Saurichthyiformes
Saurichthyiformes is an extinct order of ray-finned fish which existed in Asia, Africa, Australia, Europe and North America, during the late Permian to early Middle Jurassic. Saurichthyiiformes comprise two families, Saurichthyidae and Yelangichthyidae. Whereas Yelangichthyidae is monotypic, Saurichthyidae includes at least two genera, ''Saurorhynchus'' and the very speciose ''Saurichthys''. Additionally, the subgenera '' Costasaurichthys'', '' Eosaurichthys'', '' Lepidosaurichthys'', and ''Sinosaurichthys'' are frequently used to group species. Saurichthyiforms were highly successful predators, and with ''Yelangichthys'' possibly even included durophagous forms. Species are known from both marine end freshwater deposits. They had their highest diversity during the Early and Middle Triassic.

Saurorhynchus
''Saurorhynchus'' (= ''Acidorhynchus'') is an extinct genus of carnivorous bony fish. It is the youngest representative of the family Saurichthyidae and the order Saurichthyiformes. This family is known for its large, elongate jaws, similar to modern Belonidae. Saurichthyidae also includes the Permian genus '' Eosaurichthys'' and the Triassic genus ''Saurichthys''. Fossils of ''Saurorhynchus'' have been found in Europe (France France (), officially the French Republic ( ), is a country primarily located in Western Europe.

Sinosaurichthys
''Sinosaurichthys'' is an extinct genus of saurichthyid ray-finned fish, which existed in southwestern China during the Middle Triassic (Anisian age). Fossils have been found in the Upper Member of the Guanling Formation of two localities: Yangjuan of Panxian County, Guizhou Province, and Dawazi of Luoping, Yunnan Province, China. It was first named by Wu Feixiang, Sun Yuanlin, Xu Guanghui, Hao Weicheng, Jiang Dayong and Sun Zuoyu in 2010. The type species is ''Sinosaurichthys longipectoralis''. There are two additional species, ''S. longimedialis'' and ''S. minuta''. The species ''Saurichthys spinosa'' from the Middle Triassic of China may be closely related with ''Sinosaurichthys''.

Eosaurichthys
''Eosaurichthys'' is an extinct saurichthyid ray-finned fish that lived during the late Permian epoch (Changhsingian age) in what is now China. It closely resembles its daughter genus, ''Saurichthys'', in both form and morphology. ''Eosaurichthys'' is often treated as a subgenus of ''Saurichthys'' rather than a genus, with its type species referred to as ''Saurichthys'' (''Eosaurichthys'') ''chaoi''. The Early Triassic species ''Saurichthys madagascariensis'' has been referred to this subgenus as ''Saurichthys'' (''Eoaurichthys'') ''madagascariensis''.

Actinopterygii
Actinopterygii (; ), members of which are known as ray-finned fishes, is a class of bony fish. They comprise over 50% of living vertebrate species. The ray-finned fishes are so called because their fins are webs of skin supported by bony or horny spines (rays), as opposed to the fleshy, lobed fins that characterize the class Sarcopterygii (lobe-finned fish). These actinopterygian fin rays attach directly to the proximal or basal skeletal elements, the radials, which represent the link or connection between these fins and the internal skeleton (e.g., pelvic and pectoral girdles). By species count, actinopterygians dominate the vertebrates, and they constitute nearly 99% of the over 30,000 species of fish. They are ubiquitous throughout freshwater and marine environments from the deep sea to the highest mountain streams. Extant species can range in size from ''Paedocypris'', at , to the massive ocean sunfish, at , and the long-bodied oarfish, at . The vast majority of Actinopt ...

Subgenus
In biology, a subgenus (plural: subgenera) is a taxonomic rank directly below genus. In the International Code of Zoological Nomenclature, a subgeneric name can be used independently or included in a species name, in parentheses, placed between the generic name and the specific epithet: e.g. the tiger cowry of the Indo-Pacific, ''Cypraea'' (''Cypraea'') ''tigris'' Linnaeus, which belongs to the subgenus ''Cypraea'' of the genus ''Cypraea''. However, it is not mandatory, or even customary, when giving the name of a species, to include the subgeneric name. In the International Code of Nomenclature for algae, fungi, and plants (ICNafp), the subgenus is one of the possible subdivisions of a genus. There is no limit to the number of divisions that are permitted within a genus by adding the prefix "sub-" or in other ways as long as no confusion can result. Article 4 The secondary ranks of section and series are subordinate to subgenus. An example is ''Banksia'' subg. ''Isostylis'', ...

Changhsingian
In the geologic time scale, the Changhsingian or Changxingian is the latest age or uppermost stage of the Permian. It is also the upper or latest of two subdivisions of the Lopingian Epoch or Series. The Changhsingian lasted from to 251.902 million years ago (Ma). It was preceded by the Wuchiapingian and followed by the Induan. The greatest mass extinction in the Phanerozoic eon, the Permian–Triassic extinction event, occurred during this age. The extinction rate peaked about a million years before the end of this stage. Stratigraphic definitions The Changhsingian is named after Changxing () in northern Zhejiang, China. The stage was named for the Changhsing Limestone. The name was first used for a stage in 1970; 1973: ''Permian stages names'', in: : ''The Permian and Triassic systems and their mutual boundary'', Canadian Society of Petroleum Geologists Memoir 2, pp 522–548. and was anchored in the international timescale in 1981.; 2006: ''The Global Boundary Stratotype Sect ...
