An Upper Aurignacien level located on a hilltop flat surface has been found at Combemenue (Brignac-la-Plaine, Corrèze, France) during field surveys along the A89 highway. Geomorphological evidence, and particularly the shallow depth of the level, strongly suggests that it has undergone significant perturbation due to a long-lasting exposure to sedimentary and pedological processes at soil surface or subsurface. Therefore, a detailled taphonomic study has been made to evaluate the impact of natural processes in site patterning. It involves examination of the spatial distribution of the artefacts, their orientation and dip (fabric), their size distribution, their alteration and refits. The results have been compared to the data derived from t...
