Its single known forelimb was relatively short for a hadrosaurid, with a short but wide shoulder blade. Its weight is estimated at 2.5 tonnes (2.7 tons). tubicen is over 2.0 meters (6.6 ft) long, indicating a larger animal. Its skull is about 1.6 meters (5.2 ft) long, including the crest, whereas the type skull of P. walkeri is estimated at 9.5 meters (31 ft). 4.2.2 Rejected hypotheses about functionДЄs is the case with most dinosaurs, the skeleton of Parasaurolophus is incompletely known.4.2.1 Differences between species and growth stages.It is one of the rarer duckbills, being known from only a handful of good specimens. The crest has been much discussed by scientists the consensus is that major functions included visual recognition of both species and sex, acoustic resonance, and thermoregulation. Charonosaurus from China, which may have been its closest relative, had a similar skull and potentially a similar crest. This genus is known for its large, elaborate cranial crest, which at its largest forms a long curved tube projecting upwards and back from the skull. Parasaurolophus is a hadrosaurid, part of a diverse family of Cretaceous dinosaurs known for their range of bizarre head adornments. It was first described in 1922 by William Parks from a skull and partial skeleton in Alberta. Remains are known from Alberta, Canada, and New Mexico and Utah, USA. It was a herbivore that walked both as a biped and a quadruped.
