The water deposits that were being made required thousands of centuries for their completion.

At the beginning of the Quaternary period there were alive the cave-bear, the cave-lion, the amphibious hippopotamus, the rhinoceros with chambered nostrils, the mammoth.

In fact, the mammoth swarmed.

He delighted in a boreal climate.

By degrees the reindeer, the horse, the ox, the bison, multiplied, and disputed with him his food.
Partly for this reason, and partly because of the increasing heat, he became extinct.
