Fragments of ancient continent buried under Indian Ocean

Fragments of an ancient continent are buried beneath the floor of the Indian Ocean, a study suggests.

Researchers have found evidence for a landmass that would have existed between 2,000 and 85 million years ago.

The strip of land, which scientists have called Mauritia, eventually fragmented and vanished beneath the waves as the modern world started to take shape.

The study is published in the journal Nature Geoscience.

still a big window, but makes more sense that way. They're talking geologic times.

But even that doesn't make much sense if we assume the earth is about 4.5B years old and during that time, a supercontinent has formed and fragmented TWICE, which has been the prevailing theory.
