IPHES massive participation in the most important world congress on Prehistory

A total of 16 sessions are coordinated by the center, which has received 265 communications, more than the 16.5% of the total that fill up the Congress.

Although their contributions are mainly focused in Atapuerca and Orce, IPHES members present almost all the topics covered at this meeting.

The work in China, the archaeology of fuel or the neanderthal behavior observed in the Abric Romani are other issues to highlight

In total, 1,653 communications by 3,032 different authors from the five continents will be presented

From September 1st to 7th the XVII World UISPP Congress (Internationale des Sciences Préhistoriques et Protohistoriques) is celebrated in the city of Burgos, association that brings together thousands of scientists, researchers and academics related to these disciplines around the world. The congress, organized this time by the Fundación Atapuerca has 115 scientific sessions, both of Prehistory and Protohistory, in which 1,653 communications by 3,032 different authors from the five continents are presented. These sessions are presented simultaneously in 24 classrooms of the Law and Economics Faculties of the Burgos University.

In this framework, the IPHES (Institut Català de Paleoecología Humana i Evolució Social) is involved in the organization of sixteen sessions, which has received a total of 265 communication proposals, of which 32 are posters and the rest oral presentations, representing more than the 16.5% of the total Congress communications. Some of them are dedicated to present the current research in archaeopaleontological ensembles led by members of the center, as in the case of Atapuerca and Orce. In general, however, reproduce the thematic offer of the congress itself, as the IPHES is one of the most productive in its field and also in all Quaternary periods research and in much part of the problem. 40 of the 60 members form the institue will attend, between researchers and technical personnel; the latter has also an important role in the organization of the UISPP.

To the two scientific sessions mentioned above must be added a third one dedicated to the regional record issues, about prehistoric archaeology in China. This session is part of the cooperation project with the Pekin Institute of Paleontology that will developed a variety of themes related to technology, cognition, culture and environment.

A group of four sessions will focus on hot issues about the world of human behavior over the time. One of them about the technological changes during the Low and Middle Pleistocene transition will be discussed. A second, perhaps the most original, present the research in archeology of fuels, with an emphasis on social and environmental factors that influence the decisions of human behavior in this area. The third deals with the economic behavior of groups of hunter-gatherer-fishers of coastal resources. Finally, a fourth is dedicated to the neanderthals; the only session of the whole Congress which aims to analyze this species. It will highlight the Abric Romani site (Capellades, Barcelona), one of the most important records of the neanderthal behavior.

The peopling of the continents

Two more sessions are dedicated to assess the macroregional peopling of the continents. One is only related to Europe and the first European settlements, addresses to discuss the assumptions and records recently brought to light. Obviously, it will be complementary to those dedicated to the specific record of Orce and Atapuerca. The second wants to be dedicated in a wide manner to the statistical and virtual models to explain the Pleistocene human dispersals. As in the session of China archeology, this is also part of an international cooperation project with the IPHES, in this case with the Consejo Nacional de Investigaciones Científicas y Técnicas (CONICET) and the Instituto de Investigaciones en Diversidad Cultural y Procesos de Cambio (IIDyPCa), both from Argentina. Obviously, the American record will be specially treated.

Cultural Change

The IPHES also participates in the organization of two sessions that have as research axis the chronostratigraphic models. They are two very different proposals. A biochronological and paleoecological issues of the European Quaternary as a whole, although focusing on the more ancient times. This session will review the reconstruction of biostratigraphic models with the records of anthropic presence while the second will present the chronological and stratigraphical data concerning to the cultural change behind the Middle and Upper Paleolithic transition in western Europe.

During the Congress there will be a single session dedicated to paleoanthropology, and will be coordinated by the members of the Atapuerca Research Team (EIA), among them there is a researcher from IPHES. Being, as we say, the only one dedicated to this discipline, will address diverse topics of current debate, without focusing on a specific issue.

Rock sheters and shepherds

The IPHES is also involved in a single session in the field of recent Prehistory with a discussion on the proposed use of the caves by shepherds communities from the Neolithic. It is intended to define the use patterns of these spaces and, in particular, the methodological issues and archaeological record associated with the pens. Of course, the record of the Mirador cave in Atapuerca will be analyzed.

