Dinosaurs became extinct approximately 66 million years ago, mainly due to a mass extinction event caused by a catastrophic asteroid impact in the Yucatán Peninsula, which dramatically changed the environment. This impact likely blocked sunlight, resulting in climate shifts and widespread wildfires. Additionally, volcanic eruptions in what is now India may have contributed to long-term environmental changes that further stressed ecosystems. Although some evidence indicates that dinosaurs were already experiencing decline, the swift alterations from these events sealed their fate. Other theories suggest factors like disease and gradual environmental changes, but the asteroid impact is still the primary explanation.
