Haloritidae

	Haloritidae The Haloritidae is a family of subglobular, involute, Triassic ammonoids belonging to the ceratitid superfamily Tropitoidea. Their shells may be smooth or may have ribs that cross or are interrupted on the venter, and may have nodes. Keels and ventral furrows are not typical. The last volution is commonly eccentric. The Suture may be ammonitic, ceratitic, or goniatitic. In the present classification of the Haloritidae, the family is divided into two subfamilies, the Haloritinae and the Juvavitinae. In the older classification of the Treatise (1957) the Haloriitidae was divided into three subfamilies, the Haloritinae, with spiral ornamentation weak or absent, the Sagenitinae with prominent spiral ornamentation and a more subdivided suture reassigned to the Pinacocerataceae as the Sagenitidae, and the Episculitinae with a simplified suture and uncoiling of the body chamber The present Haloritinae includes ''Halorites'', the type, ''Amarassites ''Amarassites'' is an extinct ge ...

	Halorites ''Halorites'' is an extinct genus of Triassic ammonoids belonging to the family Haloritidae. Fossil record This genus is known in the fossil record of the Triassic (from about 212 to 205.6 million years ago). Fossils of species within this genus have been found in Indonesia, Canada, India, Oman, Tajikistan and United States. Bibliography * Treatise on Invertebrate Paleontology, Part L, Ammonoidea. R. C.

	Pinacocerataceae Pinacoceratoidea, formerly Pinacocerataceae, are generally smooth, compressed, evolute to involute ammonoids from the Triassic, belonging to the Ceratitida, in which the suture is ammonitic, with adventitious and auxiliary elements. As presently conceived, the Pinacoceratoidea, named by Mojsisovics, 1879, combines six families; the: * Pinacoceratidae * Carnitidae Gymnitidae Isculitidae * Klamathitidae * Sagenitidae In ''Treatise on Invertebrate Paleontology'', Part L, the superfamily included only the Pinacoceratidae and Gymnitidae. Of the families more newly included in the Pinacocerataceae, the Carnitidae was removed from the Ceratitaceae and the Isculitidae from the Ptychitaceae. ''Klamathites'' was removed from the Carnitidae as type for the Klamathitidae. The Sagenitidae is based on the subfamily Sagenitinae of the tropitacean family Haloritidae The Haloritidae is a family of subglobular, involute, Triassic ammonoids belonging to the ceratitid superfamily Tropitoidea.

picture info	Triassic The Triassic ( ) is a geologic period and system which spans 50.6 million years from the end of the Permian Period 251.902 million years ago ( Mya), to the beginning of the Jurassic Period 201.36 Mya. The Triassic is the first and shortest period of the Mesozoic Era. Both the start and end of the period are marked by major extinction events. The Triassic Period is subdivided into three epochs: Early Triassic, Middle Triassic and Late Triassic. The Triassic began in the wake of the Permian–Triassic extinction event, which left the Earth's biosphere impoverished; it was well into the middle of the Triassic before life recovered its former diversity. Three categories of organisms can be distinguished in the Triassic record: survivors from the extinction event, new groups that flourished briefly, and other new groups that went on to dominate the Mesozoic Era. Reptiles, especially archosaurs, were the chief terrestrial vertebrates during this time. A specialized subgroup of archo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]

	Ceratitida Families 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.
