Abstract
Latest Emsian to earliest Eifelian brachiopods from the Red Cliff at Hamar Laghdad (Tafilalt, eastern Anti-Atlas, Morocco) are described. The collection comprises 24 species. Among these, the genera Amoenospirifer, Cingulodermis, Eoreticularia, Hanusitrypa and Trigonatrypa are the most abundant. Four new species are erected: Dalejina aulacelliformis, Trigonatrypa drotae, Pinguispirifer kesskess and Cingulodermis pustulatus. Smooth or weakly plicate and small to medium- sized brachiopods prevail in the association of the Red Cliff. The association is very similar to some suggested shallow-water Emsian and Eifelian age brachiopod associations of the Barrandian area (Bohemia, Czech Republic) and Greifenstein (Eastern Rhenish Mountains, Germany); it indicates a similar environmental control in small coral biostromes or in this case between mudmounds.
