Template:Martian range/doc

Usage

 * Note The first parameter (bold above) may not be omitted; in particular it is an error to specify only earliest and/or latest. Italic parameters are optional, bold required.

Illustrates the range of a Martian period of time or a Martian event, the geological range of a stratigraphic unit, or other ranges on a geological timescale. Intended for use in infoboxes. For the full earth counterpart of this template, see Long fossil range. For Proterozoic ages, see Proterozoic time scale. For Phanerozoic ages, see Geological range.

You can give a numeric range, or specify the periods involved (Martian periods currently do not work at the moment, This will be fixed in the future). The range will be quoted in text before the timeline, unless you specify a third parameter—leaving it blank will result in no text being provided.

To illustrate the range when dealing with stretches of time or events on Earth, you should use Template:Long fossil range, which works in exactly the same way as documented here.

You can also specify "earliest" and "latest" to add a "ghost" bar beyond the accepted fossil range. You can use these parameters for whatever you like; they may be useful in the case of disputed upper and lower boundaries for given periods of time.

Examples
If you receive an error when specifying a period name, check you've spelt it right; if so, it probably isn't yet incorporated into the templates next period and period start. This is really easy to do, so feel free to add the period yourself to make future editors' lives easier!
