Alfred Wegener had a theory. That theory was that all of the continents were once joined together to make one giant land mass. It was called Pangaea. He also had five proofs: Jigsaw Puzzle Fit: Matching coastlines. The continents seem to fit like puzzle pieces. (South America fits right into Africa) Plants and Animals Match: Fossils of late Paleozoic age were found on several different continents. South America and Africa have matching fossils. Rock Match: South America and Africa have the same kinds of rocks. They also have the same mountains chains. Its like there cut in half. Ice Matches: An ice sheet covered parts of India, Africa and South America. Positions Don't Match: 300 million years ago the present northern continents were at the equator. Tropical plants were found in Antartica.
