray fossil site and Nauracord, and not too long ago we did
0:52.8	Maison Creek. The Hell Creek formation is certainly one of the most famous basal localities in North America
1:00.9	and possibly the most famous, certainly for Mesozoic stuff, in the United States.
1:08.5	A lot of big important finds and a lot of big important finds and a lot of big important dinosaurs and a
1:13.0	lot of big important studies have been done or discovered at Hell Creek. Yeah, it's definitely the
1:20.1	one I hear mentioned most often. So it's, I'm sure there could be arguments about its fame
1:27.4	compared to others, but it's the one I'm most aware of.
1:30.8	So the Hell Creek Formation is a geologic locality in the Upper Great Plains here in the United States that is famous for preserving a latest Cretaceous ecosystem.
1:43.8	A very rich latest Cretaceous ecosystem. A very rich latest Cretaceous ecosystem.
1:46.7	So in this episode, we'll talk about what the Hell Creek formation is, where it is, a little bit of history of study,
1:53.4	and of course we'll talk a bunch about the kinds of things that are found there and what makes it such an important and interesting geologic place.
2:01.1	And of course, like all of our episodes, this topic was requested by listeners.
2:06.7	Specifically, the subject of Hell Creek was requested by Catherine, Zabby, Jonathan, and Colin.
2:13.4	Good requests.
