The Triassic Period (As We Understand It) | Documentary for Sleep

Tonight we travel to the Triassic Period, the strange recovery era after Earth’s worst extinction: the Permian–Triassic “Great Dying.” In a world of Pangaea, brutal heat, collapsing ecosystems, and toxic seas, life rebuilds itself from near-total ruin—slowly, quietly, and relentlessly. We’ll explore how one supercontinent reshaped climate and evolution, why the planet experienced the mysterious Coal Gap and the Fungal Spike, how early forests returned, and how new dynasties rose: archosaurs (crocodile-line and bird-line), the earliest dinosaurs, nocturnal cynodonts on the road to mammals, and the first ocean and sky conquerors—marine reptiles, ichthyosaur leviathans, and pterosaurs. We’ll also pass through the climate upheaval of the Carnian Pluvial Episode, when persistent rains helped rewrite the balance of power across the planet. This is a calm, slow-paced sleep documentary designed for relaxation—scientifically grounded, atmospheric, and immersive.
