The Edmontosaurus was a hadrosaur (duck-billed dinosaur) that lived at the same time as the Tyrannosaurus rex. It was this carnivore’s preferred prey; many bite marks have been found on Edmontosaurus fossils. The mouth contains more than a thousand teeth that, like a rasp, allow it to grind foliage.
They were facultative bipeds like the Iguanodon. It could walk either on its two forelimbs or on all four limbs. Its tail made up more than half of its body and served as a counterbalance.
It was an ornithischian dinosaur with a bird-like pelvis. Scientists think that Edmontosaurus had air sacs that could inflate around the snout. They may have been used to make louder vocalizations. It lived in forested environments and in areas with a humid climate.
Baby Edmontosauruses weighed the same as a human baby at birth; they were much longer, but the tail, which made up a large part of the dinosaur’s body, was light.
According to a scan, it could have run up to 57 km/h.
