Explanation:

Alfred Wegner came up with the theory of the continental drift and of the super-continent Pangaea. He proposed that the continents were once a single continent. Fossils of the mesosaurs, for example, could be found only in South America and Africa in their lifetime, but their fossils could be found all over the world.  However, his claims were not excepted until after his death when Harry Hess proved his theory correct with the disccovery of seafloor spreading.
