12000 years of human occupation, 3 meters deep stratigraphy, 12 hectares⊠A geographical information system (GIS) for the preventive archaeology operation at Alizay (Normandie, France)
International audienceAn archaeological investigation carried out by INRAP (Institut national de recherches archéologiques préventives) revealed that banks of the river Seine at Alizay (Normandy, France) were occupied during 12000 years. The specifications of the excavation were to study various occupations (Upper Palaeolithic, Neolithic, Iron Age and Middle Age) applying the appropriate methodology for each major period. A Leica TS15 robotic total station was used to rapidly record archaeological features and store directly in the field pre-formatted GIS data. The aim of the process was to inventory and study, during the excavation, the 120 000 exhumed artefacts using a Microsoft Access database linked to a geodatabase in Esri ArcGIS. This specific archaeological information system was designed to guide the earth removal, by producing digital elevation model of each stratigraphic context, facilitate the management and inventory of artifacts and spatialize the data produced during the excavation
Habitat de la fin du IXe-début Xe siÚcle (Bretagne, Ille-et-Vilaine, Martigné-Ferchaud, La Grande Ragée): Rapport de fouille archéologique 2016
National audienceLe site mĂ©diĂ©val de La Grande RagĂ©e Ă MartignĂ©-Ferchaud (Ille-et-Vilaine) a fait lâobjet dâune fouille archĂ©ologique au printemps 2014 sur le tracĂ© de la future deux fois deux voies Rennes-Angers, aprĂšs quâun diagnostic en a rĂ©vĂ©lĂ© des indices (Barbeau, 2013). Sur une surface de prĂšs de 1,2 ha, nous avons pu mettre au jour les tĂ©moins dâune occupation rurale « calĂ©e » autour de la fin du IXe siĂšcle pour une dĂ©sertion probable dans les premiers temps du Xe siĂšcle. De part et dâautre dâun chemin, sur les premiĂšres dĂ©clivitĂ©s dâune petite colline peu marquĂ©e, et dans les limites restrictives dâune opĂ©ration prĂ©ventive, nous observons une juxtaposition dâunitĂ©s agricoles. Cinq ensembles lotis et exploitĂ©s peuvent ĂȘtre reconnus se dĂ©veloppant selon une organisation relativement claire : deux bĂątiments sur ancrage de poteaux composent le corps principal de ces unitĂ©s. Hors de la zone dâhabitat, lâoccupation plus lĂąche signale lâamorce dâespaces agraires
Torcé, Vassé (Bretagne, Ille-et-Vilaine) : Habitat enclos fin VII<sup>e</sup>-IX<sup>e</sup> siÚcle: Rapport de fouille 2014
International audienceLe site dâhabitat du premier Moyen Ăge de « VassĂ© » Ă TorcĂ© (Ille-et-Vilaine), sur le tracĂ© de la LGV Rennes-Le Mans, a fait lâobjet dâune fouille archĂ©ologique en 2012 sur une surface de 1,4 hectares, suite Ă un diagnostic archĂ©ologique. Ce dernier a dâailleurs permis de rĂ©vĂ©ler un second site au lieu-dit « âLa Grande Maçonnais » (800 m plus Ă lâouest) mis aussi en ligne dans cette collection. Ces deux opĂ©rations de fouilles archĂ©ologiques se placent au sud-est et au sud du bourg de TorcĂ©, Ă moins dâun kilomĂštre de son Ă©glise. Cette derniĂšre, avec sa crypte et son sarcophage en plomb non datĂ©s, comporte des Ă©lĂ©ments architecturaux du XIe siĂšcle. Sa dĂ©dicace Ă Saint MĂ©dard (Ă©vĂȘque du VIe siĂšcle) pourrait ĂȘtre un indice de plus grande anciennetĂ©. Juste Ă cĂŽtĂ©, la dĂ©couverte de sarcophages en calcaire coquillier, lors du nivellement de la motte castrale au XIXe siĂšcle, ajoute un indice supplĂ©mentaire. Ce mode dâinhumation, le plus prestigieux pour la pĂ©riode et la rĂ©gion, est en usage du VIe aux Xe-XIe siĂšcles..

Earthern architectures and Megalithism: the Soto monument (Senegal)
International audienceSince 2015, archaeological research carried outon the site of Soto (Kaffrine region, Senegal -L. Laporte and H. Bocoum, dir.) shed new light at funerary tumulistructures (Mbaanar) so far little studied. Among all acceptionsthe term Mbaanarcovers, many of them are materializedin the landscape by discretemounds of less than fifty centimetersin height. Very few exampleshave a frontal stone erected ontheireastside, as it is the case in Soto. On the eastern periphery of the tumulus, a protohistoric ground level is indicated by a crown of laterite gravel. A broad depression in its center indicates the initial location of the lyre stone. Extracted in 1964, this stone with central tenon is now exposed and integrated into the collections of the Musée du Quai Branly (Paris, France). Geophysical sur-veys conducted at Soto had highlighted a «clay anomaly» in the centerof the monument. This one is surrounded by a discontinuous peripheral ditch and some hollow structures. Extensive excavationsthen made it possible to revealthe entirety of a monumental earthen architecture of about 25 m in diameter and at least 1.5 m high. This oval-shaped monument iserected at thecenter of a large circular pit and issurrounded by several more or less continuous peripheral ditches. The structure of the monument testifies to an ela-borate architectural project and a mastery of mud construction techniques. A geoarchaeological study is actually in progress, in parti-cular to specify construction techniques and identify possible collapsed parts of the earthen architecture. His central part is made of a yellow earth core, probably surrounded by a palisade of about 10m in diameter whichmay have initiallycovered the funerarylevels. Then, several beds of raw earth placed at the top coverthe entire structure, appearing as many successive steps. On one of them, a spearhead had been planted vertically. For the first time in West Africa, this multidisciplinary work reveals a completely unsuspected monument in size and shapewhere many had previously seen only small sand hills. This somehow well-hidden ostentation is here associated with a more classic megalithic element, now exposed to the sight of millions of visitors
