From the eastern part of the Tafilalt (Anti‐Atlas, Morocco), rich assemblages of ammonoids of the Gattendorfia‐Eocanites Genozone are described. The detailed investigation of an outcrop near Mfis in the south‐eastern Tafilalt yielded a diverse fauna with 24 species, of which 13 are new. The genus Weyerella n. gen. is newly erected with Weyerella protecta n. sp. as type species. Furthermore, the following new species are described: Paragattendorfia aboussalamae n. sp., Acutimitoceras hollardi n. sp., Acutimitoceras posterum n. sp., Acutimitoceras mfisense n. sp., Acutimitoceras occidentale n. sp., Imitoceras oxydentale n. sp., Kazakhstania nitida n. sp., Zadelsdorfia debouaaensis n. sp., Weyerella minor n. sp., Eocanites simplex n. sp., Eocanites rtbeckeri n. sp., and Eocanites dkorni n. sp. The state of preservation of the ammonoids as limonitic steinkern specimens permits a detailed study of sutures and conch ontogeny.
