Fall asleep as we drift back more than four hundred million years to the Ordovician world — a time when life thrives in warm, shallow seas… and then faces one of Earth’s first great mass extinctions.
As climates shift and ice spreads across the ancient supercontinent of Gondwana, sea levels fall, habitats collapse, and entire ecosystems change faster than life can adapt.
In this slow, calm, sleep-friendly documentary, we explore what scientists know about the Ordovician–Silurian extinction: the clues preserved in fossils, the fingerprints of ancient glaciers, and the ocean chemistry changes that may have pushed marine life to the edge.
This video is created for educational purposes to explore scientific ideas in a peaceful, sleep-friendly format.
