Chamaeleontiformes is a hypothesized clade (evolutionary grouping) of iguanian lizards defined as all taxa sharing a more recent common ancestor with ''Chamaeleo chamaeleon'' (the common chamaeleon) than with ''Hoplocercus spinosus'' (the Brazilian spiny-tailed lizard), ''Polychrus marmoratus'' (bush lizard), or ''Iguana iguana'' (green iguana). It was named by paleontologist Jack Conrad in 2008 to describe a clade recovered in his phylogenetic analysis that included the extinct genus ''Isodontosaurus'', the extinct family Priscagamidae, and the living clade Acrodonta, which includes agamids and chameleons. It is a stem-based taxon and one of two major clades within Iguania, the other being Pleurodonta. Below is a cladogram from Daza ''et al.'' (2012) showing this phylogeny: |label2=Iguania |2= |2=Iguanoidea (=Pleurodonta) }} }} }} }} Other analyses place Priscagamidae outside Iguania altogether, resulting in a Chamaeleontiformes that only includes ''Isodontosaurus'' and Acrodonta. Below is a cladogram from Conrad (2015) with this phylogeny: |2=Pleurodonta }} }} }} }} == References == 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「Chamaeleontiformes」の詳細全文を読む スポンサード リンク
