Continental drift after 250 million years, showing the supercontinent of Pangea Ultima, which was named for the ancient supercontinent of Pangea. Pangea began to break up some 200 million years before the modern era, and around 450 million years before the formation of Pangea Ultima. Some of the shapes of today's continents are still visible. Several such supercontinents have formed in the 4.5-billion-year history of the Earth. This map shows extra land that was present when sea levels were low. For the complete set of illustrations of Pangea and Pangea Ultima, from 200 million years ago to 250 million years in the future, with and without labels, and with versions with extra land, see images C046/9220 to C046/9249. For this map with labels, see image C046/9249.
