Mosasaurs Unleashed: Lords of the Late Cretaceous Seas

About this episode

We explore Mosasaurus, the apex marine lizards that ruled 94–66 million years ago. Learn how a stiff body and a powerful crescent tail propelled shark-like bursts, why double-hinged jaws and flexible skulls let them swallow large prey, and the surprising evidence for endothermy and live birth. We also trace their dramatic extinction at the K–Pg boundary—preserved in a Chicxulub tsunami deposit in Missouri—and what their rise and fall reveals about ancient oceans.
