Obsolete vertebrate taxa

A fish is an aquatic, anamniotic, gill-bearing vertebrate animal with a tough cranium to protect the brain, but lacking limbs with digits. Fish can be grouped into the more basal jawless fish and the more common jawed fish, the latter including all living cartilaginous and bony fish, as well as the extinct placoderms and acanthodians. In a break from the long tradition of grouping all fish into a single class (Pisces), modern phylogenetics views fish as a paraphyletic group that includes all vertebrates except tetrapods. In English, the plural of "fish" is fish when referring to individuals an

The Scorpaeniformes are a diverse order of ray-finned fish, encompassing species such as the stonefish, lionfish, and sculpins, but have also been called the Scleroparei. It is one of the five largest orders of bony fishes by number of species, with over 1,320.

Teleostomi (from Greek τελεος, complete + Greek στόμα, mouth) is an obsolete taxon of jawed vertebrates that supposedly includes the tetrapods, bony fish, and the wholly extinct acanthodian fish. Key characters of this group include an operculum and a single pair of respiratory openings, features which were lost or modified in some later representatives. The teleostomes include all jawed vertebrates except the chondrichthyans and the extinct class Placodermi.

thumb|right|Rutiodon, one of the aquatic and superficially crocodile-like [[phytosaurs]] Thecodontia (meaning 'socket-teeth'), now considered an obsolete taxonomic grouping, was formerly used to describe a diverse "order" of early archosaurian reptiles that first appeared in the latest Permian period and flourished until the end of the Triassic period. All of them were built somewhat like crocodiles but with shorter skulls, more erect pose and usually somewhat lighter. The group includes the ancestors of dinosaurs, pterosaurs, and crocodilians, as well as a number of extinct forms that did not

Pelteobagrus is a doubtful genus of bagrid catfishes found in eastern Asia. The taxonomy of this genus is unclear and many authorities treat it as a junior synonym of Tachysurus and the type species of the genus, is Silurus calvarius which is a synonym of Tachysurus sinensis.

Amphiarius is a genus of sea catfishes (order Siluriformes) of the family Ariidae. It includes two species, the Kukwari sea catfish, A. phrygiatus, and the softhead sea catfish, A. rugispinis.

Aspistor was a genus of sea catfishes found along the northeastern coast of South America, where they occur in marine, brackish, and fresh waters. The name is now a synonym of Notarius.

Dartfishes are a group of fish, formerly considered to be a subfamily, Ptereleotrinae, of goby-like fishes in the family Microdesmidae of the order Gobiiformes, Authorities now consider the species in the family Microdesmidae are within the Gobiidae, although the researchers do not define the taxonomic status of this grouping within that family. They are saltwater fish.

Euchiloglanis was a proposed genus of sisorid catfishes native to Asia. Species were moved to other genera once it was synonymised with Chimarrichthys.

The Dinichthyloidea is an extinct superfamily of placoderms, armored fish most diverse during the Devonian. However, the term is no longer in use, as modern cladistical methods have produced alternative phylogenetic trees of Brachythoraci with new subdivisions.
