What really killed the dinosaurs 66 million years ago?
The dinosaur extinction is one of the biggest mysteries in Earth’s history.
In this video, we explore the real cause of the dinosaur extinction and break down the biggest scientific theories behind one of the most devastating events in Earth’s history.
From the Chicxulub asteroid impact to the massive volcanic eruptions of the Deccan Traps, we uncover how a chain of catastrophic events may have wiped out the dominant species on the planet.
You’ll discover what Earth looked like before the extinction, why ecosystems were already unstable, and how this global disaster reshaped life — eventually leading to the rise of mammals and humans.
