Radiometric dating
Bracketing fossils.
Fossils general found in sedimentary rocks, which can only be dated younger than 50,000 years (because carbon decays relatively quickly) so for older fossils they date igneous rock above and below the target fossil using elements that decay at a slower pace. Eg. Uranium and potassium. This is known as bracketing the age of the sedimentary layer in which the fossils occur.
Stratigraphic dating
Comes from the Latin word stratum, meaning ‘layer’. Using the layers of the earth/rock.
