Article
The continental Late Miocene is relatively well represented in North Africa, but stratigraphic gaps are present in the Vallesian due to the scarcity of localities from this time. In this paper, we present the small mammal association from the section of Guefaït 1, in the Aïn Beni Mathar Basin (Jerada, eastern Morocco). This sequence contains three...
Chapter
This chapter presents the first collective synthesis of Late Middle Palaeolithic lithic technology (MIS 4–3, ≈ 70-40 ka) from the Altai mountains to the Atlantic coast of Western Europe and the Mediterranean regions of Europe and the Levant. As early as the first half of the twentieth century, archaeological debates focused on characterising and in...

The Abric Romaní rock-shelter (Capellades, Barcelona) is a key site for studying the use of fire among Neanderthal communities. The evidence of its use, including the identification of heated faunal remains, has led to infer the practice of some domestic activities in the site, such as cooking, use of bones as fuel, or habitat surface cleaning thro...

Article
Most biogeographers considered the Maghreb to be part of the Palearctic biogeographic region, though it is relatively recently that the proportion of Palearctic species increased there. How and when exactly these biogeographic changes occurred is not well understood, but they are probably the result of the increasing aridification of the Sahara and...

This paper presents the limestone reduction sequences documented in levels M and Ob at Abric Romaní from a technological point of view. At level M, a recurrent knapping system has been identified, resulting in the frequency of pseudo-Levallois blanks. At archaeolevel Ob, the presence of Levallois methods are observed in association with this knappi...
Article
We describe small-sized specimens of the metailurine felid Dinofelis from a new Plio-Pleistocene site in North Africa. Dinofelis is a genus of saber-toothed cats mainly recorded from East and South Africa with numerous leopard to jaguar-sized species. The described specimens, clearly smaller than all the other African Dinofelis, resemble isolated r...

The High Plateaus Basin is an important region to understand landscape evolution and human occupation in North Africa during the Quaternary. We focused on the Gara Soultana area, applying Unmanned Aerial Vehicles, photogrammetry and a submeter Global Navigation Satellite System, for large scale geomorphological mapping. This work in the upper Moulo...
Article
Neanderthals are widely known to be a resilient human species that successfully faced constant and strong environmental fluctuations modifying the landscapes they inhabited and the availability of their potential resources. It has been traditionally assumed that environmental features could strongly affect human behaviour due to the stretch relatio...

Article
This study represents the first integrated approach to the lithic raw materials exploited by the Neanderthals that occupied the Abric Romaní site (NE Iberia). Focusing on chert as the most abundant raw material (>80% of the assemblages), we determine the potential procurement areas and the mobility patterns. Geo-archaeological surveys within a radi...
Article
Currently, approximately 90% of the human population is right-handed. This handedness is due to the later-alization of the cerebral hemispheres and is controlled by brain areas involved in complex motor tasks such as making stone tools or in language. In addition to describing the evolution of laterality in humans, identifying hand preference in fo...

Full-text available
In the last decades, we have witnessed crucial advances to describe and explain the variability of Mousterian lithic productions across Europe. This variability has important implications in terms of adaptive responses at the environmental and cultural changes that Neanderthals faced between ca. 300-30 kyr BP. The production of small tools is part...
Article
Full-text available
The phenomenon of microlithism continues to be one of the most interesting topics in the prehistoric archaeology of the Middle Palaeolithic period because it is key to understanding the technology and cultural and economic organisation of Neanderthal societies. The aim of this research is to characterise small-flake industries based on two archaeol...
Article
Recurrent long-and short-term Neanderthal occupations occurred in the Abric Romaní rock shelter (Capellades, Barcelona, Spain) for more than 20,000 years. This provides an opportunity to enhance our understanding of the evolution of behavioral strategies of these human groups. The site has a long and high-resolution sequence with 17 levels complete...
Article
Isolating the various occupational events in the Palaeolithic record is hard work, because the remains from different occupations commonly overlap, creating archaeological palimpsests. We can differentiate two different types of palimpsest: vertical and horizontal ones. These two types are very important for identifying and defining short-or long-t...
Article
Hunter-gatherers have a nomadic lifestyle and move frequently on the landscape based on the seasonal distribution of resources. During these displacements, carrying capacities are limited, and the composition of the transported gear is generally planned ahead of the activity to perform. During the Pleistocene, prehistoric hunter-gatherers faced sim...

