The Devonian: Monster Fish, First Forests & Legged Animals | Documentary for Sleep with Rain Sounds

Long before the dinosaurs, a fish the size of a small car, armoured in bone and armed with self-sharpening jaws, hunted the warm seas of the Devonian. On land, the first forests were rising. This is a slow, calm documentary about that world, told over the sound of gentle rain, for falling asleep to. The narration runs for about 53 minutes, then the rain and soft music fade out slowly over a few more minutes, so the ending never wakes you.
