Robustichthys is an extinct genus of ray-finned fish from the Middle Triassic period, contains only one species R. luopingensis.[1][2] It belonged to the clade Halecomorphi, which were once diverse during the Mesozoic Era, but which are today represented by only a single species, the bowfin. Halecomorphs are holosteans, a clade which first appeared in the fossil record during the Triassic.[3]
