Macropetalichthys is a genus of placoderm fish, named by Norwood and Owen in 1846; the name "Macropetalichthys" means "armor-plated fish".[2][3] It was assigned to Arthrodira by Woodward (1891); and to Petalichthida by Sepkoski (2002). Several species have been referred to Macropetalichthys, but the best known is the type species, M. rapheidolabis, from the Jeffersonville Limestone of Indiana, USA, and Columbus Limestone of Ohio, USA.
