Radiometric dating and carbon dating of fossils
This half life is a relatively small number, which means that carbon 14 dating is not particularly helpful for very recent deaths and deaths more than 50,000 years ago.
After 5,730 years, the amount of carbon 14 left in the body is half of the original amount.
So, the fossil is 8,680 years old, meaning the living organism died 8,680 years ago.
Few fossils are thought to be younger than 57,000 years. All other forms of radioactive dating are based on the radioactive decay of igneous rocks.
