Arietitidae ✝
| Description | Arietitidae is a family of true ammonites that make up part of the superfamily Psiloceratoidea. They comprise medium-size to large or gigantic genera which in general are strongly ribbed, tuberculate in some, with keeled or grooved and keeled venters, and well differentiated ammonitic sutures. The aptycus is single valved with a shiny, concentrically striated surface.
