Mesoclupea showchangensis is an extinct ichthyodectiform ray-finned fish that lived in freshwater environments in what is now China during the Early Cretaceous epoch. It differs from its sister genus, Chuhsiungichthys , primarily by having a more posteriorly-placed dorsal fin.
Ceratoichthys pinnatiformis is an extinct species of lookdown-like prehistoric jackfish that lived during the Lutetian epoch, of the Middle Eocene of Monte Bolca, Italy.
Plectocretacicus is an extinct genus of prehistoric ray-finned fish that lived during the lower Cenomanian. It contains a single species, P. clarae. Plectocretacicus is the earliest known member of the order Tetraodontiformes.
Neopholidophoropsis is an extinct genus of prehistoric ray-finned fish that lived during the Aptian stage of the Early Cretaceous epoch.
Lissoberyx is an extinct genus of prehistoric ray-finned fish belongon to the family Trachichthyidae. Lissoberyx is a trachichthyid, but it shows more resemblance to the holocentrids than any other trachichthyid.
Macrepistius is an extinct genus of prehistoric ray-finned fish that lived during the Albian stage of the Early Cretaceous epoch.

Acrotemnus is an extinct genus of prehistoric ray-finned fish that lived during the Late Cretaceous epoch.
Polygyrodus is an extinct genus of prehistoric ray-finned fish that lived during the Late Cretaceous epoch. The name is a combination of the Greek words poly (many), gyro (round), and odoy (tooth).

Madariscus robustus is an extinct prehistoric freshwater ray-finned fish, of the family Archaeomaenidae, that lived during the Jurassic period on Australia. Its fossils, originally described as "Archaeomaene robustus," have been found on the Colalura Sandstone.
Opsithrissops is an extinct genus of prehistoric bony fish that lived during the Thanetian stage of the Paleocene epoch. It is a small 100 centimetres (3.3 ft) nektonic opportunistic carnivore in the family Osteoglossiformes which includes other bony-tongues such as the extant species of Arowana and Arapaima. It hunted small invertebrates and fish similarly to today's trout and became a Paleogene keystone species in many habitats before its disappearance from the fossil record.
Koonwarria manifrons is an extinct prehistoric ray-finned fish that lived in a polar lake in what is now Koonwarra, Victoria, Australia. Fossils have been retrieved from the Strzelecki Group.

Osmeroides is an extinct genus of prehistoric ray-finned fish from the Cretaceous.

Chuhsiungichthys is an extinct genus of ichthyodectiform ray-finned fish that lived in freshwater environments in what is now Yunnan, China, and Kyushu, Japan, during the Cretaceous. It differs from its sister genus, Mesoclupea, primarily by having a comparatively more anteriorly-placed dorsal fin.
