Carbon dating yields some of the most accurate results for aging samples around 50,000 years old, and can be as accurate as within a few decades of the exact year. Carbon dating uses the relative proportions of the carbon isotopes carbon-12 and carbon-14 that the fossil/sample contains to pinpoint an almost exact time.
