Dimetrodon: Not a Dinosaur



Why Dimetrodon is not a dinosaur:

They lived during the Permian time period, 280-245 million years ago, way before the dinosaurs.

Dimetrodon was a pelycosaur, a mammal-like reptile.

Humans have more in common with dimetrodons than dinosaurs.

Other facts:

Pronounced Die-met-roe-don

Lived in Europe and North America.

Was a Carnivore.

Had a large sail on it's back, probably to catch heat to warm itself up.

Walked on four legs that stuck out to the side.
