Schleich 15011 Dimetrodon. The Dimetrodon is often mistaken for a dinosaur. But it's actually a prehistoric reptile called a Pelycosaurus. In this special Schleich version, the Dimetrodon's jaw is movable, and the tail is flexible. Schleich figurines are realistically reproduced and always to scale. All figurines are hand-painted, ensuring they always accurately reflect the real thing.
