Parasaurolophus belong to the Hadrosauridae family of dinosaurs. Dinosaurs from this family are known for having strange shaped skulls. The meaning of their name Parasaurolophus is ‘beside crested lizard’. They lived in the late Cretaceous period, around 74-76 million years ago. They roamed in an area of earth that is known as North America. Their fossils have been found in Alberta, Canada, Utah and New Mexico, USA.

- In 1922, William Parks was the first one to describe Parasaurolophus.
- Parasaurolophus reached approximately 30 feet in length and weighed around 3-4 tons.
- They are named this way because of the unusual crest on their head. This crest may have helped them to regulate their body temperature.

- Parasaurolophus had a large crest on its head. In adult dinosaurs, this crest could be as long as 6 feet.
- They could reach at a speed of 25 miles per hour but they cannot travel long distances at this speed.
- They had a thin but unusually tall tail.
- Parasaurolophus was a close relative of Charonosaurus.
- There are total three named species of Parasaurolophus: – P. walkeri, P. tubicen and P. Cyrtocristatus. P. Cyrtocristatus was the smallest of them.
- Each species had a unique structure of crest.
- Their teeth continued to grow throughout its lifetime.
- They probably lived in herds.
- Scientist concluded that their crest was used as a resonating chamber.
