The last Acheulean at El Sotillo complex site (Ciudad Real, Spain). Features, parallels and age
The site of El Sotillo has several distinct stratigraphic levels containing Acheulean and Mousterian lithic tools, dated to the final third of the Middle Pleistocene and the later phases of the Upper Pleistocene. It is uncommon to find open-air sites, that preserve such intensive and recurrent human occupations in stratigraphic position over an extended time range, which underscores the complex nature of the site. Excavations carried out between …
Towards a formation model of the Neanderthal symbolic accumulation of herbivore crania
Understanding formation processes is crucial for interpreting sites with complex sedimentary histories and exceptional archaeological records, such as Level 3 of Des-Cubierta Cave. This Middle Paleolithic unit contains an assemblage of anthropically modified ungulate horned crania, Mousterian lithics, and evidence of fire use, all preserved in a clast-supported gravel deposit shaped by successive rockfalls. This study integrates geostatistical an…
European Large Flake Acheulean on Flint
The Acheulean of the Iberian Peninsula and southern France share some of the technological characteristics that define the African Acheulean, such as the configuration of handaxes, cleavers and picks, mainly using flakes as supports. The existence of large flake Acheulean lithic assemblages in the middle terraces of all the fluvial valleys of the Atlantic watershed of the Iberian Peninsula allows dating the early expansion of this technocomplex c…
Reconstructing Skills and Strategies of Hominins During the Early Acheulean
Technological strategies for biface manufacture adopted during the Acheulean represent a significant shift in the Lower Palaeolithic. The appearance of intentional bifacial shaping indicates the imposition of form on stone tools not seen previously. Despite this importance, there is considerable scope for research into hominin decision-making while factoring in the differential properties of varied raw materials. Here, we discuss the results of a…
Experimental use-wear on non-flint tools
Mixed sites
Understanding taphonomic processes is essential for reconstructing past environmental dynamics and interpreting mixed sites, where successive occupations by different biological agents have occurred and, in many cases, have been modified by post-depositional processes. Such is the case in the western part of Buena Pinta Cave (Pinilla del Valle, Madrid). In this study, three Units with different taphonomic histories were analysed. Unit 32 A contai…
Intra-site spatial approaches based on taphonomic analyses to characterize assemblage formation at Pleistocene sites
Buena Pinta Cave (Pinilla del Valle, Madrid) has been interpreted as a hyena den with sporadic occupations of Homo neanderthalensis in the western part of the site (level 23). In order to identify the different formation processes in this area of the site, spatial analyses have been carried out with GIS and spatial statistics based on the taphonomic analysis of the faunal remains. Based on the vertical and sectional analyses of the assemblage, it…
Aproximación tafonómica al Abrigo de Navalmaíllo
Los retocadores óseos son considerados como parte de la industria ósea de los grupos humanos pleistocenos. Normalmente se caracterizan por ser fragmentos de diáfisis de ungulados empleados para retocar el filo de una herramienta lítica. Estos objetos son relativamente abundantes en contextos del Paleolítico Medio, aunque hay una amplia variabilidad según los diferentes yacimientos. En este trabajo presentamos dos nuevas evidencias de retocadores …

Spatial analysis of an Early Middle Palaeolithic kill/butchering site
Kill/butchering sites are some of the most important places for understanding the subsistence strategies of hunter-gatherer groups. However, these sites are not common in the archaeological record, and they have not been sufficiently analysed in order to know all their possible variability for ancient periods of the human evolution. In the present study, we have carried out the spatial analysis of the Early Middle Palaeolithic (MIS 9-8) site of C…
Identifying activity areas in a neanderthal hunting camp (the Navalmaíllo Rock Shelter, Spain) via spatial analysis
Spatial analysis has been much used to examine the distribution of archaeological remains at Pleistocene sites. However, little is known about the distribution patterns at sites identified as hunting camps, i.e., places occupied over multiple short periods for the capture of animals later transported to a base camp. The present work examines a Neanderthal hunting camp (the Navalmaíllo Rock Shelter in Pinilla del Valle, Madrid, Spain) to determine…
A symbolic Neanderthal accumulation of large herbivore crania
This work examines the possible behaviour of Neanderthal groups at the Cueva Des-Cubierta (central Spain) via the analysis of the latter's archaeological assemblage. Alongside evidence of Mousterian lithic industry, Level 3 of the cave infill was found to contain an assemblage of mammalian bone remains dominated by the crania of large ungulates, some associated with small hearths. The scarcity of post-cranial elements, teeth, mandibles and maxill…

