Hadrosaurus

Hadrosaurs, or duck-billed dinosaurs, were a diverse group of large, herbivorous ornithischian dinosaurs that thrived during the Late Cretaceous Period, known for their broad, duck-like beaks and complex, tooth-battery chewing mechanisms. Often living in herds, they were dominant herbivores across North America, Asia, and Europe, ranging from 30 to over 50 feet in length.
