In the last video, we talked about the idea that if i dug up a bone someplace, if i dug up a bone, and if i were to measure its carbon-14, and i found that it had half of the carbon-14 that i would expect to find in a living animal or plant, that i said, hey, maybe one half life has gone by, or roughly for carbon. Discover how archaeologists have been able to use carbon dating to pinpoint the time when sites were in use. Radiocarbon dating (also referred to as carbon dating or carbon-14 dating) is a method for determining the age of an object containing organic material by using the properties of radiocarbon (14 c), a radioactive isotope of carbon. Many fossils are excavated by the archaeologists every year but when it comes to dating archaeological samples, several problems arise to find the period in which that species livedthus in order to find the age of the fossil and the period to which it lived, we use the method of carbon dating.
