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 vocalization, a low hooting sound.

Its DNA is found along with the Pachycephalosaurus and the Triceratops in the Hell Creek B formation. When its DNA is completed to 100% the Edmontosaurus will live six years, the longest lifespan in the game.

Edmontosaurus can also live in harmony with any herbivore and are friends with Parasaurolophus and every other hadrosaurs in the park.
