''Lufengosaurus'' (, meaning "Lufeng Lizard") is a genus of massospondylid dinosaur which lived during the Early Jurassic period in what is now southwestern China.〔 ==Discovery and species== During the late 1930s geologist Bien Meinian began to uncover fossils at Shawan near Lufeng in Yunnan province. In 1938 he was joined by paleontologist Yang Zhongjian, at the time better known as "C.C. Young" in the West. In 1941, Yang named remains of a "prosauropod" ''Lufengosaurus huenei''. The generic name refers to Lufeng. The specific name honours Yang's old tutor, the German paleontologist Friedrich von Huene.〔Young, C.-C. 1940. "Preliminary notes on the Lufeng vertebrate fossils". ''Bulletin of the Geological Society of China'' 20(3-4): 235-239〕 The holotype, IVPP V15, a partial skeleton, was found in the Lower Lufeng Formation. Originally considered Triassic, this formation is now seen as dating to the Lower Jurassic (Hettangian–Sinemurian). A second species was named by Yang in 1940/1941 and fully described in 1947:〔Young, C.-C. 1947. "On ''Lufengosaurus magnus'' Young (sp. nov.) and additional finds of ''Lufengosaurus huenei'' Young". ''Palaeontologia Sinica, New Series C'' 12: 1-53〕 ''Lufengosaurus magnus'' was, as its specific name suggests ("the large one" in Latin), a significantly (up to a third in length) larger creature than ''L. huenei''. However, in the West this is often considered a junior synonym of ''Lufengosaurus huenei'', representing large individuals. About thirty major specimens have been discovered, including those of juveniles.〔Sekiya, T. & Dong, Z. 2010. "A New Juvenile Specimen of ''Lufengosaurus huenei'' Young, 1941 (Dinosauria: Prosauropoda) from the Lower Jurassic Lower Lufeng Formation of Yunnan, Southwest China". ''Acta Geologica Sinica'' 84(1): 11-21〕 In 1958 an exemplar of ''Lufengosaurus'' was the first complete dinosaur skeleton mounted in China; a commemorative postage stamp〔 of 8 yuan was issued on 15 April 1958 to celebrate the event, the first time ever a dinosaur was depicted on a stamp.〔"Lufengosaurus."

''The Age of Dinosaurs''. Publications International, LTD. p. 38. ISBN 0-7853-0443-6.〕 In 1940 Yang named another prosauropod: ''Gyposaurus sinensis''. In 1976 Peter Galton considered this species to be identical to ''Lufengosaurus''. As it is found in Bajocian stage deposits of China, this would make ''Lufengosaurus'' one of the few "prosauropod" genera to survive into the Middle Jurassic. However, the identity is today generally doubted.〔Weishampel, D.B., Dodson, P., Osmólska, H. (eds.) (2004). ''The Dinosauria, Second Edition''. University of California Press., 861 pp.〕 In 1981, Michael Cooper suggested that ''Lufengosaurus'' and ''Yunnanosaurus'' were species of the South African genus ''Massospondylus''.〔Cooper M. (1981) "The prosauropod dinosaur ''Massospondylus carinatus'' Owen from Zimbabwe: its biology, mode of life and phylogenetic significance". ''Occasional Papers Of The National Museums and Monuments of Rhodesia Series B Natural Sciences'' 6(10): 689-840〕 However, a reanalysis in 2005 by Paul Barrett and colleagues of the skull of ''Lufengosaurus huenei'' establishes it as a distinct genus separate from either ''Massospondylus'' or ''Yunnanosaurus''.〔Barrett PM, Upchurch P, Xiao-lin W. Cranial osteology of ''Lufengosaurus huenei'' Young (Dinosauria: Prosauropoda) from the Lower Jurassic of Yunnan, People’s Republic of China. Journal of Vertebrate Paleontology, 2005, 25(4):806-822 〕 In 1985 Zhao Xijin in a species list named another species: ''Lufengosaurus changduensis'', based on a specimen found in Tibet.〔Zhao X., 1985, "The Jurassic Reptilia". In: Wang, Cheng and Wang (eds.). ''The Jurassic System of China. Stratigraphy of China, Volume 11''. pp. 286-289〕 This has remained an undescribed ''nomen nudum''. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lufengosaurus」の詳細全文を読む スポンサード リンク
