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>
This clickable timeline template, wikilinked to over 30 Wikipedia articles, translated into over 30 languages, edited by over 110 editors, transcluded to over 100 articles, was originally derived from {{Life timeline}} for inclusion in the article "Timeline of the evolutionary history of life".
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.
The geologic time scale, proportionally represented as a log-spiral with some major events in Earth's history. A megaannus (Ma) represents one million (10 6) years. The geologic time scale or geological time scale (GTS) is a representation of time based on the rock record of Earth.

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 ...
To change this template's initial visibility, the |state= parameter may be used: {{Geological history of Earth | state = collapsed}} will show the template collapsed, i.e. hidden apart from its title bar. {{Geological history of Earth | state = expanded}} will show the template expanded, i.e. fully visible.
