Who needs to find Atlantis? It turns out there may be another lost continent currently lying underneath the Indian Ocean. The micro-continent is known as Maurita and began its journey to being lost around 60 million years ago when Madagascar and India began to drift apart. If the theory is correct than the Seychelles are the only part of this continent left above the ocean floor.

How have scientists discovered this? The answer is all in a single grain of sand. Not even a single grain- there were minerals in the sand that dated back at least 600 million years.