As a research institute with significant analytical vocation, IPHES organized three sessions on analysis methodologies. One will deal with the study of quartz industries throughout the archaeological record, highlighting common problems and ways to address them. Finally, of the three sessions of the commission on the use-wear traces study, IPHES members are involved in the organization of two of them, one dedicated to the current trends and modernization of this discipline and the other to the wear determination associated to the handles use. Here sickles and projectiles will be particularly discussed. This field of study has been always entirely transverse, so all periods of Prehistory and Protohistory have place.

Opening act and magistral conferences

The opening act for the XVII World UISPP Congress will take place on Monday September 1st at 11 am at the Hospital del Rey auditorium of the Burgos University.

Six major keynotes are expected. One of them, which is on Wednesday September 3th, at 20 hrs at the Auditorio Fórum Evolución, open to general public, is entitled “La evolución humana en las Américas. Paralelismos globales y particularidades desde el último continente colonizado” and imparted by José Luis Lanata, world’s leading authority on prehistoric human migrations”, Director of the Instituto de Investigaciones en Diversidad Cultural y Procesos de Cambio de la Universidad Nacional Río Negro (Argentina) and member of the Red Orígenes impulsed by the IPHES to create synergies with the Latin American centers.

The 700 new prehistoric remains found in Cova Eiros this summer will help to the better understanding of some aspects of the neanderthal life

Cave bear remains that used the rock shelter to hibernate are notable

Anthropic action is confirmed through the cutmarks on the animal bones consumed by the hominids

This summer the work has been developed by an 11 members team which have excavated in the Cova Eiros (Lugo, Galicia, Spain), resulted in over 700 new prehistoric remains, including fauna and lithic tools that will help to better understand some aspects of the daily life of the neanderthal communities that inhabited that area between 84,000 and 118,000 years ago.

The excavation has been co-directed by Xosé-Pedro Rodriguez and Arturo de Lombera, member and collaborator of the IPHES (Institut Català de Paleoecologia Humana i Evolució Social) respectively, under the research project directed by Ramón Fábregas form the Grupo de Estudos para a Prehistoria do Noroeste (GEPN) of the Universidade de Santiago de Compostela (USC). The team was made up of people from both institutions, experts and students from the Erasmus Mundus Master in Quaternary Archaeology and Human Evolution imparted at the Universitat Rovira i Virgili of Tarragona, thanks to the top-level research projects developed by the IPHES.

Arturo de Lombera said that this year the findings in Cova Eiros “provide good information about some aspects of neanderthal communities, for example, their technology or the environmental context they knew, as we have very few evidence in the peninsular northwest for this period”.

One of the objectives for this year excavation has been to reach level 3 on the entire surface of Cova Eiros, dating 84,000 years ago, that corresponds to the latest occupation of the neanderthal populations identified in this cave. It has been also developed a 4 square meters intervention, in level 4, with an older chronology, about 118,000 years, also assigned to the Middle Paleolithic.

“At both levels we have found many faunal remains, especially cave bears who used the place to hibernate, animal fossils with cutmarks, which confirm anthropic action, specifically its consumption by neanderthals. There is great a remains diversity, highlighting deer and horses, which are strongly fragmented and with evident anthropic intervention marks (cutting, fracturing bones, etc.).

Moreover, the traceology studies indicate the presence of related hunting activities (projectile points), fleshing and furs work activities, as well as the animals processing and their products (furswork).

Pieces mainly made in quartz and quartzite

Respect to the lithic industry, “We found pieces mainly made in quartz and quartzite, of local origin within 3 km in radius, although some of these second mentioned might have a more distant origin, possibly from shores and channels located more than 10 kilometers away”, says Arturo de Lombera. These materials are made of a much higher quality, and moved to the site. Mostly produced with Levallois technology (a complex flaking procedure), which is preferably carried out on this material because of its higher quality, whereas in the local quartzites and quartz, expeditious exploitation methods were mainly applied. This differential management strategy of the raw materials based on the quality is typical of neanderthal communities and indicates the high degree of knowledge they had about the lithological offer in the environment, and the existence of planning strategies for their activities.

Funerary activity

Furthermore, a ceramic piece with printed decoration, waiting for the laboratory studies, is probably dated around 4,700 years ago, as it has been found at the same level where in 2011 a few remains from the same vessel were recovered, and that are probably related to the funerary activity identified in the cave, inferred from the human remains found in the cavity with that age; the ceramic could have been part of the grave goods of the burial that took place during the recent Prehistory. In addition, this style corresponds to the stylistic modes from that period (cardial impressed decoration).

