Introduction

The Cretaceous-Paleogene (K-Pg) extinction event, also known as the K-T extinction, marked the end of the dinosaur era and the beginning of a new chapter in Earth's history.

The Asteroid Impact Theory

The most widely accepted theory is that the extinction was caused by the impact of a large asteroid near the Yucatan Peninsula in Mexico.

Other Contributing Factors

Other factors that may have contributed to the extinction include volcanic activity, climate change, and sea level fluctuations.

The Aftermath

The extinction event led to the extinction of approximately 76% of plant and animal species on Earth, paving the way for the rise of mammals.
