A new approach to study the fuel used in hearths by hunter-gatherers at the Upper Palaeolithic site of Abri Pataud (Dordogne,France)

The fuel used in hearths in the Upper Palaeolithic period and the management of this fuel have long given rise to questions on intentional or opportunistic human comportment. To understand how fuel was managed during the Aurignacian and Gravettian cultures, hearth samples from the French site of Abri Pataud (ca. 34–20 kyr BP) were collected. An image analysis method for the automated quantification of burnt particles from macroscopic-to-microscopic sediment fractions was developed, and the results obtained using this method were compared with the palaeoenvironmental data available close to the site. At Abri Pataud, the use of bones was dominant during the Pleniglacial, suggesting an intentional practice. However, environmental pressures could have influenced the fuel management practices of the hunter-gatherers, even if the dualistic relationship between the availability of firewood and the use of bone in hearths must be considered. Thus, burnt particle quantification provides more than just an observation of burnt macroremains in hearths: it relates to fundamental information on human behavior.     

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.     

Cesium magnetometer surveys at a Pithouse Site near Silver City,New Mexico

The La Gila Encantada Site is located on an isolated ridge top north of Silver City, New Mexico in an area defined culturally as the Mimbres Mogollon region. The 180 m × 80 m (14400 m²) sized site was originally recorded as a dense scatter of ceramics, lithics, and ground stone along with a number of surface depressions that appear to represent pithouses. Cesium magnetometer surveys were conducted to identify hearths, pithouse boundaries, and activity areas outside of pithouses in support of archaeological investigations, and to test this instrument's ability to image these features. This paper presents a characterization of the magnetic signature of a pithouse as a magnetic high in the center caused by the central hearth, low magnetic variability along the floor of the house, and then increased magnetic variability at the pithouse boundary. This characterization was successfully confirmed for three pithouses using cesium magnetometery and archaeological excavation.     

New dates from Ushki-1, Kamchatka,confirm 13,000 cal BP age for earliest Paleolithic occupation

For many years cultural layer 7 at the Ushki sites, Kamchatka was considered to represent the earliest human occupation of Beringia, because four radiocarbon dates indicated an age of 16,000–17,000 calendar years ago (cal BP). In 2003, however, Goebel et al. reported that layer 7 more likely formed only 13,000 cal BP, nearly 4000 years later than N.N. Dikov, the site’s primary excavator, originally reported. Some researchers have downplayed the significance of the new dates, continuing to regard Dikov’s early dates as evidence that at least some of the hearth and dwelling features previously excavated at Ushki-1 date to as early as 17,000 cal BP. Here we present four new radiocarbon dates (and two previously unpublished dates) on curated charcoal from hearth features excavated at Ushki-1 more than 20 years ago. They indicate that these hearths and associated dwelling features date to about 13,000 cal BP. We now know 15 radiocarbon dates on charcoal from a variety of features and profiles across Ushki-1 and Ushki-5 that indicate the age of layer 7 is about 13,000 cal BP. We discount the four 16,000–17,000 cal BP dates, first, because two of them came from a deeply dug human burial pit and were likely secondarily introduced into the burial; second, because provenience data for the other two dated samples were never reported and do not exist in the records of the radiocarbon laboratories that produced them; and, third, because sediments immediately underlying layer 7 at Ushki-1 are only a few centuries earlier than 13,000 cal BP, providing an important lower-limiting age for the layer-7 occupation. We conclude that the age of all of the layer-7 features at Ushki-1 and Ushki-5 should be considered to be about 13,000 cal BP, at least until the earlier obtained old dates of 16,000–17,000 cal BP can be replicated.     

A new calibration of the XRD technique for the study of archaeological burned human remains

A new calibration of human bones as a function of programmed temperature (200–1000 °C) and time (0, 18 and 60 min) is presented and discussed in order to investigate the issues related to the study of cremated bone remains by using the powder X-ray diffraction approach. The experimental results confirm the growth of hydroxylapatite crystallites as a function of the applied temperature, with a sigmoid behaviour that has been parameterized to the experimental data points. Particularly, it was observed that the thermal treatments for 60 min anticipate of about 100 °C the effects that are otherwise observed after the treatments for 0 min. The developed procedure was subsequently applied to cremated remains of various archaeological sites of Spain and supplied precise information not only about the temperature reached during the funerary rites, but also on the presumed duration for the cremation.     

Is vitrification in charcoal a result of high temperature burning of wood?

