This article aims to detail the construction and results of a new periodization of ceramic productions from megalithic sites in Senegal and The Gambia (8th-16th centuries CE ). For the first time there, this model is based on carefully documented stratigraphic contexts obtained on the necropolis of Wanar (Senegal). The intersection of typological and technological approaches reveals different productions, reflections of ceramic traditions, and distinct craft groups. In Wanar, the succession of these productions with specific morpho-functional characters could be correlated with the emergence of particular architectural styles. This periodization also integrates materials from previous excavations and thus offers a renewed reading of it. The distinction between ceramic vestiges anterior to the erection of monumental architectures and others fully participating in their ritual functioning leads to question both the status of ceramic productions and sites. This research finally contributes to integrating Senegambian pottery production into the broader context of medieval West Africa.
