Ausktribosphenidae is a group name that has been given to some rather puzzling fossils—Ausktribosphenos nyktos and Bishops whitmorei—which
Ausktribosphenidae and monotremes have been assigned to the larger group Australosphenida. But Australosphenida is a group which has been defined only in order to include the Ausktribosphenidae and monotremes - in other words, it may be just a fiction, unless someone finds a fossil which can sensibly be described as a "basal australosphenid" (member of the Australosphenida which belongs to neither Ausktribosphenidae nor monotremes).
