Use the carbon dating method if the fossil is less than 75,000 years old. This method only works on young fossils as carbon decays quicker than other minerals. If no traces of carbon are found in a fossil, this indicates that it is older than 100,000 years. Use an accelerator mass spectrometer to measure the amount of carbon in the fossil. chubby burgers steinway
