Radiocarbon dating

Measuring the amounts of nitrogen and carbon in small quantities of ancient bones before radiocarbon dating using elemental analysis is a way to quantify the amount of preserved collagen and the quantity of exogenous contaminating carbon. Such a measurement can be performed on a large number of samples and allows to sort out the specimens with the best preserved collagen, those with the most carbon contamination, and eventually to infer relationships between burial conditions and collagen preservation. This approach is most interesting as a preliminary method to use before attempting radiocarbon dating using accelerator mass spectrometry of bone collagen. Journal page Archives Contents list. Lumley H.

Radiocarbon dating also referred to as carbon dating or carbon dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon , a radioactive isotope of carbon. The method was developed in the late s by Willard Libby , who received the Nobel Prize in Chemistry for his work in It is based on the fact that radiocarbon 14 C is constantly being created in the atmosphere by the interaction of cosmic rays with atmospheric nitrogen. The resulting 14 C combines with atmospheric oxygen to form radioactive carbon dioxide , which is incorporated into plants by photosynthesis ; animals then acquire 14 C by eating the plants.

The direct radiocarbon date makes it the oldest directly dated European Neandertal specimen, even though others have securely associated radiocarbon dates in the same time range. The stable isotopes are similar to those for other OIS 3 European Neandertals and indicate a relatively high trophic level for this individual. CalPal version 1.
