Tselfatiiformes
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.Joseph S. Nelson: ''Fishes of the World''. John Wiley & Sons, 2006, . The order appeared in the upper Albian on the coasts of Europe and North Africa and spread during the Cenomanian and Turonian on the Proto Atlantic to the coasts of northern South America, the Gulf of Mexico and into the Western Interior Seaway. In the Coniacian and Santonian they were very common in North American coastal waters, but disappeared from Europe and North Africa. A few species still lived in the Campanian in the Gulf of Mexico and they had died out by the Danian (early Paleocene). Features The genera and species of the Tselfatiiformes had a high-backed body. The dorsal fin took up most of ...

Tselfatia Formosa
''Tselfatia'' is an extinct genus of Cretaceous bony fish. Originally described from (and named after) Djebl Tselfat in Morocco, it has since been discovered at sites in several other countries ( Texas/USA, Germany, Mexico, Italy and the former Yugoslavia). The type species, ''Tselfatia formosa'', was named and described in 1944 by French paleontologist Camille Arambourg. A second species, ''T. dalmatica'', was named in 1980 from the Dalmatian Coast of Yugoslavia.Bardack, David & Teller-Marshall, Susan (1980).

Plethodidae
Plethodidae is an extinct family of teleost fish that existed during the Late Cretaceous period. Fossils are known from North America, North Africa, and Europe. Description Plethodids possessed thin, angelfish-like bodies and often had high dorsal fins which made them distinctive from other types of fish. Their skeletons were partially cartilaginous, though the amount varied from one species to another. Genera As of 2005, there are seventeen recognized genera in the family Plethodidae: * '' Bachea'' * '' Bananogmius'' * '' Dixonanogmius'' * '' Enischnorhynchus'' * '' Luxilites'' * '' Martinichthys'' * '' Moorevillia'' * '' Niobrara'' * ''Paranogmius ''Paranogmius'' is an extinct genus of prehistoric bony fish that lived during the Cenomanian.

Western Interior Seaway
The Western Interior Seaway (also called the Cretaceous Seaway, the Niobraran Sea, the North American Inland Sea, and the Western Interior Sea) was a large inland sea that split the continent of North America into two landmasses. The ancient sea, which existed from the early Late Cretaceous (100 million years ago) to the earliest Paleocene (66 Ma), connected the Gulf of Mexico, through the United States and Canada, to the Arctic Ocean. The two land masses it created were Laramidia to the west and Appalachia to the east. At its largest extent, it was deep, wide and over long. Origin and geology By Late-Cretaceous times, Eurasia and the Americas had separated along the south Atlantic, and subduction on the west coast of the Americas had commenced, resulting in the Laramide orogeny, the early phase of growth of the modern Rocky Mountains. The Western Interior Seaway may be seen as a downwarping of the continental crust ahead of the growing Laramide/Rockies mountain chain. Th ...

Euteleostei
Euteleostei, whose members are known as euteleosts, is a clade of bony fishes within Teleostei that evolved some 240 million years ago. It is divided into Protacanthopterygii (including the salmon and dragonfish) and Neoteleostei (including the lanternfish, lizardfish, oarfish, and Acanthopterygii). The cladogram is based on Near et al. (2012) and Betancur-Rodriguez et al. 2016. They explored the phylogeny and divergence times of every major lineage, analysing the DNA sequences of 9 unlinked genes. They calibrated (set actual values for) branching times in this tree from 36 reliable measurements of absolute time from the fossil A fossil (from Classical Latin , ) is any preserved remains, impression, or trace of any once-living thing from a past geological age.

Ostariophysi
Ostariophysi is the second-largest superorder of fish. Members of this superorder are called ostariophysians. This diverse group contains 10,758 species, about 28% of known fish species in the world and 68% of freshwater species, and are present on all continents except Antarctica. They have a number of common characteristics such as an alarm substance and a Weberian apparatus. Members of this group include fish important to people for food, sport, the aquarium industry, and research. Taxonomy The superorder is divided into two series, Anotophysi and Otophysi. However, in older literature, Ostariophysi was restricted only to the fish that are currently classified under Otophysi. Otophysi was coined in 1970 by Rosen and Greenwood to separate the traditional Ostariophysians from the added Gonorynchiformes. The superorder is classified below: *Series Anotophysi ** Gonorynchiformes, about 37 species *Series Otophysi (Euostariophysi) ** Cypriniformes (minnows and allies), about 4, ...

Otocephala
Otocephala is a clade of ray-finned fishes within the infraclass 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 Clupeiformes (herrings) and Ostariophysi, a group of other orders including Cypriniformes (minnows and allies), Gymnotiformes (knifefish), and Siluriformes (catfish). Otocephala may also contain Alepocephaliformes (slickheads), but as yet (2016) without morphological evidence. The clade is sister to Euteleostei which contains the majority of bony fish alive today. In 2015, Benton and colleagues set a "plausible minimum" date for the origin of 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 O ...

Clupeocephala
Teleostei (; Ancient Greek, Greek ''teleios'' "complete" + ''osteon'' "bone"), members of which are known as teleosts ), is, by far, the largest class (biology), infraclass in the class Actinopterygii, the ray-finned fishes, containing 96% of all neontology, extant species of fish. Teleosts are arranged into about 40 order (biology), orders and 448 family (biology), families. Over 26,000 species have been described. Teleosts range from giant oarfish measuring or more, and ocean sunfish weighing over , to the minute male anglerfish ''Photocorynus spiniceps'', just long. Including not only torpedo-shaped fish built for speed, teleosts can be flattened vertically or horizontally, be elongated cylinders or take specialised shapes as in anglerfish and seahorses. The difference between teleosts and other bony fish lies mainly in their jaw bones; teleosts have a movable premaxilla and corresponding modifications in the jaw musculature which make it possible for them to cranial kinesi ...
