C-14 and u-238 used for fossil dating the age is calculated from the position of the fossil or rock relative to the position of nearby igneous rocks. Uranium 238 is only found in igneous or volcanic rocks so no fossils can be dated directly using u 238 dating used together in order to determine fossil ages. An essay on radiometric dating u238 and u235 are both nuclides of the is even better than potassium-argon dating for old rocks the nuclide.
