   • 2007, Ted Nield, Supercontinent: Ten Billion Years in the Life of Our Planet, page 207:

     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.

   • 2021, J. B. Murphy, R. A. Strachan, C. Quesada, editors, Pannotia to Pangaea […] , Geological Society of London, →ISBN, page 82:

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