==Usage==
 <code><nowiki>{{</nowiki>Geological range|'''first appearance''' (required)|''last appearance''|''text to display''|earliest=''earliest putative fossil''|latest=''latest putative fossil''|ref=''References''|prefix=''anything to display before the range''|PS=''anything to display after the range''}}</code>

: '''Note''' The first parameter (bold above) may not be omitted; in particular it is an error to specify only {{para|earliest}} and/or {{para|latest}}. Italic parameters are optional, bold required.
{{Automatic taxobox
 |fossil_range = {{Geological range|Carboniferous | early Cretaceous|earliest=Ordovician}}
| taxon = Rangea
}}
Illustrates the fossil range of a taxon, the geological range of a stratigraphic unit, or other ranges on a geological timescale. Intended for use in {{tn|taxobox}}es, {{tl|Infobox rockunit}}s, and other infoboxes. For pre-Phanerozoic ages, see {{tl|Long fossil range}}.

You can give a numeric range, or specify the periods involved. 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 it spans before the [[Ediacaran]] (i.e. deep into the Precambrian), 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 living fossils such as the [[coelacanth]], where you may wish to specify <code>latest=0</code> to make the bar faintly extend to the present; they may also be useful where "earliest" fossils are not universally accepted—for instance, the [[octocorals]] only have a good fossil record from the Ordovician, but there are claims of Cambrian representatives. In this case, you may wish to specify <code>earliest=late Cambrian</code>.

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 {{tl|next period}} and {{tl|period start}}. The pages are [[Wikipedia:Template protection|template protected]] due to their high use, but feel free to add an edit request on their talk pages to make future editors' lives easier!

For organisms whose fossil range extends significantly before the Ediacaran, use [[Template:Long fossil range]].
