The most recognizable aspect of hadrosaur anatomy is the flattened and laterally stretched rostral bones, which gives the distinct duck-bill look. Some members of the hadrosaurs also had massive crests on their heads, probably for display.
How did Parasaurolophus defend 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.

The hadrosaur coprolites had more than just plants and decayed wood, though. They also contained bits of crab shell! And it wasn’t only 1 coprolite that had crab shell in it. As the dinosaurs munched away on the wood, they’d eat the crabs as well, providing a good source of protein.

How old is the hadrosaur?

What are the predators of a Parasaurolophus?
Further south and the slightly shorter snouted tyrannosaurs such as Bistahieversor and Teratophoneus were the main threats to the more southern species of Parasaurolophus. Smaller predators however should not be discounted as threats, especially against smaller juveniles of Parasaurolophus.
How big is a hadrosaurus?
What kind of cancer did Hadrosaurus have?
Evidence of tumors, including hemangiomas, desmoplastic fibroma, metastatic cancer, and osteoblastoma were discovered in specimens of Hadrosaurus by analyzing dinosaur vertebrae using computerized tomography and fluoroscope screening. Several other hadrosaurids, including Brachylophosaurus, Edmontosaurus, and Gilmoreosaurus, also tested positive.
Where was the Hadrosaurus holotype found?
The holotype of Hadrosaurus was found in marine sediments, which suggests the skeleton was transported by a river and then deposited in the Cretaceous sea. The Hadrosaurus remains all persist to the Woodbury Formation.
Why is Hadrosaurus considered a nomen dubium?
Despite the fact that the family Hadrosauridae has Hadrosaurus as its type genus, the skeleton lacks a skull and was long viewed as too incomplete to compare to other hadrosaurs for classification purposes, leading most scientists to consider it a nomen dubium, or dubious name.
How did Hadrosaurus foulkii get its name?
Foulke and Leidy studied the fossils together and, in 1858, Leidy formally described and named Hadrosaurus foulkii in honor of his collaborator.
