Wear Analysis on Early Mesolithic Microliths from the Verrebroek Site,East Flanders,Belgium

Abstract

This paper discusses the results of recent wear analysis on a series of 467 microliths excavated at the early Mesolithic (8410–7930 cal B.C.) site of Verrebroek in Belgium. Based on both macro-fractures (bending fractures and spin-offs) and traces of microscopic linear impact a distinction could be made between non-geometric microliths used as tips and geometric microliths mainly used as barbs. During the Pre-boreal the latter occur in large numbers and in various forms (triangles, crescents) that are used in mutually exclusive ways. At the transition from the Pre-boreal to the Boreal, almost simultaneously with the disappearance of bone and antler points from the Mesolithic tool kit there is a considerable increase in microlith tips. In this paper several possible explanations for this change are discussed.     

Design and performance of microlith implemented projectiles during the Middle and the Late Epipaleolithic of the Levant: experimental and archaeological evidence

The study comprises an experimentally based investigation of interaction between temporal change in the morphology of microlithic tools and transformations in projectile technology during the Late Pleistocene in the Levant. Archery experiments with differently designed arrows fitted with various types of microliths representing subsequent Epipaleolithic cultures of the Levant allowed analyzing performance abilities of the arrows, identifying projectile damage types characteristic of particular hafting modes, detecting factors influencing the frequency of projectile damage and estimating the frequency of projectile damage expected to be found in archaeological samples. The data obtained through the experiments applied in the analysis of the archaeological microliths from Geometric Kebaran and Natufian sites in Israel indicate different approaches to the design of projectiles fitted with microliths characteristic for these cultures. The shift in design, associated with such important economic and social transformations as transition to sedentary settlements and a broad-spectrum economy, may reflect a demand for light, flexible and efficient projectile weapons requiring low time and labor investment for preparation and retooling. The use of such efficient weapons in conditions of growing population density and restricted areas available for Natufian hunter–gatherers can be considered as one of the factors that could have affected the subsequent transition to food production that took place in the early Holocene.     

Assessing Hafting Adhesive Efficiency in the Experimental Shooting of Projectile Points: A new Device for Instrumented and Ballistic Experiments

With the aim of providing better control of shooting experiments performed with replicas of prehistoric projectiles, we have conducted an instrumental archaeology study on the efficiency of prehistoric projectile points by placing emphasis on their adhesion and ballistic characteristics. In order to avoid any reproducibility problems, hafting adhesives were made with controlled mixtures of commercial rosin (also called ‘colophany’) and beeswax added as a plasticizer. An original experimental device has been developed to instrument a bow, allowing the control of both the trajectories and the velocities of the different shoots. In the course of an experimental programme on Sauveterrian microliths from the Mesolithic period of the South of France, the experimental system was applied to composite replica projectile tips of Mesolithic hunters. Arrows being shot at transparent targets were filmed in order to evaluate the penetration length and residual damage. Interestingly, this study reveals that the properties of the mixture are highly dependent on the velocity of the arrows. It was shown that—contrary to previous experiments that usually used a mixture in which rosin predominates— the most efficient adhesive is made of 70 wt% beeswax with only 30 wt% rosin. This result is of great importance for improving further shooting experiments and overcoming the problems frequently mentioned due to the loss of the flint armatures before they reach the animal target, or at least before penetration. When using this appropriate mixture, the lateral armatures are resistant to most of the shots. Experiments performed on real boars’ flesh have also shown that the presence of lateral microliths allows the laceration inflicted on the target to be enlarged. Finally, a critical parameter has been identified, which is the location on the arrow of the microlithic element.     

