It's used to date the carbon and fossil fuels that emerge from a very old fossil. I think this is correct, not completely sure. Hope it helps anyway!
Thus, measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of fossils and a planet of 4.6 billion years.
What are fossils?
Fossils are the preserved remains, or traces of remains, of ancient organisms.
Age of fossils is known by the method of carbon dating and by measuring the height, the more deeper u will find a fossil, the more it's ages.
Another common method, uranium-lead dating, relies on the radioactive decay of uranium and can be used to date rocks containing the oldest known fossils on Earth—older than 3.5 billion years old!
As the uranium in rocks decays, it emits subatomic particles and turns into lead at a constant rate.
Thus, measuring the uranium-to-lead ratios in the oldest rocks on Earth gave scientists an estimated age of the planet of 4.6 billion years.
