What is Carbon 14 Dating? What is it used for?
Carbon-14 dating is process of determining the age of archaeological artifacts.
Carbon-14 dating is used for determining the age of certain archaeological artifacts of biological origin (could be bone, fiber, wood, plant remnants etc.) up to about 50,000 years old.
If a fossil has say 25% of carbon-14 as compared to living sample than it is 11460 years old (as it has one-fourth carbon it is 5730*2=11460 years old).
