"Mesosuchia" is an obsolete name for a group of terrestrial, semi-aquatic, or fully aquatic crocodylomorph reptiles. The marine crocodile ''Metriorhynchus'' had paddle-like forelimbs, ''Dakosaurus andiniensis'' had a skull that was adapted to eat large sea reptiles, and ''Shamosuchus'' was adapted for eating molluscs and gastropods. ''Shamosuchus'' also looked like modern crocodiles and was very closely related to their direct ancestor. The "Mesosuchia" were formerly placed at Suborder rank as within Crocodylia. The "first" crocodiles were placed within their own suborder, Protosuchia; whilst extant species where placed within Suborder Eusuchia (meaning 'true crocodiles'). Mesosuchia were the crocodylians "in between". As it is a paraphyletic group however, it is not considered valid anymore. It is replaced by its phylogenetic equivalent Mesoeucrocodylia, which contains the taxa herein, the Crocodylia, and some allied forms more recently discovered. The "Mesosuchia" was composed as: * Family Hsisosuchidae * Family Gobiosuchidae * * Infraorder Notosuchia * * * Family Notosuchidae * * * Family Sebecidae * * * Family Baurusuchidae * * Infraorder Neosuchia * * * Family Trematochampsidae * * * Family Peirosauridae * * * * Genus ''Lomasuchus'' * * * * Genus ''Montealtosuchus'' * * *Family Elosuchidae * * * Family Atoposauridae * * * Family Dyrosauridae * * * Family Pholidosauridae * * * * Genus ''Sarcosuchus'' * * * Infraorder Thalattosuchia - Sea "Crocodiles" * * * * Family Teleosauridae * * * * Family Metriorhynchidae * * * * *Genus ''Dakosaurus'' * * * Family Goniopholididae * * * Family Paralligatoridae * * * * Genus ''Shamosuchus'' ==External links== *(Unterordnung Mesosuchia ) *(A teleosaurid (Crocodylia, Mesosuchia) from the Toarcian of Madagascar and its palaeobiogeographical significance ) *(Blue Nile Gorge ) *(In German ) *(Shantungosuchus ) *(Crocodyliformes ) *(Crocodile Evolution ) 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「Mesosuchia」の詳細全文を読む スポンサード リンク
