The Devonian graphical timeline is used to display a timeline of the main events and subdivisions that have occured during the Devonian Period.
Usage
[edit]
{{devonian graphical template |title_colour= |chrono_unit= |embedded= }}
|
Parameters
[edit]The following parameters can be used for this template:
- title_colour: The color of this timeline's title. This value must be a valid subdivision of the geological time scale, as each subdivision is connected to a certain color.
- embedded: Determines if the outside border and title of this timeline will not be visible. This property is enabled if this parameter is set to a value equivalent to
true. - chrono_unit: Determines which type of subdivision will show up that the beginning and end of the timeline. This parameter only accepts two values:
epochandage.
