walkeri, showing the pathologic v-shaped notch It is one of the rarer hadrosaurids, known from only a handful of good specimens.ĭiscovery and naming Holotype specimen of P. Visual recognition of both species and sex, acoustic resonance, and thermoregulation have been proposed as functional explanations for the crest. Charonosaurus from China, which may have been its closest relative, had a similar skull and a potentially similar crest. This genus is known for its large, elaborate cranial crest, which forms a long curved tube projecting upwards and back from the skull in its largest form. Parasaurolophus was a hadrosaurid, part of a diverse family of large Late Cretaceous ornithopods that are known for their range of bizarre head adornments, which were likely used for communication and increased hearing. The genus was first described in 1922 by William Parks from a skull and partial skeleton found in Alberta. Remains are known from Alberta, New Mexico, and Utah, as well as possibly Heilongjiang if Charonosaurus is in fact part of the genus. jiayinensis, has been proposed, although it is more commonly placed in the separate genus Charonosaurus.
Three species are universally recognized: P. It was a large herbivore that could reach over 9 metres (30 ft) long and weigh over 5 metric tons (5.5 short tons), and were able to move as a biped and a quadruped. Parasaurolophus ( / ˌ p ær ə s ɔː ˈ r ɒ l ə f ə s, - ˌ s ɔːr ə ˈ l oʊ f ə s/ meaning "near crested lizard" in reference to Saurolophus) is a genus of hadrosaurid "duck-billed" dinosaur that lived in what is now western North America and possibly Asia during the Late Cretaceous period, about 76.5–73 million years ago.
