Therapsida? are direct mammal's ancestors, but some scientists consider them to be mammals. In this case, Pelycosauria? are direct mammal's ancestor.

Names Prototheria, Metatheria and Eutheria expressed theory that Placentalia? were descendants of Marsupialia?, which were in turn descendants of Monotlremata?. Because this theory has been refuted, these names are rarely used nowadays.
