Diplocaulus



Diplocaulus (meaning “double stalk”) was not a dinosaur, but an early amphibian. It lived from the Late Carboniferous to Permian periods of North America and Africa. It was distinguished by its boomerang-shaped head which was formed by two elongated bones at the back of the head. It had four short legs, and a short, flattened tail. It was about 3 feet (1 m) long.
