Cardoso, João Luis2025-06-112025-06-112025-05http://hdl.handle.net/10400.2/19937The issue of pre-Acheulean archaic industries, or, to use more rigorous terminology, the Oldowan (name derived from the Oldowan Gorge in Tanzania), has a long history in Portuguese territory, with some of the findings made so far being somewhat uncertain, given the lack of radiometric dating of the respective sediments and of coeval fauna, which could contribute to establishing the chronology of the geological formations in question, which have not been preserved due to the geochemical nature of the terrain. The following paragraphs will present a summary of the knowledge, identifying the main sites and associated artefacts, which constitute relevant elements for the critical analysis of the issue, based on the available observational data.porPré-históriaPré-AcheulenseOlduvaienseQuaternárioPortugalPrehistoryPre-AcheuleanOldowanQuaternaryjournal article