In Cova Eiros the systematic excavation has been developed since 2008, under the project of the Middle Pleistoce/Holocene of the eastern regions of Galicia  (MINECO-HAR2010-21786). The work that has been carried out shows the importance of the Middle Paleolithic in Galicia, which is still an unknown period. There are just a few sites and this is the only cave, where the preservation of the organic remains it’s very important, the rest of the sites are mainly outdoor, with acid soils that makes the materials preservation more vulnerable and where most of the time are not preserved.

The Cova Eiros sequence is also very complete, since it has preserved both, tools and faunal remains (lion, deer, horses, chamois, etc.) both hunted by neandethals and sapiens. “This brings a lot of information where we can compare subsistence patterns and technology of both species, as well as to characterize the paleoenvironmental setting in the eastern of Sierras de Galicia”.

Public presentation in Tunisia of the oldest urus skull ever found and new excavation campaigns in Oued Sarrat

Recently in the Pleistocene site of Oued Sarrat (Tunisia), with an approximately age of 700,000 years, it has been developed a new exploration and excavation campaign under the direction of Professor Narjess Karoui-Yaakoub, of the Cartage University, and the ICREA (Institució Catalana de Recerca i Estudis Avançats) research Professor, assigned to IPHES (Institut Català de Paleoecologia Humana i Evolució Social), Bienvenido Martínez-Navarro. Coinciding with the end of this campaign a public presentation was conducted, in the City of Sciences of Tunis (Cité des Sciences), of the site and the oldest urus skull finding (primitive bull and the actual ancestor) about 700,000 years old, as was announced a few months ago in the Quaternary Science Reviews journal.

“In this campaign it was carried out a small systematic excavation and continued the survey work and the recording of new fossils along the Sarrat River basin, with a continuous outcrop over 5 km”, says Bienvenido Martínez-Navarro. Work has been done in the lower swampy black levels, corresponding to the base of the Middle Pleistocene (about 700,000 years old), mainly composed by clays very hard to erode, through which the river runs intensely forming large meanders, raising and revealing every year a very good fossil record of large mammals, including: bulls (Bos primigenius), horses (Equus sp.) rhinoceros (Ceratotherium simum), gazelles (Gazella sp.) orjackals (Canis sp.), as well as a great amount of microvertebrates (micromammals, amphibians, reptiles and fish), associated with the presence of the Acheulean type lithic industry, as in the Upper Pleistocene gray-brown fluvial terraces, overlapping the black basal levels, where an abundant fauna of large mammals also dominated by the presence of bulls (Bos primigenius), gazelles (Gazella sp.), elephant remains, and large carnivores such as lions and large size (Panthera leo) associated with the Aterian type lithic industry, dated between 30,000 and 70,000 years, chronologically equivalent to the European Middle Palaeolithic (Mousterian).

Also, a small excavation was carried out at the lower levels, finding Bos primigenius and more acheulean industries. To this we must add that during the survey, numerous remains of other large mammals were found from both, the Middle Pleistocene and the upper levels.

Is notable the presence of a complete camel metatarsal discovered in the levels of the Late Pleistocene, first record of this species in the site. It is also the first time that fossil wood residues were found in the lower black levels.

“These data will expand the paleobiological information of the site and promote the better understanding of the environment in which the acheulean hunters, 700,000 years ago, and aterian industry between the 30,000 and 70,000 years were developing in northern Africa” says Martínez-Navarro.

On the other hand, it was presented in a crowded public event organized at the Cité des Sciences of Tunis, the oldest bull skull ever found (Bos primigenius). It was in the lower level of Oued Sarrat, dated at 700,000 years. To the event assisted: numerous tunisian academic authorities and scientists from the universities of Carthage, Tunis and Sfax, as from the National Office of Mines (all involved institutions in the research), several parliamentarians from Kef, province where the deposit of Oued Sarrat is located, and the Ambassador of Spain in Tunisia, Juan López-Dóriga.

