Abstract:  From the eastern part of the Tafilalt (Anti-Atlas, Morocco), rich assemblages of ammonoids of the Gattendorfia-EocanitesGenozone 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.
