A morphometric system to distinguish sheep and goat postcranial bones.

Distinguishing between the bones of sheep and goat is a notorious challenge in zooarchaeology. Several methodological contributions have been published at different times and by various people to facilitate this task, largely relying on a macro-morphological approach. This is now routinely adopted by zooarchaeologists but, although it certainly has its value, has also been shown to have limitations. Morphological discriminant criteria can vary in different populations and correct identification is highly dependent upon a researcher's experience, availability of appropriate reference collections, and many other factors that are difficult to quantify. There is therefore a need to establish a more objective system, susceptible to scrutiny. In order to fulfil such a requirement, this paper offers a comprehensive morphometric method for the identification of sheep and goat postcranial bones, using a sample of more than 150 modern skeletons as a basis, and building on previous pioneering work. The proposed method is based on measurements-some newly created, others previously published-and its use is recommended in combination with the more traditional morphological approach. Measurement ratios, used to translate morphological traits into biometrical attributes, are demonstrated to have substantial diagnostic potential, with the vast majority of specimens correctly assigned to species. The efficacy of the new method is also tested with Discriminant Analysis, which provides a successful verification of the biometrical indices, a statistical means to select the most promising measurements, and an additional line of analysis to be used in conjunction with the others

Dead or alive?: investigating long-distance transport of live fallow deer and their body parts in antiquity

The extent to which breeding populations of fallow deer were established in Roman Europe has been obscured by the possibility that the skeletal remains of the species, in particular Dama foot bones and antlers, were traded over long distances as objects in their own right. This paper sets out to refine our understanding of the evidence for the transportation of living and dead fallow deer in Iron Age and Roman Europe. To achieve this, museum archives containing purportedly early examples of Dama antler were searched, with available specimens sampled for carbon, nitrogen and strontium isotope analyses, and compared with data for archaeological fallow deer from across Europe. Importantly, the resulting isotope values can be interpreted in light of new modern baseline data for fallow deer presented here. Together these multi-isotope results for modern and archaeological fallow deer provide a more critical perspective on the transportation of fallow deer and their body parts in antiquity

Data sharing reveals complexity in the westward spread of domestic animals across Neolithic Turkey

This study presents the results of a major data integration project bringing together primary archaeozoological data for over 200,000 faunal specimens excavated from seventeen sites in Turkey spanning the Epipaleolithic through Chalcolithic periods, c. 18,000-4,000 cal BC, in order to document the initial westward spread of domestic livestock across Neolithic central and western Turkey. From these shared datasets we demonstrate that the westward expansion of Neolithic subsistence technologies combined multiple routes and pulses but did not involve a set 'package' comprising all four livestock species including sheep, goat, cattle and pig. Instead, Neolithic animal economies in the study regions are shown to be more diverse than deduced previously using quantitatively more limited datasets. Moreover, during the transition to agro-pastoral economies interactions between domestic stock and local wild fauna continued. Through publication of datasets with Open Context (opencontext.org), this project emphasizes the benefits of data sharing and web-based dissemination of large primary data sets for exploring major questions in archaeology (Alternative Language Abstract S1)

Excavations at Dun Ardtreck, Skye, in 1964 and 1965

Dun Ardtreck stands on the west coast of Skye, on a rock knoll with a sheer cliff. It is a small D-shaped drystone strong-hold surrounded by an outer wall and could be one of a small group which had the high broch hollow wall but were not circular towers, termed semi brochs by the writer. The circumstantial evidence for the wall having originally been high is strong, although it is badly ruined now; however, the possibility that the wall was never more than of modest height cannot be completely ruled out. Construction was probably in the first or second centuries AD (Phase 1) and was followed by two distinct phases of occupation. Phase 2 was inside the higher-walled structure where there may have been a wooden roundhouse with a raised floor, although direct evidence is lacking; a central fireplace was not found. A fierce fire put an end to this occupation, the wall was pulled down and an iron door-handle left lying in the passage. A small Roman jar, possibly intact, had already arrived on the site. The ruins were re-occupied in Phase 3 after a ramp had been built against the entrance passage to make access easier. Roman material was inside this ramp and in the secondary deposits and, though it and the native pottery suggested that occupation did not continue beyond the third or fourth centuries, a sherd of E ware on top of this layer implies that it went on at least until AD 500, a conclusion supported by a piece of pumice from about AD 400. Some of the Roman material is unusual for an Atlantic site and there may be special reasons for its presence
