Microdactylites, which is sometimes considered to be a synonym of Dactylioceras,^[2] is genus of ammonite that lived during early to middle Toarcian stage (Serpentinum to lower Bifrons ammonite Zones) of early Jurassic. Their fossils were found in England, France, Italy, Germany and Hungary. Species belonging to this genus were microconchs of Dactylioceras.^[1]
