A supercontinent made up of all the world's present landmasses joined together in the configuration they are thought to have had during the Permian and Triassic Periods. According to the theory of plate tectonics, Pangaea later broke up into Laurasia and Gondwanaland, which eventually broke up into the continents we know today.
