This led to many paleontologists believing that it represented female or juvenile specimens of P.tubicen. It had the shortest and most curved crest of any species. P.cyrtocristatus is found in the Fruitland and Kaiparowits formations in Utah and New Mexico.It had a long straight crest with a more complex interior structure than other species. Found in Alberta's Dinosaur Park Formation, it had a long curved crest and is known from a very well preserved skeleton, which is only missing parts of its tail and its lower legs. The type species, P.walkeri is also the most iconic.There are so far three species of Parasaurolophus known. Like all hadrosaurs, Parasaurolophus had a toothless beak and batteries of grinding teeth at the back of its jaws. Parasaurolophus is a member of the lambeosaurinae subfamily of hadrosaurs, which were identifided by their elaborate hollow crests made of bone. For many years, it was also believed that the crest supported a soft tissue frill attached to the neck, however due to lack of any evidence this has fallen out of favour. The hollow crest had a complex structure of tubes which would have allowed the dinosaur to change its calls. The crest is now known to have been used as a display structure and a means of amplifying calls and sounds the dinosaur made to communicate with the rest of the herd. Other theories include a defensive weapon, a support structure, a temperature regulator or as a means to push dense branches out of the way. Initially it was believed to have been used as a snorkel, when hadrosaurs were assumed to be mainly aquatic animals that fed near and in rivers. The iconic crest of the Parasaurolophus has been much debated over the decades since its discovery. Royal represents the large asian speceis C.jiayinesis.Īrguably the most famous and recognisable hadrosaur, Parasaurolophus is also one of the rarer genera, with only a few good specimens found.Floral represents the short crested P.cyrtocristatus.Dusky represents the type species P.Walkeri, which possesses a long curved crest.There are three species in Prehistoric Kingdom, each one is presented as an alternative skin: They primarily move on all four legs but can rise on their back legs to reach food or run. An iconic dinosaur, Parasaurolophus is easily recognised by the long tube-shaped crest on its head.
