Ilustração de Chicxulub Impact

Asteroid impact. Illustration of a large asteroid colliding with Earth on the Yucatan Peninsula in (what is modern day) Mexico. This impact is believed to have led to the death of the dinosaurs some 65 million years ago. The impact formed the Chicxulub crater, which is around 200 kilometres wide. The impact would have thrown trillions of tons of dust into the atmosphere, cooling the Earths climate significantly, which may have been responsible for the mass extinction. A layer of iridium- rich rock, known as the K pg boundary, is thought to be the remnants of the impact debris. Here, the impact is seen from the ocean. The animal in silhouette is a mosasaur, an extinct marine predator.
