La arqueología Experimental ha tenido una amplia difusión tanto en el ámbito investigador como en el divulgativo en las últimas décadas. No obstante, su empleo en la generación de modelos arqueológicos simulados ofrece un recurso de enorme potencialidad para poder profundizar en el campo de la interpretación del registro arqueológico. En este traba...

Shaped stone balls (SSBs) were an integral part of human culture across the Old World for nearly 2 million years. They are one of the oldest implements made and used by humans. In this significant era, which was characterised by biological and cultural transformations, these round implements were a stable hallmark throughout the Lower Paleolithic p...

The mobility of objects and the people behind them constitutes the most outstanding topic addressed by lithic sourc-ing in Palaeolithic Archaeology. The historiography generally highlights the discovery of the longest contact in a determined period or region, but also a broad historical construct consisting of a continuum evolutionary trend towards...

Lithic artefacts are usually associated with the different knapping methods used in their production. Flakes exhibit metric and technological features representative of the flaking method used to detach them. However, lithic production is a dynamic process in which discrete methods can be blurred, and in which features can vary throughout the proce...

Predicting original flake mass is a major goal of lithic analysis. Predicting original flake mass allows for researchers to make estimations of remaining mass, lost mass, and other features. All these measures relate to the organization of lithic technology by past societies. The present work tests three different models to predict log of flake mas...

The use of the indirect percussion technique in the production of bifacial elements during advanced stages ofthePrehistory has been taken into consideration in a very superficial way by prehistoric archaeologists and technologists. The widespread assumption of the use of soft direct percussion as the main technique involved in bifacial reductions h...

Polyhedrons, spheroids and bolas (PSBs) are present in lithic series from the Lower Palaeolithic onwards and are found in several regions of the world. Nevertheless, very little is known about them. We propose here to summarise, illustrate and discuss the current state of our knowledge about these artefacts. Based on the available data in the liter...

The consideration of quartzite as a secondary raw material has relegated in-depth research of this raw material in favour of such other rocks as flint or obsidian. The latter two are the most researched raw materials because of the information derived from their study: long-distance transport of rocks and mobility of people. In contrast, informatio...

Shaped stone balls are ubiquitous in Oldowan and Acheulian sites worldwide. Despite years of research, very little is known about the shaping process of these items. A comprehensive literary review indicates variability in the types of rocks from which these items were shaped. At a number of sites, however, selectivity in the choice of materials us...

The complete analysis of the materials including the last section of the sequence corresponding to the last chronological interval of the occupation in the region s...

Estimating flake mass based on remaining attributes bears an important relationship for the interpretation of lithic assemblages. Previous works have pointed out the relationship between flake attributes and prediction of flake mass. This study builds on previous works by using data from an experimental collection of flakes. Estimated mass was arri...

Raw material characterization in Paleolithic archaeology has widened our knowledge of Middle Paleolithic societies. Procurement of raw material, specifically flint, has allowed the tracing of the mobility of both stones and people, as well as selective processes to obtain specific types or even extraction activities. The analysis of quartzite has a...

More and more contributions to the field of lithics are taking into consideration skill levels and learning processes in prehistory, with the aim of clarifying not only how individuals acted when they produced their tools but also of addressing the processes of change or continuity in the technocultural traditions of past societies and the particip...

The presence of shaped stone balls at early Paleolithic sites has attracted scholarly attention since the pioneering work of the Leakeys in Olduvai, Tanzania. Despite the persistent presence of these items in the archaeological record over a period of two million years, their function is still debated. We present new results from Middle Pleistocene...

Either for food or as raw material, plants were probably the most important resource for past hunter-gatherer communities in the temperate regions of the planet. For this reason, if we want to know the economic and social organization of past societies, there is an urgent need to understand their relationship with plants. On the other hand, despite...

Many Paleolithic lithic collections are found in contexts where post-depositional alterations, such as those made by water streams or sedimentary displacement, have affected the surface of most of the lithic artifacts. A major alteration often observed is the rounding of lithic artifacts. Although there have been some proposals on how to classify d...

One of most recent Mousterian sites discovered in Madrid (Spain) is El Cañaveral-Area 3 archaeological site, an open-air raw material quarrying site occupied during the MIS 3. In this site, we have excavated a total surface area of around 164 m² of coluvionar sediments affected by edaphic processes that have had an impact on the distribution of the...

The consideration of quartzite by prehistorian as a secondary raw material has avoided in-depth research of this raw material as other rocks, such as flint or obsidian. The two latter ones are the better studied raw materials because of the information derived from its study: long-transport of rocks and mobility of people. In contrast, the informat...

