Crossognathiformes
Crossognathiformes is an extinct order of ray-finned fish that lived from the Late Jurassic to the Eocene. Its phylogenetic placement is disputed; some authors have recovered it as part of the teleost stem group, while others place it in a basal position within crown group Teleostei.

Apsopelix
''Apsopelix'' is an extinct genus of ray-finned fish that existed about 95-80 million years ago in the shallow waters of the Western Interior Seaway, Hudson Seaway, England, France, and Japan. Description ''Apsopelix'' was a small teleost, reaching lengths of 23-27 centimeters (9-10 inches). Fossils possess long gill rakers, which are indicative of a microphagous lifestyle, and evidence of a long gut alongside a robust body show that Apsopelix likely fed on plankton. Classification The genus ''Apsopelix'' has a confusing taxonomic history, with several genera being lumped into it over time. Fossils of the genus found in new locations or preserved unusually would be given distinct genus names, and the holotype specimen was misattributed as a species of Calamopleurus. The genus has also been assigned to a plethora of different teleost groups, such as Mugilidae, Clupeidae, Elopoidei, Clupeomorpha, Osteoglossomorpha, Percesoces, Crossognathidae, Syllaemidae, Pelycorapidae, A ...

Ray-finned Fish
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 Actinoptery ...
