Les productions à caractère symbolique du site moustérien de La Roche-Cotard à Langeais (Indre-et-Loire, France) dans leur contexte géologique

Abstracts

La Roche-Cotard site is located on the right side of the Loire valley, about 20 km down-river from Tours. The site, uncovered in 1846, following the extraction of materials, was excavated in 1912. Research was taken up again from 1975 to 1978, then from 2008 onwards.
The first reprise of excavations in 1975 allowed for the discovery, at the entrance of a cave on a beach of the Loire on which Neanderthals have made fire, of stone tools and a proto-figurine that was named by M. Lorblanchet the “Mask of La Roche-Cotard” (Marquet & Lorblanchet, 2000, 2003). A very low shelter was also discovered, which contains some stone tools and a layout of blocks on the ground.
The second reprise of excavations in 2008 allowed for the discovery of a small cave-shelter filled with sediments, presenting also indications of occupation by Neanderthals; but above all it enabled further work on the inside of the main cavity.
Deeper examination of the cave walls, carried out by J.-C. Marquet, with the support of M. Lorblanchet, P. Paillet and E. Man-Estier, allowed for the recognition of three panels of finger flutings and a panel of point-marks. These marks are visible due to the removal of matter (by hand or with the aid of an instrument giving the same type of marks) on the weathered « tuffeau chalk » wall, recovered by a thin film of silty clay. On one of the panels can be observed a circular representation, on the other two, sets of parallel markings, organized and rhythmic. Four red ochre stains were also discovered.
Geometric, granulometric and morphologic studies of the deposits, as well as
14C datings of bones and datings of sediments through the OSL method, show that following the occupation by Neanderthals, the entrance to the cave was blotted out and was only reopened in 1846, or even in 1912.
No direct dating of the markings is possible. However, their localized weathering, datings of bones and sediments found just in front of the panels and naturally the closure of the cave’s entrance after the occupation by Neanderthals allows us to rule out the possibility of a recent age.
Mask, markings and traces of painting in a cavity inaccessible to
Homo sapiens until 1846, geometry of deposits, all add to the great interest in La Roche-Cotard site, at the very moment when we reconsider seriously the question of the competences of the Neanderthals.

1La Roche-Cotard (LRC) site is located by the town of Langeais in the Indre-et-Loire region, France. It develops halfway up the slope on the right bank of the Loire valley just upstream of the town and west of Cinq-Mars-la-Pile. It is therefore south-facing; it consists of a cave, a station at the foot of the cliff, a small very low shelter and a cave-shelter of small dimensions. It is not impossible that the knowledge we have today is incomplete due to its geological context and the very particular circumstances that led to the discovery. While a Mousterian layer yielded the mask of La Roche-Cotard, an object many experts now consider as a symbolic production of the Neanderthals, and as various recent discoveries are broadening the question of the skills of the predecessor of modern humans in Western Europe, it was appropriate to bring to the attention of the scientific community other productions from this site that will be considered here.

1 - History of the discovery and research on the site

2Until the mid-nineteenth century, and for a number of preceding millennia, the site was completely masked by slope deposits whose geometry can be known thanks to natural profiles visible a few hundred meters downstream and upstream of the site.

3In 1846, the construction of the railway line from Tours to Angers required huge amounts of materials that were taken from the foot of the valley slope, nearest to the part to elevate. Thus in the current park of La Roche-Cotard estate (fig. 1), large masses of sediment were removed, undermining the slope and advancing in various proportions toward the edge of the plateau. The entrance to the cave may have been opened but it was not really discovered then or, if it was, no interest was given to it by the workers who loaded the dirt carts.

4It is possibly because the cave is located within a fenced private estate that the real discovery was delayed. Indeed, François d’Achon, the owner, entered the cave in January 1912 (d’Achon 1913). With his workers, he excavated most of the content in a few weeks and found numerous bones and knapped flints (we will use the term flint for the siliceous material brought onto the site and knapped), especially at the entrance and in the first part of the cave.

5New research was undertaken in the 1970s, in three campaigns, in 1975, 1976 and 1977. Our aim was twofold: to identify the existence of remains of archaeological layers inside the cave and to carry out a survey pit at the entrance of the cave in search of possible intact occupation levels.

