Parasaurolophus ("Near Crested Lizard") is a genus of herbivorous dinosaur that lived in what is now North America during the Late Cretaceous Period about 76–65 Mllion Years Ago. It was related to Iguanodon and Edmontosaurus.

It walked both on all four legs and ran on just two. Parasaurolophus had a long crest on its head and grew to 10 meters long - medium-sized by dinosaur standards, so it lived in herds to protect it from predators such as Deinosuchus and Albertosaurus.



Parasaurolophus lived during the Late Cretaceous in North America from 76-65 million years ago, living up until the dinosaurs died out. They shaired their environments with other hadrosaurus, like Edmontosaurus, the ceratopcian dinosaurs, Ankylosaurus, and was also preyed upon by the raptor dinosaurs, Deinosuchus, and the large Tyranosaur family.


Parasaurolophus were relatively large dinosaurs, about 10 meters, over 30 feet long. Weighed in at five or six tons. The cones, or crests, on top of their heads were brightly colored and Parasaurolophus used them for display.

As another member of the hadrosaur family, a common group of dinosaurs at the end of the Late Cretaceous, Parasaurolophus spent most of their time on all four legs and ran very fast on just two legs and only ran bipedally to move fast in order to get away from danger. Like their Asian cousin Saurolophus, they had got duck bills for grinding vegetation.

Behavior Edit

Like all hadrosaurs and other herbivorous dinosaurs, Parasaurolophus lived in large herds of dozens, even hundreds of individuals.
