The mackerel, tuna, and bonito family, Scombridae, includes many of the most important and familiar food fishes. The family consists of 51 species in 15 genera and two subfamilies. All species are in the subfamily Scombrinae, except the butterfly kingfish, which is the sole member of subfamily Gasterochismatinae.
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.
Congorhynchus is an enigmatic, likely polyphyletic genus of prehistoric marine ray-finned fish that was described by E. Darteville and E. Casier in 1949.
Enniskillenus is an extinct genus of prehistoric billfish from the Eocene of Europe. It contains a single species, E. radiatus from the Early Eocene-aged London Clay of England.
Argillichthys is an extinct marine lizardfish known from the Lower Eocene. It contains a single species, A. toombsi, from the Ypresian-aged London Clay Formation in England. It is known from a skull. It is thought to be a stem-member of Synodontidae.
Beerichthys is an extinct genus of prehistoric marine ray-finned fish. It contains a single species, Beerichthys ingens, that was a member of the Ypresian London Clay fauna of lower Eocene England.
Bramoides is an extinct genus of marine ray-finned fish that lived during the lower Eocene. It contains a single species, B. brieni, known from the London Clay.
Aulopopsis is an extinct genus of prehistoric marine ray-finned fish that lived during the lower Eocene. It is considered a relative of lizardfish in the order Aulopiformes, but its exact taxonomic placement is uncertain. Some authorities place it with the Aulopidae, while others place it with the Giganturoidae.
Argilloberyx is an extinct genus of prehistoric marine bony fish that lived during the lower Eocene. It contains one species, A. prestwichae, known from the London Clay Formation on the Isle of Sheppey, United Kingdom. It is considered a member of the family Berycidae.
Elopopsis is an extinct genus of marine ray-finned fish that lived during the Late Cretaceous of Europe, North Africa and North America. It was a member of the Crossognathiformes, in the family Pachyrhizodontidae.
Enchelurus is an extinct genus of prehistoric marine ray-finned fish that lived during the Late Cretaceous. It contains three species, known from the Cenomanian to Campanian of Europe and the Middle East.
Acrotemnus is an extinct genus of marine pycnodontid ray-finned fish known from Europe, North America, and Africa during the Turonian stage of the Upper Cretaceous. North American species could reach comparatively giant sizes for pycnodonts.
Balistomorphus is an extinct genus of prehistoric triggerfish during the early Oligocene epoch in what is now Canton Glarus, Switzerland, where fossils are known from the Matt Formation. It inhabited the marine environment of the Paratethys.
Acrognathus is an extinct genus of ray-finned fish belonging to the order Aulopiformes. Although no extensive systematic analysis has been performed, it is tentatively placed with the greeneyes in the family Chlorophthalmidae, making it the oldest representative of that family.
Ardiodus is an extinct genus of prehistoric marine scombroid fish from the late Paleocene (Thanetian) to the early Eocene (Ypresian). It contains a single known species, A. mariotti from the London Clay formation of the United Kingdom and the Ouled Abdoun Basin of Morocco.
Ctenothrissa is a prehistoric genus of marine ray-finned fish in the order Ctenothrissiformes. It contains a number of species known from the Late Cretaceous of England and Lebanon.
Dinelops is an extinct genus of marine ray-finned fish from the Late Cretaceous. It contains a single species, D. ornatus, from the Cenomanian of England. It was initially and often continues to be classified in the Osmeroididae, a family of extinct elopomorph fish that are placed in either the Albuliformes or Elopiformes. However, other studies place Osmeroides in the Albuliformes and Dinelops in the Elopiformes.
Cylindracanthus is an extinct, enigmatic genus of marine ray-finned fish with fossils known throughout North America, Europe, Asia and Africa from the Late Cretaceous to the late Eocene, with potential Oligocene records and a possible Miocene record also known. It is exclusively known from its distinctive partial remains, which are long cylindrical bony spines that are usually considered rostrum fragments, as well as some associated teeth. These spines are abundant & widespread throughout this timespan, and are useful indicators of a nearshore marine environment, but the taxonomic identity of the fish is still highly uncertain and debated.
Palimphyes is an extinct genus of marine ray-finned fish known from the Paleogene period. It was a euzaphlegid, an extinct family of scombroid fish related to the escolars and snake mackerels.
The Matt Formation is an Early Oligocene-aged marine geological formation that outcrops in the Glarus Alps of the Canton of Glarus, Switzerland. It is most notable for its fossiliferous slates found near Engi, known as the Engi slates, Glarner Schiefer or Glarner Fischschiefer, which contain the well-preserved fossils of fishes, birds, and sea turtles. The metamorphization of the rock has led to many of the fossils appearing somewhat distorted.
