Anthracosauria
Node. Seymouriamorpha (maybe)
Reptiliomorpha. Reptiliomorpha is a clade containing the amniotes and those tetrapods that share a more recent common ancestor with amniotes than with living amphibians (lissamphibians).
It was defined by Michel Laurin (2001) and Vallin and Laurin (2004) as the largest clade that includes Homo sapiens but not Ascaphus truei.[1][2] The informal variant of the name, "reptiliomorphs", is also occasionally used to refer to stem-amniotes, i.e. a grade of reptile-like labyrinthodont tetrapods that are more closely related to amniotes than they are to lissamphibians, but are not amniotes themselves; the name is used in this meaning e.g. by Ruta, Coates and Quicke (2003).[3] An alternative name, "Anthracosauria" is also commonly used for the group but is confusingly also used for the more primitive grade of reptiliomorphs by Benton.[4]
