Collateral Damage

About 250 million years ago, the two supercontinents, Gondwana and Laurasia, started breaking up. Gondwana and Laurasia contained virtually all the world’s land mass; Gondwana in the South was made up of what is now Australasia, India, Africa, Antarctica and South America, and Laurasia in the North was made up of Eurasia and North America. It is thought that the splitting up of these continents gave rise to a great deal of volcanic activity. Another theory is that a meteorite may have hit the earth at this time, but if it had done any evidence has been buried by over 200 million years of continental drift.
