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

Appearance Edit

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 Edit

Dinosaur IslandEdit

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