Dimetrodon is a reptile which lived millions of years before Tyrannosaurus set foot on North America and Asia. It is sometimes mistaken for a mammal because it is a Synapsid.

Appearance

Like modern lizards, Dimetrodon walked on four legs. It had a large sail, which is thought to be used to cool and warm itself.

Nativity

Dinosaur Island

Only one Dimetrodon has been spotted on Dinosaur Island, which lived on the North side.
