Let's just hope they don't also discover a couple of hundred thousand IT grads looking for work..

Yeah, we have enough unemployed already

A supercontinent, the sole big landmass on the planet, has formed every several hundred million years or so, during continental drift, and several have now been inferred and named, including likely future ones.

Yes, Im aware there have been other 'super continents.' My point was that scientists seem to contend that these super continents all contain the current continents and not, some unknown landmasses that have now been subducted.

Given the planet has tectonic plate activity, I find it odd that scientists insist pangea was the only landmass before it split apart.

Atlantis?

In the Indian Ocean? That would be a quirk of fate.

The forming of supercontinents and their breaking up appears to have been cyclical through Earth's history. There may have been several others before Pangaea. The fourth-last supercontinent, called Columbia or Nuna, appears to have assembled in the period 2.0–1.8 Ga.[5][6] Columbia/Nuna broke up and the next supercontinent, Rodinia, formed from the accretion and assembly of its fragments. Rodinia lasted from about 1.1 billion years ago (Ga) until about 750 million years ago, but its exact configuration and geodynamic history are not nearly as well understood as those of the later supercontinents, Pannotia and Pangaea.

Seems the wiki authors are happy with more than one supercontinent. I keep reading that as Rodney.

BBC News - Fragments of ancient continent buried under Indian Ocean

All interesting but I was struck by this phraseThat's a little open-ended... are they trying to keep the creationists happy?

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