But that wasn't the worst. Long before the asteroid, long before Tyrannosaurus rex, and long before life dominated the land, Earth suffered a silent catastrophe that wiped out more than half of all species on the planet. In this Ancient Planet documentary, we travel back to the Late Ordovician, about 445 million years ago, to discover one of the most devastating and least-known mass extinctions in history. We'll explore a world dominated by shallow seas, trilobites, giant cephalopods, primitive corals, sea scorpions, and creatures that seem to have come from another planet. Next, we'll see how extreme glaciation, falling sea levels, oxygen depletion in the oceans, and a series of brutal climate changes brought life to the brink of collapse. What will you find in this documentary? ► The Ordovician World Before the Catastrophe ► The Great Ordovician Radiation and the Explosion of Marine Life ► Trilobites, Endocerids, Eurypterids, Conodonts, and Radiodonts ► The Hirnantian Glaciation and the Freezing of Gondwana ► The Fall in Sea Level and the Destruction of Shallow Seas ► The Double Blow of Extinction: Freezing, Melting, and Oceanic Anoxia ► The Groups That Disappeared and Those That Managed to Survive 👉 Subscribe here:    / @planeta_antiguo   📸 Instagram:   / planeta.antiguo   📩 Contact: [email protected] ⚠️ This documentary has an educational and informational purpose.
