Fun Facts 

Dimetrodon is not only not a dinosaur, it’s actually more closely related to mammals,
including you and I, than it is to dinosaurs!

The high “sail” on Dimetrodon’s back was presumably used for thermoregulation (regulating
body temperature).

Dimetrodon was likely the top land predator of its time.


Dino or Not Dino?

Dinosaur or Not a Dinosaur? That is the Question...

It's not unusual to see many bizarre, extinct animals depicted as dinosaurs in book, cartoons, movies, and on TV. But many of these animals are NOT dinosaurs. So what exactly is a dinosaur?

There are many complicated, technical definitions for dinosaurs, but the most important requirements are that all dinosaurs are reptiles that lived on land and had their legs directly beneath their bodies, much like we do, and not splayed out to the sides, like modern lizards. 

That means that a lot of animals that many people consider to be dinosaurs, like mosasaurs, plesiosaurs, pterosaurs, and Dimetrodon, were definitely not dinosaurs.
