Abstract: From 20 sections in the Tafilalt (eastern Anti-Atlas, Morocco), 13 early Emsian ammonoid species of the families Mimosphinctidae, Mimoceratidae, Teicherticeratidae, Mimagoniatitidae, and Auguritidae have been discovered. The following taxa are newly described: Chebbites n. gen., Chebbites reisdorfi n. sp., Chebbites undosus n. sp., Gracilites maghribensis n. sp., Palaeogoniatitinae n. subfam., Irdanites n. gen., Irdanites kaufmanni n. sp., Irdanites korni n. sp., Lenzites gesinae n. sp., Weyeroceras n. gen., Weyeroceras angustus n. sp. In addition, specimens of Erbenoceras solitarium, Metabactrites formosus, and Ruanites obliquecostatus are described and figured from Morocco for the first time. The ammonoid genera Convoluticeras, Erbenoceras, Mimosphinctes, Palaeogoniatites, Talenticeras, and Teicherticeras and the families Mimosphinctidae, Mimoceratidae, Teicherticeratidae, and Mimagoniatitidae are reviewed. Taskanites and Laganites are regarded as subjective junior synonyms of Convoluticeras. In Morocco, the early Emsian ammonoid succession differs from what can be expected from a phylogenetic point of view. Several species belonging to different families of various phylogenetic stages appear within one stratigraphical unit. In contrast to previous opinions however, Gyroceratites laevis appears stratigraphically earlier than Mimagoniatites fecundus, which agrees in this case with the phylogenetic succession of the taxa. Stratigraphical data from early Emsian ammonoids are still insufficient as basis for a more detailed stratigraphical subdivision of the early Emsian.
