Ctenothrissa is a prehistoric genus of marine ray-finned fish in the order Ctenothrissiformes.^[1] It contains a number of species known from the Late Cretaceous (middle Cenomanian to early Turonian) of England and Lebanon.^[2]^[3]

Taxonomy

The following species are known:

†C. microcephala (Agassiz, 1837) - Cenomanian to Turonian of England (English Chalk) (=Beryx microcephalus Agassiz, 1837)
†C. protodorsalis Gaudant, 1978 - Cenomanian of Lebanon (Haqel site of Sannine Formation)
†C. radians (Agassiz, 1837) - Cenomanian to Turonian of England (English Chalk) (=Beryx radians Agassiz, 1837)
†C. signifer Hay, 1903 - Cenomanian of Lebanon (Hadjoula site of Sannine Formation)
†C. vexillifer (Pictet, 1850) - Cenomanian of Lebanon (Haqel site of Sannine Formation) (=Beryx vexillifer Pictet, 1850) (type species)^[4]

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.^[5]^[6]
