Edmontosaurus, meaning “lizard from Edmonton,” was a hadrosaurid dinosaur that lived in North America during the Maastrichtian stage of the Late Cretaceous period (71–65 million years ago). Adults could grow up to nine meters, with some species reaching thirteen meters, and weighed around 3.5 tonnes, making it one of the largest herbivorous dinosaurs of its time.

Edmontosaurus had a highly specialized feeding system, with up to sixty rows of teeth in its jaws, constantly replaced to grind tough plant material such as conifer needles, seeds, and twigs. Muscular cheek pouches helped pass food across its teeth, allowing it to feed both at ground level and from low-hanging vegetation.

Fossil impressions from Wyoming reveal scaly, leathery skin and tubercles along the neck, back, and tail, giving it a distinctive duck-like appearance. Primarily bipedal, it could also move on all fours, with forelimbs adapted for weight-bearing and hind limbs featuring strong muscles for support. Despite being slow and lacking defensive structures, Edmontosaurus relied on keen eyesight, hearing, and smell to detect predators early.
