Aulopiformes is a diverse order of marine ray-finned fish consisting of some 15 extant and several prehistoric families with about 45 genera and over 230 species. The common names grinners, lizardfishes and allies, or aulopiforms are sometimes used for this group. The scientific name means "Aulopus-shaped", from Aulopus + the standard fish order suffix "-formes". It ultimately derives from Ancient Greek aulós + Latin forma, the former in reference to the elongated shape of many aulopiforms.
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.
Apateodus is a genus of prehistoric marine ray-finned fish which was described by Woodward in 1901. It was a relative of modern lizardfish and lancetfish in the order Aulopiformes, and one of a number of prominent nektonic aulopiforms of Cretaceous marine ecosystems.
Cyranichthys is an extinct marine aulopiform fish genus from Cenomanian-aged marine strata of what is now the Kipala formation in the Congo, Belgium and The Netherlands. The type species C. ornatissimus is known from Africa, while the newer discovered species, C. jagti, is known from Europe.
Stratodus is a genus of giant prehistoric aulopiform fish found in Cretaceous-aged marine strata of Kansas, Alabama, Morocco, Israel, and Niger, South Dakota, Jordan. It has also been found in the Tamaguélelt Formation of Mali, dating to the Lower Eocene, indicating that Stratodus survived the Cretaceous-Paleogene extinction event. This sleek fish has an upper jaw filled with multiple rows of tiny teeth and was the largest aulopiform, reaching 5 meters in length.
Anguillavus is an extinct genus of basal marine eel that lived during the upper Cenomanian of Lebanon. It is the only known member of the family Anguillavidae. Its primitive nature compared to extant eels is indicated by it still retaining its pelvic fins, which have been lost in modern eels.
The El Doctor Formation is a geologic formation in Mexico. It preserves fossils dating back to the Albian and Cenomanian stages of the Cretaceous period.

Veridagon avendanoi is an extinct aulopiform ray-finned fish related to species of Enchodus from the Cenomanian-aged Cintalapa Formation, exposed in El Chango Quarry, Chiapas, Mexico. Its original generic name was Dagon; however, this name was preoccupied by a group of South American butterflies. The generic name was eventually amended to Veridagon.

Enchodontidae is an extinct family of aulopiform 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 Dercetidae are an extinct family of aulopiform fish that are known from the Late Cretaceous to the Paleocene. They are among the many members of the diverse, extinct suborder Enchodontoidei, which were dominant during the Cretaceous. Many genera evolved a very slender body plan with elongated jaws, closely converging on modern needlefish.
Ichthyotringidae is an extinct family of aulopiform fish known from the Early to Late Cretaceous. It is one of the Enchodontoidei, a diverse group of aulopiforms that were dominant marine fish during the Cretaceous.
Halecidae is an extinct family of aulopiform fish known from the Cretaceous. It is one of the Enchodontoidei, a diverse group of aulopiforms that were dominant marine fish during the Cretaceous.
Lamprimorpha is a superorder of marine ray-finned fishes, representing a basal group of the highly diverse clade Acanthomorpha. Represented today only by the order Lampriformes, recent studies have recovered other basal fossil species of the group dating as far back as the Cenomanian stage of the Late Cretaceous. Some of these fossil taxa, such as the paraphyletic genus Aipichthys, are among the oldest known fossil acanthomorphs, and overall they appear to have been a major component of the marine fish fauna at that time. Lamprimorpha is thought to be the sister group to the superorder Paracanthopterygii, which contains cod, dories, and trout-perches.
