Parasaurolophus

phylum	Chordata	Parasaurolophus is a genus of ornithopod dinosaur that lived in what is now North America during the Late Cretaceous Period, about 76.5–73 million years ago. It was a herbivore that walked both as a biped and a quadruped. The genus was first described in 1922 by William Parks from a skull and partial skeleton found in Alberta. This genus is known for its large, elaborate cranial crest, which at its largest forms a long curved tube projecting upwards and back from the skull. For more information, visit the Wikipedia entry.
