Why are fossils older than 60 000 years hard to date using C14? What will be an ideal response?
C14 has a half-life of just over 5000 years. With each half-life, half of the C14 present goes through
radioactive decay. By 60 000 years, the vast majority of the C14 is gone due to so many successive
half-lives. While theoretically some C14 remains, the amount would be insufficient to accurately date
the fossil.
