Abstract : A revision of the ammonites from the Bakony Mountains (Hungary) based on collections of the Geological Institute of Hungary (MAFI) in Budapest, revealed the following sequence of faunas. The youngest Campanian ammonites from the South Bakony are three specimens of Pachydiscus (P.) praecolligatus COLLIGNON, 1955 from the Sumeg area; this is a typical Campanian species. Two specimens of former “Lower Maastrichtian Pachydiscus neubergicus (HAUER)” from Haraszt quarry have been re-determined as Early Campanian Eupachydiscus levyi (GROSSOUVRE, 1894). The fragmentary specimen of Mortoniceras sp. has been determined as Texanites (Texanites) sp. from the Upper Santonian. Two ammonite zones can be recognised for these sequences: Texanites sp. (Santonian) and Eupachydiscus levyi (Lower Campanian)
