Summary

Stegosaurus is one of the all-time most famous and recognizable dinosaurs, but it wasn’t alone! Its whole extended family, the stegosaurs, were medium- to large-sized herbivorous dinosaurs sporting an array of plates and spikes. This episode, we discuss the diversity and deep history of stegosaurs, what we know of their lifestyles, and of course the big questions: just what were they doing with that ridiculous armor? In the news: Moon impacts, bird brains, Jurassic vomit, and super-old algae.
