Welcome to the jungle, we've got giant snakes - with Dr. David Polly

On today's episode of Earth on the Rocks we have Dr. David Polly, a vertebrate paleontologist interested in how past changes (geologically, climatically, environmentally) have affected life and how life may have responded or adapted in turn. Learn about sampling of fossils (both in the field and from museums), what the early internet was like and David's experience at the front lines of it, the giant fossil snake Titanoboa, national monuments and their vital role in paleontology (and how that resulted in David being called to Congress to testify), and learning Finnish through reading The Hobbit.
