My research interest in this project is to develop methodology for accurate 14C dating on organic remains, (e.g., wood, charcoal, collagen, sediments) and inorganic carbon (e.g., ostrich egg shell, marine and terrestrial animal shells, and tooth enamel apatite). For the archeological chronologies including the Middle Stone Age, which are near the 14C dating limits, high-temperature pyrolysis technology is developed to convert organic remains into the graphitic-like carbon forms. The graphitic-like carbon is the most resistant to weathering and least likely to be contaminated by active or inert carbon sources. The high-temperature pyrolysis pretreatment on organic remains provides the most reliable 14C dates for older than 45,000 years BP. Students interested in this topic will study 14C dating in my lab, and these results are critical for understanding when these foragers lived in East Africa.
