This gives the fossil an approximate age in years. Absolute dating is often based on the amount of carbon-14 or other radioactive element that remains in a fossil. Relative dating determines which of two fossils is older or younger than the other but not their age in years.

WebAnswer: Radiocarbon dating can be used to find the age of a deceased organism by measuring the amount of Carbon-14 it contains. Carbon-14 is a radioactive element that is present in almost all life forms. Plants turn carbon dioxide into oxygen, thus keeping the carbon inside the plants. A small ... WebRadiocarbon 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, a radioactive isotope of carbon . The method was developed in the late 1940s at the University of Chicago by Willard Libby.
