Abstract: The Toarcian–Aalenian Ammonoidea fauna of the Gerecse Mts belongs to the Mediterranean Province of the Mediterranean–Caucasian Realm. In this paper the Hammatoceratinae, represented by 7 genera (Geczyceras, Crestaites, Hammatoceras, Bredyia, Planammatoceras, Accardia, Pseudaptetoceras) and 31 species, are described and figured, and their stratigraphic distribution is recorded. Three new species: Geczyceras martinezae n. sp., Geczyceras galaczi n. sp., and Crestaites szentei n. sp. are introduced. Taxonomic problems of the subfamily are briefly discussed; faunas of various localities of the NW European and Mediterranean Provinces are compared.
