 Geological timescale template

 Usage

Use the format {{Ma|Years_ago|Suffix|error=Error}}

Years_ago can take a number (don't include commas, which are added automatically), or a period name (e.g. Cambrian), in which case it will return the date the period started.

Suffix is optional and defaults to "million years ago".

Error is an uncertainty and will be displayed as ± error. If a non-numeric value is entered, it will show the error associated with the period specified in Years_ago.

 Examples

• {{mya|65|million years old}}

gives

65 million years old

(and the "million years old" will not wrap; it will remain on the same line.)

• {{mya|Cambrian|MA|error=show}}

gives

CAMBRIAN± 0.3 MA

• {{Ma|250|error=5}}

gives

250 ± 5 مليون سنة مضت

• To cite a range of years, {{Ma|250|65}}

gives

250 to 65 مليون سنة مضت

 Rationale

With geological time, it is often genuinely useful for the lay reader, with little grasp of how long ago 500 million years really is, to be able to quickly flick to a timescale.

Hence, this template allows an easy way to implement such links.
