Total Extinction: When the Sky Fell on Earth

Travel back 66 million years to witness the most catastrophic day in Earth's history—when a mountain-sized asteroid slammed into our planet and changed the course of evolution forever. This is the story of the Great Dying, the moment when the age of dinosaurs ended in fire, darkness, and unimaginable devastation.
For over 160 million years, dinosaurs ruled Earth as undisputed masters. From the mighty Tyrannosaurus rex to the armored Triceratops, these titans dominated every ecosystem on the planet. But their reign was about to end in the most dramatic way imaginable. When the Chicxulub asteroid struck the Yucatan Peninsula, it released energy millions of times greater than all nuclear weapons combined, triggering global firestorms, massive tsunamis, and a deadly impact winter that plunged the world into darkness.
This documentary explores the science behind the extinction event that wiped out three-quarters of all life on Earth. We examine how the asteroid impact destroyed food chains, turned lush forests into funeral pyres, and created an endless night that lasted for months or even years. Discover how tiny mammals hiding in burrows and small feathered dinosaurs—the ancestors of modern birds—managed to survive when the giants could not.
Through cutting-edge paleontology and fossil evidence, we reconstruct the horrifying final days of the Mesozoic Era. From the moment of impact to the slow recovery that took millions of years, this is the complete story of how one cosmic rock rewrote the fate of our planet and paved the way for the rise of mammals—and eventually, humanity itself.
The extinction of the dinosaurs wasn't just an ending. It was the beginning of our world. Without this cataclysm, humans might never have existed. This is the story of destruction, survival, and the incredible resilience of life itself.
