- Technology, use-wear and raw material sourcing analysis of a c. 7500 cal BP lithic assemblage from Cabeco da Amoreira shellmidden (Muge, Portugal)Publication . Paixão, Eduardo; Marreiros, Joao; Pereira, Telmo; Gibaja Bao, Juan; Cascalheira, João; Bicho, NunoThe onset of the Holocene is marked by new human ecological adaptations that are associated with the origins of the Mesolithic in the Atlantic Iberia coast. During the Mesolithic, shellmidden deposits become one of the most relevant and interesting prehistoric archeological contexts, interpreted has the result of intensive human ecological exploitation, and marked by new settlement and mobility patterns, and subsistence strategies. Based on techno-typological patterns and artifact density, each Muge shellmidden has been traditionally linked to a single and specific functionality, possibly reflecting the presence of different stylistic/ethnic groups in the territory. Therefore, characterizing settlement, mobility, site function, and technological patterns in each shellmidden is fundamental to understand the archeological record and answer major questions related to human ecological behavior during the onset of the new Holocene climatic setting. This paper presents new data on the Mesolithic from the Tagus valley, using the case study of the lithic assemblage from layer 2 of Cabeco da Amoreira shellmidden. From our interpretation, by combining lithic raw material characterization and sourcing, techno-typological and use-wear analysis, this study aims to represent an important step on understanding resource exploitation, technological systems and site function, in order to address intra and inter-site variability. In what concerns lithic raw materials, they can be found in the Pleistocene gravels that compose the upper section of the Cenozoic deposits of the River Tagus, including those underneath the site. Nevertheless, the geochemical results suggest that the chert used has correspondence with local, regional, and exogenous areas. In sum, by characterizing the Cabeco da Amoreira shellmidden lithic assemblage, results and data aim to contribute to the discussion and new interpretations on shellmiddens' function and settlement occupation patterns during the Mesolithic.
- The necropolis of Can Gambus-1 (Sabadell, Barcelona). New data on the funerary practices during the Middle Neolithic in the northeast of the Iberian PeninsulaPublication . Roig, Jordi; Manel Coll, Joan; Gibaja Bao, Juan; Chambon, Philippe; Villar, Vangelis; Ruiz, Jordi; Terradas, Xavier; Eulalia Subira, MariaIn this paper we deal with the Neolithic burials at the site of Can Gambus-1, belonging of the so called Cultura de los Sepulcros de Fosa" (from end of the fifth to the beginning of the fourth millennia cal BC). The main aim is to present new data on the procedures of excavation of the pits, the materials used in the covering of the graves and the treatment given to some of the corpses. The detailed archaeological reconstruction of the funerary behaviour has been possible thanks to the exceptional state of preservation of the graves, the rigorous process of archaeological excavation, the anthropological study carried out, as well as to the achievement of a detailed taxonomic study of all the available evidences. Likewise, the grave goods recovered in the burials are presented. Their quantity and quality is outstanding compared with other similar funerary contexts. Probably this fact is due to the exclusive presence of adult individuals among the buried ones.
