Walking with Prehistoric Beasts

The late Eocene is a time of great change, but not a pleasant one for Earth's life form. Antarctica has separated from the other continents and is slowly freezing, changing the ocean currents. This is playing havoc with the climate, creating environmental disasters worldwide. Into this world has evolved the most fearsome whale ever to live; Basilosaurus. With ocean food stocks in chaos, a female Basilosaurus must search her home in the Tethys Sea from north to south, to satisfy her enormous hunger. And she is also pregnant...

The Pliocene has arrived, and the world is taking on its familiar shape. In the Great Rift Valley of Africa, the animals are taking familiar forms, though some exotic forms are wondering around with animals modern man would be familiar with. It is here that a new species of ape has evolved, one that will one day evolve into the most powerful animal ever seen.

The Ice Age has arrived, putting life in the freezer. It is at this time when great herds of Woolly Mammoths live on the plains of what will eventually be the North Sea. As winter arrives, the Mammoth herds head south, moving to greener pastures. It is not an easy journey, especially for the young. Predators are everywhere, and the most dangerous of all are two species of humans that share the Ice Age environments of the mammoths.
