FeedingEditParasaurolophus was a plant eater. It had hundreds of teeth to mash up the tough plant material it ate. If a tooth fell out, a new one would quickly grow in its place. Parasaurolophus lived in herds, so while some ate, others could be on the lookout for predators such as T-Rex. Parasaurolophus could feed on two or four legs.
Parasaurolophus' most extraordinary feature was its head crest. On the outside it was a metre long, but inside, tubes looped round and round again, forming a total tube length of 2.5 metres. The function of these tubes would be similar to a trombone today - sound travels round the tubes to create a low frequency sound that can travel for miles. This sound was used for communication, such as warning the herd of an approaching predator.
