Radiocarbon dating has been used to date archaeological objects for many years. In forensic cases, radiocarbon dating can be used to test whether a human bone is ancient or modern because during the 1950s and 60s there was a huge spike in radiocarbon in the atmosphere due to nuclear testing.
What dating method is used for bones?
The dating methods that can be used for dating fossil bones and teeth consist of radiocarbon, U-series, ESR, and amino acid racemization (AAR).
How can bones be used in forensics?
Forensic anthropologists not only are able to determine at the site whether skeletal remains are human, but they also employ various methods to determine the gender, age at death, race, and height of the deceased. The human pelvis provides the most reliable means for determining the sex of skeletal remains.
How do you date skeletal remains?
The Carbon 14, or radiocarbon dating method is one of the best-known methods of dating human fossils and has been around since the late 1940s. The Carbon 14 (14C) dating method is a radiometric dating method. A radiometric dating uses the known rate of decay of radioactive isotopes to date an object.
Why is dating important in archaeology?
The dating of remains is essential in archaeology, in order to place finds in correct relation to one another, and to understand what was present in the experience of any human being at a given time and place. Inscribed objects sometimes bear an explicit date, or preserve the name of a dated individual.
Which bones best indicate gender?
However, the pelvis is the best sex-related skeletal indicator, because of distinct features adapted for childbearing. The skull also has features that can indicate sex, though slightly less reliably.
