WALKING WITH BEASTS

Since the dinosaurs died out over 65 million years ago our planet has been dominated by mammals. A succession of bizarre evolutionary specimans have come and gone - from walking whales to sabre-toothed cats. These animals have been recreated by the BBC. Includes the mammoth, giant carnivorous birds, tonne indricotheres, the Apidium, chalicotheres, the Macrauchenia, and the Doedicurus.