6The three excavation campaigns yielded extremely interesting results (Marquet, 1979, 1997) (fig. 2), which can be summarized as:

  • The discovery of fragments of layers, sometimes quite substantial, intact, in the F. d’Achon cave (LRC I);

  • The discovery of an intact Mousterian level in the excavation conducted in front of the entrance of the cave (LRC II); it is the latter that yielded the La Roche-Cotard mask;

  • Finally, the discovery, a little further east, of a low shelter (LRC III) filled with sediment (fig. 2).

7Between 1975 and 1977, little work was carried out inside the cave (LRC I) but we had already examined the walls. The existence of a very thin film of sediment was observed as well as the curious natural "withdrawal" of the wall from its base to a certain height, always constant in all the first half of the cave. Finally, the presence of traces of various kinds on the walls was noted, some of which appeared to have been made by fingers.

8From 2008, new research has revealed, further east, a small cave shelter masked by a 10 meter-high impressive succession of strata in LRC IV (Ajas 2011). They mostly helped to resume the study of the walls of the d’Achon cave and to do the tracing of a number of marks, the topic of the present paper. Two series of dating have also been carried out, one by the 14C method on bones and the other by the OSL (Optically Stimulated Luminescence) method on sandy sediments.

2 - The various stratigraphic sequences

9For the purpose of the demonstration we want to do here, crucial for the dating of the finger flutings, we will present two of the different stratigraphic sequences, LRC I and LRC IV.

2.1 - The stratigraphy of La Roche-Cotard I

10In 1912, François d’Achon with the help of his workers, emptied the cave in a few weeks to collect knapped flints and bones of large mammals (d’Achon ibid). In his publication, he gave a map of the cave indicating, roughly, the location of the different finds (fig. 3), with poor photographs of the excavated bones and knapped flints but, unfortunately, without stratigraphic section of the infill.

11When we resumed the excavations (1975-1977), a new map was done, which was taken up later by the topographical service of the Union of the Caves 37 (fig. 2) at the time of the 2008 excavations. We then excavated partly some remains of residual layers situated in altitude, and the sediments were analyzed.

12Today, we can consider that in the first part of the cave, the stratigraphy is broken down as follows (fig. 4):

  • A lower layer, whose thickness is difficult to assess due to the irregularity of the ground that rises very rapidly when one moves away from the entrance. It consists of very fine sandy sediment containing few bone fragments and lithic pieces of flint of very good quality for its capacity to be knapped and in excellent condition. This level has been dated by 14C in the Mousterian gallery to 38,060 ± 940 years (Lyon 7864) (table 1).

  • A thick middle layer composed of sediment, which has the characteristics of an overflow silt of the Loire (Macaire in Marquet 1997). It contained the remains of large mammals, bovines, equine, deer, etc. (Byrne, Delpech, Prat in Marquet 1997) very strongly influenced by the action of hyenas (broken and gnawed bones), but absolutely no lithic industry. It was dated by 14C to an age over or equal to 38,400 (Gif 4447) in an alcove in the entrance of the cave and to 43,000 ± 2,400 (Lyon 6961) in the Lemmings Chamber. A remain of the middle layer was also preserved from the extraction of materials in 1846 and from erosion as it is, outside of the cave, protected at the bottom of a relatively deep small niche. A sample taken for OSL dating method has enabled to unearth a bone, currently being dated, and a very good flint flake (not the local flint that is damaged by frost) and very fresh. The latter element shows that it comes from the base of this middle layer as it incorporated this flake from the lower layer containing Mousterian industry. The 14C dating of the bone is not yet known but the OSL method gives an age of 72,600 ± 6,000 years (MFGI Budapest) for the sediment in that niche;

  • An intact upper layer in very large remains that completely fills a corridor communicating between the Lemmings Chamber and the outside. One part is still in place and covers a remain of the middle layer; this set will be preserved. The nature of this layer is fundamentally different from that of the middle layer, very rich in cryoclastic elements; the fauna confirms a particularly cold climate episode while it was building up. A bone has been dated between 34,795 and 35,942 BC (Lyon 6962) by 14C and the sediment to 64,100 ± 5,100 (MFGI Budapest) by the OSL method. The difference between the dates obtained by the two methods comes from the fact that for almost all of the 14C dates in La Roche-Cotard, we are close to the limit of validity of the method;

13Next to these remains found near the outside of the cave, there were others, more distant from the entrance:

  • A 7 to 8 cm thick intact layer, not reached by d’Achon, in the northern part of the Chamber of the Pillar, is made of particularly compact clay that contained few rare angular fragments of bone, isolated teeth but also large amount of small fragments of cancellous bone. Only one knapped flint was found in this layer. The sediment is quite poor in pollen grains. A micromorphological blade shows the compactness of the sediment and the microstructure confirms that a significant packing has affected this layer dated to 47,500 ± 3,000 by 14C;

    • 6 Vernacular name given to this rock.

