Two Middle Paleolithic sites have been excavated on the territory of Corbie (Somme), before the laying of a gas pipeline. Several small lithic assemblages have been found within the complex of soils from the Weichselian Early Glacial. They feed the debate on the variability of the lithic industries at the beginning of the last glaciation, especially by the discovery of a hand-axe in a stratigraphic horizon correlated with stage 5c of the marine isotopic curve.
