A new ammonoid fauna from the <i>Gattendorfia-Eocanites</i> Genozone of the Anti-Atlas (Early Carboniferous; Morocco)

| Summary: | From the eastern part of the Tafilalt (Anti-Atlas, Morocco), rich assemblages of ammonoids of the <i>Gattendorfia-Eocanites</i> 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 <i>Weyerella</i> n. gen. is newly erected with <i>Weyerella protecta</i> n. sp. as type species. Furthermore, the following new species are described: <i>Paragattendorfia aboussalamae</i> n. sp., <i>Acutimitoceras hollardi</i> n. sp., <i>Acutimitoceras posterum</i> n. sp., <i>Acutimitoceras mfisense</i> n. sp., <i>Acutimitoceras occidentale</i> n. sp., <i>Imitoceras oxydentale</i> n. sp., <i>Kazakhstania nitida</i> n. sp., <i>Zadelsdorfia debouaaensis</i> n. sp., <i>Weyerella minor</i> n. sp., <i>Eocanites simplex</i> n. sp., <i>Eocanites rtbeckeri</i> n. sp., and <i>Eocanites dkorni</i> n. sp. The state of preservation of the ammonoids as limonitic steinkern specimens permits a detailed study of sutures and conch ontogeny.

Aus dem östlichen Tafilalt (Anti-Atlas, Marokko) wird eine Ammonoideen-reiche Abfolge aus der <i>Gattendorfia-Eocanites</i> Genus-Zone beschrieben. Ein im Detail untersuchtes Profil bei Mfis hat eine individuenreiche und diverse pelagische Fauna mit 24 Arten geliefert, von denen 13 neu sind. Die Gattung <i>Weyerella</i> n. gen. wird mit <i>Weyerellaprotecta</i> n. sp. als Typusart aufgestellt. Weitere neue Arten sind: <i>Paragattendorfiaaboussalamae</i> n. sp., <i>Acutimitocerashollardi</i> n. sp., <i>Acutimitocerasposterum</i> n. sp., <i>Acutimitocerasmfisense</i> n. sp., <i>Acutimitocerasoccidentale</i> n. sp., <i>Imitocerasoxydentale</i> n. sp., <i>Kazakhstanianitida</i> n. sp., <i>Zadelsdorfiadebouaaensis</i> n. sp., <i>Weyerellaminor</i> n. sp., <i>Eocanitessimplex</i> n. sp., <i>Eocanitesrtbeckeri</i> n. sp. und <i>Eocanitesdkorni</i> n. sp. Die in Limonit erhaltenen Steinkerne erlauben eine Detailuntersuchung der Lobenlinien und der Gehäuse-Ontogenie.
