What lies in between: Levallois, discoid and intermediate methods

Lithic artefacts are usually associated with the different knapping methods used in their production. Flakes exhibit metric and technological features representative of flaking method to detach them. However, lithic production is a dynamic process which discrete can be blurred, vary throughout process. An intermediate between discoid Levallois commonly referred under an umbrella terms (the present research uses term hierarchical discoid), broad geographical chronological distribution Early Middle Palaeolithic. This strategy exhibits both methods, raising question extent flakes from three differentiated and, when one mistaken for another, direction confusion. experimental assemblage detached by means was along attribute analysis machine learning models effort identify employed. In general, our results were able very effectively differentiate support vector polynomial kernel used. Our also underscored singularity reduction sequences, yielded outstanding identification values, rarely erroneously attributed either other two studied. Mistaking products most common confusion, although good value achieved acceptable flakes. shows potential applicability combination these among
