The carbon14 decays with its halflife of 5700 years while the amount of carbon12 remains constant in the sample by looking at the ratio of carbon12 to carbon14 in the sample and comparing it to the ratio in a living organism it is possible to determine the age of a formerly living thing fairly precisely.
If you have a fossil you can tell how old it is by the carbon 14 dating method this is a formula which helps you to date a fossil by its carbon if a fossil contains 60 of its original carbon how old is the fossil the half life of carbon 14 is 5600 years that means this is.
Carbon dating is used to determine the age of biological artifacts carbon14 radiometric dating and index fossils carbon dating is used to determine the age of biological artifacts up to 50000 years old.
By comparing this ratio to the halflife logarithmic scale of the parent isotope they are able to find the age of the rock or fossil in question isotopes used for dating there are several common radioactive isotopes that are used for dating rocks artifacts and fossils.

Span classnews_dtfeb 26 2008spannbsp018332best answer radiocarbon dating is a radiometric dating method that uses the naturally occurring isotope carbon14 14c to determine the age of carbonaceous materials up to about 60000 years plants fix atmospheric carbon during photosynthesis so the level of c14 in living plants and animals equals the level of c14 in the atmosphere.
For biological objects older than 50000 years scientists use radioactive dating to determine the age of rocks surrounding where the material was found by dating rocks scientists can approximate ages of very old fossils bones and teeth.
Absolute ages of rocks which kind of carbon dating can be used to determine the exact age of the rock and which kind of carbon dating is used to compare the ages of rocks radiocarbon dating is used to measure the age of fossils true or false true absolute age age in years of a rock or other object can be determined by using.
