Danger! Run! The calls emitted from the crests of Parasaurolophus warned the others in the herd of the approach of predators. Running was the only natural defence for a Parasaurolophus. The dinosaur could move quickly on its two strong hindlimbs and when grazing it could crouch down on all four legs, its duck-like beak with the hundreds of tiny teeth grinding the fibrous conifers and ferns into a digestible pulp.
