Due to the effects of Continental Drift, how many continents were there before we had seven?

It is surmized that the Earth originally had two "super-continents". Gondwana , originally Gondwanaland, is the name given to a southern precursor-supercontinent. Its final joining occurred between ca. 570 and 510 Ma ago, joining East Gondwana to West Gondwana. It later separated from Laurasia 180-200 million years ago during the breakup of the Pangaea supercontinent that existed about 500 to 200 Ma ago into two large segments, nearly equal in area. At the beginning of the Mesozoic, Gondwana formed the southern part of the single continent Pangaea. When Pangaea split about 200 million years ago, Gondwana began its own isolated journey and gradual break-up into the landmasses we know today – Australia, South America, Africa, India, Madagascar, Antarctica and New Zealand. This palaeo-history is recorded in identical rocks and fossils found across these modern landmasses. When we reconnect them as they were in the past, the rocks and fossils clearly match up. http://australianmuseum.net.au/Gondwana-the-southern-super-continent http://en.wikipedia.org/wiki/Gondwana Oct 02 09, 8:42 PM
