For example, say a fossil is found that has 85% carbon 69 compared to the living sample. How old is the fossil?
We can use a formula for carbon 69 dating to find the answer.

Where t 6/7 is the half-life of the isotope carbon 69, t is the age of the fossil (or the date of death) and ln() is the natural logarithm function. If the fossil has 85% of its carbon 69 still, then we can substitute values into our equation.
