As of September 2016, the International Union for Conservation of Nature (IUCN) lists 65 extinct fish species, 87 possibly extinct fish species, and six extinct in the wild fish species. [ 1 ] [ 2 ] Cartilaginous fish
The International Code of Zoological Nomenclature (ICZN) is a widely accepted convention in zoology that rules the formal scientific naming of organisms treated as animals. It is also informally known as the ICZN Code, for its formal author, the International Commission on Zoological Nomenclature (which shares the acronym "ICZN"). The rules ...
Brownstein, Near & Dearden (2024) reconstruct the evolutionary history of holocephalans, and argue that, while key features of the holocephalan body plan evolved in the Paleozoic, the group entered deep ocean waters and diversified there only after the Cretaceous–Paleogene extinction event. [40] Böttcher (2024) argues that preservation of ...
Enchodontidae is an extinct family of aulopiform ray-finned fish known from the mid-late Cretaceous (Albian to Maastrichtian).It contains two subfamilies with several genera, including the famous Enchodus, with great morphological disparity among members of the group.
Critically endangered (CR) species face an extremely high risk of extinction in the wild. As of December 2021, the International Union for Conservation of Nature (IUCN) lists 673 critically endangered amphibian species, including 146 which are tagged as possibly extinct. [1] [2] 9.2% of all evaluated amphibian species are listed as critically ...
Haikouichthys / ˌ h aɪ k u ˈ ɪ k θ ɪ s / is an extinct genus of craniate (animals with notochords and distinct heads) that lived 518 million years ago, during the Cambrian explosion of multicellular life. The type species, Haikouichthys ercaicunensis, was first described in 1999. [2]
Iniopteryx was a chimaera-like fish, described as "plump".It is known that the species average size was around half a meter in length. While the species had specialized spines and fins superficially similar to that of a flying fish, there is much speculation about whether it could glide like a flying fish, or was actually benthic.
A few living forms, such as the coelacanth are also referred to as prehistoric fish, or even living fossils, due to their current rarity and similarity to extinct forms. Fish which have become recently extinct are not usually referred to as prehistoric fish. Lists of various prehistoric fishes include: List of prehistoric jawless fish; List of ...
