Actually I didn't go to your links but I believe that Antarctica shared the same fate that the arctic did. A shifting of our poles led to the north and south pole freezing, hence the Mammoths found frozen with unchewed food still in their mouths etc. Many unexplained things in this world, and many idiotic global warming freaks out there also.
How would a shifting of poles lower the temperature quickly enough to freeze food in the mammoth’s mouths?
