How Did Dinosaurs Get So Huge?

Viewers like you help make PBS (Thank you 😃) . Support your local PBS Member Station here: https://to.pbs.org/DonateEONS Part of why we’re so fascinated with extinct dinosaurs it’s just hard for us to believe that animals that huge actually existed. And yet, they existed! From the Jurassic to the Cretaceous Periods, creatures as tall as a five-story building were shaking the Earth. Thanks to Nathan E. Rogers, Julio Lacerda, Franz Anthony and Studio 252mya for their illustrations.
