Dimetrodon is often confused with dinosaurs or their period, while in truth they have been extinct for 40 million years before the first dinosaur walked in the Triassic period.
Dimetrodon was a herbivore, living in swampy areas, it had a large head and mouth, large and strong jaw, as well as two types of teeth – sharp caniniforms and incisor teeth. It used to eat other pelycosaurs, insects and other mammals.
It could rise from its cold and lazy habitat much earlier than the dawn than pelycosaurs ‘without the sail’, then catch them and eat them.
