These then, were quite sturdy animals in spite of being low in the food chain (which is apt for Hadrosaurs, as Hadrosaurus itself, means, 'Sturdy Lizard/Reptile') Although Hadrosaurs were the most sucessful large Dinosaurs at the time, they were also the most vulnerable to attack, since their only defences were hooting and fleeing.
The strange crest on the head of Parasaurolophus, is the most ornate and complex of its kind in Hadrosaurs, and Palaeontologists have argued extensively over the decades since its first discovery, as so to what real purpose or functions it may have had in life. It has been thought to have been anything from a snorkel (now disproven under closer analysis of internal structure) to a weapon (unlikely, due to relative fragility and awkardness of its position on the head) or a vocal trumpeting communication piece (more than likely)
It was a contemporary of Utahceratops, Kosmoceratops, Centrosaurus, Chasmosaurus, Pentaceratops, Ornithomimus, Gryposaurus, Kritosaurus, Corythosaurus, Teratophoneus, Gorgosaurus, Bistahieversor, Dromeosaurus, Troodon, Sauronthelestes, Alamosaurus, Edmontonia, Nodocephalosaurus, Euoplocephalus and Dyoplosaurus..
Walking with DinosaursEdit
Parasaurolophus doesn't appear in Walking with Dinosaurs.
Parasaurolophus finally had a major appearance in Prehistoric Park in episode 6 where Nigel encounters a large herd (one teenage male was killed by a female Deinosuchus). None of the Parasaurolophus are brough back to Prehistoric Park, but in the intro, two are seen in the park.
