Nothosauridae are an extinct family of carnivorous aquatic sauropterygian reptiles from the Triassic time period of China, France, Germany, Israel, Italy, Netherlands, Russia, Switzerland, and northern Africa.〔(The Paleobiology Database: Nothosauridae )〕〔(Nothosauridae )〕 ==Phylogeny== The cladogram shown below follows Rieppel (1998)'s phylogenetic analysis of nothosaurids (bold terminal taxa contain living species). Most of these relations are still considered correct today, but despite Rieppel (1998)'s referral of ''Ceresiosaurus'' and ''Silvestrosaurus'' to ''Lariosaurus'', some authors still consider them separate and many additional species have been named since this analysis. |2= |label2= Nothosauroidea |2= }} }} }} }} }} }} }} }} }} }} }} A species level phylogenetic analysis of Nothosauridae was performed by Liu ''et al.'' (2014), and included all known valid species of the family apart from ''Lariosaurus stensioi'' (type of ''Micronothosaurus''), ''Nothosaurus cymatosauroides'', and ''Ceresiosaurus lanzi''. The resultant topology is similar to the one obtained in Rieppel (1998) if the new additions are ignored, however this analysis found both ''Lariosaurus'' and ''Nothosaurus'' to be polyphyletic in regard to each-other and all other genera of the family, making a systematic revision of these two genera necessary. Below, their results are shown with type species of named nothosaurid genera noted. |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「Nothosauridae」の詳細全文を読む スポンサード リンク
