翻訳と辞書　辞書検索 [ 開発暫定版 ] スポンサード リンク Pteranodontoidea ： ウィキペディア英語版 Pteranodontoidea Pteranodontoidea is an extinct clade of ornithocheiroid pterosaurs from the Early Cretaceous to the Late Cretaceous (middle Barremian to middle Campanian stages) of Asia, Europe, North America and South America. It was named by Alexander Wilhelm Armin Kellner in 1996. In 2003, Kellner defined the clade as a node-based taxon consisting of the last common ancestor of ''Anhanguera'', ''Pteranodon'' and all its descendants. Ornithocheiroidea is sometimes considered to be the senior synonym of Pteranodontoidea, however its depends on it definition. Ornithocheiroidea was originally defined as an apomorphy-based taxon by Christopher Bennett in 1994. Later, Kellner (2003) redefined it to represent the node of ''Anhanguera'', ''Pteranodon'', ''Quetzalcoatlus'' and ''Dsungaripterus''.〔Kellner, A. W. A., (2003): Pterosaur phylogeny and comments on the evolutionary history of the group. pp. 105-137. — ''in'' Buffetaut, E. & Mazin, J.-M., (eds.): ''Evolution and Palaeobiology of Pterosaurs''. Geological Society of London, Special Publications 217, London, 1-347〕 Later, David Unwin (2003) suggested a different definition, the node that contains ''Pteranodon longiceps'' and ''Istiodactylus latidens'', thus making ''Pteranodontoidea'' a junior synonym of Ornithocheiroidea.〔Unwin, D. M., (2003): On the phylogeny and evolutionary history of pterosaurs. pp. 139-190. — ''in'' Buffetaut, E. & Mazin, J.-M., (eds.): ''Evolution and Palaeobiology of Pterosaurs''. Geological Society of London, Special Publications 217, London, 1-347〕 Brian Andres (2008, 2010, 2014) in his analyses, converts Ornithocheiroidea using the definition of Kellner (2003) to avoid this synonymy.〔 (A preview that shows the cladogram without clade names )〕 ==Classification== Below is a cladogram showing the results of a phylogenetic analysis presented by Andres & Myers, 2013.
