The Geological periods task force is a group of editors aiming to improve Wikipedia's articles about the geological periods, as part of WikiProject Geology, WikiProject Dinosaurs and WikiProject Palaeontology.

With articles on the periods receiving around a thousand hits a day, they are some of the most visited geology articles, but many are in need of attention and expansion!


To bring each of Wikipedia's articles on geological periods to a common standard, comprehensively covering all major aspects of the period.

Each article should begin to address the contemporary geography, geology, climate, and geochemistry, as well as detailing life at the time - the marine (including reefs) and terrestrial fauna and flora. It should also provide an outline of any significant events (for example the PETM or Cambrian explosion) and document any historical significance attached to the period.

Collaboration of the month[edit]

This month's period for improvement is the Jurassic. Please help expand this article in any way you can!


Please find any cell that interests you and try to bring it up a grade! We're aiming for a "A" in every box...

You can help by assessing articles in each of the areas listed above. The grading scale is as follows:

A-Class article A Well written, comprehensive and fully sourced report of all aspects of the subject. May form a separate article (e.g. "Devonian fauna"), which the main article summarises.
B Reasonably comprehensive but room for improvement.
C Makes a good stab at addressing the issue; all the major components are at least noted, but significant expansion is necessary.
Start A good start: at least a paragraph addressing the topic.
Stub Topic is mentioned somewhere in the article.

We're also looking to create a uniform look and feel to all articles about geological time periods. To this end we're working on the infobox-style templates listed below. If you can think of any way to improve this boxes, please speak up!


Everybody is encouraged to help out with the tasks listed above, as they wish! You may also wish to add this page to your watchlist to keep an eye on developments.

Project banner[edit]

Place {{WikiProject Geology|class=|importance=|Geological periods=|Geological periods-importance=}} onto any new article's talk page for it to be recognised and assessed under the scope of this task force. An article's assessment is generated from the class and importance parameters and helps organise relevant articles for improvement. When assessed, the class and importance parameters are filled in, like this:

{{WikiProject Geology|class=Start|importance=Mid|Geological periods=yes|Geological periods-importance=High}}

and the banner looks like this:
