An interdisciplinary research project is currently underway to understand the social, economic, and territorial organization of Middle and Recent Neolithic societies in the Saint-Gond Marshes region of Marne, France. Led by Rémi Martineau of CNRS UMR 6298 ArTeHis, the project brings together several institutions, including Inrap, UMR 6249 Chrono-environment, UR 3795 GEGENA, UMR 7193 ISTeP, and MSH Dijon. Researchers are using data from Neolithic habitats, flint mines, and collective burials to study how these communities organized their territories, practiced funerary rituals, managed their lithic (stone tool) economy, and interacted with their environment. The Saint-Gond Marshes region is home to more than 500 Neolithic sites and site indicators, making it one of the most significant archaeological areas in Europe. The variety of sites—ranging from flint mines to enclosures and burial grounds—provides a comprehensive dataset for analysis. New excavations are planned on Middle and Recent Neolithic habitats to build on existing research from the Val-des-Marais "Le Pré à Vaches" site, which includes both a habitat and an enclosure. The project is divided into four study zones, each with specific excavation and drilling projects. Zone I focuses on the Val-des-Marais "Le Pré à Vaches" habitat and enclosure. Zone II includes the Vert-Toulon "Les Grands Limons" habitat and the Coizard "Lessard" flint mine. Zone III involves the Fèrebrianges "Le Bois de la Fortelle" habitat and enclosure, while Zone IV covers the Villevenard "La Vieille Andecy" habitat and the Villevenard "La Pente du Moulin" flint mine. Biological anthropology studies of human remains found in hypogea (underground burial chambers) by Joseph de Baye will help researchers understand the characteristics of the populations that lived in the region. Researchers will also continue analyzing furnishings from previous excavations. The flint economy is a central focus, as it provides key insights into territorial organization. By cross-referencing domestic and funerary data across the region, the team aims to reconstruct the economic and social structures of these Neolithic communities. The study will examine flint production and the technical skills involved, mapping the stages of operational chains from mining sites to workshops and habitats. New excavations of flint mines will help researchers better understand how flint was extracted and processed. By comparing the volume of flint extracted with the environmental availability, the team will estimate the intensity of resource exploitation. Using petrographic and geochemical analyses, such as LA-ICP-MS/MS, they will trace the diffusion areas and circulation networks of flint. The Saint-Gond Marshes region's proximity to vast marshes allows for paleoenvironmental studies, helping researchers evaluate the impact of human activity and analyze the relationship between Neolithic communities and their natural surroundings.
