Prehistoric Earth 550 million years ago. Artwork of prehistoric Earth seen from space 550 million years continent, known as Gondwana, is thought to have existed (left half of globe) as well as the continents of Laurentia (upper right), Baltica (lower right) and Siberia (unseen). Continents come together or break apart over the surface of the Earth as a result of movements in the fluid mantle below the crust. The landmasses here are thought to have collided with each other to form the supercontinent Pangaea 225 million years ago, which itself broke up to eventually form the continents of the present day.
