South America and Antarctica

This is two years old, but utterly fascinating:

Think of it! Antarctica, lush and green, with forests and all sorts of different life. And while moving to a more southern latitude certainly had a role, it is now believed the ocean currents are what froze the continent.

But wait - almost more interesting: the Pacific and Atlantic oceans were not joined in the south before this. I do not know when Laurasia split and the Arctic Ocean was formed...but only 41 million years ago? Even if that is twice as long as was once thought, its still not that long. Pangaea was 250 million years ago.

That is old.
