Scientists might have found a lost continent off the coast of Brazil!

A manned Japanese submersible recently shot video of an enormous mass of granite off the coast of Brazil that looks like could be part of a lost continent. If you remember your geology, South America split from Africa millions of years ago. Scientists think that this granite block might have been part of that supercontinent, but sunk when the split happened.

The place is more than 600 miles southeast of Rio de Janeiro and it's 3,000 feet underwater. Brazilian geologists say that granite is not something you find on the seabed because it only forms on land. The next step is to take samples of the granite and see it they match rock from Africa or South America; then we'll know if we're talking about the South American Atlantis.