The paleolithic site of Longwangchan in the middle Yellow River,China: chronology,paleoenvironment and implications

The Longwangchan Paleolithic site, situated on the Yellow River terraces in the Hukou area, Shaanxi province, China, was found in 2003–2004, and two areas (Localities 1 and 2) of the site were excavated in 2005–2008. Abundant stone artifacts including microliths, a grinding stone fragment and a shovel, with some animal bones and shells, were recovered from Locality 1. In this study, the cultural deposits from Locality 1 were dated using radiocarbon and optical dating techniques, and the sediment properties of the deposits were analyzed. The results show that the age of the deposits ranges from 29 to 21 ka and most of them were deposited between 25 ka and 29 ka. This indicates that corresponds to late Marine Isotope Stage (MIS) 3 and early MIS 2. During the human occupation period, the climate in this area became colder and drier. Sediments from beds where the grinding slab and the shovel were found were dated to ∼25 ka, which is the oldest among the grinding stones found in China. The microliths and the grinding stone are important evidence for an incipient socio-economic process that eventually led to the regional transition from hunting-foraging to farming.

AN INTERIM REPORT OF THE STAR CARR MICROWEAR STUDY

Summary. This paper presents some preliminary observations based on the microwear analysis of 173 artefacts from the mesolithic site of Star Carr, near Scarborough, Yorkshire. One hundred discrete and utilized edges were identified by the presence of various microwear traces on 79 of the artefacts belonging to the following general types: scrapers, edge-damaged or marginally retouched blades and flakes, bilaterally backed blades (awls), burins, backed blades, axe resharpening flakes, denticulated or truncated blades and flakes, microliths, and cores. The microwear traces identified on the tools indicates that they were used in a variety of ways in the processing of hide, bone, wood, antler and meat. A comparison of wear-traces and tool shape has shown that there are morphological differences between scrapers used on hide and those used on bone, and also, that edge-damaged or marginally retouched blades were selected for use on the basis of their cross-sectional configuration.

Experimental and archaeological investigations of backed microlith function among Mid-to-Late Holocene herders in southwestern Kenya

This study takes an experimental and comparative approach in order to evaluate the circumstances driving the deployment of microlithic tool technologies by food-producing mobile herders during the Mid-to-Late Holocene in southern Kenya. The predominately obsidian microliths used by contemporaneous, but culturally distinct, herding communities were replicated and used as arrow tips in archery experiments and within composite knives used in animal processing. This allowed for patterns of damage associated with production, different forms of projectile use, and butchery to be identified on microlithic specimens and evaluated against each other to assess the criteria for diagnostic macrofracture and wear patterns reflective of each activity. Experimentally generated criteria were used to identify the most likely functions for microlithic tools in three archaeological assemblages belonging to early Kenyan pastoralists. The analyses showed that while the same microlithic form is shared by culturally distinct groups across a wide time range, these tools were being used to vary different functions that do not clearly correlate with subsistence economy, culturally affiliation, or time period. Environmental variability and instability throughout the Late Holocene likely contributed to the persistence of highly adaptable microlithic toolkits. These data contribute to ongoing dialogues on the emergence and evolution of microlithic toolkits.     

Testing hypotheses of independence on symmetrical artifacts

Independence between attributes on artifacts with two equivalent loci has ordinarily been tested only when the loci can be differentiated from each other, say as left or right side or as distal or proximal end. If such an identification does not exist, is uncertain or is irrelevant, then a test of independence requires a special statistical procedure. Such a procedure is given here. Applications are illustrated for coreplatforms, geometric microliths and arrow-head typology, and an extension to artifacts with several equivalent loci is determined.     

On Cross-Legged Effigies Commonly Appropriated to Templars

Central England has previously represented a blank area for mesolithic studies. This article endeavours to correct this with the publication of the microlithic component of three prolific surface assemblages from sites on the east Warwickshire plateau. The microliths, of later mesolithic type, are described and analysed in detail, and are shown to be noteworthy for the inclusion of large numbers of inverse basally retouched points. The assemblages are placed in their English context, and the significance of their distribution discussed.     

Aksumite Lithic Industries

A preliminary account is given of a previously unrecorded, abundant, and varied classical and late Aksumite use, in a sophisticated urban context, of carefully made stone scrapers and backed microliths with close affinities to their local Late Stone Age precursors. Examination of microscar patterns on these artifacts has provided an additional source of new information about Aksumite technical, economic, and social practices.Un rapport préliminaire de l'usage, en Axoum pendant les périodes classique et dernier, d'un grand nombre des grattoirs et des microlithes à bord abattu, biens fabriqués et des formes divers. Ces outils lithiques, qui viennent d'un contexte urbain, ont les affinités nombreuses avec les outils de l'âge de la pierre récent dans cette localité. Une étude microscopique des traces d'emploi des outils a donné une nouvelle source d'information sur les pratiques technologique, economique et social d'Axoum.     

