This enormous dinosaur possessed an enormous 'sail' of skin, supported by spines, on its back. Many scientists believe it was a natural air conditioner that regulated the animal's temperature in some way. Flesh-eating Dimetrodon lived in Texas, had a large skull and jaws, and his teeth (two separate sets) were as sharp as daggers. * Source: back of card
