Fossils are revealing disturbing details about Earth’s deadliest day.

For years, scientists believed they understood how the dinosaurs disappeared. A massive asteroid struck Earth, the climate collapsed, and the age of dinosaurs slowly faded away. But new fossil discoveries are forcing researchers to rethink that story. At several extraordinary sites, the ground appears to have captured the exact moments when the catastrophe began. What these fossils show is not a gradual decline, but a scene of sudden chaos, violent forces, and animals caught in the middle of a disaster unfolding in real time.
