Radiocarbon dating of fossils
As the name suggests, fossil fuel is old, and no longer contains C14.
Both of these man-made changes are a nuisance to carbon dating.
If you hear of a carbon dating up in the millions of years, you're hearing a confused report. Second, they rarely contain any of the original carbon.
"If we reduced fossil fuel emissions, it would be good news for radiocarbon dating," said the study's author, Dr Heather Graven from the Department of Physics and the Grantham Institute -- Climate Change and Environment at Imperial College London.Historians don't have "right answers" for really old things.However, carbon dating has done well on young material like the Dead Sea Scrolls, the Minoan ruins, and acacia wood from the tomb of the pharoah Zoser.In short, unless you have evidence to the contrary, you should assume that most of the carbon in a fossil is from contamination, and is not originally part of the fossil. The nuclear tests of the 1950's created a lot of C14.Also, humans are now burning large amounts of "fossil fuel".
