Hadrosaurus was a genus of hadrosaurid dinosaurs that lived in North America during the Late Cretaceous period, around 80 to 78 million years ago. This duck-billed herbivorous dinosaur weighed between 2 and 4 tons and primarily moved on all fours, though it could rise onto its hind limbs to reach tall plants or flee predators. Its versatile locomotion made it a key member of prehistoric ecosystems, enabling it to access a wide range of vegetation.

A defining characteristic of Hadrosaurus was its complex dental battery, with up to 1,400 teeth arranged for efficient grinding of tough plant material. These specialized teeth allowed Hadrosaurus to thrive as a major herbivorous dinosaur in Late Cretaceous forests and floodplains. Its forelimbs, although less powerful than the hind limbs, assisted in standing, movement, and foraging, giving this dinosaur remarkable adaptability for feeding and locomotion.

Anatomical similarities with contemporaries like Kritosaurus and later hadrosaurids such as Edmontosaurus highlight evolutionary trends among North American herbivorous dinosaurs, including limb structure, dental specialization, and feeding strategies. The duck-billed snout, adaptive limbs, and specialized teeth of Hadrosaurus exemplify the sophisticated anatomy of hadrosaurid dinosaurs, making it one of the most significant Late Cretaceous dinosaurs in North America.

Studying Hadrosaurus offers valuable insight into the diversity, feeding strategies, and evolutionary success of herbivorous dinosaurs, and it remains a key genus for understanding the ecological dynamics of prehistoric North American dinosaur communities.
