Radioisotope Dating Methods that date the rock, not the fossil itself.
Radioactive dating is a method of dating rocks and minerals using radioactive isotopes. This method is useful for igneous and metamorphic rocks, which cannot be dated by the stratigraphic correlation method used for sedimentary rocks. Over naturally-occurring isotopes are known. Some do not change with time and form stable isotopes i.

How Old Is the Earth: Radioisotope Dating
Scientists estimate that the Earth is about 4. To understand how this process works, you need to know a little bit about atoms and isotopes. Often, any one atom has several different forms, called isotopes. Atoms are made up of electrons, protons, and neutrons, and the number of electrons and protons determines the type of atom. Hydrogen, for example, has one electron and one proton.
You've got two decay products, lead and helium, and they're giving two different ages for the zircon. For this reason, ICR research has long focused on the science behind these dating techniques. These observations give us confidence that radiometric dating is not trustworthy.
