Radiometric dating isotopes
The age of the carbon in the rock is different from that of the carbon in the air and makes carbon dating data for those organisms inaccurate under the assumptions normally used for carbon dating.This restriction extends to animals that consume seafood in their diet.This has to do with figuring out the age of ancient things.
Each isotope is identified with what is called a ‘mass number’.
It might take a millisecond, or it might take a century. But if you have a large enough sample, a pattern begins to emerge.
