The following five timelines show the geologic time scale to scale. The first shows the entire time from the formation of the Earth to the present, but this gives little space for the most recent eon. The second timeline shows an expanded view of the most recent eon.
|labels= optional - Sets geological time labels to be displayed (era, period, epoch, age) Period options: cenozoic not functional - displays entire Cenozoic timescale; quaternary not functional - displays Quaternary timescale; neogene not functional - displays Neogene timescale; paleogene not functional - displays Paleogene timescale
If the template has a separate documentation page (usually called "Template:template name/doc"), add [[Category:Geological range graphical timeline templates]] to the <includeonly> section at the bottom of that page. Otherwise, add <noinclude>[[Category:Geological range graphical timeline templates]]</noinclude>
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).
Illustrates the fossil range of a taxon, the geological range of a stratigraphic unit, or other ranges on a geological timescale. Intended for use in {{taxobox}}es, {{Infobox rockunit}} s, and other infoboxes. For pre-Phanerozoic ages, see {{Long fossil range}}. You can give a numeric range, or specify the periods involved.

Geologic time is the timescale used to calculate dates in the planet's geologic history from its origin (currently estimated to have been some 4,600 million years ago) to the present day. Radiometric dating measures the steady decay of radioactive elements in an object to determine its age. It is used to calculate dates for the older part of ...
Before I made this template sortable the start of the Eoarchean is exactly 4 billion years ago. Start dates for eras in the Hadean is taken from Geological history template. So Cryptic starts 4567mya, Basin Groups 4.5bya, Nectarian 4.3bya, and Early Imbrian 4.1bya. Now to make this template become sortable efficiently The rowspan and major ...
