The beardfishes consist of a single extant genus, Polymixia, of deep-sea marine ray-finned fish named for their pair of long hyoid barbels. They are classified in their own order Polymixiiformes. But as Nelson says, "few groups have been shifted back and forth as frequently as this one, and they were recently added to Paracanthoptergii". For instance, they have previously been classified as belonging to the Beryciformes. They are of little economic importance.
Berycopsis is an extinct genus of marine ray-finned fish from the Late Cretaceous period. Fossils are known from England, Germany, and Lebanon. A potential specimen is known from the Czech Republic.
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.
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.
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.
Caproberyx is an extinct genus of marine acanthomorph ray-finned fish, possibly a holocentrid, from the Late Cretaceous.
Bananogmius is an extinct genus of marine ray-finned fish that was found in what is now North America and Europe during the Late Cretaceous, from the Cenomanian to the Santonian. It lived in the Western Interior Seaway, which split North America in two during the Late Cretaceous, as well as the proto-North Sea of Europe.
Aulolepis is an extinct genus of prehistoric marine ray-finned fish that lived during the upper Cenomanian and early Turonian. It contains a single species, A. typus from the Chalk Group of the United Kingdom and the Hesseltal Formation of Germany.
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.
Araripichthys is an extinct genus of marine ray-finned fish that lived from the Aptian to Coniacian stages of the Cretaceous period. The genus is named after the Araripe Basin, where it was found in the Crato and Santana Formations. Other fossils of the genus have been found at Goulmima in Morocco, the Tlayua Formation of Mexico and the Apón Formation of Venezuela.
Ctenocephalichthys is an extinct genus of prehistoric marine ray-finned fish, generally considered a holocentriform, that lived during the Late Cretaceous. It is known from Cenomanian to the Santonian of Lebanon.
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.
Barcarenichthys is an extinct genus of prehistoric marine ray-finned fish that lived during the Late Cretaceous. It contains a single species, B. joneti, from the late Cenomanian of Portugal.
Adriacentrus is an extinct genus of prehistoric marine bony fish that lived in the Turonian in what is now Croatia. It contains a single species, A. crnolataci. Formerly considered a beryciform fish, it is now known to be more closely related to the squirrelfish (Holocentridae).
Berycopsia is an extinct genus of beardfish that lived during the Turonian stage of the Late Cretaceous. It contains a single species, B. inopinnata, that inhabited marine habitats of the Tethys Sea around what is now Croatia.
Clupavus is an extinct genus of marine ray-finned fish that lived during the middle of the Cretaceous period. It is known from North Africa, Europe, Brazil, and possibly North America.

The list only includes taxa at the level of genus or species.
Armigatus is an extinct genus of marine clupeomorph fishes belonging to the order Ellimmichthyiformes. These fishes lived in the Cretaceous ; their fossil remains have been found in Mexico, Europe, the Middle East and North Africa, suggesting the genus ranged across the Tethys Sea.
The Hesseltal Formation or Blackcoloured Formation is a Late Cretaceous geological formation from northern Germany. It consists of lithified marls and limestone, with a unique series of black shales deposited in anoxic conditions during the Cenomanian-Turonian boundary event.
