Alfred Wegener believed that that the puzzle like fit wasn't just a coincidence. He believed that the continents were once connected at one landmass. He called this landmass Pangaea, which means "all land." Wegener believed that Pangaea broke apart 250,000,000 years ago. In 1912 Wegener proposed the idea of continental drift. Continental drift states that the continents have moved horizontally to their current location. Although this concept was not accepted before Wegener died in 1930 it is now believed to be very true. There is now a lot of evidence that makes Pangaea and the theory of continental drift believable.

One of the pieces of evidence that was found was fossil clues. In South America and Africa fossils of the reptile Mesosaurus were found. How could...
