The Gonorynchiformes are an order of ray-finned fish that includes the important food source, the milkfish, and a number of lesser-known types, both marine and freshwater.
The milkfish is a widespread species of ray-finned fish found throughout the Indo-Pacific. It is the sole living species in the family Chanidae, and the only living member of the genus Chanos.. The repeating scientific name (tautonym) is from Greek khanos.
Gonorynchus is a genus of long thin gonorynchiform ray-finned fish, commonly called beaked salmon or beaked sandfish. They live on sandy bottoms near shorelines of the temperate & subtropical Southern Hemisphere and East Asia. There are five known extant species which are placed in this genus. All have a distinctive angular snout that the fish use to dig themselves into the sand. A swim bladder is absent.
Gonorynchidae is a family of ray-finned fish in the order Gonorynchiformes, which has a number of fossil taxa and one extant genus, Gonorynchus, the beaked salmons. They are an ancient group, with fossils known from as far back as the Albian stage of the Early Cretaceous.
Belonostomus is a genus of prehistoric ray-finned fish that was described by Louis Agassiz in 1844. It is a member of the order Aspidorhynchiformes, a group of fish known for their distinctive elongated rostrums.
Cheirothrix is an extinct genus of marine ray-finned fish from the Late Cretaceous. It is named for its enlarged pectoral fins, which show close convergence with modern flying fish.
Prionolepis is a genus of prehistoric ray-finned fish belonging to the order Alepisauriformes.
Saurodon is an extinct genus of ichthyodectiform fish from the Cretaceous.
Pycnodontiformes is an extinct order of primarily marine bony fish. The group first appeared 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. They were small to middle-sized fish, generally with laterally-compressed deep bodies, some with almost circular outlines, adapted for manuverability in reef-like environments, though the group was morphologically diverse. Most, but not all members of the groups had jaws with round and flattened teeth, well adapted to crush food items (durophagy), such as echinoderms, crustaceans and molluscs. Some pyncodontiformes developed piranha like teeth used for eating flesh. Most species inhabited shallow marine reef environments, while a handful of species lived in freshwater or brackish conditions. While rare during the Triassic and Early-Middle Jurassic, Pycnodontiformes became abundant and diverse during the Late Jurassic, exhibiting a high but relatively static diversity during the Early Cretaceous. At the beginning of the Late Cretaceous they reached their apex of morphological and species diversity, after which they began to gradually decline, with a more sudden decline at the end of the Cretaceous due to the collapse of reef ecosystems, finally becoming extinct during the Eocene. They are considered to belong to the Neopterygii, but their relationship to other members of that group is uncertain.
Chirocentrites is an extinct genus of marine ray-finned fish in the order Ichthyodectiformes. It contains a single species, C. coroninii, from the Late Cretaceous (Cenomanian) of Slovenia. A potential specimen is also known from the Albian-aged Pietraroja Plattenkalk of southern Italy, but it has been suggested that this specimen actually represents Cladocyclus.
Aipichthys is an extinct genus of bony fish that is possibly polyphyletic. Formerly classified in the Polymixiiformes, it is now thought to be a distant relative of oarfish and opahs.
Coccodus is an extinct genus of extinct pycnodontid fish that lived during the lower Cenomanian. The various species had a pair of massive, curved spines emanating from the lower sides of the head, and one curved spine on the top of its head. Unlike most pycnodontids, Coccodus species had a comparatively long body, giving the living animals a superficial resemblance to a scaly chimaera.
Charitopsis is an extinct genus of prehistoric marine ray-finned fish that lived during the lower Cenomanian. It was a relative of modern beaked salmons. It contains a single species, C. spinosus from the Sannine Formation of Lebanon. It is possibly related to the sympatric gonorynchid Charitosomus, although some anatomical traits are more similar to the Cenozoic gonorynchids.
Aethalionopsis is an extinct genus of prehistoric freshwater bony fish from the Early Cretaceous of western Europe. Formerly classified as a species of the elopiform Anaethalion, it is now known to be a relative of the modern milkfish (Chanos) in order Gonorhynchiformes. It was previously placed as a basal member of the suborder Chanoidei, but is now more often placed as a basal member of the subfamily Chaninae of the family Chanidae, placing it closer to the extant Chanos.
Anaethalion is an extinct genus of prehistoric marine and freshwater ray-finned fish related to modern tarpons and ladyfish. It is known from the Late Jurassic to the Early Cretaceous of Europe and northeasterrn Asia, roughly encompassing the Tethys Ocean.
Ctenothrissa is a prehistoric genus of ray-finned fish in the supposed order "Ctenothrissiformes".
Caeus is an extinct genus of prehistoric marine ray-finned fish, closely related to the modern milkfish. It contains a single species, C. leopoldi from the Early Cretaceous of the Pietraroja Plattenkalk, Italy. It is one of the largest teleosts known from the Pietraroja formation, and is known by only a single specimen.
This list of fossil fishes described in 2013 is a list of new taxa of placoderms, fossil cartilaginous fishes and bony fishess of every kind that have been described during the year 2013. The list only includes taxa at the level of genus or species.
Cheirothricidae is a family of extinct marine ray-finned fish, perhaps belonging to the Aulopiformes, although they are tentatively placed as indeterminate eurypterygians. They lived during the Upper Cretaceous and their fossil remains are found in the Middle East and Europe. They were characterized by very expanded even fins.
Tselfatiiformes is an extinct order of bony fishes from the infraclass Teleostei. The order represents the most important radiation of marine teleosts during the Cretaceous period. Fossils of tselfatiiforms are known from Europe, North America, central and northern South America, the Middle East and North Africa.
