Thoracopteridae is an extinct family of prehistoric bony fish; classified with the order Peltopleuriformes. This lineage of Triassic flying fish-like Perleidiformes, converted their pectoral and pelvic fins into broad wings very similar to those of their modern counterparts.
Peltopleuriformes were an extinct order of prehistoric bony fish.
Gigantopterus is an extinct genus of prehistoric bony fish that lived during the Carnian stage of the Late Triassic epoch.
Potanichthys is a fossil genus of flying or gliding fish found in deposits in China dating to the Ladinian age of the Middle Triassic epoch. However, the fossil is not related to modern flying fish, which evolved independently about 66 million years ago. It is classified under the extinct family Thoracopteridae of the order Perleidiformes. It contains only one species, Potanichthys xingyiensis.
Thoracopterus is an extinct genus of over water gliding bony fish. It was common to the late Triassic period.
The Percopsiformes are a small order of ray-finned fishes, comprising the trout-perch and its allies. It contains just ten extant species, grouped into seven genera and three families. Five of these genera are monotypic
Anseriformes is an order of birds that comprise about 180 living species in three families: Anhimidae, Anseranatidae, and Anatidae, the largest family, which includes over 170 species of waterfowl, among them the ducks, geese, and swans. Most modern species in the order are highly adapted for an aquatic existence at the water surface. With the exception of screamers, all have phalli, a trait that has been lost in the Neoaves. Due to their aquatic nature, most species are web-footed.
Acipenseriformes is an order of basal ray-finned fishes that includes the sturgeons and paddlefishes, as well as some extinct families.
The Amiiformes order of fish has only one extant species, the bowfin.
Semionotiformes is an order of primitive, ray-finned, primarily freshwater fish from the Triassic to the Cretaceous. The best-known genus is Semionotus of Europe and North America.
The chachalacas, guans and curassows are birds in the family Cracidae. These are species of tropical and subtropical Central and South America. The range of one species, the plain chachalaca, just reaches southernmost parts of Texas in the United States. Two species, the Trinidad piping guan and the rufous-vented chachalaca occur on the islands of Trinidad and Tobago respectively.
The Elopiformes are the order of ray-finned fish including the tarpons, tenpounders, and ladyfish, as well as a number of extinct types. They have a long fossil record, easily distinguished from other fishes by the presence of an additional set of bones in the throat.
The beardfishes consist of a single extant genus, Polymixia, of deep-sea marine ray-finned fish named for their pair of long hyoid barbels. At present they are classified in their own order Polymixiiformes, but as Nelson says, "few groups have been shifted back and forth as frequently as this one". For instance, they have previously been classified as belonging to the Beryciformes. They are of little economic importance.
Triakis is a genus of houndsharks in the family Triakidae. The name comes from the Greek word τρι, tri meaning "three", and the Latin word acis meaning "sharp" or "pointed", in reference to the three-pointed teeth of these sharks.
The Palaeonisciformes are an extinct order of early ray-finned fishes (Actinopterygii) which began in the Late Silurian and ended in the Late Cretaceous. The name of the order is derived from the Greek words paleo (ancient) and ὀνίσκος, probably pertaining to the organization of the fishes' scales, similar to the exoskeletal plating of woodlice.
Aspidorhynchiformes is an extinct order of prehistoric ray-finned fish that was described by Bleeker in 1859.
Pycnodontiformes is an extinct order of bony fish. The group evolved during the Late Triassic and disappeared during the Eocene. The group has been found in rock formations in Africa, Asia, Europe, North and South America.
Saurichthyiformes is a group of ray-finned fish which existed in China, Europe and North America, during the late Permian to early Jurassic periods.
Perleidiformes are an extinct order of prehistoric ray-finned fish
Pholidopleuriformes is an extinct order of prehistoric ray-finned fish.
Crossognathiformes were an extinct order of prehistoric ray-finned fish.
Peltopleuridae were an extinct family of prehistoric bony fish. It is classified with the order Peltopleuriformes.
The Otocephala is a clade of bony fishes within the Teleostei that evolved some 230 million years ago. It is named for the presence of a hearing (otophysic) link from the swimbladder to the inner ear. Other names proposed for the group include Ostarioclupeomorpha and Otomorpha. The clade contains the Clupeiformes (herrings) and the Ostariophysi, a group of other orders including the Cypriniformes, Gymnotiformes (knifefish), and Siluriformes (catfish). The Otocephala may also contain the Alepocephaliformes (slickheads), but as yet (2016) without morphological evidence. The clade is sister to the Euteleostei which contains the majority of bony fish alive today. In 2015, Benton and colleagues set a "plausible minimum" date for the origin of the crown Otocephala as about 228.4 million years ago. They argued that since the oldest locality for any diversity of stem teleosts is the Carnian of Polberg bei Lunz, Austria, whose base is 235 million years old, a rough estimate for the Otocephala can be made.
