Micro-photogrammetric and morphometric differentiation of cut marks on bones using metal knives,quartzite, and flint flakes

In a previous article, we presented an innovative method to analyze cut marks produced with metal tools on animal bones from a metrical and tridimensional perspective (Maté-González et al. 2015). Such analysis developed a low-cost alternative technique to traditional microscopic methods for the tridimensional reconstruction of marks, using their measurements and sections. This article presents the results of an experimental study to test this photogrammetric and morphometric method for differentiating cut marks generated with metal, flint, and quartzite flakes. The results indicate statistically significant differences among cut marks produced by these three types of raw material. These results encourage the application of this method to archeological assemblages in order to establish a link between carcass processing and lithic reduction sequences on different raw materials and also to define the kind of tools used during butchery.

Archaeomagnetic data from three Punic sites in Tunisia

Archaeomagnetic analyses on bricks and slag fragments from kilns have been undertaken. Four new archaeomagnetic directions and two new archaeomagnetic intensities have been reported for three Punic sites in Tunisia. The SCHA.DIF.3K archaeomagnetic model gives the most consistent age estimates, in agreement with the archaeological ages for three of the four analyzed kilns. The archaeomagnetic models appeared to be surprisingly proficient both using archaeodirections and intensities for El Maklouba. The existence of kilns from different chronological archaeological phases (4th–3th century BC and 2nd–3rd century AD) has been confirmed for this site. The archaeological hypothesis that associates the kiln in El Gaala with the neighboring Punic necropolis is compatible with the archaeomagnetic data obtained from the kiln, though a modern use or remagnetisation of the kiln cannot be excluded.     

Archaeometric analysis of Late Roman amphorae from <Emphasis Type="Italic">Africa</Emphasis> in the ancient city of <Emphasis Type="Italic">Iluro</Emphasis> (Mataró, Catalonia,Spain)

In this paper, the results of the archaeometric study of an assemblage of Late Roman amphorae, found in several contexts from the ancient city of Iluro (Mataró, Catalonia, Spain) and with a presumable origin in Roman Africa, is presented. A total of 57 samples have been analysed, by means of optical microscopy (thin-section analysis), X-ray fluorescence and X-ray diffraction, in order to obtain an integrated petrographic, chemical and mineralogical characterisation and, from this data, to shed light on their provenance. The results indicate the presence of a large number of fabrics, most of them with a Tunisian provenance; a fabric probably from Algeria was also found, as well as a few chemical-petrographic loners that should be related to a provenance out of Africa. Concerning the Tunisian fabrics, the comparison with data from production centres allows for a more precise provenance hypothesis for many of them. These results are useful for the study of the trade networks of Iluro in Late Antiquity, since they provide new evidence on the diversity of transport amphorae that were arriving to this urban centre in Hispania Tarraconensis, showing a more complex reality than initially suggested by the archaeological evidence.     

Massive storage in As Laias/O Castelo (Ourense,NW Spain) from the Late Bronze Age/Iron Age transition to the Roman period: a palaeoethnobotanical approach

The highest platforms of As Laias, a settlement located in northwest Iberia, were used for storage during the Iron Age and until the turn of the Era. In this time-span, the whole hilltop – the croa – was a walled enclosure mostly used for storage and due to recurrent fires affecting the settlement's terraces, abundant plant remains were preserved in overlying wattle and daub storage structures.     

Social Cooperation and Resource Management DynamicsAmong Late Hunter-Fisher-Gatherer Societies in Tierra del Fuego (South America)

This paper presents the theoretical basis and first results of an agent-based model (ABM) computer simulation that is being developed to explore cooperation in hunter–gatherer societies. Specifically, we focus here on Yamana, a hunter-fisher-gatherer society that inhabited the islands of the southernmost part of Tierra del Fuego (Argentina–Chile). Ethnographical and archaeological evidence suggests the existence of sporadic aggregation events, triggered by a public call through smoke signals of an extraordinary confluence of resources under unforeseeable circumstances in time and space (a beached whale or an exceptional accumulation of fish after a low tide, for example). During these aggregation events, the different social units involved used to develop and improve production, distribution and consumption processes in a collective way. This paper attempts to analyse the social dynamics that explain cooperative behaviour and resource-sharing during aggregation events using an agent-based model of indirect reciprocity. In brief, agents make their decisions based on the success of the public strategies of other agents. Fitness depends on the resource captured and the social capital exchanged in aggregation events, modified by the agent’s reputation. Our computational results identify the relative importance of resources with respect to social benefits and the ease in detecting—and hence punishing—a defector as key factors to promote and sustain cooperative behaviour among population.
