Abandoned for a long time, the Landes de Gascogne benefit since 15 years by investigations suited to the forest. More than 20 cimeteries of the Early Iron Age have been excavated. Advances have been made about their organization and the study of the funeral practices. The latest, focused on the cremation and graves without tumulus, are adopted into all Aquitaine. As the documentation and the ceramic corpus grows, it seams more delicate to set-up typo-chronologies.
