No internet connection required. Ideal for field use.
TWO DIFFERENT VIEWS FEATURED:
The Geologic Time Scale Without Ages shows the names of eons, eras, periods, and epochs and their corresponding dates. Touching the With Ages button adds the names of the ages within the epochs along with their corresponding dates. Information icons appear at several points on the scale. Touching each of these icons reveals additional information about which phenomenon occurred at that time such as the extinction of the dinosaurs at 65.5 Ma.
