Aurica is roughly similar to Novopangaea, but posits a rift separating China and India from the rest of Eurasia, causing the former to collide with Australia from the west while the latter circles the globe eastward before docking with the new supercontinent.However the next supercontinent arises, the cycle will have cataclysmic environmental effects.
