Ancient Earth (2017)

Episode Overview

During the Permian period, Earth was home to an array of incredible species. Significant geological transformations created conditions that enabled life to flourish both on land and in the oceans, giving rise to fierce predators like the saber-toothed Gorgonopsid and the fearsome 40-foot shark known as Helicoprion. However, this flourishing era was destined to come to an end.
