Scientists often use fossils to evaluate the theory of [[evolution]]. They record the species that they find and compare them to living species in order to create a [[fossil record]] of life of Earth.[http://pubs.usgs.gov/gip/geotime/radiometric.html] [http://www.fossilmuseum.net/]

Scientists use a process known as [[radiometric dating]] to determine the age of the fossils. Radiometric dating is a technique in which scientists observe the ammount of an elemental [isotope] within the fossil, then use the known decay rates of isotopes to calculate when the organism died. There are a number of different methods, some of which can be used to date a specimen that died up to three billion years ago. [http://www.gpc.edu/~pgore/geology/geo102/radio.htm]
