The geological time scale divides the history of the Earth into units of time based on layers of rock (strata). It is the foundation of earth science. Paleontologists use it to date when various species lived. This chart is essential to the study of both earth and life science.
This poster presents each period of geological time through a strip of illustrations. Each period is introduced by informative text, followed by illustrations showing life both on land and in the seas, index fossils and a globe showing the position of the continents.
