When they die, they stop exchanging carbon with the biosphere and their carbon 14 content then starts to decrease at a rate determined by the law of radioactive decay.

Radiocarbon dating is essentially a method designed to measure residual radioactivity.

It is rapidly oxidized in air to form carbon dioxide and enters the global carbon cycle.

It’s often much easier to date volcanic rocks than the fossils themselves or the sedimentary rocks they are found in.

An age could be estimated by measuring the amount of carbon-14 present in the sample and comparing this against an internationally used reference standard.
