- Carbon dating is somewhat accurate1. Scientists are able to determine what the ratio was during a specimen's lifetime by taking a carboniferous specimen of known age1. The most helpful calibration technique utilizes tree ring data to ensure accurate dates for the last 12,000 years and foraminifera and corals to extend the calibration out to 50,000 years2. The oldest dates that can be reliably measured by this process date to approximately 50,000 years ago, although special preparation methods occasionally make an accurate analysis of older samples possible3.

By taking a carboniferous specimen of known age (that is, a specimen which we are able to date with reasonable certainty through some archaeological means), scientists are able to determine what the ratio was during a specimen's lifetime.
