The Theory of Pangaea
By: Haley Kable
Identical plant and animal fossils of the same age have been sound in rocks In Africa and South America. This strongly suggests that the two were once joined. For instance the fern Glossopteros can be dated at 270 million years ago and can be found in banded areas of South America, Africa, India and Australia.
The types of rocks found on each continent today show similar strata and ages. Mountain ranges on the coast of West Africa disappear then suddenly reappear again on the coast of South America. The diagram below shows evidence.
