Walking With Beasts - Ep 1 New Dawn (2001) [576p]

For 160 million years dinosaurs have ruled the world, while mammals have lived in their shadow. Then a meteor crashes into the Earth wiping out the dinosaurs. 15 million years on, the world has changed. The sea level has risen and the temperature has reached an all time high. No animal has risen to take the place of the dinosaurs. Birds, reptiles, mammals and insects live together waiting to establish a new order. The film is about a Leptictidium, a highly successful mammal typical of this time.
