Centroceratidae
The Centroceratidae is the ancestral family of the Trigonoceratoidea and of the equivalent Centroceratina; extinct shelled cephalopods belonging to the order Nautilida Diagnosis The Centroceratidae, which range from the Middle Devonian to the Lower Permian, are characterized by gyroconic, evolute tarphyceraconic, and involute nautiliconic shells with compressed whorls, typically with a quadrangular whorl section in which the flanks converge on venter that is much narrower than the dorsum and ventral and umbilical shoulders are sharply angular, or rarely rounded. In some, e.g. ''Centroceras'', the flanks are divided by a ridge that runs along the middle. Sutures have ventral and lateral lobes but are transverse dorsally. The siphuncle is tubular and close to but not on in contact with the venter (Kummel 1964). Phylogeny and genera Evolutionary sequence The Centroceratidae are thought probably to be derived from the rutoceratid stock (Flower 1950, 1988, Kummel 1964) Earliest are ...

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 external lateral saddles. Taxonomy The taxonomy of the Cheiloceratidae varies according to the perception of different researchers over time and can be considered a work in progress. That presented in the taxobox is simply one of the more recent. Cheiloceratidae is the larger of two families included in the Cheilocerataceae in the 1957 Treatise Part L, the other being the Tornoceratidae.A.K Miller, W.M Furnish, and O.H. Schindewolf, 1957. Paleozoic Ammonoidea. Treatise on Invertebrate Paleontology, Part L, Mollusca 4. Geological Soc. of America and Univ. Kansas Press. The Cheiloceratidae (M,F,&S) range from the Upper Devonian to the Middle Permian and includes 4 subfamilies. Cheiloceratinae is essentially the Cheiloceratidae of Saunders et ...
