Stegosaurus was a vegetarian that lived around 156 to 140 million years ago during the late Jurassic period.

Like all Ornithischians Stegosaurus had a toothless beak for stripping tough vegetation off plants, and lots of teeth in is jaws for chewing it. Stegosaurus had two rows of triangular bony plates running down its back and spines on its tail that it could use for defence. Stegosaurus probably lived in herds grazing off low lying vegetation growing on the plains. Stegosaurus is thought to have been one of the dumbest dinosaurs having a brain the size of a walnut.

Stegosaurus means "plated lizard". It was named by Othniel Marsh in 1877. Fossils have been found in Colorado, Wyoming and Utha in the USA.
