Artefacts or Geofacts? The role of experimentation and functional analysis in the determination of tooles at Pleistocene sites in Serra da Capivara (Piauí, Brasil)

Abstract

[ES] La experimentación es básica para la aplicación del método traceológico y el análisis funcional es fundamental para conocer las actividades productivas realizadas con los instrumentos de trabajo prehistóricos. La presencia de rastros de uso permite confirmar el origen antrópico de los artefactos al clasificarlos como instrumentos. En este trabajo presentamos la experimentación llevada a cabo con réplicas de instrumentos en cuarzo de la Sierra de Capivara (Piauí, Brasil) y recuperados en sitios con dataciones muy antiguas para el continente americano. La controversia sobre el origen de estos artefactos llega hasta el día de hoy: ¿artefactos o ecofactos? Los trabajos que está desarrollando la Misión Franco-Brasileña en Piaui desde el año 2008, bajo la dirección de Eric Boëda, aportó nuevos datos principalmente en las dataciones y en el estudio de estos artefactos desde una perspectiva tecno-morfológica. Sin embargo, la identificación de rastros de uso en las superficies de estos artefactos similares a las conseguidas experimentalmente, nos ha permitido también reafirmar el origen antrópico de esos artefactos ya que fueron utilizados como instrumentos de producción.

[EN] Experimentation is basic in traceological methodology, and functional analysis is fundamental to determine the productive activities carried out with prehistoric tools. The presence of use-traces can confirm the anthropic origin of artefacts and classify them as tools. This paper presents the experiments carried out with replicas of the quartz implements found at sites in Serra da Capivara (Piauí, Brazil), with very old dates in the South American context. Controversy over the origin of these artefacts still rages: are they artefacts or geofacts? Research carried out at the Franco-Brazilian Mission in Piauí since 2008 under the direction of Eric Boëda has provided new data, mainly in the form of dates and the study of these artefacts from a techno-morphological perspective. The identification of similar use-wears traits on the surfaces of these artefacts to those produced experimentally confirms the anthropic origin of these artefacts and their use as tools.
