We need to look carefully at the ground under our feet.

Once upon a time, South America lived harmoniously alongside Africa until a crack in the Earth drove the two continents apart.This breakup began about 200 million years ago during the separation of the supercontinent known as Pangaea.Their proximity back then explains why the same plant fossils and reptile fossils,like the Mesosaurus,can be found on the South American east coast and African west coast.However, this evidence does not account for how the continents moved apart.For that, we'll need to take a close look at the earth below our feet.
