Nouvelles recherches géologiques et malacologiques sur le Quaternaire de la province de Tarfaya (Maroc méridional)
Geobios, 9(5):529-549.
The province of Tarfaya located in the South of Morocco and West of Anti-Atlas is a part of the wide costal basin of West Sahara. Marine Pleistocene is poorly represented: three levels only can be numbered. Moghrebian, often attributed to Pliocene, possesses a doubtless quaternary gastropoda fauna. Messaoudian (Maarifian according to G. Lecointre) is known from a single site and contains a relatively warm fauna. Recent deposits, outcropping at less than +5 meters, cannot easily been determined by means of paleontology: they are Ouljian and perhaps Harounian-Rabatian. Compared with type-sections of Casablanca, an increase of southern influences in the faunas is noted: especially the Messaoudian shells present a rather obvious tropical type
