Joint health in free-ranging and confined small bovids – Implications for early stage caprine management

Posted on February 18, 2018 by ARCAS

Publication date: April 2018Source:Journal of Archaeological Science, Volume 92 Author(s): Michaela I. Zimmermann, Nadja Pöllath, Mihriban Özbaşaran, Joris PetersHuman interference with the life cycle of wild ruminant species in the 10th-9th millennia BCE was essential to the ‘Neolithic Revolution’ in the Near East. Being a process of learning by doing, initial ruminant management must have been challenging to both founder flocks and people, but information about potential problems is hitherto lacking in the archaeological record. Here we report on a skeletal condition affecting joint health in small bovids. Detailed examination of the bone surfaces of astragalus of modern and Goitered gazelles as well as wild and domestic sheep revealed circumscribed mesoscopic lesions that we classified into five stages based on their size and properties. Our study demonstrates that intra-articular bone damage is significantly more pronounced in animals living confined to enclosures. Similar non-physiologic conditions have been evidenced in juvenile and adult sheep from early Neolithic contexts throughout Anatolia and interpreted as evidence for locomotor stress due to restricted mobility and stabling on-site. Still in the course of the early Neolithic, joint health improved significantly, implying a better mastering of sheep management over the centuries. In conclusion, pathologic profiling yields the potential for tracing initial management of captive ruminants. Apart from Southwest Asia, the methodological approach presented here seems appropriate for detecting similar developments in the human-animal relationship of behaviorally comparable medium- and large-sized herbivore taxa in other parts of the Old and New Worlds.

Bears and humans, a Neanderthal tale. Reconstructing uncommon behaviors from zooarchaeological evidence in southern Europe

Posted on February 7, 2018 by ARCAS

Publication date: February 2018Source:Journal of Archaeological Science, Volume 90 Author(s): Matteo Romandini, Gabriele Terlato, Nicola Nannini, Antonio Tagliacozzo, Stefano Benazzi, Marco PeresaniCave bear (Ursus spelaeus), brown bear (Ursus arctos), and Neanderthals were potential competitors for environmental resources (shelters and food) in Europe. In order to reinforce this view and contribute to the ongoing debate on late Neanderthal behavior, we present evidence from zooarchaeological and taphonomic analyses of bear bone remains discovered at Rio Secco Cave and Fumane Cave in northeast Italy, an extended geographic area north of the Adriatic Sea. The remains from both caves come from layers dated to 49-42 ky cal. BP, and suggest close interactions between humans and bears, with data not only limited to the association of Mousterian lithic artifacts with numerous bear remains, but also the detection of clearly preserved traces of human modification such as cut and percussion marks, which enable a reconstruction of the main steps of fur recovery and the butchering process. Examples of Neanderthal bear exploitation are extremely sporadic in Europe, and Grotta Rio Secco and Grotta Fumane can be considered rare cases of remain accumulations generated by the human predation of bears of varied age classes during or near the end of hibernation. All of this evidence suggests that bears had a strategic role in the nomadic economy of Neanderthal hunting groups.

Testing the validity of stable isotope analyses of dental calculus as a proxy in paleodietary studies

Posted on February 7, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Samantha D.R. Price, Anne Keenleyside, Henry P. SchwarczStable isotopic analyses (δ13C, δ15N) of dental calculus have been suggested as a proxy for the study of diet of ancient populations but questions about their validity have been raised. Here we test this question, introducing significant improvements in the analysis of δ13C and comparing our results for δ13C and δ15N of calculus with corresponding analyses of associated well-preserved bone which are widely believed to provide reliable paleodiet values. The content of organic material in calculus is decreased by ∼75% compared with modern calculus, resulting in diagenetic changes to δ13C and δ15N of organic matter. Neither δ13C nor δ15N analyses of the organic component of calculus provide accurate estimates of paleodiet. Although δ15N values of dental calculus are correlated with δ15N values of bone collagen from the same individual, it is clear that they have been greatly affected by diagenesis, as shown by a correlation between C/N ratio and δ15N. The inorganic (mineral-bound) carbon component of calculus, analyzed separately from the organic component, gave δ13C values slightly offset from δ13C values of CO3 in bone mineral. Thus it alone appears to have potential as a dietary proxy.

