Con radioactive dating can only be used to date fossils older than approximately 50, years old. Pro The half life of radioactive substances are empirically determined. The ratio of the parent to daughter atoms can be used to determine an exact age given the assumptions that none of the original parent atoms have been eroded or lost during the time being calculated. Con All radioactive dating except Carbon 14 are based on atoms found in igneous rocks. Fossils are almost never found in igneous rocks. So radioactive dating can not be used to directly date fossils. The one exception is Carbon

advantages and disadvantages in bold are) o Rubidium - Strontium dating 87 Rb decays to 87 Sr with t 1/2 = x 10 10 years Normalize to non-radioactive 86 Sr When rock forms, ratio of 87 Rb to 86 Sr will vary from place to place in the rock but 87 Sr to 86 Sr ratio is constant. Rubidium-strontium dating, method of estimating the age of rocks, minerals, and meteorites from measurements of the amount of the stable isotope strontium formed by the decay of the unstable isotope rubidium that was present in the rock at the time of its formation. Rubidium comprises percent of the total atomic abundance of rubidium, and of the four isotopes of . Dating - Dating - Rubidium-strontium method: The radioactive decay of rubidium (87Rb) to strontium (87Sr) was the first widely used dating system that utilized the isochron method. Rubidium is a relatively abundant trace element in Earth's crust and can be found in many common rock-forming minerals in which it substitutes for the major element potassium.

So radioactive dating can not be used to directly date fossils. The one exception is Carbon However Carbon 14 has a relatively short half life so it cannot be used on fossils much older than 50, years which makes it useful for anthropology but not geo history.

Also most fossils no longer contain Carbon they have been turned to stone. Radioactive dating gives hope for an objective empirical method of determining the age of fossils.
