The RESET project: constructing a European tephra lattice for refined synchronisation of environmental and archaeological events during the last c. 100 ka

This paper introduces the aims and scope of the RESET project (. RESponse of humans to abrupt Environmental Transitions), a programme of research funded by the Natural Environment Research Council (UK) between 2008 and 2013; it also provides the context and rationale for papers included in a special volume of Quaternary Science Reviews that report some of the project's findings. RESET examined the chronological and correlation methods employed to establish causal links between the timing of abrupt environmental transitions (AETs) on the one hand, and of human dispersal and development on the other, with a focus on the Middle and Upper Palaeolithic periods. The period of interest is the Last Glacial cycle and the early Holocene (c. 100-8 ka), during which time a number of pronounced AETs occurred. A long-running topic of debate is the degree to which human history in Europe and the Mediterranean region during the Palaeolithic was shaped by these AETs, but this has proved difficult to assess because of poor dating control. In an attempt to move the science forward, RESET examined the potential that tephra isochrons, and in particular non-visible ash layers (cryptotephras), might offer for synchronising palaeo-records with a greater degree of finesse. New tephrostratigraphical data generated by the project augment previously-established tephra frameworks for the region, and underpin a more evolved tephra 'lattice' that links palaeo-records between Greenland, the European mainland, sub-marine sequences in the Mediterranean and North Africa. The paper also outlines the significance of other contributions to this special volume: collectively, these illustrate how the lattice was constructed, how it links with cognate tephra research in Europe and elsewhere, and how the evidence of tephra isochrons is beginning to challenge long-held views about the impacts of environmental change on humans during the Palaeolithic. © 2015 Elsevier Ltd.RESET was funded through Consortium Grants awarded by the Natural Environment Research Council, UK, to a collaborating team drawn from four institutions: Royal Holloway University of London (grant reference NE/E015905/1), the Natural History Museum, London (NE/E015913/1), Oxford University (NE/E015670/1) and the University of Southampton, including the National Oceanography Centre (NE/01531X/1).

A preliminary investigation of two prehistoric cave sites in Southern Albania

In this article we describe the evaluation of two prehistoric sites situated within the coastal zone of south-western Albania, originally investigated by the Italian prehistorian Luigi Cardini in 1939. The first is a cave site in the town of Himara; the second a rock-shelter at Kanalit in the Acroceraunian Mountains to the north. Investigations at both locations revealed stratified evidence of prehistoric activity dating from the mid-Holocene. At Kanalit, an extensive lithic assemblage provided evidence for the exploitation of the adjoining coastal lowlands during the Mesolithic, while at Himara, a largely unbroken sequence of deposits records often intensive human activity at the cave from the Early Bronze Age. Radiocarbon dates have provided a significant independent chronological marker for Early/Middle Bronze Age horizons. The ceramic evidence indicates a predominance of local influences, the site not becoming part of wider trading networks until the late Iron Age, c. seventh to sixth centuries BC

pXRF analysis of obsidian artifacts from Albania: Crossroads or cul-de-sac?

Archaeologists first identified obsidian artifacts in Albania in the early 20th century, but their numbers were small and the contexts insecure. Their source was never determined. Nor was it clear why, given the large numbers of obsidian artifacts recovered in regions to the south and north, in areas like central and southern Greece and Croatia, more obsidian artifacts were not found in Albania. In an attempt to address these problems in Albanian prehistoric archaeology, we analyzed eight obsidian artifacts from six sites – out of a total of only 16 known pieces from the entire country, many of which are now lost – using portable X-ray fluorescence spectroscopy (pXRF). One of these, from the Putanja site, is from Lipari, Italy. The other seven are from Melos, Greece. All eight appear to date from the Middle/Late Neolithic to Late Bronze Age (5500–1050/25 BCE). The absence of obsidian in Albania is not the result of poor archaeological sampling; several, recent intensive surface surveys and excavations in south and north Albania produced no obsidian. Rather, it may be that obsidian was not imported to prehistoric Albania due to the presence of abundant, accessible, very fine flint sources, located in particular in the southwest of the country. Consequently, the prehistoric inhabitants of Albanian were out of the loop or otherwise uninterested in obsidian during those periods of Mediterranean prehistory, specifically from the Late Neolithic to the Bronze Age, when it was traded most extensively. © 2019 Elsevier Lt
