Stunning 150-million-year-old stegosaur skull rewrites dinosaur evolution

A spectacular dinosaur discovery in Spain is giving scientists a rare new look inside the world of stegosaurs. Paleontologists uncovered the best-preserved stegosaur skull ever found in Europe, belonging to the iconic plated dinosaur Dacentrurus armatus, which roamed Earth around 150 million years ago. Because stegosaur skulls are extremely fragile and almost never survive intact, the fossil is helping researchers uncover previously unknown details about how these armored giants evolved.

Episode 170: Cariocecus bocagei

The iguanodontians were an incredibly successful group within the Cretaceous. They could reach incredible sizes, with the largest species even matching the proportions of some sauropods, and they also had an incredible palaeogeographic range, meaning that their remains are found all over the world today. In the late Jurassic, they were a lot less diverse [&hellip
