Camptosaurus

Ornithopod

Camptosaurus is a 5–7 m ornithopod of the Morrison Formation. Its teeth are leaf-shaped with a prominent primary ridge and coarse marginal denticles, and are sold from Wyoming quarries at modest prices; phalanges and vertebrae also appear. It is a reasonable entry-level Morrison ornithischian.
