• "Tylonautilus " is a member of the Tainoceratidae which, with other related families, forms the nautiloid superfamily Tainocerataceae.
• The Aipocerataceae are the Solenochilida Flower and are the Solenocheilaceae which Shimansky included in his Rutoceratina minus the Litogyroceratidae which the Treatise includes in the Rutoceratidae ( Tainocerataceae)

• The Tainoceratina differs conceptually from the Tainocerataceae in that the Tetragonoceratidae is the ancestral family, derived from the Rutocerida rather than being an offshoot from the Rutoceratidae and that the various families included within are combined in unique superfamilies.

• The current classification of the Nautilida, in prevalent use, is that of Bernhard Kummel ( Kummel 1964 ) in the Treatise which divides the Nautilida into five superfamilies, the Aipocerataceae, Clydonautilaceae, Tainocerataceae, and Trigonocerataceae, mostly of the Paleozoic, and the later Nautilaceae.
• ""'Cooperoceras " "'is a genus of Tainoceratid nautiloid cephalopod mollusk within the superfamily Tainocerataceae, characterized by and evolute shell with an open, perforate, umbilicus, sinuous ribs at maturity, and recurved hollow spines along the ventro-lateral shoulders.
• ""'Hexagonites " "'is an extinct genus from the nautiloid order, Nautilida which includes the genus " Nautilus " found living in the tropical western Pacific . " Hexagonites " is included in the family Tainoceratidae, part of the superfamily Tainocerataceae ( Kummel, 1964)
