Assessing the function of pounding tools in the Early Stone Age: A microscopic approach to the analysis of percussive artefacts from Beds I and II, Olduvai Gorge (Tanzania)

Posted on September 2, 2016 by

Publication date: October 2016Source:Journal of Archaeological Science, Volume 74 Author(s): Adrián Arroyo, Ignacio de la TorreThis study explores the function of quartzite pounding tools from Olduvai Gorge (Tanzania) using microscopic and use wear spatial distribution analysis. A selection of pounding tools from several Bed I and II assemblages excavated by Mary Leakey (1971) were studied under low magnification (<100×), and the microscopic traces developed on their surfaces are described. Experimental data and results obtained from analysis of the archaeological material are compared in order to assess activities in which pounding tools could have been involved. Results show that experimental anvils used for meat processing, nut cracking and/or bone breaking have similar wear patterns as those observed on archaeological percussive artefacts. This is the first time that a microscopic analysis is applied to Early Stone Age pounding artefacts from Olduvai Beds I and II, and this paper highlights the importance that percussive activities played during the Early Pleistocene, suggesting a wider range of activities in addition to knapping and butchering.

Going south of the river: A multidisciplinary analysis of ancestry, mobility and diet in a population from Roman Southwark, London

Posted on August 31, 2016 by

Publication date: October 2016Source:Journal of Archaeological Science, Volume 74 Author(s): Rebecca C. Redfern, Darren R. Gröcke, Andrew R. Millard, Victoria Ridgeway, Lucie Johnson, Joseph T. HefnerThis study investigated the ancestry, childhood residency and diet of 22 individuals buried at an A.D. 2nd and 4th century cemetery at Lant Street, in the southern burial area of Roman London. The possible presence of migrants was investigated using macromorphoscopics to assess ancestry, carbon and nitrogen isotopes to study diet, and oxygen isotopes to examine migration. Diets were found to be primarily C3-based with limited input of aquatic resources, in contrast to some other populations in Roman Britain and proximity to the River Thames. The skeletal morphology showed the likely African ancestry of four individuals, and Asian ancestry of two individuals, with oxygen isotopes indicating a circum-Mediterranean origin for five individuals. Our data suggests that the population of the southern suburb had an ongoing connection with immigrants, especially those from the southern Mediterranean.

New perspectives on the ecology of early domestic fowl: An interdisciplinary approach

Posted on August 28, 2016 by

Publication date: October 2016Source:Journal of Archaeological Science, Volume 74 Author(s): Jacqueline Pitt, Phillipa K. Gillingham, Mark Maltby, John R. StewartIntroduced into Europe during the Bronze- and Iron Ages as an exotic, non-native species, very little is currently understood about the origins and spread of early domestic fowl, Gallus gallus domesticus. Ecological niche modelling of extant Red Junglefowl, Gallus gallus, presents a unique opportunity to examine historical ecological implications associated with its descendant, the chicken, in early stages of domestication. We model the environmental conditions associated with Red Junglefowl populations both in south-east Asia, where the bird originates, and populations transported further afield as a consequence of human interaction. This allows us to establish the full extent of the ecological tolerance of the ancestor bird. We show that potential for suitable sets of environmental conditions for Red Junglefowl in Europe ranges from poor to limited, based on both current climate and when projecting to mid-Holocene (ca. 4000BCE) climate simulations. This suggests that human intervention played a vital contribution during early domestication to ensure the future widespread success of the chicken. These conclusions offer new insights into the archaeological evidence. We identify areas in the native range as the probable location of first domestication, and not China as has been suggested. We suggest that a dispersal route into Europe via the Mediterranean offers the best ecological potential to aid survival for a recently domesticated version of this species. Identifying the environmental tolerances of Red Junglefowl may also aid future conservation of this species, now highly endangered in its true wild form.

