Scientifically accurate paleoart of Parasaurolophus, a herbivore Hadrosauridae dinosaur from the Campanian of the Late Cretaceous (about 76.5–73 million years ago). A long, hollow, tube-shaped crest curving backward from the top of the head well past the neck. Reference: Parasaurolophus is a genus of hadrosaurid "duck-billed" dinosaur that lived in what is now western North America and possibly Asia during the Late Cretaceous period, about 76.5–73 million years ago. It was a large herbivore that could reach over 9 metres (30 ft) long and weigh over 5 metric tons, and were able to move as a biped and a quadruped. Three species are universally recognized: P. walkeri, P. tubicen, and the short-crested P. cyrtocristatus. Anatomy: a broad, flat, duck-like toothless beak; walking on all fours with the front hands forming small hoof-like pads, tail held straight out off the ground; skin of small pebbly scales. Full body in side view, whole animal visible, standing in a Late Cretaceous coastal floodplain like the Dinosaur Park Formation of Alberta, with conifers, ferns and early flowering plants by a river, no grass. Natural history museum illustration style, realistic textures and natural daylight, muted natural colors. No text, no labels, no humans, no modern objects.
