Gli ultimi Neandertal nella Grotta di Fumane

Le recenti campagne di scavo hanno permesso di chiarire alcuni aspetti della vita degli ultimi neandertaliani che hanno abitato la Lessinia

Considerazioni finali

La Grotta del Clusantin ha restituito, fino ad ora, dati sulle condizioni climatico-ambientali tra i 14.700 e 13.600 anni dal presente. La successione sedimentaria documenta principalmente processi di degradazione crioclastica della zona atriale con crolli ed esfoliazione del tetto della cavità. Lo studio dei micro mammiferi e quello antracologico forniscono evidenze di una foresta a pino silvestre, pino cembro, peccio e/o larice con anche aree aperte. Le attività di caccia dell’uomo sono documentate nel periodo estivo; vi è una netta prevalenza della predazione sulla popolazione di marmotte; la grotta viene collocata fra i campi stagionali nei quali l’attività di scheggiatura risulta finalizzata principalmente alla produzione di armi da getto

Out of the Cave and into the Light: Perspectives and Challenges of Radiocarbon Dating an Open-Air Aurignacian Site (Régismont-le-Haut, Mediterranean France)

International audienceThis article presents the methods and results regarding the radiocarbon (AMS) dating of the site of Régismont-le-Haut. This site is one of the very few well-preserved Aurignacian open-air sites in southern France. It is also one of the only Aurignacian sites in France and Europe, more generally, to have conserved evident features, including many in situ fire-related structures. We selected charcoal and bone from all the major occupation sectors excavated so far, as well as from others which were important for understanding site formation. Considering difficulties faced when comparing the lithic industry of a site located in a poorly documented area with those belonging to the Aquitaine basin, where the "classical" definition of the Aurignacian was outlined, dating was conducted to accurately place the site within this technocomplex's internal chronology. In total, 19 charcoals (identified to Pinus sp. or gymnosperm) and 3 bones were submitted for AMS radiocarbon dating, each to one of three laboratories. We implemented a strict charcoal screening protocol for radiometric dating that required genus-identified individual charcoals that were well-associated with the fire-related structures. Despite this careful selection , most of the charcoals and all of the bones contained insufficient carbon for dating. Of the 19 charcoal dates attempted, 5 produced dates, from two loci. All fall in the span between the Middle Aurignacian and the Recent Aurignacian (between around 32,500 and 28,000 uncalibrated 14 C BP). An older subset of the dates (32.5-32 ka BP, ca. 37.5-35.5 ka cal BP) appears to be the most reliable. These results represent the first AMS dates ever performed on an Aurignacian open-air site in the Mediterranean area. The dates are compared to other recently dated southwestern France sites to establish which ones might be useful for future detailed archaeological comparisons. They are also instructive from a methodological point of view, in order to better appreciate the resolution of radiocarbon in this context. The focus of this article is on presenting the dating work, especially the protocol used in the selection of samples, the laboratory methods used for obtaining the dates and the challenges faced at this site. Among these, the divergence of dates between loci contrasted with geomorphological and archaeological evidence, with the latter two strongly pointing to one living floor, and either a single occupation or a few very close in time. This forced a reassessment of the chronological dating evidence. This article serves to show the importance of multi-prong approaches to archaeological dating, comparing and contrasting both contextual evidence and actual dates

Microscopic Charcoal Signal in Archaeological Contexts

The recovery of archaeological wood charcoals from combustion features provides insights into the exploitation and use of wood fuel resources and past landscapes. The quality of our interpretation based on wood charcoals, however, depends on reliable information about the charcoal assemblages resulting from taphonomy. Charcoal is very fragile in comparison to other combustion residues such as burnt bones. In archaeological contexts, charcoal can easily be fragmented into small pieces (<0.25 mm) due to their fragile property. The investigation of small fragments and particles is particularly important for the interpretation of combustion residues when large pieces of charcoal are rare or apparently absent in archaeological sites, which is mainly true for many European Palaeolithic sites. Here, archaeologists get incomplete information when only the largest pieces and fragments are considered. In this chapter, we present a method for extracting and quantifying charcoal pieces, fragments, and particles. This approach can be considered as a strategy to minimize the impact of sample incompleteness and biases related to combustion residues in archaeological contexts. We further provide (1) a definition of what the charcoal signal means in an archaeological context; (2) an overview of taphonomy that causes charcoal fragmentation; (3) a review of charcoal sampling, extraction, observation and quantification protocols; (4) a manual (pictures and descriptions) for the observation of charcoal, from large pieces to the smallest particles; and (5) a discussion about why the charcoal signal is useful for archaeologists. By taking into account the consequences of taphonomy, the microscopic charcoal analysis in archaeological contexts provides a reliable assessment of firewood and fuel management practices and the related resilience of societies through time. The microscopic charcoal analysis can further offer additional information about the intensity of taphonomical processes and dating
