Antarctica, 106 million years B.C. In the Mid Cretaceous, Antarctica is much warmer than in modern times and covered in lush rain forests inhabited by dinosaurs like the tiny herbivore Leaellynasaura and by relics like the giant amphibian Koolasuchus. Some, like the predatory Allosaurus and giant herbivore Muttaburrasaurus, migrate from the warmer Australia in the summer. Leaellynasaura, however, hibernates during the winter, which is a cold, dark night lasting several months. This episode depicts one year in the life of a clan of Leaellynasaura plagued by territorial competition, egg thieves and predators. Written by

Dawn over a silent forest a few hundred miles away from the South Pole. It is the end of months of total darkness, and as the sun's rays filter down through the trees, they reveal a cold harsh world.
