Gracilignathichthys is an extinct genus of prehistoric marine ray-finned fish that lived during the late Anisian to the early Ladinian stage of the Middle Triassic epoch in what is now Europe.[2][1][3] It contains a single species, G. microlepis, known from the Besano Formation on the border of Italy and Switzerland.[2][4] Teeth reminiscent of Gracilignathichthys are also known from the Muschelkalk of Luxembourg.[5] It is considered a pholidopleuriform of uncertain affinities.[6]