A Segment is not a Monolith: evidence from the Howiesons Poort of Sibudu,South Africa

Segments from the Howiesons Poort of Sibudu, South Africa, can be separated into at least three populations based on quartz, hornfels and dolerite rocks used for their production. Length, breadth, thickness and tip cross-sectional areas are significantly different between segments made on the three rock types. Segments are not monoliths, and they were not intended as a single tool type, they were flexible enough to be mounted to shafts in a variety of ways. Several hafting strategies are evident, including the use of different adhesive recipes. Most segments were probably parts of hunting weapons, based on use trace analysis, but weapon types varied. Quartz segments have standardized shapes (short and deep), perhaps because they were hafted as transverse arrowheads. While hornfels and dolerite segments may on occasion also have been parts of projectiles, the large dolerite segments could sometimes have served as parts of spearheads, with two segments hafted back-to-back. Howiesons Poort segment technology is sophisticated; its makers appreciated distinct properties of rocks, their flaking, wear and impact possibilities. Further, they recognized the best sizes and shapes for use with each kind of weapon, they understood the qualities and applications of various adhesive recipes, and they knew how to make a variety of hafts from materials that included bone and wood.     

The Kulbulak Bladelet Tradition in The Upper Paleolithic of Central Asia

The article describes lithic industries of the Upper Paleolithic levels of Kulbulak, Uzbekistan, a key site in southwestern Central Asia based on materials from excavations at several sites in the western and northwestern Pamir– Tien Shan region (Kulbulak, Kyzyl-Alma-2, Dodekatym-2, and Shugnou). A new cultural and technological tradition is introduced, for which the authors suggest the name Kulbulakian. Its distinctive features are the bladelet technique and a microlithic set including backed pieces and triangular microliths. Stages in the evolution of the Kulbulakian tradition are reconstructed: origins, development, peak, and disappearance of the carinated technology. Industries belonging to this tradition have shaped the general appearance of the Upper Paleolithic in the area in question.     

LIME PLASTER AS AN ADHESIVE FOR HAFTING EIGHTEENTH-DYNASTY FLINT SICKLES FROM TELL EL DAB'A,EASTERN NILE DELTA (EGYPT)*

A combination of analytical techniques, including thin-section observations, scanning electron microscopy, X-ray diffraction and X-ray fluorescence analysis, was applied to study the nature and origin of an adhesive used for mounting flint sickle blades to a wooden handle, recovered from early Eighteenth Dynasty culture layers of the multi-layer settlement at Tell el Dab'a, Lower Eygpt. The results obtained from these investigations led to the conclusion that the adhesive is a pure lime plaster, thus providing the oldest evidence for the use of this material as a binding agent so far known in ancient Egypt.

Adhesive Production and Pottery Function During the Iron Age at the Site of Grand Aunay (Sarthe,France)*

A combination of elemental, functional and molecular analyses performed on amorphous organic residues dating from the Iron Age was developed in order to identify these remains and to understand their relationship with ceramic vessels in which some of them were found. These analyses made it possible to distinguish between ceramic vessels used for the production or storage of adhesive materials, mainly birch bark tar, and those dedicated to the preparation of culinary commodities, which contained animal fats. The organization of the production of adhesives is described and the addition of beeswax to birch bark tar is reported for the first time. The use of birch bark tar for coating ceramic vessels is also discussed.     

