“…Internal platform angle (IPA) is considered a slightly more important feature than the external platform angle (EPA) for the determination of knapping methods. Previous studies have called attention to the importance of angular relations between the platform and dorsal or ventral surfaces for the discrimination of knapping methods (Boëda 1993;Kelly 1954;Lenoir & Turq, 1995;Slimak 2003;Soriano & Villa 2017;Terradas 2003). In the experimental sample used in this study, Levallois products had IPAs with lower values than those of discoid or hierarchical discoid products, despite the inclusion of cortical elements.…”

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

“…In response to early suggestions that platform facetting should be an intrinsic part of the definition, Bordes (1950) used both archaeological and experimental evidence to argue that Levallois flakes could have unfacetted platforms (Schlanger 1996:250). This was further clarified by Kelley (1954), who conducted extensive refittings of Levallois assemblages from northern France and concluded that 'the most important question is not the presence or absence of facets, but rather the angle of the striking platform in relation to the splitting plane of the flake' (Kelley 1954:151 cited in Schlanger 1996. This view has subsequently been supported by a number of other workers (Delagnes 1995:201;Sellet 1995:33).…”

<p>An analysis of stone artefacts from the Arcadia Valley in south central Queensland is used to develop a core reduction sequence model for the region. During the initial construction of this model, core types are identified that reflect phases or end points in reduction trajectories. The model shows that core reduction methods employed in the Arcadia Valley during the mid-to-late Holocene included Levallois, discoidal, prismatic and burin blade core methods, along with less formal reduction strategies. In recognition of the equifinality of many reduction processes, the model has a flexible structure. Hence the prevalence of the various core reduction methods, and their relationships to each other, may be the subject of a range of hypothetical scenarios which can be tested by employing multiple lines of additional evidence. Following this procedure, it is concluded that Levallois and discoidal methods may account for close to half of the artefact assemblage, while less formal methods were also very common.</p>
