Abstract. Three succeeding assemblages of Early Tournaisian (Mississippian) ammonoids are described from Fezzou (Ma'der) in the Anti-Atlas of Morocco; they are, in ascending order, composed of the following genera: (1) Gattendorfia-Eocanites Assemblage: Acutimitoceras, Costimitoceras, Imitoceras, Kornia, Gattendorfia, Kazakhstania, and Eocanites; (2) Gattendorfia-Kahlacanites Assemblage: Acutimitoceras, Hasselbachia, Gattendorfia, Becanites, and Kahlacanites; and (3) Goniocyclus-Protocanites Assemblage: Globimitoceras, Imitoceras, Gattendorfia, Goniocyclus, Eocanites, and Protocanites. The following taxa are newly described: Globimitoceras rharrhizense n. sp., Acutimitoceras sarahae n. sp., A. endoserpens n. sp., A. pentaconstrictum n. sp., Costimitoceras aitouamar n. sp., Hasselbachia arca n. sp., Kornia citrus n. gen. n. sp., Gattendorfia lhceni n. sp., and G. gisae n. sp.
