Well, we all know that they ate grasses that shouldn't have existed in Siberia (unless it was prior to a poleshift).

Now scientists are saying:

"Woolly mammoths, horses and bison that lived during the last Ice Age more than 24,000 years ago managed to survive by dining on a menu of grasses and prairie sage"

[ Well, der, it's what was in their stomachs! ]

"They think Beringia was covered with the vegetation even during the coldest part of the Ice Age which is how the ancient creatures survived. "

[ With no explanation given as to how the grass grew. Pole shift believers know the answer! ]