    In the last available space of the cave, the Hyena Chamber, a thick filling was partially excavated by F. d’Achon who has collected a large number of large mammals remains, broken and eaten by hyenas, as well as an almost complete hyena skull. An equine tooth, forgotten by d’Achon, was found resting on the hardened surface that terminates the infill while the survey pit in the underlying layers did not yield any object. This tooth has been dated to 44,600 ± 2,300 by the14C6.

2.2 - The stratigraphy of La Roche-Cotard IV

14The reopening of the excavation in 2008 was particularly motivated by the desire to continue a former test pit beyond La Roche-Cotard III, which had not reached the tuffeau chalk wall. A one meter wide trench then an excavation in a small cave-shelter discovered at the base of the wall helped to highlight a ten meters thick stratigraphy (fig. 5).

15The layers discovered are the result of various contributions: on the external side, some result from the overflowing of the Loire River (layers 10 and 11), others on the internal side are due to the dissolution of the limestone that form the substrate (layer 22) and, finally, the last ones, vertical and rich in frost-flaked plaques (layers 7-9) or mostly sandy-silt-clayey (layers 2-6) from the dismantling of the wall and the slope-washed layers from the plateau. Layer 22, the oldest, has been dated to 189,000 ± 14,900 years by the OSL method (MFGI Budapest). The layers of the middle part of the infill (c 12 and 13) have yielded some knapped flints, always very fresh and a few broken bones, sometimes burnt, rarely worked (incisions by flint, retouchers). Layer 12 has been dated by the OSL method to 86,200 ± 6,500 (MFGI Budapest), layers 13b and 13d of an age over 45,000 (Lyon 7862 and Lyon 7863). We shall return later to the interest of this thick filling.

OSL measurements were made using a Risø TL/OSL DA-15C/D automatic reader with a calibrated 90Sr/90Y beta source. Luminescence purity of the quartz extracts was checked using infrared stimulation. Blue light-emitting diodes (LEDs) were used for the optical stimulation of quartz for 40s, at 125ºC. A Single-Aliquot Regenerative-dose (SAR) protocol was used to estimate equivalent doses with illumination for 40s at 280º C in the last step of each cycle (Wintle and Murray, 2006). The additional last cycle was infrared and then blue stimulation with IRSL and OSL measurement respectively to monitor the purity of the quartz grains on each aliquot (Thamo-Bozso 2013). Measurements have been made by Dr. E. Thamo-Bozso, supervised by Dr. G. Turczi, reviewed by Dr. I. Kovacs and approved by Dr. T. Francsik, director in Budapest, 2013.

Title Table 1 - Langeais. Radiocarbon dating and by OSL method of levels of the four loci of the site Roche-Cotard.
Caption OSL measurements were made using a Risø TL/OSL DA-15C/D automatic reader with a calibrated 90Sr/90Y beta source. Luminescence purity of the quartz extracts was checked using infrared stimulation. Blue light-emitting diodes (LEDs) were used for the optical stimulation of quartz for 40s, at 125ºC. A Single-Aliquot Regenerative-dose (SAR) protocol was used to estimate equivalent doses with illumination for 40s at 280º C in the last step of each cycle (Wintle and Murray, 2006). The additional last cycle was infrared and then blue stimulation with IRSL and OSL measurement respectively to monitor the purity of the quartz grains on each aliquot (Thamo-Bozso 2013). Measurements have been made by Dr. E. Thamo-Bozso, supervised by Dr. G. Turczi, reviewed by Dr. I. Kovacs and approved by Dr. T. Francsik, director in Budapest, 2013.

Title Figure 22 - La Roche-Cotard I et IV. Correlation between the three main levels of LRC I with the deep levels of LRC IV.
Caption The two sections are situated with the same altitude scale. The simplified stratigraphic log of LRC II, LRC III and the boring of SRA/1995, have been also placed on the same scale; the levels with lithic industry of the two locus are at an altitude lightly higher than those of LRC IV. The mousterian level in the cave of LRC I is clearly above the three others.
