Edmontosaurus, which translates to “lizard from Edmonton,” was a prominent hadrosaurid dinosaur inhabiting North America during the Maastrichtian stage of the Late Cretaceous, around 71–65 million years ago. Adults could grow up to nine meters, with some specimens reaching thirteen meters, and weighed roughly 3.5 tonnes, ranking it among the largest herbivorous dinosaurs of its era.

This duck-billed dinosaur featured a highly specialized feeding system, containing up to sixty rows of teeth in its jaws. These teeth were continuously replaced and worked alongside muscular cheek pouches to efficiently grind tough plant material such as twigs, conifer needles, and seeds. Flexible jaw bones enabled effective chewing, allowing Edmontosaurus to feed on both low vegetation and shrubs, showcasing its adaptability as a ground-level and low-browsing herbivore.

Fossilized skin impressions from Wyoming show scaly, leathery skin and tubercles along the neck, back, and tail, contributing to its distinctive duck-like appearance. Edmontosaurus primarily moved on its hind limbs but could also walk on all fours, with forelimbs adapted for weight-bearing. Its strong hind limbs, coupled with a low-tilted spine, supported both locomotion and ground-level feeding.

Although it lacked physical defenses, Edmontosaurus relied on keen eyesight, acute hearing, and a sharp sense of smell to detect predators. Studying this Late Cretaceous hadrosaurid provides crucial insight into the anatomy, behavior, and ecological role of duck-billed dinosaurs, highlighting their importance in North American prehistoric ecosystems.
