Extinct creatures

This is a list of creatures that are extinct. This list includes Maxis-created creatures extincted by technical restrictions, or creatures that appeared before the game was launched but didn't appear in the final version.

This list can also includes user-created content that the creator considers to be extinct within their fiction. It should not include creatures from groups that are extinct as a whole unless it's been specified on the page, and user-made creatures should not be added to this category without the consent of the creator.
