Paraloxoceras is a genus of straight shelled, orthoconic nautiloid cephalopods, now extinct, that lived during the Early Carboniferous. Fossils have been found in Europe and central Asia; the type, P. konincki, named by Flower, came from Belgium.
Jangziceras is a genus of fossil nautiloid cephalopods from the Middle Silurian of southern China belonging to the Orthocerida incertae sedis, its familial association undetermined. The type is Jangziceras sichuanense Lai Chai-Geen. Its description falls within the characters of the Orthocerida.
Tienocerasis an orthoceratoid genus from the Permian of China (Hunan). Orthoceratoids are slender conical or near cylindrical, orthoconic, nautiloid cephalopods from the Paleozoic. Nautiloids, which include a number of different extinct orders, were far more diverse and numerous in the past, but are represented today by only two closely related genera.
Kionoceras is an extinct nautiloid cephalopod genus included in the orthocerid family Kionoceratidae with scattered worldwide distribution from the Middle Ordovician to the Lower Permian. Kionoceratids are orthocerids with prominent longitudinal ornamentation on their shells, sometimes augmented by secondary transverse ornamentation. Orthocerids are, of course, prehistoric nautiloides with generally straight and elongate shells, mostly with central or subcentral siphuncles.
Sinoceras is an extinct genus of nautiloids from China included in the family Orthoceratidae that lived from the middle Ordovician until the Devonian. The type species, S. chinense, was originally described as "Orthoceras chinense," but then was promoted by Shimizu and Obata to its own genus, Sinoceras, in 1935.
