Once or twice you’ve seen or heard the name Parasaurolophus being mentioned somewhere in a movie or across the street. Did you care to know what it meant? Probably it has never occurred to you that Parasaurolophus was a herbivorous and duck-billed dinosaur whose skeleton was first found in Canada in the early years of the twentieth century. Its fossils were also found in Utah and Mexico in later years. Having been extinct for quite some time, there is a good chance that several people miss important information about the dinosaur. Below are 6 Parasaurolophus facts that you should know.
1. Parasaurolophus is comprised of three species
The Northern America Parasaurolophus comprised of three species namely;
- P. tubicen
- P. cyrtocritatus
The species had different body forms. Initially, it’s was believed that a relative of the Parasaurolophus was discovered in Asia. The Asian Charonosaurus was longer and heavier than its American cousin. It was later discovered that it belonged to a different genus.
2. It had a long and tubular crest
One of the notable features of the dinosaur was its distinct crest on the head. Several tubes ran from the nostrils to the crest and back to the skull. Besides the several theories suggesting the uses of the crest, scientists recently came up with a conclusive answer to the question. Studies have shown that the dinosaur used the crests to identify one another and display their sex. In addition, it used the crest to control body temperature.
3. The dinosaur was enormously large
The Parasaurolophus was endowed with an abnormally huge body. The P. walkeri was the longest of the three species. Its length is estimated at 9.4 meters. Its skull measured 1.6 meters and weighed 2.7 tons. However, the P. tubicen had a longer skull measuring 2.0 meters. The species had strongly built upper arms and pelvic section.
4. Exhibited bipedal and quadrupedal movement
The Parasaurolophus could walk on two or four legs depending on the situation. Since it was herbivorous, it used it stood on its hind legs while reaching for vegetation as high as four meters. It ran on two legs when fleeing from an enemy and walked on the four legs when feeding on forage close to the ground. It could reach a maximum speed of 25 km/h but could not travel long distances at the speed.
5. You can listen to a clip of the dinosaur sound
Anything is possible with the technological advancement taking place in the scientific field. Towards the end of the twentieth century, a group of scientists was able to simulate the deep, resonating noise of the Parasaurolophus. This was made possible by making deep studies of the structure of dinosaur’s skull. Parasaurolophus used its crest to produce the sound by running air through the tubes at a high speed. It was a means of communicating with other members of the herd.
6. Its teeth continued to grow throughout its lifetime
The Parasaurolophus used its narrow, tough beak to cut forage from shrubs and trees, and then proceeded to grind using hundreds of small teeth. Since it used its front teeth to cut off vegetation, they got eroded away at a faster rate. However, teeth from the back would make their way forward and replace the lost teeth. The process continued throughout the lifetime of the dinosaur.
The Parasaurolophus lived in the Northern American several million years ago. With the discovery of its skeleton in the early years of the twentieth century, scientists have derived much information about the dinosaur from the fossils. The above Parasaurolophus facts will certainly give you a deeper insight into the amazing dinosaurs.
