David A. D. Evans and Ross N. Mitchell combined paleomagnetism with the record of ancient continental margins to reconstruct a core of the supercontinent Nuna. Rotating same-age paleomagnetic poles into a common reconstruction tests whether the proposed continental neighbors share a compatible history. The study compared Siberia, Laurentia and Baltica, using agreement and later divergence of their records to constrain assembly and separation. These magnetic tests complement geological fits rather than assuming that a visually plausible arrangement uniquely reconstructs a vanished supercontinent.[ref]
