ABOUT ANTARCTICA ... (and "ANTEDILUVIAN" cultures, and their possible remnants)
(reposting some years old information from my old facebook/twitter ... there is a lot more to add, i will update when i have more time)
in the Ancient world i believe there was a Civilisation/inhabitants in Antarctica, at a time when it was lush and green ... this was before the previous Geomagnetic reversal. (not 60 million years ago, but tens or hundred+ thousand years ago, possibly a million+ years during a more ancient reversal)
there was a land-bridge that connected South-America to Antarctica, and potentially Australia/New Zealand and South-west Africa. Related information and theories are talked about in an old book: ARCHHELENIS UND ARCHINOTIS:
we can see the remnants of land-bridges most prominently in modern day topography maps and visible maps of the South-America <-> Antarctica region
Japanese Paleolithic & Antediluvian Remnants .
modern findings include fossils of tropical trees which we would expect to find in tropical climates, indicating it was indeed once lush with green vegetation
Regarding the remnants of Antedliuvian culture and peoples; Paleolithic Japan and parts of Australia have evidence of Ground stone & Polished tools with estimated dating around 30,000 BC, considered "neolithic" technology the rest of the world did not develop/discover until 10,000 BC. So far only Japan and some in Australia. This may be a remnant of such Antediluvian people who lived closer to Ancient Antarctica, and had to migrate outwards to South America, South-west Africa, Australia, and towards Japan in the very ancient world.
