Researchers from Norway, South Africa, Britain and Germany, in the last week of February 2013 discovered a sunken and small continent beneath the Indian Ocean. This is the ancient and mini continent named Mauritia and it lies beneath the lava flows which led to the formation of islands of Mauritius and Reunion.
This lost continent called Mauritia, dates back to the time when the super continents of the Earth- Laurasia and Gondwana shattered into the familiar geography like present. Mauritia is said to be a part of the mass of Gondwana which had eventually split into Antarctica, India, Australia and Madagascar after around 170 million years ago.
The mini continent was later torn apart as it passed over the mid-ocean ridges. The lava eruptions later covered this sunken continent. But later, due to the volcanic eruptions on the Island of Mauritius the pieces of this lost continent were brought on the surface of the Earth. These pieces were crystals called zircons which dated back to 660 and 1970 million years ago. This hinted towards the fact that the rock which lied beneath the crust was in fact the part of this ancient mini-continent.
The team of geoscientists also suggested that there might be other lost micro-continents on Earth which are buried beneath the lava.
