By contrast, methane created from petroleum showed no radiocarbon activity because of its age.

The results were summarized in a paper in Science in 1947, in which the authors commented that their results implied it would be possible to date materials containing carbon of organic origin.

The development of radiocarbon dating has had a profound impact on archaeology.

In addition to permitting more accurate dating within archaeological sites than previous methods, it allows comparison of dates of events across great distances.

It is based on the fact that radiocarbon ( in a sample from a dead plant or animal such as a piece of wood or a fragment of bone provides information that can be used to calculate when the animal or plant died.
