Abstract

Abstract Emsian to Frasnian crinoids are described from pelagic facies of the eastern part of the Dra Valley (Tata area), western Anti-Atlas Mountains, southern Morocco. The crinoids show only minor relationship with previously described crinoids from the Tafilalt and Ma'der areas of the eastern Anti-Atlas. The differences are judged to reflect the different environments of these areas. The Dra Valley hexacrinids show greater affinity with European faunas, whereas the amabilicrinids show greater affinity with North American taxa. New taxa described are Hexacrinites chenae sp. nov., Dracrinus crenulatus gen. and sp. nov., Coquinacrinus revimentus gen. and sp. nov, and Embolocrinus quadruus gen. and sp. nov.
