    Edmontosaurus was one of the largest members of the hadrosaur family which lived during the late Cretaceous in North America. These were large dinosaurs which grow up to 50 feet in length and weighed up to 10,000 lbs. Edmontosaurus was a herbivore who had a large bill-like snout that was able to nip and tear vegetation, and their jaws were filled with rows of large teeth used to grind vegetation. They appear to live in herds and they would be prey for Tyrannosaurus rex. Edmontosaurus had little defense when attacked by T. rex. They are believed to have good speed for their size and a herd of large adults may have been have been threatening to a T. rex. There are two species of Edmontosaurus and in the Hell Creek formation, Edmontosaurus annectens was the species present.

    Today, we find fossilized Edmontosaurus annectens teeth, unguals (claws), and bones in the Hell Creek Formation.
