What type of dinosaur had a nose that looked like a beak? Hadrosaurs! That is why they are often known as duck-billed dinosaurs.
Hadrosaurs were plant eaters. They moved in herds, or groups. Most ate while standing on four legs. They were able to walk and run on two legs.
Some hadrosaurs had head crests. The crests were made of a long piece of hollow bone. Hollow means having an empty space on the inside.
