The evolution of mineralized tissues is responsible not only for the incredible success and diversity of vertebrate animals, but also for their extraordinarily informative fossil record. This episode, we explore the detailed anatomy of bones and their deep evolutionary history, we touch on some of the ways they’re important for paleontology, and we take some time to discuss the secrets that can be found inside of ancient bones.

In the news: croc vs pterosaur, hominin diets, ears and gills, and reptile food.
