Walking with Dinosaurs Episode 5 - Spirits of the Ice Forest Episode Title:Spirits of the Ice Forest.Episode Description:A few hundred kilometres from the South Pole, a clan of herbivorous Leaellynasaura are seen emerging to activity after months of total darkness. Now with the coming of spring, the members of the clan are shown feeding on the fresh plant growth and building nests so they can lay their eggs. A male amphibian Koolasuchus has also woken up from hibernation and heads to a river where he will stay during the summer. Out on the rocky river banks, migrating herds of herbivorous Muttaburrasaurus have arrived to feed on the fresh vegetation and lay their eggs, also dealing with blood-sucking insects. By summer, many of the Leaellynasaura clan's eggs have been eaten, but those of the matriarch hatch successfully. A male polar allosaur is shown hunting the Leaellynasaura and Muttaburrasaurus.
