The Rock That Changed Everything
Why did dinosaurs go extinct?
For 165 million years, dinosaurs ruled the planet. T. rex hunted in forests. Triceratops grazed in herds. Pterosaurs soared overhead. Then, 66 million years ago, they vanished — all of them, everywhere, almost overnight. What could possibly wipe out creatures that had dominated Earth for longer than mammals have even existed?
The answer came from space. A rock the size of Mount Everest — an asteroid about six miles wide — was hurtling toward Earth at 45,000 miles per hour. The dinosaurs had no idea it was coming. Nothing could have stopped it.
