Pangea, believed to be a super continent, was formed by all the continents. Scientist believe that the east of South America fit into the west of Africa just like a jigsaw puzzle. Sea floor spreading caused Pangea to break apart. The continents then drifted away. Fossils of the same kind were found on different continents. In the early 1900's, Alfred Wegener proposed the idea of Continental Drift. He thought, this idea was the thought of continents moving. Pangea was thought to be formed by the fragments of another supercontinect, Rhodinia. After Rhodinia drifted apart, the continents eventually started drifting together again during the Paleozoic period.
