WebApr 16, 2024 · Relative dating is used to determine a fossils approximate age by comparing it to similar rocks and fossils of known ages. Absolute dating is used to determine a precise age of a fossil by using radiometric dating to measure the decay of isotopes, either within the fossil or more often the rocks associated with it. WebThe approximate age of ancient artifacts can be determined as long as the artifact is not older than 50,000 years. It’s a technique called carbon-14 dating. All organisms that live on the Earth are based on carbon. This would be wood, plants, animals and of course humans.
