Raw material quality and Oldowan hominin toolstone preferences: evidence from Kanjera South,Kenya

The role of raw material quality in Oldowan technology has not been fully explored. There are numerous studies suggesting Oldowan hominins preferred certain types of stone for artifact manufacture. Previous studies of the artifact assemblage from the early Pliocene Oldowan locality of Kanjera South (South Rachuonyo District, Kenya) show that raw material selection and transport was an important aspect of Late Pliocene hominin adaptations. Yet the exact properties of stones that hominins were selecting remain enigmatic. Two potentially important features of artifact raw material are durability and fracture predictability. We investigate fracture predictability through mechanical tests of stone and investigations of the affect of stone properties on fracture patterns in archaeological collections. We investigate stone durability with actualistic studies of edge attrition combined with further mechanical tests of various lithologies. Oldowan hominins at Kanjera appear to have selected raw materials based on their durability. The ability for a stone to fracture consistently does not appear to be as important in hominin toolstone preference as previously assumed. Hominins that produced the assemblages at Kanjera South appear to have incorporated an extensive understanding of various attributes of raw material in the transport and production of stone artifacts. When combined with previous research on the transport patterns at Kanjera, the results of this study provide evidence for a more complex raw material acquisition strategy than has previously been suggested for Late Pliocene Oldowan hominins.     

Heat Treatment of Mineral Pigment During the Upper Palaeolithic in North‐East Italy

The use of red ochre for utilitarian, symbolic and artistic purposes is widely documented in prehistoric contexts. The absence of adequate red‐coloured raw materials influenced the development of technological activities aimed at modifying the original physiochemical properties of yellow ochre. The heat treatment of goethite to obtain hematite was investigated in the western sector of the Lessini Mountains in north‐east Italy, where red ochre was found in the (Proto)Aurignacian levels at Fumane cave and in the Late Epigravettian sequence at Tagliente rockshelter. The combination of X‐ray powder diffraction (XRPD) and transmission electron microscopy (TEM) proved that heat treatment was a common practice in the studied archaeological sites due to the scarce availability of suitable hematite‐based material in the region.     

First Insights into the Technique Used for Heat Treatment of Chert at the Solutrean Site of Laugerie‐Haute,France

The earliest evidence of flint and chert heat treatment was found in the ~21.5–17 ka old European Solutrean culture. The appearance of pyrotechnology as part of the production of stone tools has important implications for our understanding of Upper Palaeolithic technological evolution and the specific adaptations during the last glacial maximum in Europe. However, the techniques and procedures used to heat‐treat rocks during the Solutrean remain poorly understood. No direct archaeological evidence has so far been found and the most promising approach is to understand these techniques by determining the parameters with which flint and chert were heated at that time. In this study, we investigate the heating temperature of 44 heat‐treated laurel‐leaf points from Laugerie‐Haute, using a non‐destructive technique based on infrared spectroscopy. Our results document that most of the artefacts were heated to a narrow interval of temperatures between 250 °C and 300 °C. This indicates a standardized technique that allowed to created similar conditions during successive heating cycles. The implications of these results for our understanding of the technical complexity during the Solutrean must be discussed in the light of different heating techniques used at different places and periods.

Did Modern Human Dispersal Take a Coastal Route into India? New Evidence from Palaeolithic Surveys of Kachchh,Gujarat

The Indian Ocean coastline is argued to have been a critical route of modern human dispersal from Africa, introducing Late Palaeolithic industries into South Asia, but a dearth of evidence has prevented a direct evaluation of this. Kachchh (Gujarat, India), located immediately east of the Indus Delta, is an important setting to appraise the Palaeolithic occupation of the western Indian coastline. Targeted survey of Late Pleistocene sediments there found widespread evidence for occupation of Kachchh during the Late Pleistocene: Middle Palaeolithic and possibly Late Acheulean lithic artifacts. The conspicuous absence of Late Palaeolithic industries in these Late Pleistocene deposits, with their presence only noted in Holocene contexts, does not support the model of modern human expansions into India with these industries via the coastal route. We evaluate these results in the context of current debates regarding Late Pleistocene hominin demography, adaptation, and expansions.     

