The most widely accepted theory is the asteroid impact. Other significant theories include volcanic activity and climate change.

66 million years ago, an asteroid struck Earth, causing massive environmental changes.

The Deccan Traps in India experienced extensive volcanic eruptions around the same time as the asteroid impact.

Long-term climate shifts may have contributed to dinosaur decline and extinction.

Pro tip: Theories are constantly evolving; new evidence can change our understanding of events from 66 million years ago.
