The Wynyardiidae family, which includes the primitive genera of Vombatimorphia, may not be a monophyletic family. It is regarded as the primitive sister group of all other families of the Vombatimorphia. The Wynyardiidae family includes three genera, each with one species. These are Muramura williamsi PLEDGE, 1987c from the late Oligocene , Namilamadeta snideri RICH, ARCHER, 1979 from the late Oligocene and Wynyardia bassiana SPENCER, 1901 from the early Miocene .
