Across the Pond
Look closer. The right side of South America once snuggled into the left side of Africa. For hundreds of years, since the development of good global maps, we suspected it but didn't know it.
A century ago, geologists too were in a process of upheaval. In 1915, Alfred Weneger outlined this theory in The Origins of Continents and Oceans. But Weneger had more than a map: he had fossils.
Mesosaurus was too little of a croc to swim across oceans, but lived on both sides.
And Glossopteris was a seed fern whose seeds were too fat to blow so far.
