Other methods of anthropological dating

Relative dating methods rely on understanding the way in which physical processes in nature leave a record that can be ordered.Once the record of events is ordered, each event is known to be older or younger than each other event.Typically, a Master's Degree in chemistry is required because of the extensive lab work.Increasingly though, students are learning about the principles of radiocarbon dates in archaeology, palaeontology and climate science degrees and can combine cross-disciplinary studies.

Willard Libby would receive a Nobel Prize for Chemistry in 1960.

The next big step in the radiocarbon dating method would be Accelerated Mass Spectrometry which was developed in the late 1980s and published its first results in 1994 (3).

This was a giant leap forward in that it offered far more accurate dates for a far smaller sample (9); this made destruction of samples a far less delicate issue to researchers, especially on artefacts such as The Shroud of Turin for which accurate dates were now possible without damaging a significant part of the artefact.

The other two isotopes in comparison are more common than carbon-14 in the atmosphere but increase with the burning of fossil fuels making them less reliable for study (2); carbon-14 also increases, but its relative rarity means its increase is negligible. After this point, other Absolute Dating methods may be used.

Today, the radiocarbon-14 dating method is used extensively in environmental sciences and in human sciences such as archaeology and anthropology.Archaeologists had used Relative Dating methods to calculate their reigns.
