Evidence for the trade of Mesopotamian and Egyptian glass to Mycenaean Greece

The origins of raw glass used to fashion Mycenaean beads were explored using trace elements analyzed by laser ablation ICP-TOFMS. The use of this minimally destructive technique for the in-situ analysis of these beads was ideal given that the material is exceedingly rare and thus too sensitive to make use of traditional micro-sampling (e.g., by scalpel). A wide range of trace elements were measured to compare these Greek glasses to other Late Bronze Age glass coming from Egypt and Mesopotamia. Of the eleven beads analyzed, four blue glasses colored with cobalt and two blue/green glasses colored with copper have trace element compositions consistent with an Egyptian origin of manufacture. The other five of the glasses, all colored with copper, were found to conform to the composition of Mesopotamian glass. These data are the first to demonstrate direct and clear evidence for the trade of raw glass to the Mycenaean states.     

Probable evidences of bone accumulation by Pleistocene bearded vulture at the archaeological site of El Mirón Cave (Spain)

The bearded vulture (Gypaetus barbatus), a bird or prey that mainly feeds on bones of large mammal carcasses, has been recently evidenced as an accumulating agent with significant contributions to palaeontological assemblages in caves and shelters, but extremely rare at archaeological sites. The results of the taphonomic analyses carried out in the Upper Palaeolithic layers of El Mirón Cave (Cantabrian Spain), which are presented here, evidence the existence of special digestive marks and a typical skeletal pattern in a noticeable amount of small and medium-sized ungulates bones. This fact suggest that a representative part of the bone assemblage has been caused by bearded vultures, and strengthens the idea that this bird has to be definitely included among other potential non-human accumulators in archaeological sites.     

Remodeled human skulls in Köşk Höyük (Neolithic age,Anatolia): a new appraisal in view of recent discoveries

Between 1985 and 2007 overall nineteen human skulls dating to the Late Neolithic period were recovered at Kö?k Höyük, which lies within the borders of Bor, a district of the Ni?de Province in Central Anatolia. One of these skulls belongs to a child and the remainder to adult males and females. The plastered skulls may have been laid on or wrapped in mats and exposed either singly or in groups on a plaster surface inside the house. Among thirteen of these skulls the mouths, noses, eyes and ears were depicted with clay and painted with red ochre, while the remaining six were untreated. Two headless skeletons were also found in situ underneath the floor inside the house. One of these skeletons belongs to a child aged approximately 15–16 years old and the other belongs to an adult female. The modeled human skulls were encountered in the second and third cultural levels of the Late Neolithic period indicating that this characteristic mortuary practice lasted for quite a long time and likely disappeared by the Chalcolithic at Kö?k Höyük.     

Testing the ‘Laacher See hypothesis’: tephra as dental abrasive

In a series of recent studies, changes in material culture and settlement pattern in the Late Glacial of Northern Europe have been linked to the eruption of the Laacher See volcano. This eruption occurred c. 13,000 years ago towards the end of the Allerød chronozone. It is argued that the tephra fall-out from this eruption set in motion significant demographic fluctuations along the northern periphery of Late Glacial human settlement and that these led to a number of material culture transformations. In particular, the emergence of the regionally distinct techno-complexes with large tanged points – the Bromme culture in southern Scandinavia and the Perstunian culture in northeastern Europe – and the temporary abandonment of central European regions are thought to relate to this eruption. While numerous archaeological datasets are in accord with this ‘Laacher See hypothesis’, the forcing mechanism or mechanisms that brought about these archaeologically visible changes have remained largely unexplored. A particular challenge is to explain how some of the culture-historical effects of the Laacher See eruption seem to change or become more pronounced with distance from the eruptive centre. We here investigate one potential middle-range link between the Laacher See eruption and Late Glacial fauna and foragers: tephra as dental abrasive. We use instrumented nanoindentation to quantitatively investigate tephra from a number of sites covering the medial and distal fall-out zones as well as the dental enamel of Homo sapiens and key prey species of Late Glacial foragers. Our results show that the Laacher See tephra contained particles roughly twice as hard as even the hardest portions of any of the teeth investigated. We also suggest that fluoride-induced weakening of dental enamel may have further aggravated tooth wear. These mechanisms may have acted in concert to produce elevated levels of, in particular, animal mortality, which in turn may have led to an abandonment of the affected landscapes.     

