Originally fossils only provided us with relative ages because, although early paleontologists understood biological succession, they did not know the absolute ages of the different organisms. In geology, an absolute age is a quantitative measurement of how old something is, or how long ago it occurred, usually expressed in terms of years. Cart 0.

We have already discussed determining the relative ages of events. As we learned in the previous lesson, index fossils and superposition are effective methods of determining the relative age of objects. September 30, by Beth Geiger. The most widely known form of radiometric dating is carbon dating. Geochronology is the science of providing ages of events in the history of the Earth and extraterrestrial material and of determining the temporal rates of geological processes by using a number of different dating methods.