The ESR geochronology and geology of the open‐air Palaeolithic deposits in Bollschweil,Germany*

This paper presents ESR (electron spin resonance) ages of rhinoceros and equine tooth enamel from the open‐air Palaeolithic site of Bollschweil on the western edge of the Black Forest near Freiburg, Germany. Bollschweil is one of very few archaeological sites in southern Germany to yield Lower or Middle Palaeolithic faunal and lithic materials from a buried, open‐air context. The geological context of the archaeological remains indicates that the loessic sediments have been reworked. Excavation at this site yielded a cold‐period fauna characterized by bones of mammoth, horse, large bovids and wooly rhinoceros. In the absence of any clear chronostratigraphic marker horizons, the age of the finds could not be determined without the use of a chronometric dating method. Lithic artefacts from the site, including a handaxe and a side scraper, suggest either a Middle Pleistocene or early Late Pleistocene age. The ESR dating results indicate that the deposit enclosing the archaeological finds should be assigned to oxygen isotope stage (OIS) 6, although there exists some possibility that some teeth were deposited later, in OIS 5.     

The Shuidonggou site complex: new excavations and implications for the earliest Late Paleolithic in North China

The initial Late Paleolithic, said to appear between 40 and 30 kya in eastern Asia, is defined by the appearance of many innovations. These archaeological indicators include the appearance of more refined stone tool making techniques (e.g., include the appearance of blade and microblade technology), complex hearth construction, use of pigments and personal ornamentation, as well as worked faunal implements such as bone and antler tools. We report here new findings from a multidisciplinary research project conducted at the Shuidonggou (Choei-tong-keou) site complex in northern China, a series of localities that date from the initial Late Paleolithic to the Neolithic.     

A tale of two sites: Functional site differentiation and lithic technology during the Late Pithouse period in the Mimbres area of Southwestern New Mexico

The raw materials from which stone tools are made can provide considerable information relevant to behavioral variation within a prehistoric population. By examining the stone used for tools from two different types of Late Pithouse period (A.D. 550-1000) residential sites from the Mimbres Mogollon area of Southwestern New Mexico, this paper illustrates how understanding the lithic landscape of a region provides a means to assess behavioral variation in stone procurement practices. The analysis indicates that the differences in mobility and economic pursuits between longer-term residential sites containing pit structures and a shorter-term seasonal residential site with ephemeral architecture structured the raw material procurement practices of site’s occupants. Pit structure sites were focused on agricultural pursuits and used a technology that centered on the production of informal tools fashioned from locally available raw materials. The seasonal residential site focused on wild resources and evidenced greater reliance on formal tool production using raw materials acquired from beyond the immediate vicinity of the site. Despite increasing sedentism and agricultural dependence of the region’s population, some portion of the population exercised seasonal mobility strategies and associated technological and behavioral practices more typical of hunting and gathering populations, suggesting a diverse socio-economic system within the region.     

An Early Upper Palaeolithic Stone Tool Assemblage from Mughr El-Hamamah,Jordan: An Interim Report

Mughr el-Hamamah (Jordan) Layer B contains an Early Upper Palaeolithic stone tool assemblage dating to around 39–45 kya cal b.p. This assemblage is unusual in that it samples human forager activities around the ecotone between the Transjordanian Plateau and the palaeo-lake (Lake Lisan) that filled much of the Jordan Valley during Late Pleistocene times. This paper describes that assemblage, comparing it to other Levantine Upper Palaeolithic assemblages of equivalent antiquity. The Mughr el-Hamamah Layer B assemblage appears most similar to Early Ahmarian assemblages, but it departs from typical such assemblages in ways that may reflect local conditions’ influence on human activities carried out in and near the cave. Mughr el-Hamamah raises new questions about changes in residential mobility, off-site provisioning and foraging activity, and on-site task diversity in the Early Upper Palaeolithic period.     

