- The Parasaurolophus got its scientific name Parasaurolophus walkeri in 1922, by William Parks.
- William Parks named the Parasaurolophus walkeri in honor of Sir Byron Edmund Walker, Chairman of the Board of Trustees of the Royal Ontario Museum.

- The holotype specimen (ROM 768) has an estimated length of 31 feet.
- The holotype specimen (ROM 768) has an estimated weight of 2.8 tons.
- Parasaurolophus was a herbivore and ate a wide variety of vegetation, some as high as 13 feet off the ground.
