    Microscopic Use-Wear Evidence for an Itaparica Uniface as a Hafted Multifunctional Tool
    (Taylor & Francis, 2025-01-01)
    This report presents the results of a microscopic use-wear analysis on a unifacial tool from an Itaparica-like context at the Toca dos Coqueiros site, in Serra da Capivara National Park, Northeastern Brazil. The analysis focuses on evidence of hafting and multifunctionality. These artifacts, found in central and northeastern Brazil from the late Pleistocene to the early Holocene, are associated with the Itaparica technocomplex. We present evidence of butchery, ochre processing, and hafting with resin residues, suggesting complex hafting systems. Functional hypotheses are proposed based on microscopic and macroscopic observations.

    De la forma a la estructura en tecnología lítica: una nueva metodología para los Andes Centrales (Perú)
    (Pontificia Universidad Católica del Perú, 2025-05-07)
    This article presents a methodology for the technostructural analysis of carved lithic artifacts that aims to understand how tools were used in the past. The proposal is based on the premise that all tools are a threefold structured system that comprises three parts: transformative, prehensility and energy reception. An artifact belonging to the lithic assemblage recovered at the site of Vadopampa in Ayacucho, Peru, has been analysed with the help of students as an example of the application of the technostructural approach. The paper thus introduces a new methodology for the Central Andes in a didactic and critical way, promotes a dynamic perspective for lithic tools, and assesses the potential and the limits of all technological interpretations.

    3D modeling as a tool for Paiján artifact preservation, dissemination, and analysis
    (Elsevier BV, 2025-06-01)
    Paiján lithic studies have provided significant insights into the technological behaviors of hunter-gatherer groups in the Andean region during the Late Pleistocene-Early Holocene. Over decades, research has predominantly relied on typological, technological, and experimental approaches. While valuable, these methods often lack quantification, replicability, and are heavily influenced by analysts’ experience and intuition. Estimating volumes, angles, convexities, and cross-sections remains challenging and subjective. This study evaluates the potential of 3D tools to address these limitations. We applied 3D and documentation techniques to a lithic sample from Quebrada Santo Domingo (Laredo, Trujillo) in the subtropical desert of the lower Moche Valley, northern Peru. These artifacts face destruction due to industrial and urban expansion, underscoring the urgency of their preservation. Our findings demonstrate the utility of 3D analysis in enhancing the accuracy of shape and geometry assessments while supporting digital preservation and enabling broader, more objective dissemination of archaeological data.
