66 Million Years Ago: What Really Happened to the Dinosaurs? | Hindi Documentary

66 million years ago, Earth changed forever. 🦖☄️ For millions of years, dinosaurs dominated Earth's terrestrial ecosystems. Then, an asteroid struck near what is now the Yucatán Peninsula in Mexico. What followed was far bigger than a single impact. Massive shockwaves, atmospheric debris, reduced sunlight and major environmental disruption contributed to the end-Cretaceous mass extinction, one of the most significant extinction events in Earth's history. But the story has an unexpected ending. Not all dinosaurs disappeared. Birds are living dinosaurs—and their lineage survived.
