Hyperodapedontinae is a subfamily of rhynchosaurs within the family Hyperodapedontidae. Fossils have been found from Argentina, Brasil, Canada, India, Madagascar, Scotland, Tanzania, USA and Zimbabwe. ==Phylogeny== Hyperodapedontinae was erected by Sankar Chatterjee in 1969 as a coordinate name of the family Hyperodapedontidae Lydekker, 1985. Chatterjee (1969) originally named Hyperodapedontinae to include all Late Triassic rhynchosaurs known at that time, ''H. gordoni'', ''H. huxleyi'' and ''"Scaphonyx" fischeri'', and proposed a morphological diagnosis for the clade.〔 ''Scaphonyx'' includes two additional species, ''S. africanus'' and ''S. australis'', all of which are currently believed to be dubious. As noted by Langer ''et al.'' (2000), using Chatterjee' morphological definition would exclude ''Teyumbaita'' and ''H. huenei'' from the clade, and thus it would be nested within ''Hyperodapedon''. To preserve the name, with its original stratigraphical meaning, Langer ''et al.'' (2000) redefined Hyperodapedontinae as a stem-based taxon that includes "all rhynchosaurs closer to ''Hyperodapedon'' than to ''"Rhynchosaurus" spenceri'' (now ''Fodonyx'')". The cladogram below follows Langer ''et al.'' (2000) and Langer ''et al.'' (2010): }} }} }} }} Valid species that were first assigned to ''Scaphonyx''. The cladogram below is based on Hone and Benton (2008). Hone & Benton (2008) applied all clade names within the Rhynchosauria to nodes in their topology incorrectly with respect to the definitions proposed by Langer ''et al.'' (2000) and Langer ''et al.'' (2010). As Hone & Benton (2008) didn't propose alternative definitions, the cladogram below follows Langer ''et al.'' (2000) definitions.〔 }} }} }} }} }} }} 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「Hyperodapedontinae」の詳細全文を読む スポンサード リンク
