Many people assume that rocks are dated at “millions of years” based on radiocarbon (carbon-14) dating. But that’s not the case. The reason is simple. Carbon-14 can yield dates of only “thousands of years” before it all breaks down. The most well-known of all the radiometric dating methods is radiocarbon dating.
WebNov 20, 2024 · Carbon-14. Carbon-14 dating is a method, based on unprovable assumptions about the past, used to date things that contain carbon (e.g. fossils). It can only give maximum ages of around 50,000 … WebFirst, the relative age of a fossil can be determined.

WebA formula to calculate how old a sample is by carbon-14 dating is: t = [ ln (Nf/No) / (-0.693) ] x t1/2. where ln is the natural logarithm, Nf/No is the percent of carbon-14 in the sample compared to the amount in living tissue, and t1/2 is the half-life of carbon-14 (5,700 years). So, if you had a fossil that had 10 percent carbon-14 compared ...

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.
