Artist's impression of the asteroid slamming into tropical, shallow seas of the sulfur-rich Yucatán Peninsula in what is today Southeast Mexico. [13] The aftermath of the asteroid collision, which occurred approximately 66 million years ago, is believed to have caused the mass extinction of non-avian dinosaurs and many other species on Earth.

A six-mile-long asteroid, which struck Earth 66 million years ago, wiped out the dinosaurs and more than half of all life on Earth.The impact left a 124-mile-wide crater underneath the Gulf of ...
Scientists may have finally found where the object that wiped out the dinosaurs came from. ... They also looked at samples from five other asteroid impacts taken in the last 541 million years, as ...
Luis Walter Alvarez, left, and his son Walter, right, at the K–T Boundary in Gubbio, Italy, 1981. The Alvarez hypothesis posits that the mass extinction of the non-avian dinosaurs and many other living things during the Cretaceous–Paleogene extinction event was caused by the impact of a large asteroid on the Earth.
Dinosaurs had long ruled the land but, aside from their bird lineage, were wiped out following the impact, as were the flying reptiles called pterosaurs, the large marine reptiles and other sea ...
Scientists think they've found the origin of the asteroid that wiped out the dinosaurs. It could help prevent a future mass extinction on Earth. Jenny McGrath. Updated September 5, 2024 at 7:44 AM.
The Cretaceous–Paleogene ("K-Pg" or "K-T") extinction event around 66 million years ago wiped out all non-avian dinosaurs and many other species. Proposed by Luis and Walter Alvarez , it is now widely accepted that the extinction was caused by a huge asteroid or bolide that impacted Earth in the shallow seas of the Gulf of Mexico , leaving ...
The asteroid responsible for our last mass extinction 66 million years ago — wiping out the dinosaurs — originated from the far reaches of our solar system, unlike most asteroids that have ...