Radiocarbon dating of marine shell samples. The marine radiocarbon reservoir effect of coastal waters off Atlantic Iberia during Late Neolithic and Chalcolithic Periods

Radiocarbon dates on marine shells have not been used as extensively as charcoal or bone dates for the setting up of absolute chronologies because interpreting these dates is complicated by the marine radiocarbon reservoir effect. Nevertheless marine shellfish were used widely at least during the Holocene and their shells are abundant and usually well preserved in archaeological deposits located near shorelines. Consequently prior research concerning the oceanographic conditions and the marine radiocarbon reservoir effect of a particular coastal area is needed in order to set up reliable chronologies for that region. Values of regional marine radiocarbon reservoir effect – ΔR – of coastal waters off Atlantic Iberia, some of its variability along the Holocene and its correlation with the upwelling phenomenon were determined during previous research. More data related to the ΔR values for western Portuguese coastal waters during the Late Neolithic and the Chalcolithic, a time interval badly sampled in previous research, were recently obtained. These values can be compared with ΔR values already determined for the Gulf of Cadiz. Besides the importance of these values for a better knowledge of the palaeoceanography and palaeoclimatology of Atlantic Iberia, from now on archaeologists can set up reliable chronologies for Late Neolithic and Chalcolithic contexts using marine shell samples of that origin for radiocarbon dating.     

Human corpse manipulation and the body as symbol: A case study from the Eastern Pampa–Patagonia transition (Argentina) during the Final Late Holocene

Human body manipulation and secondary burials are widespread funerary practices in many areas of the world. The archaeology of the Pampas and North-Eastern Patagonia, Argentina, is no exception. In this paper, archaeological case studies from the lower basin of the Colorado River during the Final Late Holocene (ca. 1000–250 years BP) are presented and discussed. Secondary burials were recovered that indicated an intentional manipulation of bodies. Evidences of cut marks and the coloring of bone surfaces were recorded. The bundles were composed of individuals of both sexes and diverse age categories. The Pampean region and North-Eastern Patagonia witnessed significant hunter–gatherer population dynamics during the last 1000 years BP. Climatic, ecologic, demographic, and economic explanations have been proposed as the background to these changes. In this paper, it is argued that accompanying these factors, as part of a broader socio-cultural scenario, were significant social interaction networks and processes of social complementarity between groups. In this context, it is proposed that the complexity observed in relation to the handling of bodies is part of a worldview in which the body was seen as material culture – as a symbol – that played an important role for the community in group identity maintenance in a cultural context undergoing significant organizational changes.     

Opacifiers in Late Bronze Age glasses: the use of ToF-SIMS to identify raw ingredients and production techniques

Time of Flight Secondary Ion Mass Spectrometry (ToF-SIMS) is applied to the study of four samples of opaque glass of Late Bronze Age date. The technique is uniquely capable of identifying compositional heterogeneity at a sub-micron resolution within the crystalline opacifiers dispersed through homogeneous glass matrices. It is shown that this provides crucial information on the possible raw ingredients of the opacifying inclusions used, and has the potential for highlighting regional variations in the production technology involved in creating different colours of opaque glass.     

Pre-Clovis in Texas? A critical assessment of the “Buttermilk Creek Complex”

Lithic artifacts from the lowest strata of the Debra L. Friedkin site, located on Buttermilk Creek in central Texas, have been interpreted as an undisturbed pre-Clovis assemblage (Waters et al., 2011a). Stone tools and debitage were recovered from sediments stratified just below diagnostic Clovis artifacts and dated by OSL to between 13.2 and >15.5 cal kya. Invoking commonly observed cultural and natural site formation processes, we offer an alternative explanation of the “Buttermilk Creek Complex” as a Clovis assemblage in secondary association with the dated sediments.     

Temporal nature and recycling of Upper Paleolithic artifacts: the burned tools from the Molí del Salt site (Vimbodí i Poblet,northeastern Spain)

Recent research in Paleolithic archeology has stressed the importance of temporal issues in assemblage interpretation. Archeological assemblages are temporal constructs, formed by the addition of an unknown number of depositional events. This temporal dimension is also evident at the artifactual level, since single artifacts may undergo different events of modification and/or uses over time. The recycling of previously discarded blanks for tool production is one of the best examples of the temporal nature of artifacts. The aim of this paper is to evaluate the importance of recycling in a Late Upper Paleolithic site, examining a type of artifact – burned tools – that has up to now been little used to approach this issue. Our results suggest that recycling was probably a significant component of Upper Paleolithic provisioning behavior, with important implications in site formation processes and the typological variability of assemblages. The expedient or curated character of recycling is also discussed.     

Petrography as a technique for investigating Iroquoian ceramic production and smoking rituals

Petrographic data and macroscopic observations are used to examine some of the social contexts and functional considerations underlying the production of pottery containers and smoking pipes at Antrex, a Middle Ontario Iroquoian village site located in southern Ontario. Results suggest that while pottery was produced by small groups of people for widespread consumption within the community, pipes were made by individuals for their own personal use. Overall, this research supports the hypothesis that by the beginning of the Late Woodland period, a shift away from communal ritual practices led by ritual specialists or shamans had occurred. Smoking might have, in some contexts, become a solitary religious experience.
