Residential camps from around 9,000 years B.P. and new Neolithic human occupation evidences, have been found in Villena

This has been confirmed by fieldwork conducted at Arenal de la Virgen and Casa Corona archaeological sites. These actions are framed in the development of the ERC project PALEODEM, aimed at investigate the relationship between population dynamics and climate change and conducted by Javier Fernández López de Pablo from IPHES

A team of 15 archaeologists and 20 volunteers has worked at the Arenal de la Virgen and Casa Corona archaeological sites in Villena (Alicante, Spain). This fieldwork campaign represents a first excavation phase and have provided relevant data for the research that is being carried out in the scope of the European research project PALEODEM, on climatic and demographic changes developed from the IPHES (Institut Català de Paleoecología Humana i Evolució Social). At both sites, the excavation has yielded evidences of human occupations during the Mesolithic and Neolithic periods, between 9,000 and 5,000 years ago.

This first excavation phase included in this project began on 1 March and ended on 30 June, taken place during 4 months of uninterrupted fiekdwork on these sites.

Hearths, small stone-pavings and post-holes have been documented among the  habitat structures. In the Arenal de la Virgen, abundant remains of lithic industry, land snails and some ornaments, have been recovered. In Casa Corona, besides lithic and malacological remains, numerous Neolithic sherds have been found. In addition, large numbers of sediment samples have been collected for paleobotanical, geoarchaeological and micromorphological analyzes in both sites. This information will allow the reconstruction of the landscape and their dynamic variations in which the last hunter-gatherer populations and the first farmers lived at this zone of the Mediterranean façade.

“Altogether, the ensemble of evidences obtained in this excavation will contribute in a very significant way to enhance our understandingof the demographic and socio-economic dynamics that took place during Mesolithic and Neolithic times, in its paleoclimatic and paleoenvironmental context, “commented Javier Fernández López de Pablo, archaeologist and director of the PALEODEM project (ERC Co-Grant No. 683018), funded by the European Research Council under the Horizon 2020 program.

Villena City Council, within the framework of the collaboration agreement signed in 2016 with IPHES, has provided logistical support by providing technical resources and municipal infrastructures.

Increases the interest of archaeobotany as a tool for the understanding of past societies and their environmental setting

As a consequence IPHES has organized a seminar for exchanging knowledge among students and researchers 

Through a combination of theoretical sessions and practical activities to acknowledge in situ some of the Tarragona coastal landscapes  

videowebphotosespañolcatalà

Archaeobotany is a field of knowledge from archaeology that permits to understand past vegetation and climate as well as the use and management of plants such as human and animal food, firewood, building material or technology. This knowledge is acquired throughout different disciplines such as palynology that studies pollen; anthracology, charcoals; phytoliths studies, and carbonized seeds and fruits studies.

Since a few years ago, there has been an increase of the interest among students and researchers to use theses disciplines due to the good results that provide for the study of past societies and the environments in which they lived. That is the reason why, the Archaeobotany Unit of IPHES (Institut Català de Paleoecologia Humana i Evolució Social) carries out along 2017 the I Archaeobotany Seminar. It has been organized by  Aitor Burguet-Coca, Fundación Atapuerca Fellow at IPHES, and Ethel Allué,  researcher from this research center.

The third session consisted on a botanical excursion to the Bosc de la Marquesa (Platja Llarga, Tarragona), that permitted to acknowledge the littoral forest communities

This seminar has the aim to share and debate the main archaeobotany issues and challenges, as well as to become a meeting spot for IPHES members working on this field. The organizers outline: “During the last year there’s been an increase of the interest in the different archaeobotany disciplines by students and researchers. This has led to have a critical mass at IPHES that at present is carrying out studies on archaeobotanical records, undertaking outstanding contributions based on these records”.

The seminar sessions are organized throughout the comment and debate of publications, excursions to places with a botanical interest and presentation of case studies. The two theoretical sessions were dedicated to the macro and microremains sampling and the quantification of archaeobotanical remains. The third session consisted on a botanical excursion to the Bosc de la Marquesa (Platja Llarga, Tarragona), that permitted to acknowledge the littoral forest communities, through the explanation by Francesc Burjachs ICREA researcher at IPHES. The last two sessions will take place in the fall and will be focused on the interpretation of archaeobotanical remains and the presentation of case studies.

