Carbon normally occurs as Carbon-12, but radioactive Carbon-14 may sometimes be formed in the outer atmosphere as Nitrogen-14 undergoes cosmic ray bombardment.

A further example from a lava flow off the coast of Hawaii shows similar discrepancies.

If dated with the carbon-14 method, the flow appears to be less than 17,000 years old, but dating with the potassium argon method gives dates of 160,000 to 43 million years.

But, carbon dating can't be used to date either rocks or fossils.

It is only useful for once-living things which still contain carbon, like flesh or bone or wood.
