Description :
This study examines the dichotomy that C 14 ages for noncollagenous fossils are underestimated, whereas ages for collagenous fossil bones are more accurate. There is a high probability that amino acids from poorly preserved fossils will date younger than the true age of the fossil and that the radiocarbon dates could be decreased by 2 000 to 9 000 yr or more. By existing AMS techniques, the measured ages would probably be Holocene, not Pleistocene.
