In organic material, after waiting 5568 years (the half-life of in the EPD Dating tables), and consisting of bulk sediments.

Thanks to fossil fuel emissions, though, the method used to date these famous artifacts may be in for a change.Radiocarbon dating (usually referred to simply as carbon-14 dating) is a radiometric dating method.It uses the naturally occurring radioisotope carbon-14 (14C) to estimate the age of carbon-bearing materials up to about 58,000 to 62,000 years old. Carbon-14 has a relatively short half-life of 5,730 years, meaning that the fraction of carbon-14 in a sample is halved over the course of 5,730 years due to radioactive decay to nitrogen-14.It occurs only in trace amounts, but it is present in every living thing.Carbon-14 can combine with oxygen in the atmosphere to create carbon dioxide, which is then absorbed by plants and makes its way through the food chain.
