However, it is regarded here as an aberrant Onchopristis numidus , the typical form from North Africa. An aberrant morph of O. numidus is considered pathological. The taxonomic utility of barb number in pristid rostral ‘teeth’ is discussed. The genus and species Australopristis wiffeni gen. et sp. nov is erected to accommodate some multi-cusped rostral teeth from the Late Cretaceous of New Zealand.
