The geologic time scale or geological time scale ( GTS) is a representation of time based on the rock record of Earth. It is a system of chronological dating that uses chronostratigraphy (the process of relating strata to time) and geochronology (a scientific branch of geology that aims to determine the age of rocks).The primary objective of the International Commission on Stratigraphy (ICS) is to precisely define global units (systems, series, and stages) of the International Chronostratigraphic Chart that, in turn, are the basis for the units (periods, epochs, and age) of the International Geologic Time Scalegeologic time scale v. 6.0 cenozoic mesozoic paleozoic precambrian age epoch age picks magnetic period hist. chro n. polarity quater-nary pleistocene* holocene* calabrian gelasian c1 c2 c2a c3 c3a c4 c4a c5 c5a c6 c6a c6b c6c c7 c5b c5c c5d c5e c8 c9 c10 c7a c11 c12 c13 c15 c16 c17 c18 c19 c20 c21 c22 c23 c24 c25 c26 c27 c28 c29 c30 0.012 1.8 3 ...Climate history over the past 500 million years, with the last three major ice ages indicated, Andean-Saharan (450 Ma), Karoo (300 Ma) and Late Cenozoic.A less severe cold period or ice age is shown during the Jurassic-Cretaceous (150 Ma)..

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. Which is why it was called the Cenozoic Era because this name means “new life” in Greek.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. Using a variety of techniques and dating methods, geologists have been able to ascertain the age of the Earth, as well as major eras, periods, and epochs within Earth's history.The largest defined unit of time is the supereon composed of Eons. Eons are divided into Eras, which are in turn divided into Periods, Epochs and Stages. At the same time paleontologists define a system of faunal stages, of varying lengths, based on the kinds of animal fossils found there.
