Mesodactylites, which is sometimes considered to be a synonym of Nodicoeloceras is genus of ammonite that lived during early to middle Toarcian stage (Serpentinum to Bifrons ammonite Zones) of early Jurassic. Their fossils were found in southern and central Europe and northern Africa. It has evolved from Nodicoeloceras.
