Parasaurolophus. A herbivore from the Late Cretaceous Era (76-73 Million years ago). There were many fossils found in Alberta , Canada , New Mexico , and Utah , USA . The first fossil records were in 1902, but there was a lot of confusion on if the fossils were from another dinosaur that had been previously found. Once it was 1922 a man by the name of William Parks found a skull and that same early partial bone structure, in Alberta . After putting the pieces together it was proven true that the old fossil record was indeed a Parasaurolophus.
The Parasaurolophus is from the hadrosaurid family which is a very unique family of dinosaurs. Typically the dinosaurs from this group had strange shaped heads. The Parasaurolophus proves no different because it had a cranial crest which looked like a long curved tube projecting upwards and back from the skull. This could've been used for recognition of each other, loud unique sounds, and thermoregulation (control body temperature)
