PBS Member Stations rely on viewers like you. To support your local station, go to http://to.pbs.org/DonateEons ↓ More info below ↓ If you take it as a given that extinct dinosaurs were all weird and wonderful, then you gotta at least consider that Stegosaurus was one of the weirdest and most wonderful. Thanks to Julio Lacerda and Studio 252mya for the stegosaurus illustrations. You can find more of Julio s work here: https://252mya.com/gallery/julio-lacerda Produced for PBS Digital Studios.
