''Teinurosaurus'' (meaning "extended tail lizard") is a genus of carnivorous theropod dinosaur. ''Teinurosaurus'' lived during the Late Jurassic in what is now Portugal. Only a single caudal vertebra (now destroyed) has ever been discovered, and the genus is usually considered a ''nomen dubium''. The type species is ''Teinurosaurus sauvagei''. In 1897 French paleontologist Henri-Émile Sauvage referred a tail vertebra from the Kimmeridgian of Portugal, present in the collection of the Musée Géologique du Boulonnais at Boulogne-sur-Mer in France, to ''Iguanodon prestwichii'', a herbivorous iguanodont.〔Sauvage, H.-E., 1897/1898, ''Les Vertébrés fossiles du Portugal. Contributions à l'étude des poissons et des reptiles du Jurassique et du Crétacé'', Mémoires et Communications du Service géologique du Portugal pp. 1-46〕 In 1928 Baron Franz Nopcsa recognised the fossil to be the vertebra of a theropod instead. He decided to name it as the genus ''Teinurosaurus''. The name is derived from Greek ''teinein'', "to stretch", and ''oura'', "tail", referring to the elongated form.〔Nopcsa, F., 1928, "The genera of reptiles", ''Palaeobiol.'' 1: 163-188〕 However, by a mistake of the printer, the footnote in which the new name was mentioned was not placed at the end of the section referring to the fossil but adjacent to a citation of ''Saurornithoides'' Osborn 1924, giving the false impression Nopcsa intended to rename the latter genus. After having discovered the typographical error, Nopcsa in 1929 added an addendum to the article, correcting the mistake.〔Nopcsa, F., 1929, Addendum "The genera of reptiles", ''Palaeobiol.'' 1: 201〕 In 1932 German paleontologist Friedrich von Huene again named the fossil, giving it the species name ''Caudocoelus sauvagei''. "Caudocoelus" means "hollow tail" in Latin. The specific epithet honours Sauvage.〔F. v. Huene, 1932, "Die fossile Reptil-Ordnung Saurischia, ihre Entwicklung und Geschichte", ''Monographien zur Geologie und Palaeontologie, serie 1'' 4(1-2): 1-361〕 The name ''Teinurosaurus'' was largely forgotten or not even understood to be a synonym of ''Caudocoelus'', until in 1969 John Ostrom revealed its priority. Ostrom also pointed out that Nopcsa had not provided a specific name.〔Ostrom, J.H., 1969, ''Osteology of ''Deinonychus antirrhopus'', an Unusual Theropod from the Lower Cretaceous of Montana'', Bulletin of the Peabody Museum of Natural History 30, pp. 1-165〕 In 1978 George Olshevsky was the first to combine the two names, making ''Teinurosaurus sauvagei'' (von Huene 1932) Olshevsky 1978 vide Nopcsa 1928 emend. 1929 a valid species name.〔Olshevsky, G., 1978, "The Archosaurian Taxa (excluding the Crocodylia)", In: ''Mesozoic Meanderings 1'', pp. 1-50〕 The holotype, once having the inventory number MGB 500 but later lost, was a distal caudal vertebra, 152 millimetres long. The species was by von Huene considered a member of the Coeluridae but is now generally seen as a ''nomen dubium'', Neotheropoda ''incertae sedis''. ==Notes== 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「Teinurosaurus」の詳細全文を読む スポンサード リンク
