Fires at Neumark-Nord 2, Germany: An analysis of fire proxies from a Last Interglacial Middle Palaeolithic basin site
2016
Few sites with evidence for fire use are known from the Last Interglacial in Europe. Hearth features are rarely preserved, probably as a result of post-depositional processes. The small postglacial basins (
Flore turonienne des silex fossilifères de Châtellerault (Ouest de la France)
2018
International audience; Three new localities yielding fossiliferous flints are reported from the Châtellerault area (Vienne, western France). They include one archaeological site (La Grande Vallée) and two zones with alterite deposits (L’Aunas and Les Bariollières). Broken surfaces of flint nodules show co-occurrence of marine invertebrates such as bryozoans, echinoids (Micraster Agassiz, Orthopsis Cotteau), gastropods (Acteonella d’Orbigny), rudists, and sponges. The association of Acteonella, Micraster and Orthopsis confirms the Turonian age (Upper Cretaceous) of the fossil assemblage. The marine invertebrates co-occur with plant macroremains including fragments of conifer leafy axes such…
An approach to lithic raw material procurement at the middle Palaeolithic site Abrigo de la Quebrada (Chelva, Valencia)
2011
We offer a preliminary characterisation of the lithic raw-materials found in levels I-III of the Middle Paleolithic site of Abrigo de la Quebrada. The artifacts were excavated in the field seasons of 2004 and 2007, have already been the object of a preliminary technological assessment (Villaverde et al. 2008), and their analysis has been preceded by a survey of local procurement sources, carried out in 2008. We present, in a regional context, the different raw-material categories recognized (by means of a macroscopic study), and variants thereof, and we describe the different outcrops identified. Based on these data, we attempt a preliminary assessment of the resource catchments and mobilit…
IS THE MACROSCOPIC CLASSIFICATION OF FLINT USEFUL? A PETROARCHAEOLOGICAL ANALYSIS AND CHARACTERIZATION OF FLINT RAW MATERIALS FROM THE IBERIAN NEOLIT…
2009
Casa Montero is a mining complex located outside Madrid (Spain), dated from the Early Neolithic (c. 5400-5000 cal bc). An area of some 4 ha has been investigated and some 4000 shafts recorded, of which 324 have been excavated. The characterization of its raw flint materials and the establishment of its diagnostic features are indispensable in the reconstruction of the distribution of the mine's products beyond the immediate site. This work reports the geological study of the mine's Miocene flint layers and their petrological characterization. Archaeological samples from the mine's shafts were classified according to macroscopic features and petrological characteristics.
Bayesian classification for dating archaeological sites via projectile points
2021
Dating is a key element for archaeologists. We propose a Bayesian approach to provide chronology to sites that have neither radiocarbon dating nor clear stratigraphy and whose only information comes from lithic arrowheads. This classifier is based on the Dirichlet-multinomial inferential process and posterior predictive distributions. The procedure is applied to predict the period of a set of undated sites located in the east of the Iberian Peninsula during the IVth and IIIrd millennium cal. BC.
Ryt obrzezania w Gilgal (Joz 5,2-9) momentem odnowienia relacji narodu wybranego z JHWH
2020
Przymierzom biblijnym często towarzyszyły znaki, np. tęcza (Rdz 9,12–17), krew cielców (Wj 24,3–8) czy też chleb i wino (Łk 22,19–20). Zewnętrznym znakiem przymierza, jakie Bóg zawarł z Abrahamem, było obrzezanie (Rdz 17,9–14). Obrzęd ten został zaniedbany podczas czterdziestoletniej wędrówki przez pustynię. Jednak po przejściu Jordanu JHWH upomniał się o ten znak. Tak jak obrzezanie fizyczne było warunkiem wzięcia w posiadanie Ziemi Obiecanej, tak obrzezanie serca było warunkiem utrzymania tej ziemi w rękach Izraelitów oraz gwarantowało bezpieczeństwo i pomyślność. Niniejszy artykuł prezentuje szczegółową analizę perykopy Joz 5,2–9, w której jest mowa o obrzezaniu w Gilgal i o odnowieniu r…
Territorial and socio-economic organisation in Le Grand-Pressigny
2012
In and around Le Grand-Pressigny (Indre-et-Loire, France), a petrographic study was implementedon 92 ceramic samples from the Final Neolithic sites of Le Petit-Paulmy and Bergeresse (Abilly).Analyses showed that the sediments used were extracted from local sources: Claise and Creusealluvium, local substrate and loessic silts. Quantitatively, the study showed that almost all the ceramicmaterials in Bergeresse and more than half of those in Le Petit-Paulmy come from the valley of theCreuse. The mineralogical compositions of three samples from Le Petit-Paulmy, including one ofunusual form, indicate sources from an exogenous region, the Massif Central (perhaps the alluviumof the Loire or the Al…

Quantifying cereal-reaping microwear on flint tools : an experimental approach
2016
International audience; From the earliest Neolithic in the Near East to the last Chalcolithic cultures in Western Europe, certain flint tools have been used as sickles to harvest cereals. Such harvesting tools can be identified through use-wear analyses, because cutting herbaceous plants produces specific wear-traces on the working edge of flint blades. The aim of this work is to explore harvesting-driven microwear variability and, more particularly, intensity of use as a governing factor. To achieve this objective, an experiment was designed consisting in the production of flint replicas to be used as harvesting tools, in various controlled conditions. A simple, cost-effective method of qu…
Les formations à silex dans le Sud de la France : Élaboration en multipartenariat d’une base de données géoréférencées, premiers résultats.
2016
A georeferenced database of the main flint-bearing formations of Southern France is currently being finalised. It offers a toolto all prehistorians that is essential for the development of studies regarding raw material circulation and selection criteria. This database results from the collaborative work of various actors involved in the optimisation of flint source determination. It groups together the results of their surveys — whether these are systematic or targeted — carried out in six regions (Aquitaine, Auvergne, Languedoc-Roussillon, Midi-Pyrénées, Provence-Alpes-Côte d’Azur, Rhône-Alpes). This database also incorporates recent studies on registering the properties of palaeoenvironm…