The challenge of reassembling archaeological remains to understand life in Prehistory

From around the world, Tarragona is bringing together experts in reassembly, in a workshop that will take place from 9 to 11 May at URV’s Campus Catalunya

This technique allows us to understand what the economy was like, whether hominid groups recycled, and their social organisation

The IPHES will provide new information from Neanderthal communities that lived in Abric Romaní and around Sierra de Atapuerca

The event is sponsored by the Wenner-Gren Foundation, which funds research of excellence

An archaeological site is the result of a series of events that overlap at different levels through time. Archaeological remains generated by bone breaking and the sculpting of stone blocks are deposited in each of these strata. Refitting the pieces belonging to the same bone or block is an arduous task, but very useful for understanding an endless array of aspects related to human evolution.

With the aim of exchanging experiences, understanding the multidisciplinary applications of reassembly, and its reconstruction in 3D, as well as agreeing on criteria for its use, an international workshop is being held that will bring together the experts in this field. Entitled The Big Puzzle 30 Years After: A shared, multidisciplinary, Palaeolithic perspective, it will take place from 9 to 11 May, in Sala de Graus on Campus Catalunya at the Universitat Rovira i Virgili (URV), in Tarragona.

The title refers to the conference held three decades ago at the Monrepos Archaeological Research Centre and Museum in Neuwied, Germany. It was there that the importance of reassembly was first verified as a method for analysing the technical, economic and social behaviour of past populations. The publication from that conference and the data that has appeared since, have shown not only that reassembly is very useful for research, but have also led to new lines of investigative work.

The workshop is being organised by Francesca Romagnoli, a Marie Curie researcher at the IPHES (Institut Català de Paleoecologia Humana i Evolució Social), and Manuel Vaquero, an IPHES member and professor of Prehistory at the URV, as part of the EU’s H2020 Research and Innovation Program GA. 653667. It is being sponsored by the Wenner-Gren Foundation, a United States foundation that funds research of excellence in the field of anthropology, prehistory and the study of human evolution.

Reassembly with pieces from the Abric Romaní – IPHES

IPHES is deliberately linking this workshop to the symposium held in Germany in 1987, intending to reflect on the development of this technique over the last 30 years, and see whether the expectations generated at that time have been achieved. IPHES is a leader in the study of reassembly and has developed an analysis protocol that has enabled innovative work to be developed on the recycling, techno-economic, and social organisation of  Neanderthal communities. At the workshop, IPHES will present new data from the Abric Romaní site (Capellades, Barcelona) in the workshop, a world reference for work on the social organisation of Homo neanderthalensis, as well as from the Gran Dolina site in the Sierra de Atapuerca.

Reassembly allows researchers to identify what types of actions were carried out at a site, as well as their number and frequency, in addition to detecting the temporal and spatial relationships between the different events. For example, how a certain material was introduced into the archaeological site and where it came from, how tools were made, and so on. In this way one can ascertain aspects of the economy of hominid groups, the length of time they remained in a place, and the size and organisation of the human population that lived there. It also reveals whether the materials have been reused, and the importance of recycling to these hominids.

In addition, reassembly can be applied when analysing wildlife. This allows us to understand, for example, how humans shared and distributed food in the past.

These are just some of the issues that will be discussed in the workshop. It will be attended by top-level experts who apply reassembly in an interdisciplinary way to better understand what life was like in the Palaeolithic era. The participants include scientists from leading research institutes, such as UCL (University College London), and reference centres in the study of Prehistory, such as the University of Tübingen in Germany, the Autonomous Universities of Madrid and Barcelona, the University of La Laguna, the University of Ferrara, the Anthropos Museum of Brno, and the Monrepos Museum where the original conference took place.