The term ‘vitrified’ is used to describe the glassy appearance of some charcoals recovered in the archaeological record. It has been generally considered that this phenomenon is a result of wood being subjected to high temperatures similar to the role of temperature in the formation of glass and pottery. Charcoals displaying characteristics of vitrification from three distinct archaeological contexts were analysed using reflectance microscopy to determine their temperature of formation. Charcoal was also generated in laboratory charring experiments at temperatures of 900–1100 °C for durations of 1, 6, 12 and 24 h to determine if subjection to high temperature led to vitrification. None of the laboratory-produced charcoals displayed characteristics of vitrification. Mean random reflectance of the vitrified archaeological fragments indicated temperature of formation from 310 to 530 °C. A charring experiment was also conducted, at 500 °C for 6 h, using green wood with some bark attached, and added sugars, but no evidence of vitrification was seen. Therefore vitrified charcoals do not result from high temperature charring or primarily from the use of green wood.     

Going underground: experimental carbonization of fruiting structures under hearths

We show that carbonized fruits and seeds recovered from Middle Stone Age deposits in rock shelters are likely to have been carbonized as part of post-depositional processes. We buried indigenous South African fruits, nuts and seeds at pre-determined depths and distances from the centers of experimental fires. The cold ashes of the hearths and the sand surrounding them were subsequently excavated, using standard archaeological techniques and dry-screening. The fruiting structures from the oxidizing part of the fire were burnt to ashes, whereas those buried in sand under anoxic conditions survived in varying forms. Those buried 5 cm below the center of the fire were carbonized; those buried 10 cm below the center of the fire were dehydrated; and those 5 cm and 10 cm below the surface at the outer edge of the fire were unaffected. Size, moisture or oil content of the original fruit or seed did not appear to influence whether or not carbonization took place. Temperatures recorded 5 cm below the experimental fires suggest that the carbonization occurred at or before a maximum temperature of 328 °C, and also at lower maximum temperatures (152 °C) that were maintained for long periods. Even when the quantities of a particular wood are controlled, open fires may produce variable underground temperatures and the temperatures below ancient hearths would have been equally variable. We suggest that Cyperaceae (sedge) nutlets, the most numerous fruiting structures in the Sibudu Middle Stone Age archaeobotanical assemblage, occur in the shelter as a result of human activity, subsequent burial, and accidental carbonization when hearths were built directly above the buried nutlets.     

The social role of food in the Natufian cemetery of Raqefet Cave,Mount Carmel,Israel

The archaeology of mortuary practices and related foodways in the Late Natufian (LN; ca. 14,000/13,500–11,700 BP) sheds light on the communal activities of the last hunter–gatherers in the Mediterranean Levant. We present a detailed analysis of the fauna from the LN cemetery of Raqefet Cave (Mount Carmel, Israel). Taphonomic evidence indicates that the animal bones are butchery and consumption leftovers. While the patterns of animal exploitation are reminiscent of Natufian habitation sites, the remains do not reflect the typical recurring post-discard damage resulting from continuous or repeating habitations in those sites. Hence the fauna is interpreted as the leftovers of punctuated, short-term events, rather than ‘ordinary’ Natufian household trash. Taking into account the special depositional context and site characteristics, we interpret the fauna as the intentionally-gathered and buried remains of simple funerary feasts. Elaborate mortuary behavior and symbolic role of food refuse were recently suggested at the contemporaneous cave of Hilazon Tachtit (Israel). The new data from Raqefet Cave probably reflect a somewhat different type of communal meals, adding to the diversity and complexity of pre-agricultural life-ways in the Levant.     

Radiologic proof for the Iceman's cause of death (ca. 5’300 BP)

A possible cause of death of the Iceman – a ca. 5’300 BP natural human glacier mummy from the Tyrolean Alps – is an intrathoracic stone arrowhead. The aim of this study was to prove radiologically his enigmatic cause of death. In August 2005, the Iceman underwent his first multislice computed tomography examination. As the main pathologic finding, the left dorsal subclavian artery contures shows a 13 mm-long part where the vessel wall is damaged and a 3 mm-long irregular pseudo-aneurysm – a typical complication of a laceration of the subclavian artery. In the surrounding soft tissue a large haematoma is visible. Historic records highlight the fatal destiny of subclavian artery injuries e.g. due to massive active bleeding and shock-related cardiac arrest. Therefore, the Iceman's cause of death by an arrowhead lacerating among others the left subclavian artery and leading to a deadly hemorrhagic shock can be now postulated with almost complete certainty, especially when taking the environmental (3’210 meters above sea level) and historic (5’300 BP) settings into account.     

