Les Fieux (Lot, France) Paleolithic levels, report of the new studies

Archaeological researches have been conducted on Les Fieux site since 1967. Most of them remained un-

published, which explains that the site is still unknown even if it delivered an exceptional stratigraphical

sequence including Mousterian, Aurignacian, Gravettian and Sauveterrian levels. The site is currently ar-

ranged to be opened to public. Since 2006, a new eldwork program allowed a multidisciplinary team to

relaunch the study of the Paleolithic sequence with a view to a monographic publication.

The main results include a precision of the geomorphological framework, a renewed geoarcheological study

of the sequence, a dating program having already made it possible to clarify the age of the Gravettian levels,

a general archeozoological study of the fauna and an up-to-date study of the microfauna, the avifauna, the

ichtyofauna, the Neandertal human remains and a part of the lithic industry.

The First Results of Chronostratigraphic Revision of the Palaeolithic Sequence from the Kůlna

Cave (Moravian Karst, Czech Republic).

Since 2011 Anthropos Institute of Moravian Museum is applicant of the new grant project focused on the

revision and reconstruction of chronostratigraphic model of the Kůlna Cave.

A detailed determination of the chronological position of Micoquian layers in the Kůlna Cave has recently

become a key question in the transition of the Middle/Upper Palaeolithic in Moravia, especially from the

point of view of the possible chronological overlapping of the Upper Micoquian, the Lower Szeletian and

the Bohunician (cf. Neruda – Nerudová in press). The current dating of the Upper Micoquian occupation

in Moravia is based mainly on data from the Kůlna Cave. In the context of chronostratigraphic conception

made by Karel Valoch (1988) and its possible relation to the model of marine isotope stages recently pub-

lished by P. Neruda (Neruda et al. 2011) looked existing data well. We supposed layer 7a is well dated be-

cause both calibrated

C and ESR data t together and place the occupation to the period about 50,000 years

cal BP. Close dataset of ESR data we have obtained also for layer 9b that can be correlated with the period

of the lower Vistula Glaciation around 69 kyr BP (Rink et al. 1996). Position of both layers 7c and 11 has

been still unclear because data fall to excessively wide time range (for layer 7c) or they are too young for

layer 11. Unfortunately the new OSL data also vary too much and cannot be used for the correlation (Nej-

man et al. 2011).

In 2007 the problem of dating became more complicated because we obtained the

C date (52,700 ± 2,300

uncal. BP) for layer 6a. Such position is older in uncalibrated value then calibrated samples from layer 7a

(Neruda et al. 2011) and it indicate the overlapping of results for distinct horizons.

Solving the problem of dating of Palaeolithic horizons we should take into account also stratigraphy of the

cave. Layer 7a is relatively easy distinguishable but the uppermost Micoquian layer 6a in the entrance of the

cave is situated in the same sediment with limestone blocs as the oldest Magdalenian layer 6. Even the

Gravettian replace was found in the same horizon. It means it was only possible to distinguish archaeo-

logical nds in most cases but correlation of animal bones with a particular layer was rather unlike. Sedi-

ments represented Pleistocene – Holocene transition were preserved only in several spot in the cave and

usually they were disturbed by older excavation.

For these reasons selection of samples looks the most important task. The well controlled position of sam-

ples was the rst rule we applied (Davies – Nerudová 2009). We decided to use hard animal materials col-

lected in the framework of the excavation made by K. Valoch from 1961 to 1976. He gradually excavated

individual sectors in the entrance and in the inner part of the cave. Sometime the correlation of sediments

between the sectors was difcult because both morphology and character of sediments were affected by

post-depositional processes. For this reason a number of archaeological sub-horizons were distinguished

like 7a1, 6b or 7α, but according to K. Valoch it is possible to join together nds from horizons 7a and 7a1,

6a and 6b and 7c and 7α.

First we reconstructed the spatial distribution of archaeological layers essential for our project. The intact

sediments with layers 3, 4 and 5 (both Epimagdalenian and Magdalenian) have been presented only in the

entrance of the cave because the inner part of the cave has been modied during the 2

world war. Older
