Usage guideline
By consensus at Wikipedia:WikiProject Geology, this template should only be used on the articles about geological time periods that it links to. It should not be used in categories, nor for extinct taxa, nor geological formations.
This template's initial visibility currently defaults to autocollapse, meaning that if there is another collapsible item on the page (a navbox, sidebar, or table with the collapsible attribute), it is hidden apart from its title bar; if not, it is fully visible.
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.
