The original supercontinent first envisaged by Wegener is referred to as Pangea.
Wegener, a believer in the continental drift theory, postulated that all Earth's continents were once part of an enormous, single landmass called Pangea. Pangea was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. The landmass was surrounded by a global ocean called Panthalassa.
According to the continental drift theory, the supercontinent Pangea began drifting or breaking apart about 200 million years ago. This period traces back to the early Jurassic Epoch. Eventually, the Pangea drifted away and resulted in the formation of the modern continents and the Atlantic and Indian oceans.
