Procesos técnicos y culturales durante el Holoceno inicial en el noroeste de la Península Ibérica. Los niveles B y Bb de La Cativera (El Catllar, Tarragona)

This study presents the technological structure observed in levels B and Bb (Boreal) from La Cativera. A dual technological pattern is observed. For one side simplified blade exploitation is observed and for the other, a normalized short flake production is documented too. A new 14C data corroborates the chronological position of both levels despite showing technical schemes which significantly vary from those of synchronous sites. The B and Bb levels match in time with the so called Notched and Denticulate Mesolithic industries, however the observed knapping patterns present a major affinity with the Late Magdalenian or Epipalaeolithic Late Glacial knapping schemes.Este trabajo presenta la estructura tecnológica observada en los niveles B y Bb (Boreal) de La Cativera, donde se observa una dualidad entre explotaciones laminares simplificadas y una producción de lascas cortas normalizadas. Una nueva datación inédita refuerza la posición cronológica de estos niveles pese a que las estrategias de talla de los mismos difieren significativamente de las documentadas en yacimientos sincrónicos. Los niveles B y Bb coinciden en el tiempo con los conjuntos del Mesolítico de Muescas y Denticulados, sin embargo el análisis tecnológico de la industria lítica lo pone en relación más directa con los conjuntos del Magdaleniense final y/o Epipaleolítico microlaminar propios del Tardiglaciar

El Mirador cave (Sierra de Atapuerca, Burgos, Spain): a whole perspective

The archaeological site of El Mirador is located in the southern slope of the Sierra de Atapuerca. The work developed at the site is providing a substantial set of data from the Upper Palaeolithic and Early Neolithic to the Middle Bronze Age. Throughout at least about 4000 years of occupation, the cave was used for various activities, among which, burial, habitation and animal stalling. The practices related with this last use is, at the moment, the main origin of the archaeological deposits, which are mainly composed by burnt animal dung with vegetal residues, potsherds, lithics and faunal remains. In addition, it is characterized by high sedimentation rates that have enabled an individual and clear record of different episodes, providing high resolution chronological data. Due to these particularities, specific excavation methodology and interdisciplinary studies of the archaeological data have been developed in order to understand the genesis of this archaeological sequence and, at the same time, to provide information about the introduction and development of the production economy in the Submeseta Norte region.The Ministerio de Ciencia e Innovación (N_CGL2009-12703-C03-02/BTE; HAR200801984/HIST) and the Ministerio de Economía y Competitividad (CGL2012-38434-C0303; HAR2013-41197-P) and the Generalitat de Catalunya (2014SGR900; 2014SGR899) supported this research. Funding for the fieldwork came from the Consejería de Cultura y Turismo of the Junta de Castilla y León and the Atapuerca Foundation. Á. Carrancho research was funded by the Spanish Ministry of Economy and Competitiveness (MINECO) and European Regional Development Fund (FEDER) with projects CGL2012-32149 and CGL2012-3848

The first hominin of Europe

The earliest hominin occupation of Europe is one of the most debated topics in palaeoanthropology. However, the purportedly oldest of the Early Pleistocene sites in Eurasia lack precise age control and contain stone tools rather than human fossil remains(1-5). Here we report the discovery of a human mandible associated with an assemblage of Mode 1 lithic tools and faunal remains bearing traces of hominin processing, in stratigraphic level TE9 at the site of the Sima del Elefante, Atapuerca, Spain(6-8). Level TE9 has been dated to the Early Pleistocene ( approximately 1.2 - 1.1 Myr), based on a combination of palaeomagnetism, cosmogenic nuclides and biostratigraphy. The Sima del Elefante site thus emerges as the oldest, most accurately dated record of human occupation in Europe, to our knowledge. The study of the human mandible suggests that the first settlement of Western Europe could be related to an early demographic expansion out of Africa. The new evidence, with previous findings in other Atapuerca sites ( level TD6 from Gran Dolina(9-13)), also suggests that a speciation event occurred in this extreme area of the Eurasian continent during the Early Pleistocene, initiating the hominin lineage represented by the TE9 and TD6 hominins.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/62855/1/nature06815.pd