Ballistic Study Tackles Kinetic Energy Values of Palaeolithic Weaponry

The appearance of new projectile propulsion modes is viewed as an important element for understanding human behaviour during the Palaeolithic. Because the organic components of hunting weapons (the bow, spear‐thrower and arrow, and spear shaft) are only rarely preserved archaeologically, some effort has been invested in experiments to explore how the projecting modes could be identified through the analysis of stone points. The kinetic energy developed by each mode of propulsion has been considered a key variable in these experiments. However, the data used in these studies generally come from a few ballistic studies, with varied results. We present the results of a systematic study conducted with a ballistic pendulum and combined with a classic ballistic analysis. We quantified and compared the kinetic energy developed by the four standard modes of propulsion known for the Palaeolithic. The kinetic energy values that we attained, especially those measured for thrusting spears, clearly differ from what has been assumed up to now, and thus challenge current models on the evolution of hunting technology.     

Hunter-gatherer land use in Late Glacial south-east Italy

This paper is concerned with the Late Palaeolithic settlement of south-eastern Italy at the close of the Pleistocene. The Late Palaeolithic assemblages of the region have been studied previously from a rigid typological stance, with various schemes put forward suggesting evolution of the assemblages through different stages of an Epigravettian tradition, while the potential role of social and economic factors in shaping the various industries has been ignored. This paper shows how the Late Palaeolithic occupation of the region should be considered in relation to the former existence of an extensive coastal plain and to the sea-level rise which submerged it. Factors such as the availability of lithic raw material and the alternative strategies by which it was procured, the particular activities in which the tools were used and the role of the sites within a larger land use system were clearly crucial to assemblage composition.     

Late Pleistocene Lithic Procurement and Geochemical Characterization of the Cerro Kaskio Obsidian Source in South‐western Bolivia

Primary questions regarding the foraging behaviour of the first hunter–gatherers who colonized the New World are how they found, procured and utilized high‐quality raw materials for manufacturing stone tools. In this paper, we present evidence from the late Pleistocene site of Cueva Bautista in the highlands of south‐western Bolivia, which demonstrates that a substantial portion of the recovered stone tool assemblage originated in Cerro Kaskio, a recently discovered obsidian source located 15 km south‐west of the site. In addition to describing the geological and geochronological setting, we provide the first geochemical characterization of the Cerro Kaskio source by means of instrumental neutron activation analysis and energy‐dispersive X‐ray fluorescence. Supported on the technological analysis and archaeometric sourcing of the obsidian lithics found in Cueva Bautista, we discuss the nature of the procurement strategies practised by the earliest mobile hunter–gatherers who explored and colonized the Andean highlands. We conclude that opportunistic lithic resource procurement was probably an important component of the first foraging societies that explored the highland Andes.     

A NOVEL APPROACH TO STUDIES OF PREHISTORIC EXPLOITATION OF STONE TOOL MATERIALS USING MATERIAL COMPOSITION,SURFACE MORPHOLOGY,MICROSTRUCTURE AND MECHANICAL PROPERTIES*

For a comprehensive understanding of material exploitation in prehistory, we applied advanced analytical methods to Japanese prehistoric stone tool materials. Compositions, surface morphologies, microstructures and mechanical properties of the primary lithic materials were analysed. As a result of the tests on actual Palaeolithic artefacts, preferential material selection was observed based on composition, structure and other physical properties of the materials. Homogeneous materials composed of a single type of mineral—α‐quartz—were intentionally selected for Palaeolithic tools regardless of the type of rock. These materials unexceptionally present higher hardness and strength. Moreover, materials composed of extremely fine crystal grains of ~0.1 µm in size with highest hardness and strength were selectively used for sharp‐edged blades. These results lead us to the conclusion that quantitative and objective analyses will give us precise information on prehistoric materials, which will enable us to make an analytical approach to the comprehension of prehistoric exploitation of stone materials. This could eventually complement the traditional interpretation of material exploitation based on conventional petrological classifications.     

