摘要：

AMS C-14 values have been obtained on collagen and osteocalcin fractions in a suite of modern, Holocene and late Pleistocene bone samples of varying collagen content. These studies were undertaken to examine the accuracy of C-14 age determinations on osteocalcin in bone samples where collagen and collagen-derived organic products are retained in significantly reduced concentrations. In a series of bones of assumed similar age, large discordances in the C-14 values of the osteocalcin and collagen fractions are observed. For the samples we have examined, these discordances are always associated with reduced concentrations of collagen contained in the bones.
