1Nuevo Amanecer
Hace 49 millones de años, en lo que hoy es Alemania, extensos bosques tropicales que compartía con otros continentes se extendían con un trópical clima que resguardaba maravillosas criaturas. El foco de este primer capítulo, nos enfocaremos en una hembra Leptictidium, un mamífero pequeño con una flexible trompa que busca alimento para sí misma y para sus pequeños y que ha sobrevivido desde la extinción de los dinosaurios. Leptictidium esta en un mundo que comparte con el Propalaeotherium, un primitivo caballo del tamaño de un gato. Y ambos viven en un mundo lleno de peligros como el Ambulocetus; una rara bestia que camina en tierra y es antecesora de las ballenas... y la más letal es Gastornis: un ave no voladora tan grande como un hombre que come caballos, pero cuya descendencia es doblegada por el depredador menos pensado: hormigas.
2Ballena Asesina
Es el final del eoceno, y grandes cambios climáticos han surgido a consecuencia del enfriamiento gradual de la Antártida. Los descendientes del Ambulocetus han evolucionado para habitar las aguas, y se han convertido en la primera ballena del mundo. La Basilosaurus, de 18 metros y con fauces llenas de dientes filosos. En este capítulo seguiremos a una hembra embarazada que lucha por buscar comida para sí y su feto en un mundo en el que el cambio climático amenaza con llevarles a la extinción.
3Land of Giants
It is now the Oligocene period, and the massive change in climate claimed 1 in every 5 species. The great tropical forests and plains that dominated the Eocene have shrunk, hanging on in the equatorial regions. In Mongolia, a seasonal desert now dominates the land, populated with some of the largest beasts ever to roam its landscape since the days of the dinosaurs. The are Hyenadon, predators as big as modern rhinos; Entelodonts, mean spirited pigs just as big; and largest of all, the massive Indricotheres, a species of rhino that was the biggest land mammal ever!
4Next of Kin
The Pliocene has arrived, and the world is taking on its familiar shape. In the Great Rift Valley of Africa, the animals are taking familiar forms, though some exotic forms are wondering around with animals modern man would be familiar with. It is here that a new species of ape has evolved, one that will one day evolve into the most powerful animal ever seen.
5Sabre Tooth
South America is a land time forgot, with giant birds, the last of a trunked, hoofed herbivore, huge sloths, and giant armadillos. But the isolation of this continent has ended; and land bridge now connects South America with North America. With it has come a new species of predator; Smilodon, the infamous saber-toothed ""tiger"". But life here is no easier for the largest of all cats, especially for Half Tooth, a large male Smilodon. Having been usurped by two other males for breeding rights with a clan of females, Half Tooth struggles to survive on his own, a daunting prospect that claims many a lone male's life. But fate has a different agenda in store for Half Tooth.
6Mammoth Journey
The Ice Age has arrived, putting life in the freezer. It is at this time when great herds of Woolly Mammoths live on the plains of what will eventually be the North Sea. As winter arrives, the Mammoth herds head south, moving to greener pastures. It is not an easy journey, especially for the young. Predators are everywhere, and the most dangerous of all are two species of humans that share the Ice Age environments of the mammoths.