Neolithic Adhesive from a T‐shaped Ornamental Element Excavated at Site 14 at Kowal,Kuyavia, Central Poland

We conducted an identification of a substance isolated from a T‐shaped ornamental element excavated from a Globular Amphora Culture tomb at the Kowal 14 archaeological site in Poland. ¹⁴C dating indicated 4105 ± 35 bp (POZ‐21912) and 3990 ± 50 bp (POZ‐21910). Analytical methods such as SEM–EDS, XRD and FT–IR were applied to study the origin of its structure. The results of instrumental analysis and the archaeological context indicate that the adhesive substance investigated consists mainly of calcium carbonate (calcite, 78–88%), silica dioxide (quartz), sodium aluminium silicate (albite) and potassium aluminium silicate (microcline). The material might be a man‐made, mineral adhesive, a kind of lime mortar. The object is considered as the oldest European finding of this type outside the Mediterranean Basin. It provides evidence for the use of the lime calcination process in Central Europe as early as in the Late Neolithic, for which there were—up to now—no convincing premises.     

Investigations at Tor al-Tareeq: An Epipaleolithic Site in the Wadi el-Hasa,Jordan

Abstract

The Epipaleolithic site of Tor al-Tareeq (WHS 1065) was discovered in 1982 by Burton MacDonald's Wadi Hasa Survey in west-central Jordan, surface collected and tested in 1984, and partially excavated in 1992. The earliest and best represented occupation is an early Epipaleolithic industry, overlain in places by an ephemeral geometric industry identified by a higher incidence of geometric microliths. Six radiocarbon determinations span the period between 16,900 and 15,600 b.p. and confirm an early Epipaleolithic date but the subsequent geometric phase has not been dated. The site consists of a series of camps, near a collapsed rockshelter and a spring, and strung out along the shore of a mildly-alkaline, late Pleistocene lake. The permanent water and varied resource zones surely made the locale attractive in an otherwise arid landscape. Faunal remains and pollen from the site indicate diverse resources in conditions substantially different from those of today. This report examines a wide range of archaeological and paleoenvironmental data in order to understand aspects of the regional system of settlement and subsistence of which Tor al-Tareeq was a part. Continuing research in the eastern Hasa drainage seems likely to provoke a reassessment of current models of hunter-gatherer adaptation during the Epipaleolithic in the southern Levant.     

Small shifts in handedness bias during the Early Mesolithic? A reconstruction inferred from Microburin technology in the eastern Italian Alps

This study discusses the existence of a variability recorded in lateralization indexes of proximal microburins, a by-product of the individual manufacture of microliths, in a sample of Sauveterrian sites from the Italian Eastern Alps. At first glance, such variability may appear to support the existence of customary handling, pertaining perhaps to an ensemble of normalized technical procedures accomplished by the members of the human group regardless of site type, context and economic activities. However, plotting the patterns in lateralization index against the regional Sauveterrian chrono-cultural sequence reveals a diverse correlation emerges and indicates how the early settlement phase involved greater functional differentiation among sites used by selected human groups compared with the successive phases, when this pattern vanishes. This trend may correspond to the decrease in lateralization observed on skeletal markers from the Upper Paleolithic to the Mesolithic, linked to the change in technological models and techniques employed in food gathering. The implications of this research at different levels are also discussed.     

Exploitation of Beehive Products,Plant Exudates and Tars in Corsica During the Early Iron Age

In the north‐western Mediterranean area, the first Iron Age is characterized by intense contacts and cultural interactions between populations. Archaeological remains such as ceramic vessels or metal and glass objects are usually good indicators of the nature and the intensity of these exchanges, but can also be used to determine the way in which these populations were living at their time. In contrast, organic substances, despite their importance in a wide variety of activities, are rarely investigated due to their low degree of preservation. The recent discovery of a series of amorphous organic residues with adhesive properties at the site of Cuciurpula provided a unique opportunity to address questions related to the types of natural substances exploited, their provenance, their uses and their informational input to intercultural relationships. Our results, based on GC and GC–MS analysis of organic residues preserved at the site of Cuciurpula, provide strong evidence for the most southern use of birch bark tar in Western Europe, and also for the simultaneous use of this substance with pine resin. Beeswax was also identified in some samples. The combined study of residue composition, aspect and location on ceramic sherds reveals a variety of uses, highlighting a complex technical system.
