== Original instructions copied from en:wiki ==
Illustrates the fossil range of a taxon. Intended for use in {{tn|taxobox}}es.
Line 22 ⟶ 24:
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 [[coelocanth]], 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 Tertiary, but there are claims of Cambrian representatives. In this case, you may wish to specify <code>earliest=middle Cambrian</code>.

The best way to use this formula is to specify a date range in millions of years and also the first and last geological periods/epochs. If this is done, all the information will appear clearly both in text form and in the timeline diagram. The Latin or English formula name will work:
===Examples:===▼
Then add the date range. For a living taxon, the second number will be 0:
<pre>{{Scala fossilis|299|201</pre>
<pre>{{Scala fossilis|20|0</pre>
The formula can be closed here. If it is, the screen rendering will show the date range on the timeline and in text form:
<pre>{{Scala fossilis|299|201}}</pre>
But it is better also to add the geological periods (the first and last, or the only one). The parameter including this information must be labelled "|r=". Our equivalent of the conventional term "recent" is "[[Recens]]", which is currently redirected to [[Holocaenum]]. Thus:
<pre>{{Scala fossilis|299|201|r=[[Permium]] > [[Triassicum]]}}</pre>
<pre>{{Scala fossilis|20|0|r=[[Miocaenum]] > [[Recens]]}}</pre>
What follows the r= is treated as text, and it can include a footnote. Here are examples of the formula as rendered:
<pre>{{Scala fossilis|299|201|r=[[Permium]] > [[Triassicum]]}}</pre>
