The half-life of C is approximately 5730 years, which is too short for this method to be used to date material millions of years old.
The isotope of Potassium-40, which has a half-life of 1.25 Billion years, can be used for such long measurements.

Edwards (2014) Stable Isotopic (d13C and d15N) Characterization of Key Faunal Resources from Norse Period Settlements in North Iceland. And how can these cases of the past be mobilized to serve modern efforts to secure a genuinely sustainable future? This book assembles a regional model through which the reader is presented with a vivid and detailed image of the climatic events and cultures which have occupied these seas and lands for roughly a 5000-year period.
The isotopes – variations of elements – found in the men's teeth show that they grew up in countries where the climate is colder than in Britain, with one individual thought to be from north of the Arctic Circle.
Over the following two months, Oxford Archaeology carefully removed the 51 decapitated skulls from the ground – which were placed in one distinct area of the pit – and the bodies discarded haphazardly in another area of the pit.
They were linked to the later discovery of the remains of a young male who, according to strontium isotope analysis, had spent his early years in Scandinavia.
