‘near crested lizard’
Warm, moist climatic conditions in lowland areas.
Parasaurolophus was a hadrosaurid, part of a diverse family of Cretaceous dinosaurs known for their range of strange head structures. These lived in what is now North America and Asia. This animal is known especially for its large, elaborate head crest, which at its largest forms a long curved tube projecting upwards and back from the skull. One species, Parasaurolophus walkeri is estimated at 9.5 m long, 5 m tall and its weight is estimated at between 3 to 4 tonnes. Its skull is about 1.6 m long, including the crest.
Herbivore. It had hundreds of cheek teeth which it used to grind up its primary food source such as conifers and ferns. It used its beak to crop plant material, which was held in the jaws by a cheek-like organ, which allowed for a type of ‘chewing’ that other dinosaurs could not do.
