''Willinakaqe'' is an extinct genus of saurolophine hadrosaurid dinosaur which lived during the late Cretaceous (late Campanian-early Maastrichtian stage) of the Río Negro Province of southern Argentina. ''Willinakaqe'' is known from several disarticulated specimens, among them juvenile and adult individuals found at the Salitral Moreno site of the Lower Member of the Allen Formation. The holotype is MPCA-Pv SM 8, a right premaxilla. A second site in the Malvinas Argentinas Partido has rendered additional specimens. Together the material represents the majority of the skeleton.〔 Some of the fossils were previously discussed in the literature as potentially representing a Patagonian lambeosaurine.〔 ''Willinakaqe'' was first named by Rubén D. Juárez Valieri, José A. Haro, Lucas E. Fiorelli and Jorge O. Calvo in 2010 and the type species is ''Willinakaqe salitralensis''. The generic name means "Southern duck-mimic", in the Mapuche language (''willi'', "south", ''iná'', "mimic" and ''kaqe'', "duck"). The specific name refers to the Salitral. The largest individuals found were about long. ''Willinakaqe'' had long spines on its pelvis and tail base.〔 == Phylogeny == The describers assigned ''Willinakaqe'' to the Saurolophidae within the Hadrosauroidea.〔 In 2010 cladistic analyses by Prieto-Márquez confirmed that the only two hadrosaurid taxa known from South America, ''Willinakaqe'' and ''Secernosaurus'', form a clade within the Saurolophinae.〔 Prieto-Márquez & Salinas 2010, Prieto-Márquez, 2010 and Juárez Valieri e.a. considered "Kritosaurus" ''australis'' to be identical to ''Secernosaurus''.〔〔 Cladogram after Prieto-Márquez, 2010: |2= }} |2= |2= }} }} }} }} }} }} }} }} 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「Willinakaqe」の詳細全文を読む スポンサード リンク
