This dino had an amazing sail coming out of its back. The sail was made from spike shaped bones, joined together by a layer of skin.

Scientists are not sure what the sail was for. It may have been used to control its body temperature. By turning the sail to the sun it could have warmed its blood faster than other cold-blooded reptiles.
