Description

Parasaurolophus walkeri (Parks 1922)

Ornithopoda

Ankylloplexia

Hadrosauridae

Lambeosaurinae

Parasaurolophus

P. walkeri

Length: 9.5 meters (33 feet)

Height: 4.5 meters (15 feet) at the hip

Weight: 2.5 tonnes (2.8 short tons)

Time: 76.5-74.5 MYA

Habitat: The coastal floodplains of the Dinosaur Park Formation, Alberta

Niche: Although P. walkeri existed with several other large Hadrosaurs, all seemingly occupying the same niche, it is likely that they occupied similar niches (such as one eating from the top of trees, while the other eats from the bottom) in a striking example of niche partitioning.

Predators: As hatchlings and young juveniles P. walkeri were prone to predation by the Maniraptors Saurornitholestes, Dromaeosaurus, and Troodon. Juveniles and adults were the prey of the Alberosaurine Tyrannosaurid Gorgosaurus, and some of the last individuals may have prey preyed upon by the Tyrannosaurine Dasplateosaurus.

Locomotion:
 Like other hadrosaurs, P. walkeri was likely a facultative biped, although there is no reason to think that bipedal locomotion is faster. It most likely only reared on its hind legs to get a better view or reach higher vegetation. Parasaurolophus could run at an estimated 32 kph (20 mph) when at its full speed.

Extinction: Due to several factors, such as competition and climate change, P. walkeri went extinct around 74.5 MYA.

This my interpretation of Parasaurolophus walkeri. Note the strands of feathers across the body. That is how I interpret large ornithopod feathers. Thanks to randomdinos for letting me use his description structure.
