Stone tools and faunal remains are abundant in the archaeological record, serving as key focal points for research and important features of museum exhibitions. Nevertheless, they are under-represented in the conservation literature. This article reports on the conservation of over 2,000 finds from the Early Pleistocene site of Barranc de la Boella...

Due to its long occupation throughout the Middle Palaeolithic and the abundance of its pyrotechnological evidence, the Abric Romaní rockshelter (Capellades, Barcelona) provides an ideal setting for studying Neanderthal fire use. We conducted an archaeomagnetic study of four hearths from Level R (ca. 60 ky BP). Rock magnetism experiments, including...

Who the first inhabitants of Western Europe were, what their physical characteristics were, and when and where they lived are some of the pending questions in the study of the settlement of Eurasia during the Early Pleistocene epoch. The available palaeoanthropological information from Western Europe is limited and confined to the Iberian Peninsula...

En este artículo se presentan los trabajos arqueológicos desarrollados entre 2012 y 2015 en la Cova de Les Borres (La Febró, Tarragona).

Osseous industry has been observed at an increasing number of Neanderthal sites. Bone fragments were used for practical purposes, and a range of bone shaping techniques were employed. The variability of bone tools observed in different assemblages reflects considerable functional diversity. However, no bone spear points have been reported from thes...

The emergence of the mode 2 technocomplex, traditionally characterized by the development of large cutting tools (LCTs) or standardized large-shaped tools, has also implied a range of new technological behaviours. These include enhanced raw material management, more sophisticated knapping strategies, and transport patterns, among other innovations....

This paper presents the zooarchaeological, technological, use-wear, and spatial analyses of the earliest sedimentary subunits of TD10 (TD10.3 and TD10.4) of the Gran Dolina site (Sierra de Atapuerca, Burgos, Spain), dated to c. 400 ka. Both units have yielded Acheulean technology, with occupational models characterized by the superimposition of mul...

The Early Pleistocene site of Quibas, located in Sierra de Quibas (Murcia, Spain) was discovered in 1994 and has since then provided abundant material of typical Epivillafranchian taxa. This biochron belongs to the Early-Middle Pleistocene Transition (1.2 – 0.78 Ma), characterised by a change in orbital cyclicity from a 41 kyr cycle to 100 kyr that...

Since the oldest known Acheulean lithic techno-typological features in Europe were reported at the site of Barranc de la Boella (Tarragona, Spain), continuous fieldwork has been conducted there in archeological deposits of the late Early Pleistocene age (0.99–0.78 Ma). As a result, excavations in two of the three open-air localities have significan...

The Sant Genís Formation is located in the NE of the Iberian Peninsula (Catalonia, Spain) and is dated to the Priabonian (upper Eocene), being part of the evaporitic formations of the margin of the Ebro Basin. It is formed by a succession of sandy lutites, occasional limestone layers, marls, and local stratified gypsum and cherts, including the San...

Cal Sitjo is a new archaeological sequence located in a chert-rich region of the NE Iberian Peninsula, in the town of Sant Martí de Tous (Anoia, Barcelona). The area has undergone significant anthropisation and several archaeological sites (e.g., Vilars de Tous), quarries and workshops for the exploitation of chert (e.g., La Guinardera) have been d...

The BB specimen is an upper right canine belonging to a male of the primate M. sylvanus. The agreement among the qualitative characteristics of the tooth and the chronology of the site suggest its identification as M. sylvanus cf. florentina, although the lack of consensus on the validity of the proposed subspecies and the large biometric overlap d...

The study of European Pleistocene Hippopotamus presents unresolved questions and a lack of consensus among specialists being matter of hotly debate in the last decades. The number of taxa, their geographical and chronological distribution and their palaeobiological affinities are still under evaluation. The present work presents the results of comp...

Badgers belong to the genus Meles Brisson, 1762, which comprise four extant species (M. anakuma Temminck, 1844, M. leucurus (Hodgson, 1847), M. canescens Blanford, 1875, and M. meles (Linnaeus, 1758)). The genus is included in the subfamily Melinae Bonaparte, 1838, a polyphyletic group of Eurasian mustelids whose evolutionary relationships need fur...

The application of dental wear study to murids has always been ruled out because of their omnivorous diet, which does not leave significant wear on the dentition. Nevertheless, in our work we select Apodemus sylvaticus (wood mouse) as the object of study for several reasons: its seasonal diet, its ability to resist the gastric juices of predators,...

The Lower Pleistocene site of Quibas, in Sierra de Quibas (Murcia, Spain) was discovered in 1994 and has since then provided abundant material of typical Epivillafranchian taxa. This biochron belongs to the Early-Middle Pleistocene transition (1.2 – 0.78 Ma), characterised by a change in orbital cyclicity from a 41 kyr cycle to 100 kyr that intensi...

This poster shows the conservation of a bird feather imprint in travertine rock. The specimen was recovered from Level Ra (ca 62 Ka BP) of the Middle Palaeolithic site of Abric Romaní (Capellades, Barcelona, Spain). The rock presented some granular desintegration. To stop the decay, the travertine was consolidated with the silica nanoparticle-based...

