Carbon dating accurate not
- At Oak Ridge National Laboratory, Scientists dated dinosaur bones using the Carbon dating method.
The age they came back with was only a few thousand years old. And kept their theory that dinosaurs lived "millions of years ago" instead. They then use potassium argon, or other methods, and date the fossils again.
In the following article, some of the most common misunderstandings regarding radiocarbon dating are addressed, and corrective, up-to-date scientific creationist thought is provided where appropriate. Radiocarbon is used to date the age of rocks, which enables scientists to date the age of the earth.
Radiocarbon is not used to date the age of rocks or to determine the age of the earth.
But now that we know that, we can actually correct carbon-14 dates for that source of error.
Many people are under the false impression that carbon dating proves that dinosaurs and other extinct animals lived millions of years ago.
Comparison of ancient, historically dated artifacts (from Egypt, for example) with their radiocarbon dates has revealed that radiocarbon years and calendar years are not the same even for the last 5,000 calendar years.
Basically, we've been using items of known age to check the accuracy of carbon dating ever since the method was invented in the late 1940s.
The short version is that, when 14C dating was developed in 1949, the first test of the method was to date Egyptian artifacts whose ages were already known from the inscriptions associated with them —plus to date some wood from old trees whose rings could be counted and the age of the wood known.
Libby's updated version of the "Curve of the Knowns", with some added data points, looked like this: You'll note that while the fit is still close, not every data point falls exactly on the curve.
The dots represent how much radioactivity was left in each actual artifact. That means that the amount of radioactivity from carbon-14 will give a very good estimate of a sample's actual age.

It is imperative to remember that the material must have been alive at one point to absorb the carbon, meaning that carbon dating of rocks or other inorganic objects is nothing more than inaccurate guesswork.
