The Dimetrodon is often
referred to as a dinosaur. However, it is a primeval reptile, a
so-called Pelycosaurus. The sail on its back was made of skin and bones,
helping it to warm itself quicker in the sun. If it wanted to cool
down, it positioned the sail parallel to the sun's rays.
Fun Fact: The Dimetrodon was an excellent hunter with extremely sharp teeth.
