The inclusive taxonomy of the Prionoceratoidea varies according to classification. In some, valid families are the Gattendorfiidae, Prionoceratidae, Pseudarietitidae, and Voehringeritidae. Others may add the Acrocanitidae, Cheiloceratidae, Praeglyphioceratidae, and Sporadoceratidae to the list although it is not at all clear that these belong.