Atapuerca site was the scene of the oldest case of bison communal hunting

A 400,000-year-old site in northern Spain provides evidence of ancient bison kill

Cooperating the hominids were organized and drive the animals to Gran Dolina cave site, place where the bison were trapped, slaughtered and butchered

This is confirmed in a report published in Journal of Human Evolution and there are who considered it one of the most relevant discoveries of the decade

Photoscatalà español – paper

It could be an ordinary journey 400,000 years ago, in Sierra de Atapuerca (Burgos, Spain), when the meals was not regulated by schedules like today and people had to get the food almost daily, taking what was found around them. As the hominids behaviour become more complex they also learned to organize themselves so as not lose opportunities and if it turned out well, they were reoffending.

In Gran Dolina archaeological site, specifically in TD10.2 layer, the IPHES (Institut Català de Paleoecologia Humana i Evolució Social) had already identified a large bison bones concentration (a truly bone bed), but now they can understand the source of this accumulation. The latest investigations have made it possible to find out that this phenomenon happened by the reiteration of certain events in the same place, specifically communal hunting episodes of these animals’ herds.

The hominids cooperation process was fundamental because they were coordinated to drive the bison to Dolina where they were trapped, killed and, afterwards, butchered for bring the meat, the bones and the skins to the campsite. The location of the camp site is still unknown, but probably, they should not far from the kill site.

concetracio-bisonts-dolina-p4
Bison bone bed at Gran Dolina (Atapuerca, Spain) – IPHES

This is confirmed in a just published paper in Journal of Human Evolution (JHE) whose main author is the archaeologist Dr. Antonio Rodríguez-Hidalgo, postdoctoral researcher at Universidad Complutense de Madrid and associated researcher in IPHES. “Until now it was thought that this behaviour was exclusive of anatomically modern humans, but we demonstrated that 400,000 years ago, it was fully developed. The pre-neanderthal from Sima de los Huesos (another archaeological site located a few meters from Gran Dolina), probable protagonist of this accumulation, they have the cognitive ability and the social development needed to applicate this type of hunting strategy”, claim Antonio Rodríguez-Hidalgo.

In words of Dr. John Speth, emeritus Professor of Anthropology in Ann Arbor University (in Michigan), this discovery can be considered one most important for Eurasia prehistory of the decade. “The communal hunting of big, nimble and potentially dangerous preys like bison implies that hunters were able to cooperate with each other and effectively coordinate their activities on a scale not previously demonstrated for pre-modern humans about 400,000 years ago”, he says.

In addition, the researcher adds: “the cooperative efforts to kill a multiple individual of an animal as large as the bison implies that the hunters may have shared flesh among the participants, again insinuating a level of social complexity that had not been previously demonstrated for such a remote period”.

All this has been known applying the zooarchaeology, an important tool for the subsistence reconstruction and to infer relevant aspects of social behaviour in the past. The taxonomic composition and the anatomical profile observed in approximately 23,000 bison bones (of a species yet to be identified, a close relative form of Bison priscus) extracted in the TD10.2 level of Gran Dolina indicates a monospecific assemblage strongly dominated by elements of the axial skeleton (heads, ribs and vertebrae).

According to realized studies it should be noted that the area of the archaeological site where the bison remains, may have been used as a kill site and first point of carcasses processing. The bones show a very skewed skeleton representation and at the same time uncommon in the prehistoric sites, considering that the axial elements dominate. “Due to  the large number of prey involved in each communal kill, the hominids could select the richest parts in meat and grease, such as limbs, and they bring it to the campsites, leaving the axial zone at the mercy of scavengers, wolves and hyenas”, observe Rodríguez-Hidalgo.

Hominids consumed the bison tongue as snack

“Together with these remains there was an unusual large number of hyoid bones (located under the tongue), some of them showing cut marks, which means that during the prey butchering, hominids consumed the bison tongue as snack for being rich in fat and protein discarding the hyoid bones at the site”, add the same researcher.

The abundance of anthropogenic modifications allows to observe primary and immediate access to the carcasses, as well as the development of a systematic butchering processed aimed at the exploitation of meat and fat, and the preparation for the transport of high utility elements to some place outside the cave (at the moment it is the assemblage with a greater number cut marks of the Palaeolithic record). “Ethnographic, ethnohistorical and archaeological analogies have made it possible to interpret the ‘bison bone bed’ as a kill site used during several seasonal communal hunting events in which whole bison herds were slaughtered to be intensely exploited by the hominids who occupied the cave”, specify Antonio Rodríguez-Hidalgo.

