Is carbon dating really reliable Liveerotik sex cams
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".
(Specifically, neutrons hit nitrogen-14 atoms and transmute them to carbon.) Land plants, such as trees, get their carbon from carbon dioxide in the air. The same is true of any creature that gets its carbon by eating such plants. Suppose such a creature dies, and the body is preserved.
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.
When this was first done, it turned out that carbon dating had been giving too-young dates for early civilizations.
Apparently, the production of C14 by the Sun has changed by several percent across the last 10,000 years.

If you hear of a living tree being dated as a thousand years old, that is not necessarily an example of an incorrect dating. Wood taken from the innermost ring really is as old as the tree. We can date things for which historians know a "right answer".
