Freshwater reservoir effects (FRE) can cause a major problem with radiocarbon dating human skeletal material in the Eurasian steppe. Recent research has demonstrated that, for the Eneolithic to Early Bronze Age sites of North-Eastern Kazakhstan, the maximum fish-herbivore freshwater reservoir offset observed equals 301±47 14C yrs, as such indicating that 14C dates from aquatic and human samples from the area apparently need to be interpreted with caution as they are likely to be affected by the offset. The current paper presents the new data on the FRE of the Eneolithic to the Early Iron Age sites of Kazakhstan and South of Siberia.

It is apparent from the widespread distribution of burnt mounds that Ireland was the most prolific user of pyrolithic technology in Bronze Age Europe. Even though burnt mounds are the most common prehistoric site type in Ireland, they have not received the same level of research as other prehistoric sites. This is primarily due to the paucity of artefact finds and the unspectacular nature of the archaeological remains, compounded by the absence of an appropriate research framework. Due to the widespread use of the technology and the various applications of hot water, narratives related to these sites have revolved around discussions of age and function. This has resulted in a generalised classification, where the term ‘fulacht fia’ covers several site types that have similar features but differing functions and age. The study presents a re-evaluation of fulachtaí fia in light of some 1000 sites excavated in Ireland. This is the most comprehensive study undertaken on the use of pyrolithic technology in prehistoric Ireland, dealing with different aspects of site function, chronology, social role and cultural context. A number of key areas have been identified in relation to our understanding of these sites. Previous investigations of burnt mounds have provided little information on the temporality of individual sites. It has been established that appropriate sampling strategies can provide important information about the formation of individual sites, their relationships to each other and to other monuments in the same cultural landscape. The evidence suggests that considerable caution should be exercised with regard to certain single radiometric dates from burnt stone deposits, based on the degree of certainty of the dated sample and its association with pyrolithic activity. Previously regarded as Bronze Age in date, there are now numerous examples of pyrolithic-type processes in earlier contexts, with the origins of the water-boiling phenomenon now considered to be Early Neolithic. A review of recent excavation evidence provides new insights into the use of pyrolithic technology for cooking. This is based on the discovery of faunal remains at several sites, combined with insights gained through experimental studies. The model proposed here is of open-air communal feasting and food sharing hosted by small family groups, as a medium for social bonding and the construction of community. It is also argued that if cooking was the primary activity taken place at these sites, this should not be viewed as a mundane functional activity, but rather one that actively contributed to the constitution of social relations. The formality of the technology is also supported by the presence of possible specialised structures, some of which were used for cooking/feasting while others were for ritualised sweat-bathing. The duration and frequency of activities associated with burnt mounds and the opportunities they provided for social interaction suggest that these sites contributed some familiar frames of reference to contemporary discourse.

Research in prehistoric sites of lakes and bogs around the Alps started more than 150 years ago. In 2004 Switzerland took the initiative to propose an international UNESCO world heritage nomination, which was successful in 2011. Six countries – Austria, France, Germany, Italy, Slovenia and Switzerland – joined forces to obtain the precious label for an invisible cultural heritage of outstanding universal value. Archaeological sites under water or in bogs are of special importance because objects made of organic material like wood, bark, plant fibres and others survive in this milieu for hundred or thousands of years. The alpine pile-dwelling sites offer a highly precise dating possibility by using dendrochronology. All in all these sites have a high scientific potential but run also risks of long term conservation. Beside the scientific chances there are risks to consider: public access is difficult and a major challenge. New ideas are demanded to keep alive public interest.

Ce mémoire traite de l’utilisation des matières premières lithiques telle que représentée sur les sites préhistoriques de la Moyenne-Côte-Nord du Golfe du Saint-Laurent, au Québec. Cette étude régionale se base sur la réanalyse d’un nombre important de collections archéologiques et accorde une grande importance à l’identification et à la description des matières premières utilisées. Un matériau d’origine locale, le Chert de la Minganie, y occupe une place particulière. L’importance de ce matériau pour la préhistoire régionale était jusqu’ici virtuellement inconnue. Suite à nos analyses, un inventaire complet des matières premières utilisées est mis sur pied. Ces données mettent en évidence un certain nombre de comportements. Principalement, nous identifions deux ensembles qui illustrent la présence de territoires attribuables à la répartition de groupes amérindiens subrégionaux (bandes). Finalement, à travers l’utilisation des ressources lithiques, les liens qui rattachent les groupes de notre région d’étude à ceux de la péninsule du Québec-Labrador sont illustrés.

This paper considers the dynamics of deposition around and across the causewayed enclosure at Etton, Cambridgeshire. As a result of detailed re-analysis (particularly refitting) of the pottery and flint assemblages from the site, it proved possible to shed new light both on the temporality of occupation and the character of deposition there. Certain aspects of our work challenge previous interpretations of the site, and of causewayed enclosures in general; but, just as importantly, others confirm materially what has previously been suggested. The quantities of material deposited at Etton reveal that the enclosure was occupied only very intermittently and certainly less regularly than other contemporary sites in the region. The spatial distribution of material suggests that the enclosure ditch lay open for the entirety of the monument's life, but that acts of deposition generally focused on a specific part of the monument at any one time. As well as enhancing our knowledge of one particular causewayed enclosure, it is hoped that this paper – in combination with our earlier analysis of the pit site at Kilverstone – makes clear the potential that detailed material analysis has to offer in relation to our understanding of the temporality of occupation on prehistoric sites in general.

First indications of prehistoric sites in lakes of Switzerland go back more than 200 years and in 1854 Ferdinand Keller (1800-1881) published his famous book The Celtic Pile Dwellings in Swiss Lakes. Since these times, large-scale rescue excavations as well as survey and research projects have extended our knowledge about Neolithic and Bronze Age settlements in lakes, bogs and rivers around the European Alps. In 2011 a representative choice of 111 sites out of nearly 1000 in six countries around the Alps (Austria, France, Germany, Italy, Slovenia and Switzerland) were recognized by the UNESCO World Heritage committee as serial World Heritage. The lecture will give a general overview on prehistoric lake dwellings around the Alps (distribution, types of lakes/bogs and environment of sites, chronology/cultural units in the time scale 5300 to 800 BC) and present examples of well-documented settlement structures. The intense use of dendrochronological dating allowed the building up of a well-fixed chronological framework. In some cases dendrochronology is the basis for year-by-year reconstructions of prehistoric village biographies and detailed insights in the life cycle of early agrarian settlements. Beside these local events the grouped repartition of lake dwelling remains on the time scale makes a more global correlation between Holocene lake levels and the preservation of archaeological layers likely.

Evidence for osseous technologies has featured in excavation reports from Southeast Asia for almost a century and from archaeological deposits as old as 43,000 years BP. However, in contrast to the significance that is placed on this technology in other parts of the world, until recently, Southeast Asian assemblages have drawn only very limited attention. Concentrating on evidence from Malaysia, the current paper examines one element of this inventory of tools: the deliberate modification of pig canines and the means by which such alteration can be distinguished from patterns of natural tooth wear. Particular attention is paid to the bearded pig (Sus barbatus), as it is one of the two species of wild boar in Malaysia whose tusks are most likely to have been used by prehistoric toolmakers. Reference is also made to wider, regional ethnographic examples of known tusk implements and their accredited uses to further assist in the identification process. Distinguishing criteria for worked tusk are formulated according to the type and extent of modification. These criteria are then applied to archaeological specimens recovered from two prehistoric cave sites in Malaysia, Gua Bintong and Niah Cave.