The Golden Code of the Bird‐Men: Iconographic and Social Interpretation of the Moñes I Diadem‐Belt (Asturias,North‐west Iberian Peninsula,First Century BC)

If there is one piece of the Castro culture goldwork that stands out above the rest, it is the set of figurative gold diadem‐belt fragments from Moñes (Piloña, Asturias, Spain). Its uniqueness lies in its combination of local technological tradition with exogenous practices, like figurative representation. The figures that appear are armed characters, occasionally on horseback, and sometimes zoomorphic in appearance (especially as bird‐men), together with different kinds of animals, especially those from an aquatic environment. This iconography has been interpreted as emphasizing the warlike character of Celtic symbolism as expressed through an aquatic funerary ritual. My argument here, however, provides an alternative interpretation based on a context of dramatic social change, which warranted the reformulation of creation mythology such as that depicted on the diadem‐belt. This context must be viewed in relation to different social responses which developed during the first century BC, both before and immediately after the Roman conquest.     

A study by thermal treatment and X-ray powder diffraction on burnt fragmented bones from tombs II,IV and IX belonging to the hypogeic necropolis of “Sa Figu” near Ittiri,Sassari (Sardinia,Italy)

In the course of an anthropological investigation of three tombs of the hypogeic necropolis of “Sa Figu” (near the village of Ittiri in North Sardinia, Italy), numerous burnt bone fragments were collected. In particular, from the whole necropolis we selected a tenth of long bones from tomb IV, a small fragment of femur from tomb II and four fragments belonging to tomb IX. The aim of this work is to determine a temperature range to which the bone fragments were heated, in order to assess a funerary cremation which was presumably used at that time to quickly and hygienically eliminate the flashy parts of deceased people rather than a purification rite with fires inside the sepulchres. We attempted to evaluate the range of temperature to which the bones were likely subjected, making a joint use of thermal treatment and powder X-ray diffraction investigations. From our X-ray line broadening results carried out with a modern approach (Rietveld method), it emerged that a group of five fragmented burnt bones (one specimen belonging to tomb IV, the other four from tomb IX) were subjected to a heat treatment in a temperature range from 600 and 750 °C. Conversely another group of bones (belonging to tombs II and IV) turned out to be subjected to temperatures not higher than 250 °C.     

Charcoal analysis and dendrology: data from archaeological sites in north-western France

During the last 15 years, charcoal analysis of archaeological sites in north-western France has been carried out in conjunction with systematic and detailed dendrological examination. By considering these extrinsic criteria in association with the analytical results, palaeo-ethnographic and palaeo-environmental information can be obtained. The charcoals are classically identified under the microscope on the basis of their cellular structure. This examination is associated with an observation of the ligneous structure on transverse sections using a binocular lens. When charcoal fragments are large enough, the growth ring widths are measured. Tree ring curvature is also noted. Finally, alteration by fusion or radial cracks, the presence of fungal hyphae, and insect degradation are also recorded. Results are thus obtained on the nature of fuel used in domestic fireplaces and kilns. The selection of timbers and their catchment areas are also revealed. The average width of the growth rings in oak charcoal from domestic hearths coming from about forty sites in north-western France shows a significant increase from 6000 to 2000 BP. There is a similar increase in the number of heliophilic taxa used from the Neolithic to the Iron Age. This implies that the environment became more and more open because of use by society. The interpretation of the dendrology results applied to charcoal analyses is obtained through a convergence of criteria. Thus, charcoal analysis can provide more than just an identification of the species used, and can yield fundamental information on the interaction of society with the environment.     

Hafted armatures and multi-component tool design at the Micoquian site of Inden-Altdorf,Germany

Excavation of the Micoquian site Inden-Altdorf (Weisweiler-124) near the former German capital Bonn in western Germany has revealed the first valid open-site habitation features with hut-like structures and associated hearths for the Middle Palaeolithic in Central Europe. It has been dated to the Eemian interglacial (OIS 5e), a warm interglacial between 128 and 115 ka BP. Various wear traces and especially organic residues have been detected on a large number of stone tools using microscopic use-wear analysis of lithics recovered from the site. A multi-level analysis developed through an experimental framework and archaeological study using optical light microscopes, scanning electron microscopes and energy-dispersive X-ray microprobes identified the adhering residues as birch pitch. Birch pitch is the oldest synthetically produced material and was used as an adhesive to attach lithic implements to wooden shafts. While such hafting technology is commonly associated with modern humans in the Upper Palaeolithic, the birch pitch residues found on the Micoquian tools of Inden-Altdorf suggest that hafting technologies and the frequent use of multi-component tools already existed in the Middle Palaeolithic, c. 120 ka BP in central Europe.     

Human soft tissue preservation in the Cova des Pas site (Minorca Bronze Age)

The preservation process of soft tissues in an archeological context is mainly unknown because they occur only in truly exceptional situations. The Cova des Pas is a Bronze Age site in Minorca where the special conditions enabled the preservation of some soft tissues associated with 66 individuals. This finding allows the study of the preservation process that took place by means of the analysis of the histological and chemical characteristics of the tissues. Our results show that the preservation mechanism was the adipocere, because the fatty acids profile shows higher concentration of saturated than unsaturated fatty acids. The evidence indicates that the kind of funerary ritual and the environmental conditions favored this preservation.     

