Modified from the following: GSA Geologic Time Scale v. 5.0 and International Chronostratigraphic Chart v. 2018/08 References: Geologic time periods are what geologists and paleontologists use to organize the time flow of earths history. Because of the huge scope of time, 4.5 billion years, it is helpful to break it up into smaller chunks. The known geological history of Earth since the Precambrian Time is subdivided into three eras, each of which includes a number of periods. They, in turn, are subdivided into epochs and stage ages. In an epoch, a certain section may be especially well known because of rich fossil finds. Geologic time scale Take a journey back through the history of the Earth — jump to a specific time period using the time scale below and examine ancient life, climates, and geography. You might wish to start in the Cenozoic Era (65.5 million years ago to the present) and work back through time, or start with Hadean time (4.6 to 4 billion years ago)* and journey forward to the present day — it's your choice. The principal chart shows the Phanerozoic (Cambrian to Quaternary) timescale. The names of the individual periods are links: each one leads to a more detailed chart showing the epochs and ages for that period. The charts for the individual periods are all drawn The Geologic temperature record are changes in Earth 's environment as determined from geologic evidence on multi-million to billion (10 9) year time scales. The study of past temperatures provides an important paleoenvironmental insight because it is a component of the climate and oceanography of the time.

Convert each geologic time period from millions of years ago (mya) into yards on a football field, 19 Jul 2018 "The Meghalayan Age is unique among the many intervals of the Geologic Time Scale in that its beginning coincides with a global cultural chart and the youngest is at the top. Both absolute and relative ages of rocks and fossils supplement interpretations from rocks. The vastness of geologic time All of these temporal subdivisions are established on the occurrence of some important geologic event. For example, Hadean Eon represents the time on Earth
Purchase Geologic Time Scale 2020 - 2nd Edition. the creation of an international geologic time scale, and the included charts present the most up-to- date, The geological time scale--shown above in a simplified form--is one of the crowning achievements of science in general and geology in particular.
