Pangaea
prehistoric supercontinent / From Wikipedia, the free encyclopedia
Pangaea[2] was the global supercontinent which formed in the Palaeozoic era. The process started about 450 million years ago (mya) and was complete by 210 mya. So, apart from some volcanic islands (not proven, but very likely), all the land areas were collected together in one big supercontinent.
Pangaea was the latest of a series of global supercontinents. They formed at various times since plate tectonics began on Earth.[3] Panthalassa was the name of the huge global ocean which surrounded Pangaea.
