Copper supply during the Final Neolithic at the Saint-Blaise/Bains des Dames site (Neuchâtel, Switzerland)
2009
The Saint-Blaise/Bains des Dames stratified site in Neuchâtel, Switzerland, contains several occupations that span the Late through Final Neolithic, including the Horgen, Lüscherz, and Auvernier-Cordé periods. As part of a study on prehistoric metallurgy in western Switzerland, we compare the lead isotope ratios (multicollector inductively coupled plasma mass spectrometer) and elemental compositions (instrumental neutron activation analysis) of the site's numerous copper finds to a database of corresponding measurements for copper ores throughout Europe. The results show a considerable variation in copper compositions present at the site, suggesting complex economic relationships and multip…
Geomeasure: GIS and Scripting for Measuring Morphometric Variability
2019
This paper presents Geomeasure, a methodological tool developed to recover typometric information with a twofold objective. First, to speed up the process of gathering data by automatizing the way in which it is recovered. Second, it adds higher accuracy and the possibility of re-measuring archeological items without further directly interacting with the piece. Based on a combination of R scripting with GIS features, Geomeasure is at the time able to automatically gather 125–130 typometric variables per archaeological item, with the only input of vectorized photographs. It can be used as a reliable methodological aid to extract detailed information on patterns and trends of shape variabilit…
Charcoal-painted images from the French Neolithic Villevenard hypogea: an experimental protocol for radiocarbon dating of conserved and in situ carbo…
2020
A conserved painting removed from a Neolithic collective grave in Marne, France, provided an opportunity for radiocarbon dating to place Les Ronces Hypogeum 21 (Villevenard) into the chronology of that region. Chemical analysis with direct analysis in real time (DART) mass spectrometry, Fourier transform infrared (FTIR) spectroscopy and gas chromatography-mass spectrometry (GC-MS) of samples from the painting revealed the presence of two kinds of wax (beeswax and paraffin or microcrystalline wax) that likely were added during the conservation, a drying oil like linseed oil, as well as markers of pine resin that may arise from turpentine or colophony. A new pretreatment protocol of chlorofor…
Images of camels on a mammoth tusk from West Siberia
2020
International audience; This study introduces the engravings on a mammoth tusk from the lower reaches of the Tom River in WestSiberia. The tusk was found in 1988 during construction works and was later transferred to the Tomsk StateUniversity, but it remained almost unknown to specialists until now. Radiocarbon dating by AMS reported theage of the tusk as 13,100–13,005 Сal BP (95% confidence level). The surface of the tusk is engraved with imagesof two-humped camels arranged in two pairs. In addition, arrows and wounds within the contours of the animalscan be seen. The comparative analysis of the stylistic features of the camel figures shows that they correspond tothe age of the tusk itself, …
The influence of religious identity and socio-economic status on diet over time, an example from medieval France
2019
International audience; In Southern France as in other parts of Europe, significant changes occurred in settlement patterns between the end of Antiquity and the beginning of the Middle Ages. Small communities gathered to form, by the tenth century, villages organized around a church. This development was the result of a new social and agrarian organization. Its impact on lifestyles and, more precisely, on diet is still poorly understood. The analysis of carbon and nitrogen isotopes in bone collagen from the inhabitants of the well-preserved medieval rural site Missignac-Saint Gilles le Vieux (fifth to thirteenth centuries, Gard, France) provides insight into their dietary practices and enab…
The first archaeometric characterization of obsidian artifacts from the archaeological site of Samshvilde (South Georgia, Caucasus)
2019
This paper presents the first results about the provenance of obsidian fragments recovered in the archaeological site of Samshvilde (South Georgia, Caucasus) with the aim to obtain knowledge related to the network distribution and procurement of obsidian in Georgia. The geochemical characterization of thirty archaeological finds was obtained by the LA-ICP-MS method, an almost non-destructive technique capable of chemically characterizing the volcanic glass. A comparison of geochemical results obtained on both archaeological artefacts and geological samples collected from Chikiani outcrop in Georgia, together with literature data of southern Caucasus and eastern Turkey, allowed us to define …
Seasonal and habitat effects on the nutritional properties of savanna vegetation: Potential implications for early hominin dietary ecology.
2019
The African savannas that many early hominins occupied likely experienced stark seasonality and contained mosaic habitats (i.e., combinations of woodlands, wetlands, grasslands, etc.). Most would agree that the bulk of dietary calories obtained by taxa such as Australopithecus and Paranthropus came from the consumption of vegetation growing across these landscapes. It is also likely that many early hominins were selective feeders that consumed particular plants/plant parts (e.g., leaves, fruit, storage organs) depending on the habitat and season within which they were foraging. Thus, improving our understanding of how the nutritional properties of potential hominin plant foods growing in mo…
Not only flint: Levallois on quartzite and limestone at Abrigo de la Quebrada (Valencia, Spain): Implications for neandertal Behavior
2016
This paper investigates the application of the Levallois technique to the knapping of nonflint raw materials (limestone and quartzite) in the upper levels of the Abrigo de la Quebrada rockshelter (Chelva, Valencia, Spain). Besides highlighting the significant flexibility that characterized Neandertal behavior, such an application is of singular interest because goodquality flint—lacking fissures and impurities and presenting a compact and homogeneous texture—is abundant in the site’s immediate vicinity. In other assemblages, the scarcity or poor quality of flint often suffices to explain the recourse to alternatives, but in these Quebrada levels raw material choice must be primarily determi…
Introduction. Leave no stone unturned: Perspectives on ground stone artefact research
2016
Ground stone tools served in many physical and social contexts through millennia, reflecting a wide variety of functions. Although ground stone tool studies were neglected for much of early archaeology, the last few decades witnessed a notable international uptick in the way archaeologists confront this multifaceted topic. Today, with the advance of archaeology as a discipline, research into ground stone artefacts is moving into a new phase that integrates high resolution documentation with new methodological, analytical techniques, and technological approaches. These open new vistas for an array of studies and wide-ranging interpretive endeavours related to understanding ground stone tool …
Antropologia come "general Weltkenntniß" Kant e la concezione cosmica dell'umano
2018
Il progetto antropologico di un mondo-ambiente nel quale l'uomo, grazie allo sviluppo delle proprie capacità, trova la sua posizione e conquista un ruolo centrale, si inserisce, in Kant, all'interno in un disegno più ampio che pone l'uomo al cospetto di scopi la cui realizzazione va ben al di là di quel che egli può fare; va ben al di là dell'immagine pragmatica di un mondo pensato e progettato a misura d'uomo. Come risulta insufficiente, dunque, ogni antropologia fisiologica che rimanga limitata al punto di vista dell'uomo in quanto prodotto del gioco della natura, altrettanto insufficiente risulterebbe un'antropologia pragmatica che si legasse unicamente alla rappresentazione antropocentr…
