Continental Jigsaw
From GeoClasses
Observe the shape of South America and Africa.
Looking at the shape of the continents (particularly in if you consider the continental shelves) the continents align very nicely.
- Note Africa and South America
- Note Africa and North America
This idea is not new.
In 1858, geographer Antonio Snider-Pellegrini made these two maps showing his version of how the American and African continents may once have fit together, then later separated. Left: The formerly joined continents before (avant) their separation. Right: The continents after (aprés) the separation.

The theory that the continents move is called Continental Drift
