This work presents new contributions to the understanding of the biological and cultural aspects of the population that erected and used the Megalithic Tomb of Santa Rita, located in the municipality of Vila Real de Santo António, Portugal. The bones studied in this research came from the funerary chamber, which was used as a secondary and collective funerary space during the Chalcolithic, between the end of th...
In this study, total mercury (THg) was analyzed in archaeological human bone from 23 sites dating to between the Middle Neolithic and the Antiquity. A total of 370 individuals from individual or collective burials was sampled, mostly using cortical bone from the humerus. These individuals were recovered from over 50 different funerary structures ranging from tholoi, pits, caves, and hypogea. Although cinnabar (...
The Guadalquivir River Valley constitutes the main geographic environment for the earliest development of political structures in the South of the Iberian Peninsula. The inception of Cu-metallurgy over the millennia 4th to 2nd BC in this region coincides with the rise of social complexity as well as the strategic control of the territory based on the command of the supply of mineral resources. One of the main t...

The Neolithic site of Casas Novas (Coruche, Portugal) has provided the earliest evidence of Neolithic occupation currently known on the left bank of the Tagus River. The material culture and the radiocarbon date show an occupation that fits in the earliest moments of the regional Neolithic. The typological and decorative characteristics of the ceramic assemblage show contacts and influences both from Mediterran...
El asentamiento de Valencina de la Concepción (Sevilla, España) es un referente en la arqueología prehistórica peninsular, no solo por sus grandes tumbas, sino también por su gran magnitud. En los últimos años, la investigación ha centrado su atención en el estudio de la organización técnica y social de las primeras producciones artesanales, con especial hincapié en la metalurgia y en la manufactura de objetos ...
Background and Purpose—Some patients with ischemic strokes that are currently classified as having an undetermined cause may have structural or functional changes of the left atrium (LA) and left atrial appendage, which increase their risk of thromboembolism. We compared the LA and left atrial appendage of patients with different ischemic stroke causes using cardiac magnetic resonance imaging. Methods—We prospe...
El asentamiento de Valencina de la Concepción (Sevilla, España) es un referente en la arqueología prehistórica peninsular, no sólo por sus grandes tumbas, sino también por su gran magnitud. A pesar de las innumerables evidencias sólo recientemente la componente cerámica ha sido objeto de un amplio estudio que ha permitido proponer un primer modelo de organización técnica y social de la producción alfarera. Por ...
Este trabalho pretende abrir uma nova linha de investigação através do estudo das opções técnicas exercidas durante a manufactura de cerâmicas documentadas em contextos megalíticos. O estudo petrográfico de oito amostras de cerâmica provenientes de diferentes contextos do túmulo megalítico de Santa Rita revelou a utilização de argilas locais. Porém, é possível que a utilização destas matérias-primas não estives...
The archaeological survey developed in prehistoric settlement of Valencina de la Concepción allowed us to recognize an important archeological context where stands a large concentration of beaker pottery. The archaeometric study of common and beaker pottery and its comparation with the regional geology and sediments previously collected has identified the possible areas of clay raw material supply.; Las excavac...
