The Crest

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.
