The terminal infilling of the Ferlo valley consists of a decimetric layer containing marine or brackish fauna (Tympanotomus fuscatus, Tagelus angulatus). This implies contact with the sea several months per year during a minimum period of five years (time necessary for the Tympanotomus growth) and possibly one century or more. This formation is the consequence of a marine invasion that penetrated the lower Valley of the Senegal and Ferlo rivers up to 150 km above the present boundary at 1545 and 1980 years BP. This saline invasion depended on a sea level rise and/or a lowering of fresh water input due to climatic drought.
