The supercontinent that included all of Earth's land surface about 200-300 million years ago. When Alfred Wegener proposed his theory of continental drift, he suggested that today's continents had originally been a single landmass, before moving to their present positions. Several lines of evidence, including fossils, geological and geomagnetic data, all now suggest that he was right.
