Malaga cove archaeological site carbon dating avg license not updating
The researchers found that certain soft tissues — notably blood, nails and hair — had radiocarbon levels identical to the contemporary atmosphere.Therefore, the radiocarbon level in those tissues post-mortem would indicate the year of death.Radiocarbon dating is a widely applied absolute dating method in archeology.
In contrast, from 1955 to 1963, atmospheric radiocarbon levels almost doubled.
Since then they have been dropping back toward natural levels.
The researchers found that year-of-death determinations based on nails were accurate to within three years.
The generally poor post-mortem preservation of soft tissues would be a limiting factor to this approach.
Unlike tooth enamel, soft tissues are constantly being made and remade during life.
