Noritaceae

	Noritaceae Noritoidea, formerly Noritaceae, is an extinct superfamily of cephalopods belonging to the Ammonite order Ceratitida. Noritoidea, defined by Karpinsky in 1889, combines ceratitids with "typically smooth, more or less discoidal shells with rounded or truncate peripheries and ceratitic sutures,...." Keeled or ribbed offshoots may have simpler or more complex sutures. Taxonomy Noritoidea as revised (Tozer 1981) is composed of the Noritidae, Inyoitidae, Lanceolitidae, Ophiceratidae, Stephanitidae, Ussuriidae Noritidae is the type family of the Noritoidea and may have been derived from the Dieneroceratidae through the Xenoceltitidae. The Inyoitidae is based on the Inyoitinae, which was removed from the Xenoceltitidae and elevated in rank. The Lanceolitidae, containing '' Lanceolites'' as the sole representative, was included in the Hedenstroemiidae as the Lanceolitinae. The Ophiceratidae and the Stephanoceratidae were removed from the Otocerataceae and the Ceratitaceae respe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Ceratitaceae Ceratitoidea, formerly Ceratitaceae, is an ammonite superfamily in order Ceratitida characterized in general by highly ornamented or tuberculate shells with ceratitic sutures that may become goniatitic or ammonitic in some offshoots. (Arkell ''et al.'' 1962) Phylo-taxonomy The Ceratitoidea, according to the ''Treatise on Invertebrate Paleontology'' (fig. 149, L104) can be divided into the Lower Triassic Hellenitidae, Dinaritidae, Tirolitidae, and Stephanitidae; the essentially lower Middle Triassic Acrochordiceratidae, Beyrichitidae, and Proteusitidae; and the lower Middle and post lower Middle Triassic Ceratitidae and its descendant families. Families descendent from the Ceratidae are the Aplococeratidae and possibly or coeval, the Balatonitidae, Danubitidae, and Hungaritidae, and from the Hungaritidae, the Carnitidae. Of these the Balatonitidae and Danubitidae are restricted to the Anisian (lower Middle Triassic); the Ceratitidae and Hungaritidae to the Anisian a ...

	Ceratitida Ceratitida is an order that contains almost all ammonoid cephalopod genera from the Triassic as well as ancestral forms from the Upper Permian The Permian ( ) is a geologic period and stratigraphic system which spans 47 million years from the end of the Carboniferous Period million years ago (Mya), to the beginning of the Triassic Period 251.9 Mya. It is the last period of the Pale ..., the exception being the phylloceratids which gave rise to the great diversity of post Triassic ammonites. Ceratitids overwhelmingly produced planospirally coiled discoidal shells that may be evolute with inner whorls exposed or involute with only the outer whorl showing. In a few later forms the shell became subglobular, in others, trochoidal or uncoiled. Sutures are typically ceratitic, with smooth saddles and serrate or digitized lobes. In a few the sutures are goniatitic while in others they are ammonitic. Taxonomy * Ceratitida Ceratitoidea Choristoceratoidea Clydonitoide ...

	Ophiceratidae The Ophiceratidae is a family in the ammonoidea, ammonoid order Ceratitida from the Lower Triassic, previously included in the Otocerataceae but now placed in the Noritiaceae as revised. The Ophiceratidae produced sepenticones with compressed elliptical whorl sections in which the venter is generally rounded and ornamentation is usually weak. The suture is simple, ceratitic. Named genera include ''Ophiceras'', the type, ''Discophiceras'', ''Nordophiceras'', ''Sakhaites'', ''Vishnuites'', and ''Wordieoceras''. The phonetically similar Ophioceratidae of Strand 1934 is synonymous with Ophidioceratidae Hyatt, 1894 a family in the nautiloid cephalopod order, Tarphycerida.

	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 periwinkle). Furthermore, every so often, previously published volumes of the ''Treatise'' are revised. Evolution of the project Raymond C. Moor ...
