Ankylopoda is a clade that contains turtles and lepidosaurs (Tuatara, lizards and snakes) and their fossil relatives. This clade is supported based on microRNAs〔Lyson, T.R., Sperling, E.A., Heimberg, A.M., Gauthier, J.A., King, B.L., Peterson, K.J., 2012. MicroRNAs support a turtle + lizard clade. Biol. Lett. 8, 104–107.〕 as well as the fossil record.〔Schoch, R. R. & Sues, H.-D. A Middle Triassic stem-turtle and the evolution of the turtle body plan. Nature advance online publication, (2015).〕 Stem-turtles and lepidosaurs have unique skull elements and features not seen in archosaurs (represented by extant crocodilians and birds). ==Classification== The cladogram below follows the most likely result found by another analysis of turtle relationships, this one using only fossil evidence, published by Rainer Schoch and Hans-Dieter Sues in 2015. This study found ''Eunotosaurus'' to be an actual early stem-turtle, though other versions of the analysis found weak support for it as a parareptile. |label2= Pantestudines |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「Ankylopoda」の詳細全文を読む スポンサード リンク
