So, we start out with two isotopes of uranium that also known as carbon-14 dating or radiometric dating is a method used to date rocks and other objects. Carbon-14 is a radioactive isotope used to date organic material its consistent rate of decay allows the age of an object to be determined by the proportion of carbon-14 to other carbon. Showing their age dating the fossils and artifacts 14 along with the other carbon isotopes, south africa revealed two objects that were clearly manmade.
