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 it's DNA is completed to 100% the Edmontosaurus will live until 6 years.
