When archaeological bone material is poorly preserved there may not be enough surviving biological material left for the analysis to be reliable.

However, in cases where the bones are well preserved, the isotopic signatures are considered to be representative of the individual specimen (either human or animal) that is being studied.

Isotopic indicators of environment are most often investigated through the study of oxygen isotopes.

Isotope Analysis Methods In order to investigate stable isotopes from human and animal bones, a very small sample of bone is needed for the analysis.

Due to advances in accelerated mass spectrometry (AMS) a small sample which can range from 200 milligrams to 1gram of bone can be used.

The isotopes most widely studied to address these questions are Carbon-13 ( isotopes.

The exploration of isotopic identifiers of mobility, environment, and subsistence in the past also has contemporary relevance in that it can aid in informing policies relating to heritage protection, resource management and, sustainability and perhaps most significantly, help us to learn more about the remarkable ability of our own species to adapt and survive in any number of environmental and cultural circumstances.

These processes are carried out to extract the "pure" bone collagen from additional components that make up bone, such as lipids and proteins.
