This template uses Lua:

Module:Geological time (sandbox)

Usage

This infobox template is used to generate an infobox on the right-hand side of articles pertaining to:
a) specific spans of geologic time accepted for general use (i.e Cambrian),
b) regionally used subdivisions of geologic time (i.e Arenig),
c) proposed subdivisions of geologic time (i.e Chaotian),
d) subdivisions of extraterrestrial geologic time (i.e Nectarian).

Parameters

Header and Title Parameters

The following parameters control the images, horizontal timeline bar, and title text at the top of the infobox template.

Header and Title Parameters
Parameter	Function
name	The text at the top of the template.
color	Determines the color behind the title using Template:Period color. A valid period name string is required for this to work. For custom RGB values, see manual_set_color.
manual_color	Sets the color behind the title with RGB values.
top_bar	Determines the variety of horizontal timeline bar below the title text. Defaults to a horizontal Phanerozoic timeline when not invoked. Current accepted values are: - mercury/mercurial (Mercurial geologic timeline) - moon/lunar (Lunar geologic timeline) - mars/martian (Martian geologic timeline) - long fossil/long/all time (complete timeline of earth's history) (NOTE: Upper/lower case does not matter for these values.)
earliest	Adds a translucent green bar to the solid green bar of the horizontal timeline, extending to the earliest possible timeframe the time span could be considered as occupying. It is recommended not to use this parameter unless there is ongoing dispute involving the time span's boundaries. See Template:Geological range for more information.
latest	Adds a translucent green bar to the solid green bar of the horizontal timeline, extending to the latest possible timeframe the time span could be considered as occupying. It is recommended not to use this parameter unless there is ongoing dispute involving the time span's boundaries. See Template:Geological range for more information.
top_bar_ref	Inserts a reference into the text above the timeline bar.
time_start	The time when the geologic time span starts, in millions of years.
time_start_prefix	Used to add a ~ in front of the displayed numerical start time. Should not be used for other purposes.
time_start_uncertainty	The level of uncertainty on the measurement of time span start time.
time_end	The time when the geologic time span ends, in millions of years.
time_end_prefix	Used to add a ~ in front of the displayed numerical end time. Should not be used for other purposes.
time_end_uncertainty	The level of uncertainty on the measurement of time span end time.
top_bar_prefix	Adds text before the "xxx Ma" text above the horizontal timeline. It is recommended not to use this parameter unless absolutely necessary. See Template:Geological range for more information.
top_bar_ps	Adds text after the "xxx Ma" text above the horizontal timeline. It is recommended not to use this parameter unless absolutely necessary. See Template:Geological range for more information.
image_map	Reconstruction of the Earth as it appeared during the geologic time span.
caption_map	Caption for the above image.
image_outcrop	Picture of a rock outcrop with rocks dating to the geologic time span.
caption_outcrop	Caption for the above image.
image_art	Reconstruction of a landscape/ecosystem as it may have appeared during the time span.
caption_art	Caption for the above image.