The IPHES is a new research institute of the Rovira i Virgili in Tarragona

One of the main objectives is to provide added value to the academics

The IPHES (Institut Català de Paleoecologia Humana i Evolució Social), created in 2006 and directed by the archaeologist Eudald Carbonell, is already a new Institute of the Universitat Rovira i Virgili de Tarragona (URV), after the approval of the Conselleria d’ Economia i Coneixement de la Generalitat de Catalunya, dated on 8 July and published in the Diari Oficial de la Generalitat (DOGC) the last August 4th.

Thereby concludes the formalization of a process that began in May 2013 with the signing of an agreement between such counseling and the URV to achieve this recognition, which once published in the DOGC is already fully effective.

The IPHES, located at the campus of the URV Sescelades, whose main objective is to become a center of international reference in the development of research, teaching and transference in the different branches of the study of evolution and human behavior. In this context, from now on it will enhance the teaching area, ensuring the scientific quality and providing added value.

The approval gives a new context to a rich activity that takes place since 2004 in which IPHES researchers elaborate the program to develop the first URV masters Erasmus Mundus in cooperation with three more European universities. Since 2013 it has been also added the Erasmus Mundus doctorate in Quaternary and Prehistory. The expedition of the degree corresponds to the URV.

With regard to the faculty, teaching will be carry out by the researchers from both institutes, IPHES and URV.

The agreement also provides that the IPHES, and in particular, its teaching staff have access to the support services to help in the study and teaching, research and university extension of the URV.

Its origins

Although IPHES was born 8 years ago, its origins go back to 1988, when the archaeologist Eudald Carbonell, co-director of the Equipo de Investigación de Atapuerca (EIA), arrived to Tarragona to join as a Prehistory Professor in the Universitat de Barcelona delegation (UB). Since then, he has worked hard to promote a transdisciplinary team with international projection on the study of human evolution. The first steps were taken with the Grupo de Autoecología Humana when the Universitat Rovira i Virgili de Tarragona was created in 1991, where he is a Prehistory Professor. Currently, IPHES is among the three best research centers in the world in its field.

Thousands of new remains found in the Abric Romani support the organizational capacity of the neanderthal communities

This year has been excavated a new rich level of fossil and with an antiquity over 58,000 years

PHOTOS – CATALAN – SPANISH

58,000 years ago the neanderthal populations that lived in the Abric Romani in Capellades (Barcelona), a key site for the study of this species, left thousands of archaeological remains during their occupation. This has been found during the excavation campaign that has taken place this month and ends the 24th, directed by the archaeologist Eudald Carbonell, director of IPHES (Institut Català de Paleoecologia Humana i Evolució Social). The results support the organizational skills that these prehistoric communities had.

The new fossils, localized, but which have not been removed or fully documented, have been obtained thanks to the work of a team of about 50 people, including researchers of IPHES, centers in other countries and also students from all around the world, who have been dedicated to discover the Q level of the Abric Romani, spending all efforts to reach the surface in an area of ​​about 140m2.

“It should be noted that only in the ceiling level, basically localized, but unexcavated until the depth, have been recovered thousands of lithic pieces and fauna remains. Moreover abundant hearths of rooms were detected next to the wall, as from other types also, biggers and in association with the abundant presence of burnt bones, which it seems that those hominids began to move through the central part of the site”, says Eudald Carbonell. “This distribution or space specialization is the clear evidence of the organizational capacity of the neanderthal populations, in the context of complex behavior that we have always defended,” he added.

One possible room

Eudald Carbonell has advanced: “The evidence available today seems to indicate that we are dealing with the remains of what was a neanderthal room, where different daily life activities were developed reiteratively, such as tools processing”.

It is also a referential site or a central camp where the remains of the hunted animals for the consumption of the whole group were transported. Both, the amount of faunal remains and the diversity of raw materials found indicate that the Abric Romani was more or less occupied for longer periods of time and repeatedly.

A new type of employment

This feature represents a new shift in the type of occupation of this rock shelter, because the level excavated during the last year’s campaign was the product of short occupations. However, we should expect the excavation of the next year to see if the new hypothesis is valid. At least, we can say that the Q level is included among the richest of those which have been intervened until now in the Abric Romani.

With regard to the lithic tools discovered this year, are produced on a wide range of raw materials, including chert, limestone and quartz, as the most exploited types of rocks. In this assemblage there have been a lot of denticulates  and other types of retouched pieces.

