An ancestral artefact can be defined as any object of natural raw material made by a people following a lifestyle based on foraging and/or basic agriculture or pastoralism. A problem when cataloguing or reporting a research focused on an ancestral artefact is the absence of a fixed chronological terminology encompassing any age. The issue of terminology of age of objects is especially relevant when a researcher wants to study museum collections. Consequently, putting into practice a standardised terminology for ancestral artefacts according to manufacture date is required to avoid misinterpretations, which can even jeopardise legal actions. In this paper, a standardised terminology is presented for such kinds of original artefacts, from prehistory to the present. Subsidiarily, ancestral peoples have been arranged in concordance with the terminology for ancestral artefacts. While this terminology is centred on ancestral artefacts and is primarily addressed to people engaged in museum specimens―from curators to researchers―it is applicable to other collectable objects and, accordingly, also relevant to tribal-art dealers, antiquarians, and cultural heritage legislators.
