DescriptionUnquestionably the ROM’s most famous dinosaur, this skeleton is the worlds best preserved specimen of Parasaurolophus, a large-crested, duck-billed hadrosaur. Parasaurolophus is characterized by its spectacular tubular crest that extends over a metre beyond the top of its skull. The hollow crests may have been used as resonating chambers for calling to one another. Differences in the size and shape of crests probably aided the duck-billed dinosaurs, or hadrosaurs, to recognize their own species.
