The Sabre-Toothed Monsters That Ruled Earth 250 Million Years Ago

Before the first dinosaur ever drew breath, the Earth was already ancient. Journey back 250 million years to the Permian — a world with a single supercontinent, one vast ocean, forests with no grass and no flowers, and rulers that were not dinosaurs at all, but our own distant cousins. Then came the Great Dying: the closest life has ever come to ending completely. New episodes explore each lost world of the prehistoric past.
