Agathiceratidae
Agathiceratidae, as revised, makes up the goniatitid superfamily Agathiceratoidea. Agathiceratidae, which lived from the Upper Carboniferous (Pennsylvanian) to the Middle Permian, combine related genera with subdiscoidal to globular shells that have a small umbilicus and goniatitic sutures and are prominently longitudinally lirate. (Miller ''et al.'' 1960) The explanation for the Agathiceratidae is that for the Agathiceratoidea. Agathiceratidae may have its origin in ''Dombarites'' (Saunders ''et al.'' 1999) which has been removed to the Delepinoceratidae (Furnish ''et al.'' 2009). Delepinoceratidae is now one of two families that make up the Goniatitoidea. In current taxonomy (Furnish ''et al.'' 2009), Agathiceratidae contains '' Agathiceras'', '' Gaetanoceras'', '' Paragathiceras'', and '' Pericleites'' as compared to ''Dombarites'', '' Paracravenoceras'', ''Periclietes'', '' Proshumardites'', and ''Agathiceras'' in Saunders ''et al.'' (1999). ''Paracravenoceras'' is now ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dombarites
''Dombarites'' is a genus belonging to the goniatitid family Agathiceratidae; extinct ammonoids which are shelled cephalopods more closely related to squid, octopus and other coleoids than to the superficially similar ''Nautilus'' According to Saunders, et al., 1999, Dombarites from the middle and upper Lower Carboniferous (Mississippian) is the earliest of the Agathiceratidae; gave rise to '' Perclietes'' and '' Proshumardites'' in the late Early Carboniferous and indirectly to '' Agathiceras'' which first appeared in the middle Upper Carboniferous (Pennsylvanian). Dombarites is derived from '' Goniatites'', a genus in the Goniatitidae Goniatitidae is one of three families included in the ammonoid cephalopod superfamily Goniatitoidea, known from the Lower Mississippian to the Upper Permian The Permian ( ) is a geologic period and System (stratigraphy), stratigraphic syste ..., in the middle Early Carboniferous.

Agathiceras
''Agathiceras'' is a subglobose goniatitid from the family Agathiceratidae, widespread and locally abundant in Lower Pennsylvanian to Middle Permian sediments, e.g. the Urals, Sicily, and Texas. ''Agathiceras'', named by Gemmellaro in 1887 from the Middle Permian Sicilian species, '' A. suessi'', has a broadly rounded outer edge, known as the venter, being at the lower side of the animal during life, and a deeply impressed innerside, the dorsum which corresponds with the back or dorsal side of the animal. The sutures are goniatitic with three lateral and one dorsolateral lobes on either side. Those that are external are spatulate, those hidden are V-shaped. The siphuncle is primitive with the septal necks pointing to the rear, a condition known as retrosiphonate. ''Agathiceras'' is thought to be derived from ''Proshumardites'' according to Saunders ''et al''. (1999), which is thought to be derived from ''Dombarites''; all of which are included in the Agathiceratidae. ''Dombar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Goniatitoidea
Goniatitoidea, formerly Goniatitaceae in older publications, is a superfamily of late Paleozoic ammonoid cephalopods included in the Goniatitida Goniatids, informally goniatites, are Ammonoidea, 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 (goniat .... They are characterized by thinly discoidal to globular shells with variable umbilici and sculpture. The ventral lobe, located along the outer margin, is prominently bifurcated (two pronged); the lateral lobe undivided. References * Miller, Furnish, and Schindewolf 1957.

Goniatitina
Goniatitina is one of two suborders included in the order Goniatitida; extinct Paleozoic Ammonoidea, ammonoid cephalopods only distantly related to the Nautiloidea.

Treatise On Invertebrate Paleontology
The ''Treatise on Invertebrate Paleontology'' (or ''TIP'') published by the Geological Society of America and the University of Kansas Press, is a definitive multi-authored work of some 50 volumes, written by more than 300 paleontologists, and covering every phylum, class, order, family, and genus of fossil and extant (still living) invertebrate animals. The prehistoric invertebrates are described as to their taxonomy, morphology, paleoecology, stratigraphic and paleogeographic range. However, taxa with no fossil record whatsoever have just a very brief listing. Publication of the decades-long ''Treatise on Invertebrate Paleontology'' is a work-in-progress; and therefore it is not yet complete: For example, there is no volume yet published regarding the post-Paleozoic era caenogastropods (a molluscan group including the whelk and Common periwinkle, periwinkle). Furthermore, every so often, previously published volumes of the ''Treatise'' are revised. Evolution of the proje ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
List Of Nautiloids
This list of nautiloids is a comprehensive listing of all genera that have ever been included in the subclass Nautiloidea, excluding purely vernacular terms. The list includes all commonly accepted genera, but also genera that are now considered invalid, doubtful (''nomina dubia''), or were not formally published (''nomina nuda''), as well as junior synonyms of more established names, and genera that are no longer considered nautiloids. Most of the listed genera are found in Part K of the ''Treatise on Invertebrate Paleontology''. Some, added since the year of publication (1964) are found simply in various scientific journals and special publications. The named genera are based on type specimens which are housed in various museums and other academic institutions worldwide, available to interested researchers. Note that ''Allonautilus'' and ''Nautilus'' are the only extant genera. A *†'' Acanthonautilus'' *†'' Acaroceras'' *†'' Acleistoceras'' *†'' Acrosphaerorthoceras' ...
