Uranium-lead Dating,

Uranium has a half-life of over million years, while uranium has a half-life of about billion years, similar to the age of the Earth itself. These properties mean that the radioactive decay of uranium to lead has previously been used to measure the age of rocks, including those of some of the oldest on Earth, but its use in direct dating of fossils is new.