SYNCHROTRON FTIR MICRO‐SPECTROSCOPY APPLIED TO THE STUDY OF POLISHED SERPENTINITE ARTEFACTS: A NON‐DESTRUCTIVE ANALYTICAL APPROACH

In prehistory, serpentinite was one of the most frequently used raw materials to produce polished stone artefacts. Several conventional analytical techniques can be applied to identify the serpentine minerals, but their application generally requires a powdered sample. This implies that the artefacts to be analysed must be damaged, and the possibility of analysing a mixture of different serpentine polytypes is high. The use of spatially resolved techniques is therefore a necessity to overcome this problem. Several thin sections of serpentinitic rocks and prehistoric axes have been analysed by synchrotron radiation Fourier transform infrared micro‐spectroscopy. The spectra were acquired directly on specific points of polished stone artefacts and this allowed the recognition of the different polytypes of serpentine minerals without causing any damage to the objects. The results show the infrared micro‐spectroscopy technique to be a useful tool for the characterization of archaeological lithic material.     

An Umm an‐Nar culture stone bas‐relief from Al‐Qutainah,Sultanate of Oman

The Al‐Qutainah stone with its bas‐relief decoration was found in a secondary position, reused through time. The object is clearly a facing stone, originally part of an Umm an‐Nar period tomb, and was subsequently repeatedly reused for making new engravings. While working out the sequence of images it became clear that the very first image was a pair of human figures. This artwork is associated to grave architecture and therefore dates to the Umm an‐Nar period. Two models of interpretation can be suggested, the image of a human pair or the image of a supplicant and deity. Changes in the original meaning of the image indicate conceptual changes in subsequent periods, most probably alterations in the underlying social structure. The importance of the Qutainah stone is not solely due to rare monumental human figurative expression of the period in Oman; furthermore, the find spot in the Adam region is at a distance from the central location of Umm an‐Nar culture that has so far emerged.     

Ground stone tool production and use in the Late Upper Palaeolithic: The evidence from Riparo Dalmeri (Venetian Prealps,Italy)

Abstract

The site of Riparo Dalmeri yielded numerous flint, bone, and shell artifacts, as well as faunal and botanical remains, which are evidence of the Late Upper Palaeolithic (or Late Epigravettian culture, ca. 16,000–12,000 cal b.p.) occupation of the Alps region. The importance of the site is related to the discovery of 267 stones painted with anthropomorphic, zoomorphic, and geometric designs. Here we report on ground stone tools from Riparo Dalmeri investigated by means of an integrated technofunctional and experimental approach to reconstruct their production and use. The results support the hypothesis that the ground stone artifacts were employed in specialized activities (e.g., hide treatment, flintknapping) as well as in the production of some of the painted stone artifacts.     

The Role of Fire in the Life of an Adhesive

The use of fire is essential for the preparation of hafting adhesives; both are suggested to be a proxy for distinguishing the technological expertise and complex cognition among Palaeolithic populations. While use of fire has been argued to exist from about 1.0 Ma onwards, evidence for adhesives in the Palaeolithic record is rare and fragmented. In spite of the close link between fire places and adhesives, no study has ever focussed on examining the impact of heat on adhesive deposition and preservation. This paper discusses the results of a combustion experiment that was undertaken to understand the impact of heat exposure on hafting adhesives. The results have significant implications for archaeological interpretations. Deposition in or near a fire proves to severely impact the types of residues that preserve on a stone tool. The vertically transferred heat is responsible for the loss of adhesives but also for the incidental production of adhesives and their deposition on stone tools. It can be hypothesised that the rare survival of adhesives on archaeological stone tools might not only be the result of direct contact with the fire but also the result of degradation due to heat from overlying fireplaces. If we are to improve our understanding of the preservation of adhesives, it is important to unstand the taphonomic processes that affect these adhesives, in particular heat alteration.     

