Abstract
In the Zagros Basin (southwestern Iran), a 270 m thick section of shales, marls, marly limestones and limestones of the Kazhdumi Formation has yielded a diverse ammonite fauna which allowed for a detailed biostratigraphic zonation. Aptian ammonites of the families Deshayesitidae and Parahoplitidae occur indicating a latest early to late Aptian age. Albian Douvilleiceratidae, Lyelliceratidae and Brancoceratidae indicate early, middle and late Albian age. Their range and generic and specific determinations are tabulated and illustrated.
