What it means
The visual match was noticed centuries ago and dismissed as coincidence, since nobody could suggest a mechanism that would move a continent. The case was rebuilt from matching rock formations, matching fossil species on both coasts, and eventually the magnetic record frozen into the sea floor as it spread. Plate tectonics is now the framework that ties nearly all of geology together.
The claim comes from U.S. National Park Service.
