"Because the time span of Earth's past is so great, geologists use the geologic time scale to show Earth's history. The geologic time scale is a record of the life forms and geologic events in Earth's history. Scientists first developed the geologic time scale by studying rock layers and index fossils worldwide." http://www.ridleysd.k12.pa.us/cms/lib2/PA01001042/Centricity/Domain/629/Geo_Time_Scale_WS.PDF