Early Neolithic funerary diversity and mitochondrial variability of two Iberian sites

An analysis of the burial characteristics of the individuals recovered from two Early Neolithic sites in Navarre (Los Cascajos and Paternanbidea), in the Spanish Basque Country, revealed a complex funerary ritual. The individuals recovered from the Paternanbidea site were distributed in three double graves and a multiple one, while the individuals from Los Cascajos were buried in individual pit-shaped tombs; furthermore, the tombs had a variety of cultural and funerary features. The aim of this study is to evaluate the burial ritual by means of mitochondrial DNA data and the funerary characteristics of 36 individuals recovered from these two sites. The results show that the diversity of these Early Neolithic burial practices from the northern Iberian Peninsula cannot be explained by means of maternal kinship relationships.     

The technology Of the yamnaya (pit grave) ceramic production And its relevance to the population history Of the volga-ural region in the early bronze age

Based on ceramic assemblages from the Yamnaya (Pit Grave) culture burials, the technology of pottery manufacture practiced by the Early Bronze Age people of the Middle Volga–Southern Ural region is described. The analysis follows the methodology developed by A.A. Bobrinsky. The results are used for reconstructing the origin and evolution of the Pit Grave culture. The role of ceramics in Early Bronze Age funerary ritualism is discussed.     

Roman blue-green bottle glass: chemical–optical analysis and high temperature viscosity modelling

Chemical analysis, optical absorption spectroscopy and mathematical modelling of high temperature viscosity have been carried out on five 1st–2nd century AD Roman blue-green bottle glass fragments from Coppergate, York. Modelled viscosities indicate remarkable consistency within the sample set studied and support the suggestion that temperatures of ∼1000–1150 °C were required to remelt these glasses and to provide suitable viscosities for forming articles. Iron redox ratios (Fe²⁺/ΣFe), analysed SO₃ contents and the absence of characteristic Fe³⁺–S²⁻ amber absorption bands suggest that melting conditions for all studied glasses were mildly, rather than strongly, reducing (estimated pO₂ ≈ 10⁻¹–10⁻⁶ bar). These furnace conditions are consistent with the effects of combustion gases and carbonaceous matter contained in the raw materials.     

Material evidence for the use of Attic white-ground lekythoi ceramics in cremation burials

White-ground lekythoi ceramics offer important evidence for funeral practices in Ancient Greece (5th century BC). The images painted-on these oil containers provide the best visual narrative for the events surrounding death, including indications that the vessels themselves were used as part of the funerary rites. However, until now, their specific function and treatment within the funeral ceremony was not well understood. We present here material evidence that the vessels were ritually burned, together with the body of the deceased, during cremation, as evidenced by a diffuse purplish-red discolouration found on many white-ground lekythoi. Through EPMA and μXAS studies, we show that: (1) this characteristic purplish-red discolouration is due to the presence of metallic copper nano-particles embedded in a glassy layer; (2) this metal-glass matrix formed as the result of a high temperature reaction between painted-on Cu-based pigments (e.g., Egyptian blue) and the white-ground ceramic slip; and (3) the reaction occurred under a reducing environment. Given the mortuary context for these vessels, we propose the reduction firing to which the vessels were exposed was that associated with the cremation of the body. The observation of discontinuous formation of the purplish-red discolouration along adjoining fragments supports the hypothesis that the vessels were broken prior to being burned. The majority of lekythoi in museum collections lack information on their original archaeological context, and our data suggest the presence of this purplish-red discolouration may serve as a visual marker for cremation. As such, it is expected our findings will provide a new basis for interpreting how this important class of ceramic, and associated iconographic imagery, relates to Athenian funerary practices and the ancient Greek notion of death.     

The Nature and Function of Astragalus Bones from Archaeological Contexts in the Levant and Eastern Mediterranean

Worked and unworked astragalus bones from a variety of different animals have been excavated throughout the eastern Mediterranean and Near East in several different contexts. This paper examines the nature and function of astragali and their modifications, and concludes that they were most often used as gamepieces, but also served a ritual function in cultic and funerary contexts. The frequent use of astragali in ritual contexts is due to the manner in which animals were skinned, and as a result of cultural diffusion. The frequent occurrence of worked astragali in cultic and funerary contexts allows them to serve as potential indicators of ritual activity in archaeological excavations.     

Stone statue of Ailyan,Gorny Altai

A rare stone statue found in Gorny Altai and associated with the Ancient Turkic culture is described. Most Ancient Turkic statues in the Sayan-Altai and in Central Asia in general represent male warriors. This statue, however, depicts a female. Research is relevant to the understanding of Eastern Turkic funerary ritual.
