Sauropsida — Mammalia

  • Peter Ax


The monophyly of an entity Sauropsida (= Reptilia) with the adelphotaxa Chelonia and Diapsida still appears to be a subject of controversy. In any case, a monophylum with this name is not so convincing and universally justifiable as is the case for the Tetrapoda in their entirety, for the Ayes as a subtaxon of the Sauropsida or for the sister group Mammalia.