Both, these and the already recovered remains for more than thirty years of excavation at the Abric Romani, “clearly show that neanderthals were active hunters”, stated Eudald Carbonell. “The subsistence strategies at this site were intended for hunting large ungulates, mainly horses and deer”, he points out.

Paleolithic inhabitants of Mediterranean Spain may have included snails in their diet 10,000 years earlier than previously thought

PHOTOS – SPANISH

Paleolithic inhabitants of the Iberian Mediterranean region may have eaten snails 10,000 years earlier than their Mediterranean neighbors, according to a study published August 20, 2014 in the open-access journal PLOS ONE by Javier Fernández-López de Pablo from Institut Català de Paleoecologia Humana i Evolució Social (IPHES) and colleagues.

Snails were widespread in the Late Pleistocene and Holocene, but it is still unknown when and how they were incorporated into human diets. The authors of this study found land snail shell remains from ~30,000 years ago at a recently discovered site of Cova de la Barriada (Benidorm, Spain). To better understand if the inhabitants may have eaten snails, the researchers investigated patterns of land snail selection, consumption, and accumulation at the site, and then analyzed the shells decay, fossilization process, composition, and age at death by measuring the shell size.

Stone tools and other animal

Scientists found groupings of complete shells from a large land snail species at three layers of the site, corresponding to different time points dated 31000-26900 years ago. The adult snails were close to prehistoric human-constructed structures that may have been used to cook the snails, along with stone tools, and other animal remains that were likely roasted in ambers of pine and juniper under 375 ºC. The authors posit that these results point to previously undiscovered patterns of invertebrate use and may highlight a broadening of the human diet in the Upper Paleolithic in the Mediterranean basin. In neighboring Mediterranean areas, eating land snails didn’t appear until about 10,000 years later, which may make these newly found snail shells the oldest known evidence that ancient human populations used them as a food resource in Europe ~30,000 years ago.

The Homo sapiens deposited at El Mirador Cave, in Atapuerca, about 4500 years ago, had genetic affinities with the Near East and Germany

According to the mitochondrial DNA analysis, that for the first time, has been carried out on the fossil remains found at this site

The work was done by the researcher team lead by Carles Lalueza-Fox, from UPF, with the participation of the IPHES and now published in the journal PLOS ONE

During the Middle and Final Neolithic there was a common genetic signal in Central and Western Europe, although in the Chalcolithic the scene becomes much more heterogeneous

CAPTIONS CASTELLANO – CATALÀ – PLOS ONE OPEN ACCESS

Around 4,760 and 4,200 years the Mirador Cave, in Atapuerca (Burgos), functioned as a burial site, where at least 23 individuals of the species Homo sapiens were deposited. In 19 of them, the mitochondrial DNA was extracted in order to know where they came from and with who were they genetically related, among other issues. A recent study published in the PLOS ONE journal brings some light to this question. According to the results, those specimens have genetic affinities with populations in the Middle East and Germany.

This is the first DNA analysis performed on the remains discovered in El Mirador. The research was conducted as part of a wider work on the genetic composition of the European populations contemporaries to the Bell-Beaker culture, although Homo sapiens from this cave did not belong to this technical tradition, as they did not manufactured or used the same ceramic type.

“This research shows that the Chalcolithic people at El Mirador has affinities with the Near East groups and temporary fits in the Middle and Final Neolithic populations of Germany, as the Rossen Salzmünde and Balberge cultures, but has no relationship with the contemporary Bell-Beaker culture”, explain Marina Lozano, IPHES researcher, which is among the signatories of the article, together with Josep Maria Verges, also an archaeologist at the Institute.

Thus, it´s confirmed that during the Middle and Final Neolithic there was a common genetic signal in Central and Western Europe, but throughout the Chalcolithic the scene becomes much more heterogeneous with the presence of more groups.

The traditional hypothesis indicates that the Bell-Beaker culture developed in the European Atlantic coast and spread from there to the rest of Europe. The discovery of ancient sites in Portugal with the presence of ceramic from that culture, suggests its origin in the Tagus River area.

The socioeconomic basis of this populations was livestock (herds of goats and sheeps), the cereals production (wheat and barley, and some legumes) and occasionally the animal part of the diet was complemented by hunting.
