Résumé
Understanding the contribution of fish to the human dietis an important debate in past population studies as it implies specific organization (e.g. adapted techniques, gender-based activities?) and relationship with the local or sublocal environments (e.g. mobility, seasonal-based exploitation). In the Paris Basin, the role of fish has been discussed mainly from rare but obviousarchaeologicalremains such as fish bones or hooks. Previous isotopic data from Neolithic human bone bulk collagen highlighted the potential of freshwater resources in protein diet but were not able to quantify it or even confirm its role. In this study we conducted, for the first time on early farmers from France,compound specific isotope analysis on bone collagen amino acids (CSIA-AA). Results indicate a particularly high trophic level of some humans with protein intake mainly based on terrestrial animal resources (domestic cattle and pig), while others rather havea plant-based diet. Freshwater resources appeared to be not significant and several possible food combinations are discussed. Pig particularly appears more herbivorous than previously assumed and has possibly consumed manured cereals from human food waste.
