However, my own experience indicates that there is a lack of understanding of what, specifically, is being measured from samples; what is involved in the atmosphere-to-biosphere production, retention, and decay of radiocarbon; and what should and should not be dated from archaeological deposits using radiocarbon dating techniques.

Therefore, I will introduce the topic with a brief summary suitable for advanced students and archaeological professionals..

Like all continents, Africa has a heterogeneous geography and should not be viewed as a single “place.” However, in the context of this review, it will become obvious that there are issues unique to radiocarbon dating in Africa that overlap other areas of the world, but combine to create circumstances specific to the continent given the history of research conducted therein.

Interested readers are urged to read more general reviews of radiocarbon dating, which discuss issues more exhaustively and globally (e.g., Bronk Ramsey ).

However, a precise estimate of the age of an artifact (e.g., 10,000 ± 10 years before present []) is worthless if the sample is contaminated or has moved from its primary context, compromising its accuracy.

This review article will focus specifically on potential sources of error and critical evaluation of radiocarbon dates .

Accuracy refers to how close the assessed age of a sample is to the true age.

Gas proportional counting was developed later, involving the combustion of organic matter into methane (CH).

The application of radiocarbon dating to determine the geochronology of archaeological sites is ubiquitous across the African continent.

Accelerator mass spectrometry has made radiocarbon dating the most precise method to determine the death of living organisms that occurred within the last 50,000 years.

Egalement, les âges radiocarbone de calibration, issue de périodes critiques de la préhistoire africaine, manque la précision nécessaire pour résoudre des débats importants.

Une stratégie de datation multiple et une sélection rigoureuse des matériaux d’échantillons de radiocarbone sont conseillées dès les premières étapes de la conception de la recherche.
