''Nesodactylus'' was a genus of "rhamphorhynchoid" pterosaur from the middle-late Oxfordian age〔De la Fuente, M. S., & Iturralde-Vinent, M. (2001). A new pleurodiran turtle from the Jagua Formation (Oxfordian) of western Cuba. Journal Information, 75(4).〕 Upper Jurassic Jagua Formation of Pinar del Río, western Cuba. Its remains were collected but not prepared by Barnum Brown in 1918, from rocks better known for their fossils of marine life. When seven black chalkstone blocks were prepared from 1966 by Richard Lund by dissolving the substrate in acid, this revealed the remains of a pterosaur. Ned Colbert described and named the genus in 1969. The type species is ''Nesodactylus hesperius''. The genus name is derived from Greek ''nesos'', "island" and ''daktylos'', "finger", a reference to the island of Cuba and the typical wing finger of pterosaurs. The specific name means "western", from Greek ''hesperios''. The genus is based on holotype AMNH 2000, a partial skeleton including a skull fragment, numerous vertebrae from all parts of the spine and tail, zygapophyses (interpreted by Colbert as ossified tendons) on the tail, the pectoral girdle and a very deeply keeled sternum, arms and partial hands, part of the pelvis, parts of both femorae, partial metatarsals, and ribs. The specimen was disarticulated but associated and not very compressed; during the preparation from the limestone with acid, the bones were not completely removed. Colbert found ''Nesodactylus'' to have had longer wings and more robust limbs and longer legs than related ''Rhamphorhynchus'', although of a similar size and overall anatomy. He classified it as a rhamphorhynchid and more precisely as a member of the Rhamphorhynchinae. In 1977 James A. Jensen and John Ostrom by mistake referred to it as ''Nesodon'' (1977). Although there is little overlapping material with contemporaneous ''Cacibupteryx'', the two are clearly different based on details of the elbow and quadrate. At least one recent review suggests it was a rhamphorhynchine, while another does not classify it. ==References== 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「Nesodactylus」の詳細全文を読む スポンサード リンク
