type species) These
Teleostei are only known from
fossils. While they are sometimes included in the
superorder Acanthopterygii or
Protacanthopterygii, this is neither well-supported, nor is the
monophyly of the "Ctenothrissiformes" robustly established. It has instead been suggested by some authors that the supposed order is a
paraphyletic assemblage of ancient moderately advanced Teleostei; for example, the ctenothrissiform
Aulolepis is found by some authors to be an
aulopiform. ==Gallery==