Tracing grog and pots to reveal neolithic Corded Ware Culture contacts in the Baltic Sea region (SEM-EDS, PIXE)

Posted on February 6, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Elisabeth Holmqvist, Åsa M. Larsson, Aivar Kriiska, Vesa Palonen, Petro Pesonen, Kenichiro Mizohata, Paula Kouki, Jyrki RäisänenThe Neolithic Corded Ware Culture (CWC) complex spread across the Baltic Sea region ca. 2900/2800–2300/2000 BCE. Whether this cultural adaptation was driven by migration or diffusion remains widely debated. To gather evidence for contact and movement in the CWC material culture, grog-tempered CWC pots from 24 archaeological sites in southern Baltoscandia (Estonia and the southern regions of Finland and Sweden) were sampled for geochemical and micro-structural analyses. Scanning electron microscopy with energy dispersive spectrometry (SEM-EDS) and particle-induced X-ray emission (PIXE) were used for geochemical discrimination of the ceramic fabrics to identify regional CWC pottery-manufacturing traditions and ceramic exchange. Major and minor element concentrations in the ceramic body matrices of 163 individual vessels and grog temper (crushed pottery) present in the ceramic fabrics were measured by SEM-EDS. Furthermore, the high-sensitivity PIXE technique was applied for group confirmation. The combined pot and grog matrix data reveal eight geochemical clusters. At least five geochemical groups appeared to be associated with specific find locations and regional manufacturing traditions. The results indicated complex inter-site and cross-Baltic Sea pottery exchange patterns, which became more defined through the grog data, i.e., the previous generations of pots. The CWC pottery exhibited high technological standards at these latitudes, which, together with the identified exchange patterns and the existing evidence of mobility based on human remains elsewhere in the CWC complex, is indicative of the relocation of skilled potters, possibly through exogamy. An analytical protocol for the geochemical discrimination of grog-tempered pottery, and its challenges and possibilities, is presented.

Microflint in archaeological sediments from Boker Tachtit, Israel: A new method for quantifying concentrations of small flint fragments

Posted on February 5, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Zane Stepka, Omry Barzilai, Steve Weiner, Elisabetta BoarettoFlint is one of the most common rock types used for producing stone tools. During flint knapping huge amounts of microscopic sized flint particles are produced. Thus the presence of high concentrations of microflint in a sedimentary layer, could be a good indication that flint was knapped at that location. We have developed and tested a method for quantification of microflint concentrations in sediments. The method involves concentrating the microflints in specific density fractions, and then counting a representative proportion of the flint fragments using a polarized light microscope. We show that the method successfully identifies a knapping layer in an Initial Upper Palaeolithic level at the site of Boker Tachtit, Israel. This level also contains macroscopic flint debitage, including refitted artifacts. Microflint quantification can aid in identifying knapping areas and be useful for better understanding site formation processes.

Scientific preparations of archaeological ceramics status, value and long term future

Posted on February 5, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Patrick Sean QuinnThin sections, resin blocks, pressed pellets, fused beads, milled powders, solutions and digested residues are several key sample formats used in the invasive scientific analysis of ancient ceramics. They are crucial tools that enable researchers to characterise the mineralogical, geochemical, molecular and microstructural composition of pottery and other ceramic artefacts, in order to interpret their raw materials, manufacturing technology, production locations and functions. Despite the importance of such preparations, key issues about their status, such as whether they are still artefacts or not, who owns them and where they should reside after analysis, are rarely addressed in the archaeological or archaeometric literature. These questions have implications for the long-term future of thin sections, resin blocks and other sample formats, as well as their accessibility for future research. The present paper highlights the above problem and assess the roles, perspectives and needs of ceramic analysts, field archaeologists, commercial units, curators, policy makers, professional bodies, special interest groups and funding agencies. Finally, guidelines are put forward that can be taken into account when deciding on the value and research potential of scientific specimens of archaeological ceramics, as well as strategies for their curation.

