Assessing the function of trapezoidal bitruncations from Beg-er-Vil (Quiberon, France) through the use-wear analysis
Résumé
Trapezoidal bitruncations are one of the most characteristic lithic elements of the Late Mesolithic of Brittany (France). Technological and typological studies of these elements show wide-ranging variability over time and space, but from a functional point of view, they are generally interpreted as transverse arrowheads. This hypothesis is based on evidence found in archaeological contexts where perishable materials are preserved, as well as on use-wear analysis. Previous experimental studies aiming to evaluate the functionality of these projectiles have provided significant information on hunting activities. However, many aspects associated with the use of these arrowheads remain open to debate. In order to contribute new data to the discussion, we carried out an analytical experimentation. A collection of trapezoidal bitruncations was reproduced and armed as transverse arrowheads. The latter were then shot against different targets to simulate a hunting situation in order to evaluate their functionality. Furthermore, we conducted a trampling experiment to recreate taphonomic wears posterior to the abandon of the trapezoidal bitruncations. The information obtained through this experimental approach was used to interpret the trapezoidal bitruncations from Beg-er-Vil (Quiberon, France), and then to discuss hunting strategies during the Late Mesolithic in Brittany. The overlap between the archaeological and experimental results allows us to demonstrate the use of transverse arrowheads in this site and provides new data and hypotheses for further discussion.
