A lost continent has been found in the Indian Ocean, where it has been sitting underneath the island of Mauritius.
Mauritius has drawn attention because of its particularly strong gravitational pull. Despite only being eight million years old, researchers have found rock samples on its beaches that are three billion years old. The theory goes that the rocks were blown onto the island when volcanoes under the water erupted at some point. (And also that the island itself was formed by a volcano.)
From these findings, the researchers have concluded that there was once a piece of land that connected India and Madagascar, which was another part of an ancient supercontinent called Gondwanaland. Gondwanaland broke apart 200 million years ago, and much of the land sunk in the breaking apart.
