2 x 60 minutes / Produced for Discovery
Journey across time to a planet Earth that seems otherworldly and meet creatures that seem alien. Skies dominated by screeching pterodactyls, seas patrolled by freakish Anomalocaris (a carnivorous, seven foot long prawn) and the lands savaged by the saber toothed tiger. The prehistoric world s most terrifying and often awkward creatures are brought back to life. See how they hunted, how their incredible predatory tools evolved and how they ultimately disappeared.
