Genus information

Parasaurolophus was a large hadrosaur that lived during the Late Cretaceous period of North America. It had a very distinct skull having a large crest on top of its head, reaching as big as 1.6 meters in length! Many theories suggest the use of this crest, ranging from attracting mates to using it for thermoregulation. The most famous theory is that it was used as a boombox; calls of Parasaurolophus would have been amplified through the crest, which contained tubes. It was able to switch between postures meaning that is was able to graze on four limbs but also to browse on larger bushes and trees while standing on its hind limbs.