The study of the lithic assemblage from Charco Hondo 2 (Madrid, Spain) indicates the existence of intense activities related to the quarrying of Miocene flint outcrops, within a drainage context inside the interfluvial plateau of the Manzanares and Jarama rivers (Madrid region). This lithic production was oriented to produce the first stages of lar...

Retouched artifacts are one of the most common elements of Middle Paleolithic lithic assemblages. Resharpening of the edges by retouch is integral to key concepts of lithic technology and patterns of site occupation dynamics. This has led to the development of indexes that quantify retouch among artifacts, allowing comparisons according to raw mate...

In this work, we present a regional study with which we intend to analyze the possible exploitation models that on different ecosystems, were used the human groups throughout the Upper Pleistocene in the Madrid region. This area is not only characterized by abundant resources of different nature and especially abiotic, but also by its varied ecolog...

The development of raw material characterisation in Palaeolithic Archaeology in the last fifty years has widened our knowledge about the societies who inhabited Europe in the past.

Abstract This work presents a synthesis on the stratigraphy and geochronology of the Quaternary Period after the chronological updating ratified by the International Commission on Stratigraphy (ICS-IUGS) and the International Union for Quaternary Research (INQUA). We show the more recent (updated) stratigraphic, chronologic and paleoclimatic data...

Ethnographic and archaeological evidences showed that hunter-gatherers adaptive capacity was expressed, among other things, by strategy of raw material selection and diversification. The variability of lithic raw materials used included resources such as limestone, quartz, schist, and other highly inhomogeneous and less isotropic stone resources. F...

Variability and efficiency of limestone knapping

Introduction and objectives: Although the Iberian Peninsula is a key area for understanding the Middle to Upper Paleolithic transition and the demise of the Neandertals, valuable evidence for these debates remains scarce and problematic in its interior regions. Sparse data supporting a late Neandertal persistence in the Iberian interior have been...

Characteristic pedunculated points have traditionally been assigned to the Upper Solutrean period. Evidence from the populations that inhabited thein El Higueral-Guardia Cave region indicate that this region was also occupied during this chronocultural period. In the first excavation season in August 2012 at El Higueral-Guardia Cave (Málaga, Spain)...

The recent excavations (2008–2009) conducted at the open-air site of Las Delicias, located in the Manzanares River valley (Madrid), have revealed new important data for the understanding of the human settlement of Central Iberia during Solutrean times. In this paper, we present a geomorphological and taphonomic study of the Pleistocene deposits of...

During Prehistory, shells have been used for subsistence, ornamentation, symbolic behaviour and tools. The investigation of shell tools has been mainly carried out from the viewpoint of functional analysis by investigating use-wear traces to reconstruct the functional value of these artefacts. Little attention has been devoted to investigating the...

The existence of a more or less complex handling technology with the lithic tools during the Lower and Middle Paleolithic is an interesting topic for understanding aspects of the human behavior during these periods. In this work we present a preliminary experimental evaluation of the possible functionality of prehensile area in some of the most rep...

La "enseñanza colegiada" (Finkel y Arney, 1995, p.199 y ss; Finkel, 2008, p.227-236) es un tipo particular de docencia en equipo que consiste en la presencia simultánea de al menos dos profesores en el aula, de los que se espera establezcan entre ellos debates ante los alumnos sobre diversas cuestiones relevantes para la asignatura.En este trabajo...

The Solutrean settlement of the Manzanares River valley (Madrid basin) has been a controversial topic over the history of the discipline. Despite the large number of bifacial assemblages, often considered Solutrean, known in the valley since the beginnings of the 20th century, their lack of stratigraphic references, chronometric dates and environme...

The presence of thermally altered and broken flint artifacts is common at archaeological sites. Most studies focus their attention on the effects of heat treatment on flint to improve knapping qualities, disregarding the effects of fire over flint under uncontrolled conditions. This paper aims to show how under uncontrolled heating processes flint...

The basins of the Manzanares and Jarama rivers have been connected to human activity since the early Palaeolithic. At the boundary between these rivers the abundance of flint has given place to exploitation and mining activities even in historical times. In recent years, projects related to urban expansion in the southeast of Madrid have brought to...

Neanderthal shell tools have been discovered in several coastal sites along the Mediterranean Sea in the past 50 years. These technological artefacts have rarely been investigated, and only typological considerations have been published. Recent studies have investigated retouched shell tools at Grotta del Cavallo with a new multidisciplinary method...
