  • Documents intervals of geologic time relative to one another

  • Continuously developed and updated

  • Relative dating of periods in Earth's history

  • Divided on the basis of the earth's biotic composition

  • Phanerozoic Eon (i.e. the Paleozoic, Mesozoic and Cenozoic Eras): Earth's with advanced life forms

    • Fossils appeared in an orderly fashion in stratigraphic units.

    • Majority of fossil organisms did not match modern groups

    • Three major eras:

      • Paleozoic (meaning ancient life)

      • Mesozoic (meaning middle life)

      • Cenozoic (meaning recent life)

  • Pre Cambrian (or Proterozoic and Hadean Eras): Before advanced life.

  • The modern Geologic Time Scale as shown above is a compendium of both relative and absolute age dating and represents the most up-to-date assessment of Earth's history.
