Amiiformes

The extinct species of the Amiiformes can be found as fossils in Asia and Europe, but the bowfin is the last living species in the order. Amiiformes is therefore the last surviving order of Halecomorphi, the clade to which the bowfin and its fossil relatives belong. Other orders, such as the Parasemionotiformes, are all extinct. Halecomorphs, and its sister group Ginglymodi, belong to Holostei. Holosteans are the sister group of teleosteans, the group to which nearly all (i.e., 96%) living fishes belong to. Holosteans and Teleosts form a clade called Neopterygii. The following cladogram summarizes the evolutionary relationships of living and fossil Halecomorphs, and other neopterygians. }} Possible specimens of caturoids are known from the Late Triassic, with the earliest unambiguous members being known from the Early Jurassic. Amiiformes had spread to North America and Africa by the end of the Middle Jurassic, reaching an apex of diversity during the Early Cretaceous, during the Late Cretaceous and Cenozoic, the group declined until only a single genus, Amia, containing the bowfin remained. ==Taxonomy==
