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.

Raymondiceratinae
Raymondiceratinae is a subfamily of Upper Devonian cheiloceratid goniatites in which the sutures have 4 distinct lobes and the growth lines are convex. The subfamily includes three genera. *''Raymondiceras''. named by Schindewolf, 1934 which has a subglubular shell with small closed umbilici and sutures with an incipient lobe in the first lateral saddle. Type genus. *''Melonites'' named by Bogoslovskii 1971, which was moved from Cheiloceratidae to Raymondiceratineae by Korn & Klug, 2002. *''Roinghites ''Roinghites'' is genus of ammonoid cephalopod belonging to the Cheiloceratidae family.

Tornoceratidae
Tornoceratidae is a family of goniatitid ammonoids from the middle and upper Devonian. The family is included in the suborder Tornoceratina and the superfamily Tornoceratoidea. Tornoceratids are subdiscoidal goniatitids with biconvex growth lines and sutures that form 6 to 10 lobes, the ventral one undivided, the lateral ones originating as subdivisions of external and internal lateral saddle. They are derived from the Anarcestida. Taxonomy Tornoceratidae as now understood is essentially the Tornoceratidae of Arthaber (1911) described in the American Treatise on Invertebrate Paleontology, Part L, revised to include three subfamilies, the Tornoceratinae, Aulatornoceratinae, and Falcitornoceratinae. Miller ''et al''. (1957) included the Tornoceratidae without subfamilies in the Cheilocerataceae, a superfaminily in the Goniatitida which also includes the Cheiloceratidae. Tornoceratinae is based on the genus ''Tornoceras'' described by Alpheus Hyatt in 1884. Aulatornocera ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Gattendorfiidae is one of seven families of the superfamily Prionoceratoidea, a member of the Goniatitida order. They are an extinct group of ammonoid, which are shelled cephalopods related to squids, belemnites, octopuses, and cuttlefish, and m ..., Prionoceratidae, Pseudarietitidae, and Voehringeritidae.

Goniatitida Families
Goniatids, informally goniatites, are ammonoid cephalopods that form the order Goniatitida, derived from the more primitive Agoniatitida during the Middle Devonian some 390 million years ago (around Eifelian stage). Goniatites (goniatitids) survived the Late Devonian extinction to flourish during the Carboniferous and Permian only to become extinct at the end of the Permian some 139 million years later. Morphology All goniatites possessed an external shell, which is divided internally into chambers filled with gas giving it buoyancy during the life of the animal. An open chamber at the front of the shell provided living space for the goniatitid animal, with access to open water through a ventral siphuncle. The general morphology and habit of goniatites was probably similar to that of their later relatives the ammonites, being free swimming and possessing a head with two well developed eyes and arms (or tentacles). Goniatite shells are small to medium in size, almost always l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Devonian
The Devonian ( ) is a geologic period and system of the Paleozoic era, spanning 60.3 million years from the end of the Silurian, million years ago (Mya), to the beginning of the Carboniferous, Mya. It is named after Devon, England, where rocks from this period were first studied. The first significant adaptive radiation of life on dry land occurred during the Devonian. Free-sporing vascular plants began to spread across dry land, forming extensive forests which covered the continents. By the middle of the Devonian, several groups of plants had evolved leaves and true roots, and by the end of the period the first seed-bearing plants appeared. The arthropod groups of myriapods, arachnids and hexapods also became well-established early in this period, after starting their expansion to land at least from the Ordovician period. Fish reached substantial diversity during this time, leading the Devonian to often be dubbed the Age of Fishes. The placoderms began dominating ...