According to the same research, this hunting events was repeated seasonally, that is, in a timely manner at a few moments of the year. They used Dolina for bison capture and slaughter, late spring and early autumn, probably following the migrations of these animals.

“Through the study of eruption, replacement and dental wear pattern we have been able to infer that the TD10.2 bison died synchronously in two narrow seasonal windows, which together with the catastrophic mortality pattern that the population presents (that is, a decrease in the frequency of dead individuals as the age advances), support mass hunting or communal hunting as a predatory technique”, says the same IPHES archaeologist.

Antonio Rodríguez-Hidalgo added: “the communal hunting early existence as a depredatory tactic informs us about the cognitive, technological, and social skills emergence similar to those exhibited by other modern communal hunters at a time as early as the middle Pleistocene”. In addition, the archaeologist has specified: “a large number of coordinated individuals are needed and working cooperatively with the same objective to carry out this type of hunt, which until now was thought to be a modern human’s monopoly and perhaps the last Neanderthals”.

Gran Dolina site – IPHES

From the Dolina finding it has been shown that the action of those hominids was similar to the events that were generated about 10,000 years ago, in the Paleo-Indian groups in America. Likewise, there are several similarities between the communal hunting of bison used by the Native Americans in the Great Plains before the eighteenth century and the practices applied by the Gran Dolina hominids, who also had a high foresight capacity and knew the animals’ behaviour and the environment.

For these reason the events organisation could have been structured in a similar way since under these circumstances it was necessary for all members to take part in the process development, some as hunters and others as beaters. On the other hand, researchers have been able to document that there were other prey in the area to hunt, but the hominids deliberately decided to opt only for the bison and the communal hunting technique during a period that could last several generations.

An International team lead by IPHES discovered some of the earliest cultural evidences from modern humans out of Africa

These consist of a set of stone tools, dated up to 54,000 years, found in Kaldar Cave, Iran. This discovery has been recently published in Scientific Reports, one of the top-ten multidisciplinary science journals.

catalàespañolphotospaper

The recent research and archaeological excavation at Kaldar Cave (Iran), conducted by an Iranian and Spanish team and led by Behrouz Bazgir and Andreu Ollé, both from IPHES (Institut Català de Paleoecologia Humana i Evolució Social) have led to the identification of the first cultural evidences outside Africa attributed to Anatomically Modern Humans (AMH’s). The discovery consists of stone tools associated with faunal remains, recovered in a layer dated by Carbon 14 between 36,000 and 54,000 years ago. This discovery has been recently published in Scientific Reports, one of the top-ten multidisciplinary science journals.

Dating results of this archaeological site put Iran among the first birthplaces of modern humans that, along with Levantine hominin groups, for the first time managed to disperse from western Asia into Europe. In this way, Kaldar Cave strengthens Iran’s position in the world Palaeolithic archaeology.

Furthermore, the newly excavated sequence in Kaldar contains older levels with Mousterian industry, usually associated with Neanderthals. This provides evidence for its replacing by Baradostian industry, similar to the Aurignacian, which is unique to anatomically modern humans. Thus, this represents a unique opportunity to study the Middle to Upper Palaeolithic transition at the Zagros Mountains.

Kaldar Cave provides one of the oldest examples of modern human presence in this part of the world, and offers information on how these populations coped with the Palearctic climatic and environmental situations which were new to them.

19 international scientists have collaborated as co-authors in the article presenting these results. Among them, there are eminent specialists as Eudald Carbonell (IPHES and Universitat Rovira i Virgili, Spain), Jan van der Made (Museo Nacional de Ciencias Naturales, Madrid, Spain), Marcel Otte (University of Liège, Belgium) and Thomas Higham (University of Oxford, UK).The research counts also with Faranak Bahrololomi and Moloudsadat Azimi, collaborators from Research Center of Iranian Cultural Heritage, Handicrafts and Tourism Organization (RICHT), in the framework of an ongoing collaboration agreement signed with IPHES.
