Stegosaurus (meaning "roof-lizard") was a type of plant-eating dinosaur which lived in what is now western North America.

Stegosaurus lived in the Upper Jurassic period around 155 to 145 million years ago. It is one of the most easily recognized dinosaurs, with its distinctive double row of kite-shaped plates on its back, and the long spikes on its tail. The armor was necessary as it lived with such meat-eaters as Allosaurus and Ceratosaurus.
