[Helminth eggs: trace elements of neolithic and paleolithic parasitosis on French sites].

On the neolithic site of Chalain (Jura, France), the analysis of human coprolites has revealed the presence of many well preserved eggs of Helminths: eggs of Trichuris spP., Capillaria spp., Fasciola hepatica, Diphyllobothrium spP. In the paleolithic picturial sanctuary of the Grande Grotte at Arcy-sur-Cure (Yonne, France), eggs of Ascaris spP. have been discovered. The presence of these parasits open a new way of search about the knowledge of ancient populations.
