Parasaurolophus

Parasaurolophus is a genus of hadrosaur from the late-cretaceous period of North America, around seventy-six-million-years ago.

Facts
Parasaurolophus, like all hadrosaurs, can walk on either four or two-legs, and is humped on the back. The crest on its head is its best-known attribute: this crest is hollow with tunnels going through, allowing sound to amplify.

In the film
A herd of Parasaurolophus were briefly seen being stalked by Heart, with one being caught and killed by him.
