Episode 112 - Caves

Subterranean passages and chambers within the Earth form eerie and incredible environments that are home to unique ecosystems of bizarre creatures and which serve as some of the most invaluable sources of fossils in the world. This episode, we discuss how caves form, what ecosystems dwell within them, and why they’re so darn important for paleontology.

In the news: pterosaur thumbs, scimitar-cat diets, counting T. rex, and ancient soil DNA.