A citation network analysis of lithic microwear research

Posted on February 5, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Christopher J. Dunmore, Ben Pateman, Alastair KeyThe introduction of lithic microwear research into the wider archaeological community by Keeley (1980) was concurrent with the development of the processual paradigm and the adoption of the scientific method. Subsequently, lithic microwear research has benefited from over 35 years of innovation, including the introduction of novel methodological and analytical procedures. The present study employs a citation network to objectively analyse the development of microwear research. Given developments in technology, as well as the institutional isolation of early microwear research, the present analysis considers the citation network that stems from Keeley’s seminal 1980 volume. The 363 papers identified as having cited Keeley (1980) in the subsequent 35 years were treated as individual nodes within the citation network. Before analysis, nodes were assigned attributes, including the type of research published and whether they were supportive of three key aspects of Keeley’s experimental program: the ability to determine the function of the tool and to ascertain the type of worked material from microwear, as well as the use of high-powered microscopy techniques. Emergent properties of the papers, including closeness centrality, indegree and betweenness centrality, are used to test for significant differences between paper attributes. Similarly a clustering algorithm is used to objectively define distinct clusters of important papers within the discipline. Results indicate that a small number of nodes in the network maintain statistically significant influence on the form of the citation network. These important nodes and the distinct ‘schools of thought’ identified are discussed in the context of Keeley’s initial contribution to the sub-field.

Breaking down the bullion. The compliance of bullion-currencies with official weight-systems in a case-study from the ancient Near East

Posted on February 5, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Nicola Ialongo, Agnese Vacca, Luca PeyronelIn this paper we provide an analytical insight on a specific form of bullion-currency. Through the comparison of the statistical properties of different samples of hacksilver and balance weights from various contexts of the Near Eastern Bronze Age, the study attempts to assess whether the weight values of bullion-currencies can be expected to comply with existing weight-standards. The results of the statistical analyses on a silver hoard from Ebla (Syria) strongly suggest that hacksilver in the Bronze Age Near East was shaped and/or fragmented in order to comply with the weight-systems that were in use in the trade networks where it circulated. The results also show the possibility to quantify the level of affinity between different weight-systems. The study is intended to provide a starting point for future research, aimed at the identification of different forms of bullion-currencies in pre- and protohistoric economies.

An insight into the burial practices of the late pre-Hispanic Los Amarillos community (northwestern Argentina) through the study of ancient DNA

Posted on February 5, 2018 by ARCAS

Publication date: March 2018Source:Journal of Archaeological Science, Volume 91 Author(s): Fanny Mendisco, Christine Keyser, Veronica Seldes, Axel E. Nielsen, María Gabriela Russo, Eric Crubézy, Bertrand LudesA palaeogenetic analysis has been undertaken on the pre-Hispanic settlement of Los Amarillos (Regional Development Period, Jujuy Province, Argentina) to reconstruct kin relationship between individuals buried in two domestic areas. The aim of this study was first to genetically characterize the relationships between the individuals buried within the same funerary structure and, secondly, to correlate these genetic data with archaeo-anthropological data to discuss the burial practices and social organization of the Los Amarillos community. An analysis of both uniparental (mtDNA and Y-chromosome) and biparental (autosomal STRs) genetic markers was conducted on eighteen individuals recovered from three different burial structures. The very good DNA preservation contributed to characterize 13 mitochondrial haplotypes, 5 Y-chromosomal haplotypes and 11 complete autosomal STR profiles. The kinship analysis revealed that the domestic areas were used as family graves. Furthermore, they reveal that a maternal lineage is shared by a majority of the studied individuals from different sectors, suggesting matrilocal practices.
