The above list is not exhaustive; most organic material is suitable so long as it is of sufficient age and has not mineralised - dinosaur bones are out as they no longer have any carbon left. It has been fundamental, especially in Europe, to demonstrating how landscapes are relics and monuments in themselves and are worthy of study as such. After this point, other Absolute Dating methods may be used. Radiocarbon dating is simply a measure of the level of 14 C isotope within the organic remains 8.
