Introduction During the Marine Isotope Stages MIS 5e3, Neanderthals had to face dramatic changes in climatic and environmental conditions, well documented in ice-core 18 marine-core pollen data, faunal remains from archaeological sites and geological signatures in sedimentary deposits. A comparison with other Mousterian sites showing similarities in the region is also presented. Layers 9e5 constitute one lithostratigraphic unit made of interbedded ashy deposits and clayey silts and are very rich in anthropic remains. The nature of the sediments and micromorphological features were studied by Couchoud and more recently by Golberg Regional map showing the location of the Roc de Marsal and other important Mousterian sites in Dordogne. It was made famous by the discovery of the skeleton of a Neanderthal child. Chronological results combined with palaeoenvironmental data efaunal remains and micro- morphological features in the sediments from the cave, pollen proxies and faunal remains from the region eallowed us to place climate variations in southwest France on a numerical time scale. Layers 7 and 9 yielded numerous combustion features and a high percentage of burnt lithics Sandgathe et al. Stratigraphic view of the Roc de Marsal sequence. Presentation of the site Roc de Marsal is a small cave located in southwest France Campagne, Dordogne. This collapse of the roof seems to have occurred during the Middle Palaeolithic, since Mousterian artefacts have been found above the blocks. A reappraisal of the stratig- raphy led to the distinction of seven major lithostratigraphic units and 13 archaeological layers, over a total thickness of between 1 and 2 m Fig. Lithic produc- tion also varied during the period spanning MIS 5e3 as seen in variations in the technology of blank production and in changes in the emphasis of certain retouched tool categories. Chase, ; Henrich, ;Stiner et Kuhn, ;Richerson et al. Interestingly, a faunal pattern showing a mix of red deer, roe deer and reindeer was found to have occurred during MIS 4, which was shown to be consistent with data from other similar sites in southwest France. These variations have led to the creation of the Mousterian techno-complexes including Denticulate Mousterian, Typical Mousterian, Quina Mousterian, and Mousterian of Acheulian tradition, among others. Ice segregation is particularly important in Layers 4e2, attesting to particularly cold climate conditions during or after deposition of these sediments Couchoud, ;Golberg, Excavations were carried out by an amateur, J. Later a new series of campaigns were undertaken by some of the present authors, between and , to re-explore the stratigraphy of the site and to re-assess the archaeological features of the Middle Palae- olithic occupations Turq et al. Lithic production has been attributed to: A roof fall involving a number of massive calcareous blocks occurred at some point, presumably during an intense cold period, separating recent from Palaeolithic artefacts Couchoud, This site documents changes in lithic production Denticu- late, Typical with a high Levallois index, and Quina Mousterian techno-complexes associated with important climatic changes, as attested to by analyses of faunal remains and sedimentary deposits. Finally, Layer 10 revealed very few lithics and faunal remains, whereas Fig. Layer 2 is made of metric to pluri- metric calcareous blocks corresponding to a massive collapse of Fig. The site is particularly rich in combustion features Goldberg et al. The aim of this paper is to a combine TL and OSL dating methods to determine a chronological scenario for the successive occupations of the cave; and b discuss this scenario in the context of two different environmental proxies as provided by faunal remains from the cave and independent regional reconstructions based on palynological studies of marine sediment cores. Thus far, in terms of chronology, only qualitative interpretations relating fauna to MIS have been proposed ehence the need for numerical chronological data.
