Enchodus is an extinct genus of aulopiform ray-finned fish related to lancetfish and lizardfish. Species of Enchodus flourished during the Late Cretaceous, and there is some evidence that they may have survived to the Paleocene or Eocene; however, this may just represent reworked Cretaceous material.
Ichthyodectiformes is an extinct order of marine stem-teleost ray-finned fish. The order is named after the genus Ichthyodectes, established by Edward Drinker Cope in 1870. Ichthyodectiforms are usually considered to be some of the closest relatives of the teleost crown group.
Axelrodichthys is an extinct genus of mawsoniid coelacanth from the Cretaceous of Africa, North and South America, and Europe. Several species are known, the remains of which were discovered in the Lower Cretaceous (Aptian-Albian) of Brazil, North Africa, and possibly Mexico, as well as in the Upper Cretaceous of Morocco (Cenomanian), Madagascar and France. The Axelrodichthys of the Lower Cretaceous frequented both brackish and coastal marine waters while the most recent species lived exclusively in fresh waters. The French specimens are the last known fresh water coelacanths. Most of the species of this genus reached 1 metre to 2 metres in length. Axelrodichthys was named in 1986 by John G. Maisey in honor of the American ichthyologist Herbert R. Axelrod.
Acanthomorpha is an extraordinarily diverse taxon of teleost fishes with spiny fin rays. The clade contains about one-third of the world's modern species of vertebrates: over 14,000 species.
The Paw Paw Formation is a geological formation in Texas whose strata date back to the late Albian stage of the Early Cretaceous. Dinosaur remains are among the fossils that have been recovered from the formation.
Anaethalion is an extinct genus of prehistoric marine and freshwater ray-finned fish related to modern tarpons and ladyfish. It is known from the Late Jurassic to the Early Cretaceous of Europe and northeasterrn Asia, roughly encompassing the Tethys Ocean.
The Mowry Shale is an Early Cretaceous geologic formation. The formation was named for Mowrie Creek, northwest of Buffalo in Johnson County, Wyoming.
Aegeridae is a family of fossil prawns, one of the earliest Mesozoic shrimp families. It contains the genera Aeger, Acanthochirana, Anisaeger and Distaeger. The main diagnostic character of Aegeridae is the presence of numerous spines or thin setae on the third maxilliped.
The Tlayúa Formation is an Early Cretaceous geological formation near Tepexi de Rodríguez, Puebla.

The Sannine Formation, also called the Sannine Limestone, is a Cretaceous geologic formation in Lebanon. It is a Konservat-Lagerstätte that contains a high diversity of well-preserved fish, reptiles, and invertebrates from the Tethys Ocean within its three main localities: Haqel, Hjoula, and Nammoura.
The Sierra Madre Formation is a geologic formation in Chiapas state, southern Mexico. It consists of marine dolomites and limestones. The formation dates to the Middle Cretaceous, spanning from the Aptian of the Early to the Cenomanian of the Late Cretaceous.
Aeger libanensis is a species of fossil prawn belonging to the family Aegeridae. These prawns had very long pereiopods.
Goulmimichthys is an extinct genus of ray-finned fishes in the family Pachyrhizodontidae. The genus, first described by Cavin in 1995, is known from various Turonian age formations. The type species G. arambourgi from the Akrabou Formation in the El Rachidia Province of Morocco, and other fossils described are G. gasparini of the La Frontera Formation, Colombia, and G. roberti from the Agua Nueva Formation of Mexico.
Bachea is an extinct genus of ray-finned fish that lived during the Late Cretaceous in what is now central Colombia, South America. The type species is Bachea huilensis, described in 1997 by María Páramo from the Turonian of Huila, Colombia.
Enchodontidae is an extinct family of aulopiform ray-finned fish known from the mid-late Cretaceous. It contains two subfamilies with several genera, including the famous Enchodus, with great morphological disparity among members of the group.
The Enchodontoidei are an extinct superorder of aulopiform fish known from the Early Cretaceous to the Eocene. They were among the dominant predatory marine fish groups in the Late Cretaceous, achieving a worldwide distribution. They were an extremely diverse group, with some developing fusiform body plans whereas others evolved elongated body plans with long beaks, superficially similar to eels and needlefish. They could also grow to very large sizes, as seen with Cimolichthys and Stratodus, the latter of which is the largest aulopiform known. Their most famous member is the widespread, abundant, and long-lasting genus Enchodus.
Xeneichthys is an extinct genus of teleost fish from the Albian El Doctor Formation in Hidalgo, Mexico. The type and only species is X. yanesi is known from multiple specimens, representing the entire body.
