Kelmayisaurus
''Kelmayisaurus'' is an extinct genus of carcharodontosaurid theropod dinosaur from the early Cretaceous. It was roughly 9-11 meters (30-36 feet) Its name refers to the petroleum-producing city of Karamay in the Xinjiang province of western China near where it was found.
==Discovery and species==
''Kelmayisaurus'' is known from the holotype and only specimen IVPP V 4022. It consists of a complete left dentary (lower jaw with teeth) and partial left maxilla. The specimen was found in the Lianmugin Formation of the Tugulu Group, dating to the ?Valanginian-Albian stages, around 140 to 100 million years ago. The discovery locality is near Wuerho in the Junggar Basin.〔 It was first named and described by Chinese paleontologist Dong Zhiming in 1973 and the type species is ''Kelmayisaurus petrolicus''.〔Dong, Z. (1973). "Dinosaurs from Wuerho". ''Reports of Paleontological Expedition to Sinkiang (II): Pterosaurian Fauna from Wuerho, Sinkiang. Memoirs of the Institute of Vertebrate Paleontology and Paleoanthropology, Academia Sinica'' 11: 45-52.〕 A supposed second species, K. "gigantus", was mentioned by Grady in a children book in 1993 as a gigantic vertebral column coming from a 22 m long specimen,〔Grady, 1993. The Dinosaur Project: The Story of the Greatest Dinosaur Expedition Ever Mounted. Edmonton: Ex Terra Foundation; Toronto: Macfarlane Walter & Ross. ISBN 0-921912-46-3. 261 pp.〕 but is a ''nomen nudum'' and probably does not pertain to ''Kelmayisaurus''. It may be a sauropod instead.〔http://dml.cmnh.org/2003Jul/msg00355.html〕
