You may have noticed that some of the boundary ages are different between the timescales in Figure 3-3. This is because the timeline is constantly being refined with the discovery of new rocks and use of improved dating techniques. On the Geologic Time Scale, the Cenozoic Era covers from approximately 66 million years ago to the present. On the Geological Time Scale, this period of time corresponds with the extinction of the dinosaurs and the rise of mammals.
