Diplocaulus is an extinct genus of amphibians from the Permian period of North America. Diplocaulus had a stocky, Salamander-like body, but was relatively large, reaching up to 1 m  in length. Its most distinctive features were the long protrusions on the sides of its Skull giving the head a boomerang shape. Judging from its weak limbs and relatively short tail, it is presumed to have swum with an up-and-down movement of its body, similar to modern Cetacea.

The wide head could have acted like a Hydrofoil, helping the creature glide through the water. Another possibility is that the shape was defensive, since even a large predator would have a hard time trying to swallow a creature with such a wide head. Rare trace fossils of Diplocaulus-like amphibians show that the tips of the boomerang-shaped head were connected to the body by flaps of skin. The diplocaulus eats fish, small crustaceans, and occasionally tadpoles of other amphibians.
