Other radioactive isotopes are also used to date fossils the halflife for 14 c is approximately 5700 years therefore the 14 c isotope is only useful for dating fossils up to about 50000 years old.

Radiocarbon dating also referred to as carbon dating or carbon14 dating is a method for determining the age of an object containing organic material by using the properties of radiocarbon a radioactive isotope of carbon the method was developed in the late 1940s by willard libby who received the nobel prize in chemistry for his work in 1960.

Carbon14 dating can determine the age of an artifact that is up to 40000 years old living organisms absorb carbon my eating and breathing after burning a small piece of an artifact scientists compare the amount of carbon14 to the amount of carbon12 to determine the age of the object.

Carbon14 is also passed onto the animals that eat those plants after death the amount of carbon14 in the organic specimen decreases very regularly as the molecules decay carbon14 has a halflife of 5730 177 40 years meaning that every 5700 years or so the object loses half its carbon14.
