Neolioceratoides

Neolioceratoides is genus of ammonites that lived during the Pliensbachian and Toarcian stages of early Jurassic. It has been considered to be a synonym of Lioceratoides, but cladistic analysis has shown, that this genus is not only valid, but they even belong to different subfamily, as Lioceratoides belongs to Harpoceratinae. Their fossils were found in Europe and northern Africa.
