Essay

Dimetrodon may have looked like a dinosaur but it was a far more ancient creature than that. The dinosaurs were "diapsid" reptiles while Dimetrodon was a "synapsid", a class of animals that includes mammals. Like us, Dimetrodon ("two-measure tooth") had two kinds of teeth that enabled it to both stab and "chew".

Many scientists believe its dorsal sail was used to regulate its body temperature.
