Question 9 • LVA-Earth and Space Science - FALL

Carbon-14 has a half life of about 5700 years. How useful is it in dating ancient fossils?

Answer

Answer:

Carbon-14 is useful for dating relatively recent fossils, generally up to about 50,000–60,000 years old. It is not useful for fossils that are millions of years old because nearly all the carbon-14 has decayed.