BLACK AND RED GRANITES IN THE EGYPTIAN ANTIQUITY MUSEUM OF TURIN: A MINERO‐PETROGRAPHIC AND PROVENANCE STUDY

A recent project to investigate the stone artefacts preserved in the Egyptian Antiquity Museum of Turin has been undertaken, with the aim of supplying their systematic classification and suggesting the provenance site of the original raw materials. This paper focuses on seven sculptures dating back to the New Kingdom (18th–19th Dynasties): the statue of Ramses II, three of the 21 sculptures of the goddess Sekhmet, the statue of the goddess Hathor, the Ram‐headed Sphinx and the sarcophagus lid of Nefertari. Petrographic observations have shown that all the sculptures are made of granitoid rocks, with variable composition from granite to granodiorite and tonalite. The observation of strong macroscopic analogies with the so‐called black and red granites outcropping in the Aswan area has suggested a common origin of all the raw materials used for their manufacture. In order to verify this provenance hypothesis, several samples were collected in the Aswan quarry districts. According to results of a minero‐petrographic and geochemical comparison between the statues and the Aswan quarry samples, it was possible to identify the source area of the stone sculptures and finally to highlight the importance of an archaeometric approach to the solution of archaeological problems.     

An overview of bitumen trade in the Near East from the Neolithic (c.8000 BC) to the early Islamic period

The aim of the paper is to summarise the present state of knowledge concerning bitumen trade in the Near East from the Palaeolithic (70,000 BP) to the Early Islamic period. During the Palaeolithic and Early Neolithic period, bitumen utilisation was mostly concentrated in settlements close to oil seeps. From the Ubaid 3 period, bitumen from the Mosul area became more important and was traded as far as the southern Persian Gulf. The Uruk period is a turning point for Mesopotamian history as settlements evolved into city‐states. These cities had a great need for raw materials, and this marks the beginning of large‐scale exploitation of Hit bitumen. This bitumen was traded at settlements along the Euphrates, where a large trade network was established. Hit bitumen entered the Persian Gulf at the turn of the second millennium (Dilmun period). Bitumen from Iraq (Mosul and Hit) became predominantly used in most settlements along the southern coast of the Gulf. During this period Iranian bitumen was also exported and this supply tended to increase, especially during the Partho‐Sasanian period. Dead Sea bitumen had its own exchange network, which was concentrated across present‐day Israel and Egypt where it was extensively used for mummification.     

Neanderthal Shell Tool Production: Evidence from Middle Palaeolithic Italy and Greece

The vast majority of tools recovered from Palaeolithic sites are made of stone varieties. Only rarely do non-lithic implements come to light, let alone tools produced on marine mollusc shell. Interestingly, a good number of shell implements made on Callista chione and Glycymeris sp. valves have been reported from 13 Middle Palaeolithic (Mousterian) sites in southern peninsular Europe. Of these, more than 300 specimens display evidence of deliberate edge retouch. They are all considered products of Neanderthals and date from ~110?ka BP to perhaps ~50?ka BP. In this paper, we review the evidence for Mousterian shell tool production in Italy and Greece??the only two countries in which such tools have been securely identified??and present experimental results obtained in the effort to understand the production process and typo-functional role(s) of the artefacts. We examine the general provisioning pattern of raw materials, as well as the typological, species-related and chronological data pertinent to the production of shell tools by Neanderthals. The data suggest that the Mousterian shell scrapers are a response to poor availability of lithic raw material in the areas of occurrence, and may be best described as an extension of chipped stone technologies to specific types of marine shell, their form defined by an existing mental template. As such, they constitute evidence for refined adaptation strategies and advanced provisioning of resources amongst Neanderthals, and may lend further support to the idea that these hominids displayed a degree of complex behaviour.
