'The colorful previous editions of the Geological Time Table have been immensely popular with scientists, professors, and students alike. The new and revised sixth edition provides practicing geologists, archaeologists, and Earth historians with a succinct source of reference to stratigraphy and chronostratigraphy. It provides easy access to numerical ages, including the stratigraphic subdivisions and the ages of prominent mountain-building, paleoceanographic, paleoclimatological and evolutionary events in Earth history. The linear time scale has been thoroughly revised, utilizing recent developments in geochronology and radiochronology, especially where there have been major revisions in age dating. An attempt has been made to update all regional stratigraphic schemes based on the most recent information. It also lists major events in how mountain ranges are formed, geomagnetic polarity reversal, and unusual seafloor magnetic records, where available. Major biotic events, prominent geodynamic, oceanographic and geochemical events and glacial episodes of the Phanerozoic can also be found for quick reference. A series of paleogeographic maps showing major geographic and oceanographic changes are included as an educational tool and glacial and archaeological classifications complete the utility of the chart for paleoclimatology and archaeology. An index is provided for quick and easy reference to the terms within the body of the Table.'
