To date there have been five mass extinction events on planet Earth. The most widely studied mass extinction event occurred during the Cretaceous period, 66 millions years ago, and took out the dinosaurs and three quarters of all planet and animal life. But the largest mass extinction took place 299 million years ago during the Permian period, when much of the planet’s land mass was still formed into the supercontinent of Pangea. In Pangea, play as the Synapsids, Sauropsida, Amphibians, or Invertebrates (with some very cool, KS-exclusive, animal fossil miniatures) as they prepare for the coming cataclysm by evolving and locating ecological niches as far from the center of the catastrophe as possible.
