Geologists have studied the order in which fossils appeared and disappeared through time and rocks. Fossils can help to match rocks of the same age, even when you find those rocks a long way apart.This matching process is called correlation, which has been an important process in constructing geological timescales.Suppose you find a fossil at one place that cannot be dated using absolute methods.That fossil species may have been dated somewhere else, so you can match them and say that your fossil has a similar age.Throughout the history of life, different organisms have appeared, flourished and become extinct.

We will calculate absolute age using radiometric dating principles.Different species of ammonites lived at different times within the Mesozoic, so identifying a fossil species can help narrow down when a rock was formed.Correlation can involve matching an undated rock with a dated one at another location.It teaches them how to evaluate information and how to use the web for something other than You Tube clips of turtles eating tomatoes.Get started with Step 1 below to learn how to make one yourself!
