Solutrean laurel leaf production at Maîtreaux: an experimental approach guided by techno-economic analysis
Résumé
Large-sized Solutrean laurel leaf typology has been defined on the basis of the exceptional pieces found at Volgu, France, in 1874. The geographical distribution of this rare type of large bifacial piece is limited to the border of the French Massif Central. Located at the northern limit of this distribution area, the Maıˆ treaux site provides new data on the reduction schemes of these pieces. Refitted sequences indicate that the Solutrean presence was motivated by the exploitation of local flint resources to produce reserves of lithic tools and/or blanks, elements for composite projectiles and preforms for exportation and later finishing and use/retouch elsewhere. Results of technoeconomic and spatial analyses are compared with those of an experimental project, mostly centred on laurel leaf techno-economy. This integrated experimental approach strongly contributes to the on-going social interpretation of the Maıˆ treaux group, allowing us better to characterize and quantify the remains of laurel leaf reduction processes. Also produced were in situ ‘undisturbed' knapping features for taphonomic reference and interpretation. At the site scale, experimental work coupled with spatial and techno-economic analysis is relevant for the interpretation of different geoarchaeological, technical and social aspects of the archaeological record. At a regional scale, experimental work on the available raw materials in each geographic zone is required to clarify issues related to raw-material procurement, exploitation and circulation, such as regional lithic resource exploitation strategies and inter-site discontinuities of production.
