At least three farmsteads were discovered on the site and flints, which form a small assemblage suitable for the study of so-called simple productions. Indeed, the status of these productions remains unclear, both their nature and the modalities of their production. Estimating the level of expertise needed to produce these flints is particularly important in this context.
Furthermore, the debitage can look intentionally 'neglected' due to the simple multidirectional operations or the use of successive unipolar sequences. More recently, work conducted by Miguel Biard and Caroline Riche Inrap has focused on the use of flint hammerstones to produce flakes. These tools leave clumsy marks that are sometimes interpreted as maladroitness.
However, the authors argue that the technical knowledge of the knappers is less rudimentary than previously thought, even though the discussion is ongoing. This raises the question of the status of knappers in charge of these productions. This disconnection between 'complex' productions requiring high levels of skill and a certain degree of artisanal specialization and domestic simple productions seems to be a model that finds success during the Middle Neolithic.
The detailed study presented here includes the development of a method that highlights the objectives and the modalities of these productions.
This method uses two main elements: morphometric analysis and diacritical sketches. The morphometric analysis of the flake tools and negatives of removal of cores and facetted pieces involves comparing the dimensions of the tools to the removal negatives, with the result of several facetted pieces being isolated as it was not possible to provide the corresponding sized flakes to the flake tools.