The evolution of stone tool technology at Olduvai Gorge (Tanzania)
Exploring the formation processes on open-air palaeolithic sites
The analysis of formation processes (e.g., degree of surface alterations, size ranges, orientation patterns, fabric features, density, spatial patterns, etc.) in archaeological sites provide relevant information about the type and intensity of sedimentary disturbances. This type of analysis is particularly important in Palaeolithic sites, especially when the stratigraphic context suggests certain sedimentary disturbances. This study follows a mul…
El Parque Tecnológico del Valle de los Neandertales (el Calvero de la Higuera, Pinilla del Valle, Comunidad de Madrid)
Los yacimientos del Calvero de la Higuera (Pinilla del Valle, Madrid) son un referente para comprender la forma de vida, relación con el medio y capacidad simbólica de los grupos de neandertales que habitaron este territorio durante el Pleistoceno Superior. Los trabajos arqueológicos que, sobre todo desde 2002, se desarrollan en dicho enclave, situado en la región montañosa del Valle Alto del Río Lozoya en la Sierra madrileña, han permitido recon…
Revisión del componente achelense de la industria lítica de Galería (Atapuerca, Burgos, España)
La industria lítica del yacimiento de Galería (complejo de Atapuerca, Burgos), datado en la segunda mitad del Pleistoceno Medio, ha sido interpretada como uno de los más notables conjuntos del tecnocomplejo achelense que se conocen en la península ibérica y en el sur de Europa. Se ha estimado que su prolongada secuencia estratigráfica permitiría observar la evolución del Achelense en la segunda mitad del Pleistoceno Medio. Esta propuesta ha sido …

Petrographic and SEM‐EDX characterization of Mousterian white/beige chert tools from the Navalmaíllo rock shelter (Madrid, Spain)
Studying lithic raw material sourcing, processing and distribution is helpful when trying to reconstruct the territory, ecology, and cultural practices of Neanderthal groups. The use of multiple methods in such analyses allows for more refined characterizations to be made, helping to distinguish between materials better than any single method. Although 85% of the raw materials making up the Mousterian assemblage at the Navalmaíllo Rock Shelter (P…

The Magnetic Stratigraphy of the Late Miocene Sediments of the Cabriel Basin, Spain
Paleomagnetic Age for Hominid Fossils at Atapuerca Archaeological Site, Spain
A paleomagnetic investigation at the Gran Dolina site excavation (Atapuerca, Spain) shows that the sediments containing the recently discovered human occupation were deposited more than 780,000 years ago, near the time of the Matuyama-Brunhes boundary. Forty-one oriented samples were obtained from 22 sites along an 18-meter section of the Gran Dolina karst filling. The lower 16 sites displayed reversed-polarity magnetizations whereas the upper si…
Paleoenvironmental Changes during the Last 4000 yr in the Tigray, Northern Ethiopia
In the Tigray region at the northern Ethiopian Highlands, paleoenvironmental reconstruction based on several infilled valley deposit sequences suggests that the past 4000 yr comprised three major wetter periods (ca. 4000–3500 yr B.P., 2500–1500 yr B.P., and 1000–960 yr B.P.), during which soils were formed, and two degradation episodes (ca. 3500–2500 yr B.P. and 1500–1000 yr B.P.), during which there was an increase of sediment yield from the slo…

El yacimiento de la estación de las Delicias (Madrid). La investigación del Paleolítico en el Manzanares
The archaeological site of Las Delicias (Madrid) excavated by Obermaier and Wernert in 1918, it has been one of the most important classic palaeolithic sites of the Manzanares valley for years. In this paper we offer a critical review of all the data caming from ancient excavation, together with an historiographical evaluation of the different interpretations based on lithic industry of the site, and finally we want to set some objectives looking…
On the age of the hominid fossils at the Sima de los Huesos, Sierra de Atapuerca, Spain
We report new paleomagnetic data for the Middle Pleistocene hominid-bearing strata in the Sima de los Huesos, North Spain. Sediments (brown muds with human and bear fossils and the underlying sterile clayey and sandy unit) preserve both normal and reversed magnetic components. The sterile unit has exclusively reversed magnetization, dating back to the Matuyama Chron, and thus is Lower Pleistocene in age. The overlying fossiliferous muds have a do…

Characterizing the Sedimentary History of Cave Deposits, Using Archaeomagnetism and Rock Magnetism, Atapuerca (Northern Spain)
We use a combination of rock magnetism (anisotropy of magnetic susceptibility, AMS) and magnetic polarity to characterize cave deposits and as a proxy for sedimentary fabric. In three localities at the Atapuerca archaeological site (Galeria, Gran Dolina and Sala de los Cíclopes), magnetic foliation (K max /K int ) is always greater than lineation (K int /K min ), consistent with a primary, depositional, sedimentary fabric. Our results, although p…
Hydrological response of a dryland ephemeral river to southern African climatic variability during the last millennium
A long-term flood record from the Buffels River, the largest ephemeral river of NW South Africa (9250 km 2 ), was reconstructed based on interpretation of palaeoflood, documentary and instrumental rainfall data. Palaeoflood data were obtained at three study reaches, with preserved sedimentary evidence indicating at least 25 large floods during the last 700 yr. Geochronological control for the palaeoflood record was provided by radiocarbon and opt…
Hundidero
Many caves in Sierra de Atapuerca contain archaeological and anthropological remains from the Early Pleistocene until the Holocene. The fi rst half of the Late Pleistocene (MIS 4 and 3) has only been detected in open air deposits discovered on the basis of total cover surface surveys. Excavation at one of them, Hundidero, began in 2004. The Middle Paleolithic tool record spans the period between 70 ka and 56 ka. The technological and typological …
