Pangaea: The Supercontinent That Gave Rise to All Continents

The single landmass from which all modern continents are believed to have originated is Pangaea (also spelled Pangea). It existed during the late Paleozoic and early Mesozoic eras (~335–175 million years ago) before breaking apart through plate tectonics into Laurasia (north) and Gondwana (south), which further fragmented into today's continents.