The geoarchaeology of hominin dispersals to and from tropical Southeast Asia: A review and prognosis

Posted on August 18, 2016 by

Publication date: Available online 17 August 2016Source:Journal of Archaeological Science Author(s): Mike W. MorleyTropical Southeast Asia is a critically important region for addressing the major questions and grand challenges that concern us today regarding Late Pleistocene hominin dispersals across the Old World. Geoarchaeological science is widely employed in many regions of the world to contextualise archaeological material and provide an environmental backdrop against which to explore archaeological narratives. However, in Southeast Asia there is an apparent lag in the routine use of this Earth-Science approach despite the abundance of archaeological sites important in explicating past hominin dispersals to and from the region. In this review of the state-of-the-art of geoarchaeological research in Southeast Asia, I examine the role of the discipline in addressing the important issues in archaeology today. I identify where geoarchaeology is being used and to what effect, highlighting gaps in the geoarchaeological dataset. From a methodological point of view it is imperative that archaeologists and geoarchaeologists working in Southeast Asia (and other humid tropical regions of the world) fully appreciate how to interpret the geoarchaeological signatures associated with this climate regime so that methods and practice can be refined. A series of steps that will serve to drive forward geoarchaeological research in the region are also proposed.

Painting Altamira Cave? Shell tools for ochre-processing in the Upper Palaeolithic in northern Iberia

Posted on August 16, 2016 by

Publication date: Available online 16 August 2016Source:Journal of Archaeological Science Author(s): D. Cuenca-Solana, I. Gutiérrez-Zugasti, A. Ruiz-Redondo, M.R. González-Morales, J. Setién, E. Ruiz-Martínez, E. Palacio-Pérez, C. de las Heras-Martín, A. Prada-Freixedo, J.A. Lasheras-CorruchagaMuch of our knowledge of the symbolic world of Upper Palaeolithic hunter-gatherers is based on the study of the graphic representations found in Western European caves. However, to date, few studies have been conducted on rock art apart from chronological and stylistic characterisation. Altamira Cave (northern Iberia) is characterised by an outstanding rock art ensemble, whose representations cover practically the whole Upper Palaeolithic. The site is equally important for the rich Upper Palaeolithic deposits in the cave entrance, which contain large shell assemblages. Traditionally, the presence of shells in hunter-fisher-gatherer settlements has been interpreted as part of the diet and/or the symbolic world (through the creation of ornaments) of these groups, regardless of their possible use as an instrument. In this paper we utilise use-wear methodology, chemical analysis and analytical experimentation to verify the initial hypothesis that shells in the archaeological deposits of Altamira were used to obtain the ochre powder utilised to produce the magnificent and diverse rock art ensemble in the cave. The results provide new information on the process of obtaining pigments for the realisation of paintings and confirm that the use of shells to obtain ochre was a systematic activity throughout the whole study period. Finally, our conclusions support the explanatory model that highlights the role played by marine resources for Upper Palaeolithic human populations.

Quartz backed tools as arrowheads and hand-cast spearheads: Hunting experiments and macro-fracture analysis

Posted on August 13, 2016 by

Publication date: September 2016Source:Journal of Archaeological Science, Volume 73 Author(s): Justin Pargeter, John Shea, Benjamin UttingThe invention of the bow and arrow was a milestone in Late Pleistocene technological evolution. Preservation biases and methodological problems imped our ability to detect its presence in the archaeological record. Currently, South Africa has the earliest suggested evidence for arrowheads, amongst others, small quartz backed tools dating 65–60 ka. These artefacts’ inferred function is based on their small size, micro and macro wear traces and micro-residues recorded on quartz segments from Sibudu Cave. Experimental support for these inferences, or to show that similar artefacts are associated with bow hunting, are however lacking. Here we describe breakage patterns on 150 quartz backed tools hafted as transverse arrowheads and hand-cast spearheads in simulated hunting experiments. These experiments controlled for hafting variability to test the effects of propulsion velocity on the types, patterns and area of diagnostic impact fractures (DIFs). Our results show step terminating bending fracture, spin-off fracture and impactburination frequencies, DIF locations, and ventrally situated DIF frequencies to be robust means of distinguishing arrowheads from spearheads. Our experiments verify previous observations that overall DIF frequencies differentiate between these weapon types. Importantly, we confirm that DIF size is linked to weapon propulsion velocity, but that fracture area is affected by tool area. These findings provide methods for future testing of the hypothesis that bow and arrow technology was in use at least 65 ka in southern Africa and in other regions where quartz was used to tip weapons.
