The aim is to determine the suitability of inorganic carbon sources in fossil bone for accurate radiocarbon dating.
Three fossil bone samples of known age were analyzed for their carbon content.
Samples were hydrolyzed in acetic acid followed by hydrochloric acid for selective separation.
Dates on collagen-bone apatite pairs were compared for validation.
Calcium carbonate in fossil bone was found to be secondary.
Indigenous carbonate from bone apatite showed potential for accurate dating.
Increased agreement in dates between collagen and bone apatite pairs raised confidence in the dating method.
