"Nurosaurus" (pronounced (U.S.) Nur - o - Saw - rus, meaning "Nur lizard") is the informal name for a genus of sauropod dinosaur from the Cretaceous of Inner Mongolia, China. It is known from a partial skeleton that has often been seen in traveling exhibitions under various misspellings. "Nurosaurus" had a length of 25 meters (80 ft), a height of 8 meters (25 ft), and a weight of 22.7 tonnes (25 tons). The proposed binomial name is "Nurosaurus qaganensis" (Dong, 1992).

[edit] Location

"Nurosaurus" was one of the largest Chinese long-necked plant eaters. It may have been related to the North American Camarasaurus. This is seen because "Nurosaurus" has as a similar head and body shape. Photographs also show it had similarly-split neural spines on its back vertebrae.
