Noritoidea

	Noritoidea 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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Noritidae The Noritidae, sometimes spelled Noritidea, is an extinct cephalopod family of belonging to the ammonoid order Ceratitida and superfamily Noritoidea. The Noritidae, which lived during the Early and Middle Triassic, are characterized by smooth, flat, discoidal shells with tabulate venters bordered by pronounced shoulders. Sutures are ceratitic with club-shaped saddles.

	Ophiceratidae The Ophiceratidae is a family in the 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.

	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 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.
