Prionocerataceae
Prionoceratoidea is a superfamily in the goniatitid suborder, Tornoceratatina that was extant during the latter Paleozoic. 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 Cheiloceratidae is a family of ammonoid cephalopods included in the goniatitid suborder Tornoceratina in which the suture has 4 to 12 lobes, the ventral one undivided and those in the lateral areas originating as subdivisions of internal and ex ..., Praeglyphioceratidae, and Sporadoceratidae to the list although it is not at all clear that these belong.