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...

In the middle Tagus, which defines as a sort of ecotonal area where almost all geological substrata that exist in western Iberia also occur, within a range around 70 kilometres, one may now recognise a diversity of strategies undertook by various human groups, mostly oriented toward the intensification of the use of specific resources. While the re...

The Sima del Elefante site is located within the Sierra de Atapuerca karst system (Burgos, northern Spain), and forms part of a series of important Early, Middle and Late Pleistocene archaeological complexes that have been dated previously with luminescence techniques (Gran Dolina, Galería Complex, Sima de los Huesos, Galería de las Estatuas).

The TD6 unit of the Gran Dolina contains an assemblage of the Early Pleistocene, interpreted firstly as a home base. More recently has been proposed a transported origin of the remains according to the sedimentology. Following this model, the remains should be dragged or lagged in a predictable pattern related to their weight, density, shape, and s...

The open-air site of Cantacorbs is a Neolithic chert workshop located on a calcareous mountaintop plateau (1022 masl), overlooking one of the main routes through the Prades Mountains (Tarragona, NE Iberian Peninsula). The main characteristic of the site is the abundance of knapped lithic material on the surface, in which all stages of the blade pro...

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...

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...

Level M and sub-level Oa at Abric Romaní (Capellades, Barcelona, Spain) are showing various types of technological contexts. The chaines opératoires of level M show expedient strategies. The lithic assemblage of sub-level Oa is associated to hierarchized strategies and Levallois chaines opératoires. Chert is the most used rock (level M = 80.8%; lev...

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...

Small mammals, especially rodents, constitute valuable proxies for continental Quaternary environments at a regional and local scale. Recent studies have demonstrated the relation between the stable oxygen isotope composition of the biogenic phosphate from rodent teeth (δ18Op), and the oxygen isotope composition of meteoric waters (δ18Omw), which i...

The Middle-to-Upper Paleolithic transition in Europe covers the last millennia of Neanderthal life together with the appearance and expansion of Modern Human populations. Culturally, it is defined by the Late Middle Paleolithic succession, and by Early Upper Paleolithic complexes like the Châtelperronian (southwestern Europe), the Protoaurignacian,...

Ethological studies have shown that besides human groups, large-medium carnivores have bone-collecting habits. The research developed since the last half of the twentieth century has attempted to characterise the carnivore’s accumulations and to identify them in the archaeo-paleontological record. At present, we have diagnostic criteria that define...

Raw material provenance and procurement studies are an essential research line to infer landscape exploitation, mobility dynamics and territorial management among prehistoric hunter-gatherer groups. This paper proposes an original and intuitive method, the chert abundance ratio, aimed at quantifying lithic resource occurrence in the landscape while...

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...

Practically all archeological assemblages are palimpsests. In spite of the high temporal resolution of Abric Romaní site, level O, dated to around 55 ka, is not an exception. This paper focuses on a zooarcheological and taphonomic analysis of this level, paying special attention to spatial and temporal approaches. The main goal is to unravel the pa...

The late Early Pleistocene site Barranc de la Boella provides an unparalleled opportunity to assess the context of the activities of the hominin populations that inhabited the Iberian Peninsula at 1 Ma. Recently, strong evidence for access to mammoth meat has been described at the Pit 1 locality. At the la Mina and el Forn excavation areas, little...

Coprolites are commonly identified in the Pleistocene archaeo-palaeontological record. They have often been described as indirect evidence for the presence of carnivores (usually hyenids) during the formation of a depositional sequence. However, coprolites are a much larger source of information that can provide data relating to factors affecting a...

This paper presents a synthesis of the chronological results obtained in the "Investigación cronoestratigráfica de los soportes y recubrimientos de las pinturas rupestres de la Sierra de la Pietat o Godall (Montsià, Tarragona)", performed during the project "Estudio cronoestratigráfico de los soportes del Arte Rupestre del Levante Español” (2008-20...

The research for referential data on current livestock contexts is essential for correctly interpreting archaeological records documented in prehistoric livestock spaces. Experimental programmes such as the one begun in 2014 in the Mas del Pepet pen (Rojals, Tarragona) has permitted an understanding, among other matters, of fold characteristics acc...

Recent exploratory drilling at Abric Romaní reveals that carbonate tufas similar to the archeologically rich levels excavated to date extend at least 30 m beneath the current base of excavation.

Here we present a preliminary approach to the taphofacies analysis of the El Forn Lower Pleistocene site. Since 2007, tree open air archeo-paleontological sites have been excavated at Barranc de la Boella (Tarragona, Spain): La Mina, Pit 1 locality and El Forn, dated at around 1 my old. Fossil mammals and lithic remains point to these sites as the...

Barranc de la Boella is made up of several open-air late Early Pleistocene archaeological sites (Pit 1, La Mina and El Forn) the formation of which is related to a deltaic sedimentary environment. Its age makes it a key site for studying the behavior of the early hominin groups of the Iberian Peninsula and western Europe and the ecological context...

