Summary

252 million years ago, the Earth experienced what might be the worst extinction event of all time, so dramatic that it brought an end to the entire Paleozoic Era, that it resulted in the rise of entirely new types of ecosystems, and that it has come to be known as “The Great Dying.” This episode, we discuss the tragedy, the chaos, and the aftermath of the Permian Extinction. In the news: the oldest animal, giant elephant birds, mammal jaw evolution, and one really big tree.
