Parasaurolophus (P. walkeri `Nearly saurolophus ´) is a species of browsing herbivorous hadrosaurid dinosaur that lived during the Campanian and Maastrichtian of the Late Cretaceous period, approximately 76 to 73 million years ago. It is known for its distinctive tube-shaped crest, which extends from the back of its skull and curves back over its neck.
The body of Parasaurolophus walkeri was around 10 meters long and weighed around 2.5 tons. It had a long, narrow head with a toothless jaw at the front and a battery of teeth at the back of its mouth for grinding its food. Its legs were long and slender, suggesting that it could run at high speeds if necessary.
The most notable feature of Parasaurolophus walkeri is its crest, which was around 1.5 meters long in adults and made of hollow bone. The crest is thought to have had multiple functions, including amplifying sound for communication, regulating body temperature, and sexual attraction.
The crest of Parasaurolophus walkeri had a particularly distinctive shape, resembling a trumpet pipe. The upper part of the crest curved backwards, while the lower part curved forward. The crest is thought to have produced sounds similar to a horn or trumpet when the dinosaur made vocal noises.
