Knowing this and an estimated amount of carbon-14 in the organism while alive can be used to determine the age of the fossil.
For a website with a simple calculator that computes this for you, see is the half-life of carbon-14 (5,700 years).

This is the time it takes for half of the carbon-14 to decay.Answer: When organisms containing C-14 die, there is no further intake of Carbon 14, so the Carbon- 14 concentration slowly decreases as individual unstable Carbon- 14 decay back into stable Nitrogen -14 atoms. For example, if the organism had 100 grams of carbon-14 when it died, after 5730 years the fossil would have 50 grams of carbon-14.For other examples see Science Fair Tips on where Janice Van Cleave is the Science Fair expert!

PASADENA, CA—In hopes of better understanding a phenomenon that has vexed researchers for decades, hundreds of theoretical scientists have assembled at the California Institute of Technology for the 35th annual symposium on how gas nozzles know when a car’s tank is full, sources said Thursday.
