Parasaurolophus was a very unique looking dinosaur. It had a very prominent crest atop its head that was almost six feet in length. This hollow tube was probably used to make sounds that may have allowed it to call to others in its herd. It was one of the largest plant-eaters of the Cretaceous Period.

Parasaurolophus would have walked primarily on all four legs, but it could have stood on its hind legs to feed or defend itself and used its long tail for balance. It had a fairly long neck that would have allowed it to find food on the ground or in trees. It was a member of family of dinosaurs we refer to as duckbills, meaning it had a hard beak in the front of its mouth and hundreds of teeth in the back for chewing tough plant material. These types of plant-eaters were most likely easy prey for the large predators of this time, so it probably found safety in numbers.

The long tube that makes up the crest is connected to the nostrils and the back of the throat of this dinosaur. It may have been able to make very loud sounds that could have been heard for miles.
