Parasaurolophus had a long, curved tube on top of its head that looked like a horn. Scientists think it could blow air through this tube to make loud sounds, almost like a trumpet! This helped it talk to other dinosaurs in its group.
Parasaurolophus was a plant eater that could walk on two legs or four legs. It had a flat beak like a duck, so it is called a duck-billed dinosaur. Parasaurolophus lived in big herds to stay safe. It was a fast runner and could get away quickly from scary meat eaters.
