Dimetrodon, A Unique Reptile
Dimetrodon was an extraordinary Pelycosaur from the Permian Period. The reptile ranged in size from a small lizard to a large rhino, with 3 meters being the longest skeleton found. This fierce predator was one of the first land reptiles to prey on other land animals its own size.
Dimetrodon, often mistaken for a dinosaur, is most remembered for the large sail on its back. It was originally theorized that the sail was used to help Dimetrodon swim, much like the sail on a sail boat helps to move a boat through water. This theory was not taken seriously by many paleontologists, and it was not long before the widely excepted theory of temperature regulation came to the front.
