Scientists have found an exquisitely preserved skull of a herbivorous dinosaur species in New Mexico, known for its weird head adornment.  The skull belongs to the iconic tube-crested dinosaur Parasaurolophus, which lived during the Late Cretaceous period, about 76.5 million to 73 million years ago.     Parasaurolophus were herbivorous reptiles that sported trumpet-like nasal passages which they blew air into through the so-called tube on their head.  This particular skull belonged to one particular species of the Parasaurolophus genus – Parasaurolophus cyrtocristatus.   The newly-revealed specimen would have been roughly 20 feet long (6.1 meters) and around 7.5 feet tall at the hip (2.3 metres) in its day.  Despite its extreme morphology, details of the specimen show that the crest is formed much like the crests of other, related duckbilled dinosaurs.
