Introduction
My lines of research are diverse, with special interest on the analysis of the Neolithisation, Megalithism and Bell Beaker phenomena. My individual research focuses on the analysis of the Megalithism from a biographical approach. This has been the subject of my PhD. Currently I am also interested on chronometric analysis through the Bayesian Statistics. Other important subject of my research is the cross-border issue, particularly between Spain and Portugal.

Archaeological research in the Dolmen of El Pendón (Reinoso, Burgos, Spain) has brought to light the complex biography of a megalithic monument used throughout the 4th millennium cal. BC. The ossuary of this burial holds the bones of nearly a hundred individuals who suffered from diverse pathologies and injuries. This study presents the discovery o...

Hepatitis B virus (HBV) has been infecting humans for millennia and remains a global health problem, but its past diversity and dispersal routes are largely unknown. We generated HBV genomic data from 137 Eurasians and Native Americans dated between ~10,500 and ~400 years ago. We date the most recent common ancestor of all HBV lineages to between ~...

En las asignaturas vinculadas al área de Prehistoria, los alumnos aprenden cómo vivían sociedades que no dejaron huella escrita, por lo que el estudio del patrimonio arqueológico es un pilar fundamental. A menudo, los estudiantes reciben una explicación sobre esta cultura material acompañada de recursos gráficos en 2D, como fotografías, vídeos o di...

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 (Bisaur...

Abstract: The archaeological research at Els Trocs cave is a good example of a successful transdisciplinary project. Together with a great team of specialists in different areas of knowledge, we present an update of our research process. The site is a cave that was occupied for more than two millennia, from the Early Neolithic (the end of the 6th m...
Research Proposal
Full-text available
This session wishes to address approaches and interpretations that determine understandings and values that may have been shared within the greater Megalithic tradition of Europe’s Atlantic coastline. Whilst the building of megalithic monuments, which includes stone tombs, standing stones and megalithic buildings, is a worldwide, time-transcending...

Abstract: (Survival of dual Hunter-Gatherer ancestry in the Iberian Peninsula): The Iberian Peninsula conformed a periglacial refugium for Pleistocene hunter-gatherers (HG) during the Last Glacial Maximum (LGM) which served as a potential source for the re-peopling of northern latitudes. After 14,000 years ago, the genetic signature was dominated b...

"¿Qué es lo imprescindible para que un lugar exista?" ¿Permanece o se transforma? ¿Se convierte en otro lugar al transformarse? ¿Los elementos que lo caracterizan tienen duraciones diferentes? ¿Qué ocurre cuando deja de existir? De un modo u otro, como arqueólog@s, tod@s nos enfrentamos reflexivamente a estos procesos de comprensión sobre el cambio...
Article
Full-text available
Violence seems deeply rooted in human nature and an endemic potential for such is today frequently associated with differing ethnic, religious or socio-economic backgrounds. Ethnic nepotism is believed to be one of the main causes of inter-group violence in multi-ethnic societies. At the site of Els Trocs in the Spanish Pyrenees, rivalling groups o...

The knowledge of climatic and environmental changes at the onset of the Holocene and its impact on human populations and cultures is key for the understanding of their both past and future evolution. In this sense, the study through trenching and cores of the Holocene archaeosedimentary record in the surroundings of the Los Cascajos Neolithic archa...
Article
The Iberian Peninsula in southwestern Europe represents an important test case for the study of human population movements during prehistoric periods. During the Last Glacial Maximum (LGM), the peninsula formed a periglacial refugium [1] for hunter-gatherers (HGs) and thus served as a potential source for the re-peopling of northern latitudes [2]....

RESUMEN La utilización de la estadística bayesiana en el análisis de las dataciones radiocarbónicas, no es una novedad en los estudios de la Prehistoria Reciente del Sureste ni tampoco en la costa mediterránea peninsular. Sin embargo es un método que hasta la fecha no se ha aplicado a la periodización de la Edad del Hierro en el valle del Ebro. En...

Megalithism is one of the most outstanding evidence from prehistoric societies at the turn of the Metal Ages. Since the 4th millennium, megaliths were constructed to be used as funerary and ceremonial structures across the European geography. Within the boundaries of Duero Valley human groups built different types of megalithic structures used alon...

Agriculture frst reached the Iberian Peninsula around 5700 BCE. However, little is known about the genetic structure and changes of prehistoric populations in diferent geographic areas of Iberia. In our study, we focus on the maternal genetic makeup of the Neolithic (~ 5500–3000 BCE), Chalcolithic (~ 3000–2200 BCE) and Early Bronze Age (~ 2200–1500...

During the 1980 s, acoustic studies of Upper Palaeolithic imagery in French caves—using the technology then available—suggested a relationship between acoustic response and the location of visual motifs. This paper presents an investigation, using modern acoustic measurement techniques, into such relationships within the caves of La Garma, Las Chim...

The passage grave of El Teriñuelo is located in the village of Aldeavieja de Tormes (province of Salamanca). It is part of one of the most important and well-documented megalithic areas of inner Iberian Peninsula. Since before 1930 several archaeological works have taken place at this passage grave, thanks to which it has been possible to reconstru...

The beginnings and development of the Neolithic in North-West Africa is a subject about which little information is available. The archaeological work undertaken in Morocco during the French and Spanish colonial periods was followed by a time of ostracism and neglect until the 1970s, when the team of Professor P. Daugas re-initiated research on the...

Photogrammetry is the technique which allows to convert 2D images to 3D models to obtain the object´s geometric characteristics. To achieve that, the most important step is the capture of the photographs that will serve as a base for the next processing made by a photogrammetric software. The final result is a 3D model with a photorealistic texture...

The Megalithism in the Duero Basin shows a wide range of different monuments, both the more orthodox types (simple dolmens and passage graves) and others lacking the orthostatic structures (simple mounds, “lime-kiln” tombs). In this article two recent discoveries are presented that were found and excavated in the Burgos and Soria provinces. Differe...
