Pangea

At the start of the Mesozoic Era, all the land areas on earth were connected in a gigantic supercontinent which is called Pangea. The supercontinent eventually broke up and drifted apart.

Pangea was about twohundred million years ago. Pangea was broken into two huge land masses called Laurasia and Gondwanaland, and present continents forming today. According to theiry, all continents once were formed a part of a gigantic single land mass named Pangea. Although most of the earth's crust is in the Northern Hemisphere, half of Pangea was in the Southern Hemisphere. What is now the U.S. was near the equator, perhaps for cast of it's present position. india - which at the time was not a part of Asia - lay near the South Pole.
