Gondwana
On Old Earth, a southern supercontinent prior to the formation of Pangea, and a similar supercontinent formed when Pangea broke to form Gondwana and Laurasia. Gondwana eventuallly broke up to form South America, Africa, Antarctica, and Australia, as well as two portions (India and Arabia) that eventually joined Asia. Distinctive common flora and fauna with ancestry dating back to the middle Jurassic when Gondwana was formed a second time were still identifiable when humanity arose on Old Earth. A number of replicas of Gondwana at various periods have been created by such organizations as the Jurassica Institute.

    On Old Earth, the northern supercontinent formed after Pangea broke up during the Jurassic period. During the Cretaceous period Laurasia had a quite different dinosaurian and mammal fauna to that of Gondwana in the south. Laurasia itself broke up to become North America, Europe, Asia, Greenland, and Iceland.
