“ANAMNIOTES”

.

*”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”)

(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))

(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’)

.

(as the exact ‘phylogenetic’ position of ‘lissamphibia’ within ‘Tetrapoda’ remains uncertain, it also remains controversial which fossil ‘tetrapods’ are more closely related to ‘amniotes’ than to ‘lissamphibians’, and thus, which ones of them were ‘reptiliomorphs’ in any meaning of the word)
