Despite recent advances in the identification of bipolar knapping, its role in many sites is not well known. We propose to assess the significance of this technique in the context of changes that occur in the Mesolithic. A lithic assemblage was recovered from unit SG at Font del Ros (Catalunya, Spain) in which pitted stones, cores and products arising from bipolar reduction (flakes, fragments and splintered pieces) were identified. This study indicates that the bipolar technique is fundamental in the settlement. These results are key to defining the organization of Holocene hunter-gatherer subsistence in northeast Iberia.
La renovación metodológica que ha surgido en los últimos años en el ámbito de la arqueología prehistórica ha favorecido la aparición de nuevas técnicas y estrategias de excavación que facilitan una mejor comprensión del registro arqueológico. Este volumen recopila una serie de textos que presentan diferentes aspectos metodológicos, cuyo objetivo es servir como introducción de los diferentes técnicas abordadas: geoarqueología, fitolitos, escáner 3D. El recorrido discurre desde la prospección arqueológica hasta las sistemáticas de excavación, repasando las diferentes metodologías que contribuyen a una mejor contextualización y preservación de los restos recuperados.
Core reduction provides insight into the technical actions involved in knapping sequences, one of the central elements in technological analysis. By examining reduction phases, cognitive and operational aspects of the management of lithic resources can be explored, and the technical behaviours of human groups reconstructed.This paper presents a technological and morphometric analysis of cores from the Magdalenian sequence of the Cova Gran de Santa Linya (SE Pyrenees), which ranges from 23 to 16 k cal BP. The knapping strategies suggest two types of lithic exploitation: one on nodules using semi-circumferential methods and the other on thick flakes using burin-core methods. Five knapping modalities were identified through the study of reduction sequences and the analysis of technical attributes, which highlights the technical diversity of lithic production systems.The data collected are supported by statistical analysis and reveal significant differences at the diachronic level and among the lithic assemblages. This study aims to suggest a reference model with which to characterise Magdalenian cores in technological terms. This model can broaden our understanding of the diversity of technical behaviours that appear from the beginning of LGM-b to the end of MIS 2 in the north-eastern Iberian Peninsula.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
