It’s dinosaur time again! This episode, the spotlight is on the “living tanks” of the Mesozoic, the armored ankylosaurs. These impressive creatures were covered head to tail in dazzling armor that puts most other fortified animals to shame. We’ll discuss what exactly they may have been doing with that armor and how they fit into dinosaur-filled ecosystems. Oh, and we’ll talk about those tail clubs, too.

In the news: shark-bitten whales, an early hominin skull, “killer” claws, and pterosaur poop.
