Fossils and rock age

Added by Lawrie Ryan on Mar 19, 2008

A graphic showing how fossils can be used to help determine the age of rocks. The oldest fossils must have been deposited first. If the same fossil species are found in rocks from different parts of the world, we may deduce that the rocks are of a similar age.

This resource is from the unit The Rock Record which is part of Absorb Chemistry.
