Edmontosaurus was a large herbivorous dinosaur that lived during the Late Cretaceous period. It's name means "Edmonton lizard" after the location of its discovery (Edmonton, Alberta, Canada).

Edmontosaurus is part of the Hadrosauridae, or duckbill family of dinosaurs, who are known for their amazing teeth - or as paleontologists call it, their "dental battery." On each side of the jaw are three rows of sixty or more perfectly interlocking teeth - that's 720 per mouth, compared to thirty-two in an adult human! Not only did Edmontosaurus have a lot of teeth, but when one fell out, another from inside its jaw would take its place! Teeth like these are called "evergrowing".[1]

Edmontosaurus ate plants and had to be on constant alert for predators such as Tyrannosaurus and Dromaeosaurus. Edmontosaurus could not outrun any of the meat-eaters and had to rely on outmaneuvering them - like a crafty football player - and traveling in large herds, where there was safety in numbers. (Ibid.)

See the skull?

In the scene of The Lost World: Jurassic Park where Roland Tembo and Ajay Sidhu are looking at the baby Tyrannosaurus in the nest, you can see a skull. The skull is from a Hadrosaur and very long. Jurassic Park Legacy members long concluded that it belonged to the Genus Anatotitan, which is now classified as Edmontosaurus annectens.[2]

In Jurassic Park III, when Alan Grant and the others go into the lab, there are hadrosaur embryos seen floating in the breeding tanks that give an appearance to Edmontosaurus.

Edmontosaurus is a 3-star large herbivore featured in Jurassic Park: Operation Genesis. They live around wetland/grasslands in large herds and serve as one of the main food sources for Tyrannosaurus rex. Like the other hadrosaurs, they have a unique vocalisation, a low hooting sound. Bite marks on one fossil show that Edmontosaurus was a favourite food of T.rex in reality as well and in Jurassic Park: Operation Genesis. When it's DNA is completed to 100% the Edmontosaurus will live until 6 years and the Edmontosaurus is found along with the Pachycephalosaurus and the Triceratops in the Hell Creek Information.
