Alfred Wegener - From Continental Drift to Plate Tectonics
... "Doesn't the east coast of South America fit exactly against the west coast ofAfrica, as if they had once been joined? Don't the coal deposits found in A ntarctica lead to the conclusion that it must have been near to the equator for the rich vegetation to thrive?" argued Wegener. He also noted that ...
