How did the Parasaurolophus protect itself?
Its vertebrae had tall neural arches, especially on its back, which would have given it a hump-like profile in life. Like all hadrosaurids, Parasaurolophus’ tail was especially thick, and also pretty rigid. The tail would have probably been its weapon of choice if it needed to defend itself or its young.
What was the Parasaurolophus defense?
Like all other hadrosaurs, Parasaurolophus is vulnerable to predation from most carnivores, meaning that its sole defense against predators is to avoid them.
What was the Parasaurolophus crest used for?
Parasaurolophus is often hypothesized to have used its crest as a resonating chamber to produce low frequency sounds to alert other members of a group or its species. This function was originally suggested by Wiman in 1931 when he described P. tubicen.
What is special about the Parasaurolophus?
Parasaurolophus Used its Head Crest for Communication The most distinctive feature of Parasaurolophus was the long, narrow, backward-curving crest that grew out of the back of its skull.
What does a Parasaurolophus do?
Parasaurolophus is a genus of hadrosaurid (sometimes referred to as the hadrosaurs or duck-billed dinosaurs) from approximately 76.5–73 million years ago (late Cretaceous). It is a herd animal feeding on the park’s rich vegetation. The most stunning feature of the Parasaurolophus is the crest on its head.
What environment did a Parasaurolophus live in?
All three North American species of Parasaurolophus lived in the warm, lush flats between the Rocky Mountains and inland seaway that existed during the late Cretaceous. Certain species at particular times could be found in southern Alberta, Utah, and New Mexico.
Is Ankylosaurus Armor bulletproof?
These massive dinosaurs sported incredibly strong armor — bony plates that covered their backs, skulls, and even their eyes and cheeks. Though it’s an exaggeration to call the armor “bulletproof,” an Ankylosaurus could have likely survived a shot from a small pistol, he says.
What were the Ankylosaurus predators?
Natural enemies of Ankylosaurus were carnivorous dinosaurs such as Tyrannosaurus, Tarbosaurus and Deinonychus.
What type of environment did a Parasaurolophus live in?
When was the Parasaurolophus discovered?
1922
The have been found in Canada, New Mexico and Utah, and even China. Parasauropholus was first described in 1922 by William Parks from a skull and partial skeleton found in Alberta, Canada. Possible Range of The Parasaurolophus.
Where was the Parasaurolophus cyrtocristatus skull found?
Parasaurolophus cyrtocristatus was previously known from a single, partial specimen collected in New Mexico in 1923 by legendary fossil hunter Charles H. Sternberg. The new skull was discovered in 2017 in the Fossil Forest Member of the Fruitland Formation in northwestern New Mexico.
Is the Parasaurolophus still classified as a hadrosaur?
Even though its snout was far from its most prominent feature, Parasaurolophus is still classified as a hadrosaur , or duck-billed dinosaur.
Why does a Parasaurolophus have a simulated crest?
Lo and behold, the simulated crest produced a deep, resonating sound–evidence that Parasaurolophus evolved its cranial ornament in order to communicate with other members of the herd (to warn them of danger, for example, or signal sexual availability).
Are there any fossils of Parasaurolophus in Alberta?
Parasaurolophus remains are rare in Alberta, with only one other partial skull from (probably) the Dinosaur Park Formation, and three Dinosaur Park specimens lacking skulls, possibly belonging to the genus.
