An unranked group or infraclass of the fish subclass Neopterygii (class Actinopterygii) consisting of several fossil orders and the extant orders, Lepisosteiformes and Amiiformes. Members of the Holostei (holosteans) are descended from the older Chondrostei and in turn are ancestral to the great mass of modern bony fishes, the Teleostei. It is not certain whether holosteans evolved from a single stock or multiple stocks of the Chondrostei. See also: Actinopterygii; Osteichthyes; Teleostei
