The Gironde estuary in SW France is the largest in Western Europe and has attracted human populations since prehistoric times. From the 1970s to the 1990s, intense archaeological research was undertaken on the long and highly dynamic coastline just south of the estuary mouth. In recent years, the combined action of increased coastal erosion and human pressure has proved a serious threat to the integrity of archaeological sites in the area. As a consequence, a whole array of previously unrecorded archaeological remains across the intertidal zone and coastal strip is being exposed. In this context, innovative interdisciplinary research since 2014 is yielding new information about the settlement and landscape dynamics and about the long-term interaction between human societies and the environment. The sedimentary context and the exceptional preservation conditions of organic remains have made possible a multi-proxy approach combining archaeological, geomorphological, palaeobiological, and archaeoentomological methods. In this paper we discuss the different approaches and the way they jointly contribute to the project. The results obtained so far from this multi-proxy approach challenge the traditional view of the historic occupation and the landscape dynamics around the Gironde estuary from prehistoric times to antiquity. They show that the intense occupation of this area during certain periods of human history is related to the development of marshy environments, which can now be analyzed at higher temporal resolution owing to this approach.

Sheep remains constitute the main archaeozoological evidence for the presence of Early Neolithic human groups in the highlands of the Southern Pyrenees but understanding the role of herding activities in the Neolithisation process of this mountain ecosystem calls for the analysis of large and well-dated faunal assemblages. Cova de Els Trocs (Bisaurri, Huesca, Spain), a cave located at 1564 m a.s.l on the southern slopes of the Central Pyrenees, is an excellent case study since it was seasonally occupied throughout the Neolithic (ca. 5312-2913 cal. BC) and more than 4000 caprine remains were recovered inside. The multi-proxy analytical approach here presented has allowed us to offer new data elaborating on vertical mobility practices and herd management dynamics as has not been attempted up until now within Neolithic high-mountain sites in the Iberian Peninsula. For the first time, δ18O and δ13C stable isotope analyses offer direct evidence on both the regular practice of altitudinal movements of sheep flocks and the extended breeding season of sheep. Autumn births are recorded from the second half of the fifth millennium cal. BC onwards. Age-at-death distributions illustrate the progressive decline in caprine perinatal mortality together with the rising survival rate of individuals older than six months of age and the larger frequency of adults. This trend alongside the 'off-season' lambing signal at the implementation of husbandry techniques over time, probably aiming to increase the size of the flocks and their productivity. Palaeoparasitological analyses of sediment samples document also the growing reliance on herding activities of the human groups visiting the Els Trocs cave throughout the Neolithic sequence. In sum, our work provides substantial arguments to conclude that the advanced herding management skills of the Early Neolithic communities arriving in Iberia facilitated the anthropisation process of the subalpine areas of the Central Pyrenees.

Face a la destruction ineluctable des derniers niveaux archeologiques de la Lede du Gurp par l’erosion littorale, une operation de fouille a ete menee en 2014. Ce site de reference presente une stratigraphique exceptionnelle, presque continue du 9e au 1er millenaire av. J.-C. Plusieurs tranchees de diagnostic ont permis d’identifier les differentes phases d’occupation dont la chronologie a ete etablie a partir du croisement des etudes du mobiliers et de dates radiocarbones. La decouverte de structures amenagees (fosses, clayonnages) et d’abondants rejets (ceramiques, faune) indiquent une frequentation des lieux importante a la fin du Neolithique moyen (Chasseen), au Neolithique recent I (culture Matignons) et II (Peu-Richard maritime) -probablement liee a l’exploitation du sel-, ainsi qu’au Bronze ancien-moyen. Une etude paleoparasitologique a pu etre realisee grâce a la conservation des elements organiques en milieux humides.

Paleoparasitological analyses were conducted on samples from the Neolithic lakeside settlement of La Draga in Spain (5320–4980 BC). Conventional microscopic analysis revealed the presence of tapeworms (genus Taenia/Echinoccocus and Diphyllobothrium), roundworms (genus Trichuris, Capillaria, and Ascaris), rumen fluke (genus Paramphistomum), and Acanthocephalan (genus Macracanthorhynchus). In addition, genetic analysis demonstrated the presence of the lancet liver fluke (Dicrocoelium dendriticum) and the human pinworm (Enterobius vermicularis) at the site. These results represent the first parasitological data from a Neolithic lakeside settlement related to the Cardial Pottery Culture. Some parasites are comparable with those retrieved from Neolithic lakeside sites studied in France, Germany, and Switzerland, which stem from and are posterior to the Linear Band Keramic Culture. However, some taxa were identified here for the first time during the Neolithic period, or represent the oldest mention of these parasites. This new paleoparasitological contribution reinforces our knowledge of intestinal parasites in Neolithic populations and provides new data on their history.
