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.

Around 66 million years ago, an asteroid larger than Mt. Everest ripped through the atmosphere of Earth, striking our planet at the Yucatán Peninsula, on the southeastern coast of Mexico.
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 ...
A study of 29 fossil sites in Catalan Pyrenees of Europe in 2010 supports the view that dinosaurs there had great diversity until the asteroid impact, with more than 100 living species. [135] More recent research indicates that this figure is obscured by taphonomic biases and the sparsity of the continental fossil record.
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 ...
This programme follows the trail of clues leading to the extinction of non-avian dinosaurs, 65 million years ago. Iridium and shocked quartz found at the K–T boundary (Cretaceous–Paleogene boundary) are investigated which leads to the belief that an asteroid strike on the Yucatán Peninsula was responsible for the extinction.
The study shows that the asteroid, while having a severe initial impact, did not immediately kill off the dinosaurs - instead slowly killing them off over a few years.
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.
