Ioscion morgani is an extinct prehistoric bony fish that lived during the Upper Miocene subepoch of what is now Southern California. [1] It is primarily known from incomplete fossils, such as the holotype, which consists of a broken backbone. Although the head is unknown, enough of the animal's anatomy suggests a relationship with the jackfishes of Carangidae. [2]
Echidnocephalus troscheli is an extinct, prehistoric halosaur. Fossils are found from Campanian strata of Westphalia, Germany. The complete and incomplete fossil specimens that have been found suggest an animal already looking very much like modern halosaurs.
Laytonia is an extinct genus of prehistoric halosaur that lived in deep water off the North American Pacific Coast from the Zemorrian Epoch until during the Upper Miocene subepoch, when tectonic uplift effectively destroyed the genus' habitat by making the deep water too shallow.
Deprandus is an extinct genus of prehistoric bony fish that lived during the Upper Miocene subepoch.
Africentrum is an extinct genus of prehistoric bony fish that lived during the Upper Miocene subepoch.
Xyne is an extinct genus of prehistoric herring that lived during the Upper Miocene subepoch.
Bolbocara gyrinus is an extinct rattail that lived during the Upper Miocene subepoch of Southern California. It may be related to the extant genus Bathygadus.

Lompoquia retropes is an extinct genus of ray-finned fishes belonging to the family Sciaenidae, the drums. These fishes lived what is now Southern California during the Upper Miocene subepoch.

Eriquius is an extinct genus of prehistoric bony fish that lived during the Upper Miocene subepoch.
Chalcidichthys malacapterygius is an extinct prehistoric manefish that lived during the Upper Miocene of Southern California. It is assumed to have preyed on siphonophores, like its living relatives.

Lophar miocaenus is an extinct bony fish almost identical in form to the living bluefish, Pomatomus saltatrix, differing in its dentition, which consisted of "thick, conical subequal teeth" instead of the sharp, slender teeth and canines seen in bluefish. L. miocaenus lived during the Upper Miocene subepoch of Southern California.
Absalomichthys velifer is an extinct, prehistoric manefish that lived during the Upper Miocene of what is now Southern California. Its dorsal fin was huge in comparison with living species.
