As regards stratigraphy, important discrepancies were found between the pottery analysis based on the sedimentary complexes already established, and the accepted ceramic chrono-typology. The correlation between pottery and sedimentary complexes remains problematic and it was decided not to make reference to it so long as no new elements came to light. However, ceramostratigraphy is an alternative model for the study of deposits of artefacts that provides, a posteriori, a tool for the archaeological reading of stratigraphy.
