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 {{taxobox}}es, {{Infobox rockunit}}s, and other infoboxes. For pre-Phanerozoic ages, see {{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 "cynharaf" and "diweddaraf" 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 diweddaraf=0 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 cynharaf=Cambriaidd Canol.

Examples

Cretasaidd Diweddar
{{Amrediad daearegol|68|65|}}

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 {{Cyfnod nesaf}} and {{Dechrau cyfnod}}. This is really easy to do, so feel free to add the period yourself to make future editors' lives easier!
