*Hadrosaurus* was a duck-billed herbivore from the **Late Cretaceous period** of North America.
Known for its strong hind legs and broad, flattened snout, it likely moved in herds and may have used vocalizations to communicate.
As one of the earliest hadrosaurids described, Hadrosaurus represents a key member of the "duck-billed" dinosaurs.

3. Hatch from an **Alligator Egg** type egg
