The K-Pg Extinction Event: A Brief Refresher
The K-Pg extinction event, which occurred about 66 million years ago, marks one of the most significant moments in Earth’s history. This cataclysmic event wiped out approximately 75% of plant and animal species on our planet, including the non-avian dinosaurs.
Scientists believe a massive asteroid impact was the main culprit behind this mass extinction. The collision caused global climate changes, including widespread fires, darkness, and rapid cooling followed by long-term warming. These drastic environmental shifts proved too much for many species to handle.
The K-Pg extinction event (formerly known as the K-T extinction) gets its name from the boundary between the Cretaceous (K) and Paleogene (Pg) periods in the geological timescale. This boundary is visible in rock layers around the world, often marked by a thin layer of clay rich in iridium, an element rare on Earth but common in asteroids.
