Chitinozoaires Ashgilliens de l'Anti-Atlas (Maroc)

Thirty-three species of Chitinozoans are recorded in the Upper Ktaoua and in the Lower Deuxième Bani Formations (Anti-Atlas, Morocco). These two lithological units have been referred to the upper part of the Ashgill Series based on Trilobite, Brachiopod, and Echinoderm evidence. Strong affinities with North American Chitinozoan assemblages are noted.
