in western North America.
• In terms of size, the Stegosaurus was
large and heavily built. On average, a
fully grown Stegosaurus was around
30 feet in length, 14 feet in height and
up to nearly 5 metric tons in weight.
• Although the Stegosaurus body was
large, the size of their brain was only
around the size of a dog’s.

of the Stegosaurus arose from the skin
rather than being attached to the
skeleton. The largest plates were
around 2 feet tall and 2 feet wide.