A use-wear analysis was carried out on a specific mobile toolkit belonging to level M of the Middle Paleolithic site of Abric Romaní (Barcelona, Spain), which is dated to MIS 3, between 51 and 55 Ka BP. In an environment rich in local and regional chert sources and in a technological context marked by expedient behavior, a set of flakes, which also...
Chapter
Short-term human occupations could occur in very distinct places and be related to very different behaviours. The low number of items left by the human groups in these sites, usually, generates discrete assemblages, which often are difficult to disentangle. In the European Middle Palaeolithic, short-term human occupations in caves and rock-shelters...
Chapter
After deconstructing the palimpsest of level O, we present a cross-disciplinary study on a short occupation of the Abric Romaní rock shelter conducted by means of an analysis of the record of archaeo-level Oa, a Middle Palaeolithic assemblage dated to ca. 54 Ka BP by U/Th series. In this study, we present the steps we took to puzzle out the palimps...
Article
Mobility strategies of Neanderthal groups are studied through the characterization and analysis of archaeological sites and traditionally compared to the types of settlements present-day hunter-gatherer groups, based on their mobility strategies. The faunal record of level P of Abric Romaní is a unique source of information for analysing the foragi...

Full-text available
In several Middle Paleolithic assemblages in Western Europe, cores and bifaces with percussion zones that are not related to their usual mode of functioning have been observed. We used experimental cores and bifaces as percussion tools on different materials. The stigmata produced during percussion on stone materials closely resemble those observed...

The intrasite mobility of lithic artifacts is one of the most relevant issues that can be approached from the spatial study of refitting. In many sites, researchers have determined that some artifacts were abandoned at a considerable distance from the place where they were produced. Once natural causes of a post-depositional nature are ruled out, t...
Article
This study addresses the pollen record of Abric Romaní archaeological site and the climate evolution of the last interglacial and glacial stadials in the Iberian Peninsula. The new pollen record spans the interval from 110,000 to 55,000 years ago. In general, the glacial/stadial vegetation is characterized by a steppe and herbaceous communities ind...
Article
Full-text available
Monospecific exploitation of reindeer by Neanderthals is a common behaviour in the Upper Pleistocene of Western Europe. However, reindeer-dominated assemblages have largely been reported from regions of northern Germany and south-western France, with few examples noted in south-eastern France, where faunal assemblages yield most of the time a varie...
Conference Paper
The intra-site spatial patterns of lithic artefacts and their density are traditionally used in Prehistory as proxies for activity areas and social organisation of past human groups. This approach allows identifying domestic units, inferring number of co-resident, understanding site function and duration of occupation. These topics are especially i...

Isolate different occupational events in the Palaeolithic record is a hard work, because the overlapping of the remains from different occupations is very common, and this phenomenon creates archaeological palimpsests. We can differentiate two types of palimpsest: the vertical and the horizontal ones. These two types are very important to identify...

A micro and macro-wear analysis was carried out in a specific mobile toolkit belonging to level M of the Middle Palaeolithic site of Abric Romaní (Barcelona, Spain), which is dated at MIS 3, between 51 { 55 Ka BP. In an environment rich in local flint sources and in a technological context marked by an expedient behavior, a set of natural backed kn...
Article
The Abric Romaní site (Capellades, Barcelona, Spain) constitutes a key site for understanding the latest Neanderthal occupations in Western Europe. Here we present a comprehensive systematic and taphonomic analysis of a small-mammal assemblage from Level O of the Abric Romaní site, with the aim of reconstructing the paleoecological context in which...
Article
Full-text available
Over 60 years ago, stone tools and remains of megafauna were discovered on the Southeast Asian islands of Flores, Sulawesi and Luzon, and a Middle Pleistocene colonization by Homo erectus was initially proposed to have occurred on these islands. However, until the discovery of Homo floresiensis in 2003, claims of the presence of archaic hominins on...
Article
Ramification is the term used to classify branched productive sequences in which a functional item (the flake) was exploited as a productive item (the core). This technological behaviour was present in Europe and the Levant beginning in the Lower and Early Middle Palaeolithic, but ramified productions were intensely developed in the Late Middle Pal...