Datos paleoambientales inferidos a partir de los micromamíferos del Pleistoceno Inferior del yacimiento del Barranc de la Boella (Tarragona, España)

Several studies have attempted to identify diagnostic criteria for distinguishing between evidence of trampling and cut marks, two common modifications at archaeological sites. These studies have brought to light, with relative precision, the features that identify and differentiate the two types of modifications. However, few studies differentiate...

In 2007, remains of Mammuthus meridionalis and 334 lithic artefacts were recovered in level 2 of Barranc de la Boella. The presence of M. meridionalis allows us to assign an age older than 700 ka to this level, which represents one of the few sites of this age with palaeontological remains associated with lithic industry. It also enables us to shed...

The first arrivals of hominin populations into Eurasia during the Early Pleistocene are currently considered to have occurred as short and poorly dated biological dispersions. Questions as to the tempo and mode of these early prehistoric settlements have given rise to debates concerning the taxonomic significance of the lithic assemblages, as trace...

Several recent works have suggested that Neanderthal spatial behaviour may have been more complex than previously thought. One of the archaeological sites that has contributed the most data on this issue is the Abric Romaní (Capellades, Barcelona, Spain). This paper focuses on the study of Neanderthal ac-tivities related to animal resources that to...

We present the results of prospecting in the NE of the Iberian Peninsula, with the aim of identifying the siliceous sources potentially used by the populations that occupied the marginal basins of the Ebro depression during the Middle and Upper Palaeolithic.We intend to define the main characteristics of the cherts in the region studied, taking int...

The Sierra de Atapuerca, northern Spain, is known from many prehistoric and palaeontological sites documenting human prehistory in Europe. Three major sites, Gran Dolina, Galería and Sima del Elefante, range in age from the oldest hominin of Western Europe dated to 1.1 to 1.3 Ma (millions of years ago) at Sima del Elefante to c.a. 0.2 Ma on the top...

The study of Mimomys savini material from the Spanish sites of Barranco León and Fuente Nueva 3 (Granada), Gran Dolina (Atapuerca), Vallparadis (Barcelona) and La Boella (Tarragona) shows evolutionary trends in the dental morphology of this species within the Lower and early Middle Pleistocene. The data obtained from each site were ordered on the b...

The correlation between environmental and cultural changes is one of the primary archeological and paleoanthropological research topics. Analysis of ice and marine cores has yielded a high-resolution record of millennial-scale changes during the Late Pleistocene and Holocene eras. However, cultural changes are documented in low-resolution continent...

Las excavaciones llevadas a cabo en el yacimiento de la Cova de Dalt del Tossal de la Font en la década de 1980 pusieron al descubierto un importante relleno kárstico del Pleistoceno Superior.

The human use of fire generates a cultural sedimentary record that can be used to characterize prehistoric activity areas. The aim of this paper is to develop a field guide for recognizing and describing combustion structures. The use of fire as suggested by the results of ethnoarchaeological and prehistoric archaeological studies has served as the...

Pleistocene foragers used several prey acquisition and processing strategies. These strategies and their associated decisions are elucidated by taphonomic studies that cover animal transport, modifications by different agents and archaeological remains. Interpretative models of archaeological sites are by necessity based on natural and experimental...

Human cannibalism is currently recorded in abundant archaeological assemblages of different chronologies. The TD6 level of Gran Dolina (Sierra de Atapuerca, Burgos), at more than 800 ka, is the oldest case known at present. The analysis of cranial and postcranial remains of Homo antecessor has established the presence of various alterations of anth...

El yacimiento de Galería es uno de los múltiples depósitos localizados en la Sierra de Atapuerca (Burgos, España). Su registro arqueopaleontológico se enmarca cronológicamente entre los c. 500 ka y los 180 ka. Diferentes estudios multidisciplinares han puesto de manifiesto que Galería funcionó como una trampa natural para los animales que merodeaba...

The earliest hominin occupation of Europe is one of the most debated topics in palaeoanthropology. However, the purportedly oldest of the Early Pleistocene sites in Eurasia lack precise age control and contain stone tools rather than human fossil remains. Here we report the discovery of a human mandible associated with an assemblage of Mode 1 lithi...

On the northwest slope of the hill, Puig Marí (Maçanet de la Selva), a volcanic cone, a Palaeolithic site was found in the open air in stratigraphic context. The complex is associated with a basalt outcrop that was exploited by the hominids as a source of raw material. The archaeological material was recovered in a homogeneous deposit with no archa...

The sediments of the TD6 level of Gran Dolina Cave at Sierra de Atapuerca, Burgos, Spain, consist of a series of mud flows with angular clasts. The TD6 deposit has two parts: an upper part, known as the Aurora stratum, which yields Homo antecessor remains, and a lower part with rather homogeneous sediment. The excavation of TD6 level did not reveal...

New U-Series and C14 (AMS) dates are provided for the Abric Agut (Capellades, Barcelona, Spain). This site was previously considered to be of Middle Palaeolithic age according to the characteristics of the lithic assemblage. In addition, human teeth were uncovered and attributed to neandertals. However, radiometric dating clearly indicates a Late P...
