Contribution à la connaissance de la faune ichthyologique des phosphates du Maroc

Fifteen new forms are described from the phosphate beds of Ouled Abdoun, Morocco. They have permitted refinement of C. Arambourg’s proposed stratigraphic correlation with the Anglo-Franco Belgian basin. The presence of a discontinuity between the Maestrichtian and the « Montian » (sensu Arambourg) is demonstrated, as also is the existence of a cool climatic phase in the Montian of Morocco
