Pannotia

When Pannotia subsequently split, about 550 million years ago, the interior oceans created by this event, such as lapetus, Tuzo Wilson's so-called 'proto-Atlantic' separating present-day North America from Western Europe, were subsequently destroyed as the next supercontinent (Pangaea) was created.

The supercontinent status of Pangaea and Rodinia is undisputed. In contrast, there is ongoing controversy on whether Pannotia existed at all.
