Absolute dating, also called numerical dating, arranges the historical remains in order of their ages. For example, an especially warm summer might result in a very thick layer of sediment deposited from the melting glacier. As we learned in the previous lesson, index fossils and superposition are effective methods of determining the relative age of objects.

Index fossils contained in this formation can then be matched to fossils in a different location, providing a good age measurement for that new rock formation as well.
