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.

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 ...
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.
Researchers report that the Cretaceous Chicxulub asteroid impact that resulted in the extinction of non-avian dinosaurs 66 million years ago, also rapidly acidified the oceans producing ecological collapse and long-lasting effects on the climate, and was a key reason for end-Cretaceous mass extinction.

When an asteroid between 10 and 15 kilometres wide struck Mexico’s Yucatan Peninsula around 66 million years ago, its impact caused devastation, setting off wildfires, earthquakes, and ...
Fine dust thrown up into Earth’s atmosphere after an asteroid strike 66 million years ago blocked the sun to an extent that plants were unable to photosynthesize, a new study has found.
Alternatively, interpretation based on the fossil-bearing rocks along the Red Deer River in Alberta, Canada, supports the gradual extinction of non-avian dinosaurs; during the last 10 million years of the Cretaceous layers there, the number of dinosaur species seems to have decreased from about 45 to approximately 12. Other scientists have made ...
An asteroid an estimated 6-9 miles (10-15 km) wide slammed into Mexico's Yucatan Peninsula 66 million years ago, triggering a global cataclysm that eradicated about three-quarters of the world's ...
