Dimetrodons are not true dinosaurs, but are grouped with them in popular myth. They are actually predatory synapsids (reptiles who had many mammalian traits). Technically, it is a pelycosaur (pelycosaurs had no scales, and they predated the dinosaurs. Their eggs had membranes which made them better adapted for laying and surviving on land instead of in water, like those of most modern egg-laying land animals.) They possessed spines which stuck up from their spine into the air, connected by skin, forming a huge frill or sail. This sail enabled it to regulate its temperature with strong efficiency, sunbathing to gain heat or staying in shadow to quickly bleed it off. This allowed it to operate for longer periods of time year-round. It was an apex predator, one of the largest of its day (11 feet long. Keep in mind this is during the Permian Period, long before the true dinosaurs.) They possessed a long tail and two kinds of teeth—broad teeth for shearing and sharp canines for piercing.
