Hadrosaurus

Hadrosaurus, live reconstruction

• North America

• Hadrosaurus foulkii

Hadrosaurus ( ancient Greek: ἁδρός, hadrós - " massive, huge, strong ' σαῦρος, sauros - " lizard " ) is a genus of bird Beck dinosaur from the Upper Cretaceous of North America. However, the genus is dubium as a noun, its validity is therefore uncertain.

Hadrosaurus is the first representative of Hadrosauridae family, whose type genus it is scientifically described. Hadrosaurus foulkii - named after its discoverer, William Parker Foulke - is the only type ( type species ) of the genus.

A 1858 salvaged Hadrosaurus was the first dinosaur in North America by the more than a few teeth were found. A file created in 1868 by Benjamin Waterhouse Hawkins skeletal reconstruction of H. foulkii was the first such reconstruction of a dinosaur. The species was declared in 1991, the state dinosaur of the U.S. state of New Jersey.

Description

Fossil evidence of Hadrosaurus found in rocks of late Cretaceous ( about 80 million years ago) near the present coast of New Jersey. Dinosaurs reached a length of approximately eight meters. He moved away as all Iguanodontia predominantly quadrupedal ( four-legged ) and moved to bipedalism ( bipedalism ) to achieve high speed. He was the first dinosaur in which the frequently encountered in this fossil animal group bipedalism was found. Like all hadrosaurs (and the bird Beck dinosaur products) Hadrosaurus was a herbivore. His dentition suggests that he fed on twigs and foliage.
