Small things in perspective: the contribution of our blind tests to micro-residue studies on archaeological stone tools

Our blind tests are distinctive for they were conducted on replicated stone tools used for a variety of tasks that included the processing of animal remains and plants. The analyst was required to differentiate an array of residues from microscopic morphological characteristics, using light microscopy. The original aim of our first tests was to assess the analyst's ability to identify a variety of plant and animal residues, but issues and problems that arose during the testing process made it clear that greater value might be gained from the lessons that we learnt about methodology and the direction for future micro-residue research. We show that problems identified during our first tests stimulated research. Amongst other things, we learnt to distinguish plant and animal remains more confidently than previously. Our residue analyses are firmly embedded in wider archaeological research and our tests help to explain why there are sometimes contradictions between the evidence from archaeologically recovered remains and residues on stone tools. A further outcome of the tests is that we have adopted a multi-stranded approach that provides a cautious, but secure strategy for identifying and interpreting use-residues. Our studies of contaminants through replications have also been invaluable for distinguishing incidental residues from use-related residues.     

仿生合成石质文物二氧化硅保护膜的研究

由于二氧化硅仿生材料具有优越的耐候性,与基底石材相容性好,合成条件的温和性及对环境无污染等优点,为此制备了二氧化硅防护膜。室温下利用CTAB自组装体为模板来调控Na2SiF6水解,在石材表面制备出具有优良性能的SiO2膜,并对膜进行了XRD、SEM分析表征。经过保护处理的石材表面清洁、透明,具有突出的抵抗酸碱性能。生成的保护膜具有良好的透气性,而吸水性有所下降。另外,该保护膜还显示出优良的抵抗高、低温,耐磨,及与基底结合紧密等性能。上述研究表明,仿生SiO2膜将会对石质文物起到更好的保护作用。     

A Case of Ancient Bladder Stones from Oluz Höyük,Amasya, Turkey

A biological object was recovered from the pelvic region of an adult woman coded to SK13 unearthed from Oluz Höyük in Amasya, Turkey. The skeleton was dated to the medieval period on the basis of the burial customs and the calibrated ¹⁴C dates. The find was identified as a bladder stone on morphological, radiographic and chemo‐analytical grounds with the help of X‐ray diffraction, polarised energy dispersive X‐ray fluorescence spectroscopy, confocal Raman spectroscopy, and microscopic techniques. The mineralogical composition of urinary stone was found to be as calcium phosphate (apatite). Bladder stone disease is endemic in poor agricultural regions where the typical diet is mostly based on grain carbohydrate consumption with scarce intake of animal protein.

Milky Quartz Bipolar Reduction and Lithic Miniaturization: Experimental Results and Archaeological Implications

We present experimental data examining the energetics and identification of axial bipolar reduction in contexts of lithic miniaturization on milky quartz. These experiments answer two specific questions. First, does bipolar reduction provide any benefits over freehand reduction? Second, can axial bipolar reduction be distinguished from freehand reduction? Our data show that bipolar reduction requires significantly less time to reduce a percentage unit of core mass and to produce a millimeter of cutting edge on milky quartz than freehand reduction. Milky quartz bipolar reduction surpasses even the cutting edge production efficiency of obsidian pressure blades. We outline a series of quantitative criteria for identifying bipolar cores and flakes. Our results show that bipolar cores and flakes can be distinguished from those produced using freehand reduction by quantifying platform crushing, distal flake rebound scars, bulb shearing, as well as axial, bipolar, and splintered flake terminations. Our results challenge the widely held perceptions about the wastefulness of bipolar reduction and provide clear guidelines for identifying this reduction strategy in archaeological milky quartz assemblages.     

The Farasan Islands,Saudi Arabia: towards a chronology of settlement

An archaeological survey of Saudi Arabia's Farasan Islands in May 2010 recorded a broad range of sites that have not previously been documented. The survey concentrated on Greater Farasan and Segid islands, and comprised a rapid recording of sites shown to the authors by representatives of the Saudi Commission for Tourism and Antiquities. The sites were photographed, their positions logged, sketch drawings made of the principal features and surface pottery drawn and photographed. Detailed drawings were made of a stone anchor and a well with possible Ancient South Arabian carved decoration. The sites visited included settlements, wells, cemeteries and a cave. Several sites included the remains of buildings made of massive ashlar blocks, as well as others of rubble‐stone construction. Datable material at the sites points to several periods of occupation, from the early first millennium BC to early modern times. Some locations were characterised by long periods of settlement. Apart from the findings of this survey, most of the sites remain largely uninvestigated, and suggest significant potential for future research into settlement on the archipelago, as well as into past maritime activity and technology in the southern Red Sea region and beyond.     

Human Technical Behavior in the African Middle Stone Age: The Lithic Assemblage of Porc-Epic Cave (Dire Dawa,Ethiopia)

The African origin of modern humans is the center of a large debate. Discoveries of anatomically modern human fossils in Sub-Saharan Africa correlated to lithic and faunal artifacts show that a “modern Behavior” is associated with the emergence of Homo sapiens. Even though the traits to define this modernity are sometimes difficult to apprehend, the study of the Middle Stone Age cultural phase is important for understanding the origin and evolution of the cognitive capacity of modern humans. Porc-Epic Cave in Ethiopia has a long sequence of Upper Pleistocene occupation. Several thousand bone and lithic artifacts were excavated during three major field excavations (1933, 1974, 1975–76). The lithic assemblage reveals that the relationship between humans and their environment is well organized and that the African terminology is sometimes difficult to apply. This paper proposes a synthesis of all the data, studies and conclusions I have made from the analysis of lithic materials from the 1933 and 1975–76 excavations in order to integrate Porc-Epic into the current debate of MSA and modern human Behavior.L'origine de l'Homme moderne en Afrique fait l'objet actuellement d'un large débat. Les décourvertes de fossiles d'Homo sapiens en Afrique sub-saharienne associés à des industries lithiques montrent que, en parallèle à l'émergence de cette nouvelle espèce humaine, un comportement dit moderne s'est développé. Le Middle Stone Age est donc une période culturelle charnière dans l'évolution comportementale de l'homme. La grotte du Porc-épic, en éthiopie, est un témoignage de cette ère avec un remplissage pléistocène supérieur contenant des dizaines de milliers de restes fauniques et lithiques. L'étude de son important assemblage lithique révèle que le rapport de l'homme à la matière et à son environnement est très organisé et que le terminologie culturelle africaine est parfois difficile à utiliser.     

Dot-in-circle: An ethnoarchaeological approach to soft-stone vessel decoration

Discovery of the zahrah carving tool on a trip to the Ru'us al-Jibal/Musandam Peninsula provided the impetus for the following ethnoarchaeological examination. Ethnographic information recovered from numerous interviews is outlined in detail. The connection between the various carving tools used by the Shihuh tribes in this region and the dot-in-circle motif is investigated. Similar artefacts recovered from archaeological sites are also reviewed and implications discussed.     

Miscellaneous Artifacts From Casselden Place, Melbourne

The miscellaneous artifacts from Casselden Place derive from an urban working-class community in nineteenth-century Melbourne, Australia. They include a broad range of items associated with work, recreation, education, fashion, food consumption, health, and other facets of everyday life. In this paper the miscellaneous assemblage is examined in light of research questions relating to health and hygiene, leisure and work, and access to luxury items amongst the working-class of the mid to late nineteenth century.
