Spirits of the Ice Forest is the fifth episode of Walking with Dinosaurs, set in the middle Cretaceous epoch, roughly 106 MYA.
This episode focuses on a flock of Leaellynasaura who are trying to survive the freezing winter and breed in the summer. The episode runs from end of winter to the next end of winter. At the beginning a female Koolasuchus eats a male Leaellynasaura which had died in the winter. During the summer a female dwarf allosaur hunts a male Leaellynasaura and a young Muttaburrasaurus. The Leaellynasaura usually escape, but during the noise and trampling and confusion caused by the Muttaburrasaurus migrating away north for the winter, the allosaur catches and eats the matriarch of the Leaellynasaura herd. A Koolasuchus is also on the hunt for the Leaellynasaura but the dinosaurs are too fast for the giant amphibians to catch even in the water. The episode ends in winter, as the Leaellynasaura have to settle down for another semi-hibernation period.
