Cephaloxenus

	Cephaloxenus ''Cephaloxenus'' is an extinct genus of prehistoric marine ray-finned fish that lived during the early Ladinian stage of the Middle Triassic epoch. It contains two species: * †''C. macropterus'' Brough, 1939 - Ladinian of Italy and Switzerland * †''C. squamiserratus'' Bürgin, 1992 - Ladinian of Italy It was often classified as a peltopleurid, but has more recently been classified as a perleidiform in its own monotypic family, Cephaloxenidae.
