The authors, William F. Bottke, David Vokrouhlický, and David Nesvorný, argued that a collision in the asteroid belt 160 million years ago between a 170 km (110 mi) diameter parent body and another 60 km (37 mi) diameter body resulted in the Baptistina family of asteroids, the largest surviving member of which is 298 Baptistina.
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 ...
A study reveals the chemical makeup of the Chicxulub asteroid that collided with Earth and resulted in the extinction of nearly all dinosaurs 66 million years ago.
The finding suggests that the impact occurred 200,000 to 300,000 years before the K-Pg extinction, a period far too large for the two to be correlated. [ 14 ] [ 15 ] This, however, contrasts the range of 33,000 years determined by Paul Renne in 2015, [ 19 ] [ 20 ] as well the more recent assertion that a tsunami generated by the impact created ...
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 ...
The most infamous asteroid impact occurred 66 million years ago, when a six-mile-wide space rock triggered a global winter, wiping out the dinosaurs and 75 percent of all species. By contrast ...
As originally proposed in 1980 [9] by a team of scientists led by Luis Alvarez and his son Walter, it is now generally thought that the K–Pg extinction was caused by the impact of a massive asteroid 10 to 15 km (6 to 9 mi) wide, [10] [11] 66 million years ago causing the Chicxulub crater, which devastated the global environment, mainly ...
It was, to put it mildly, a bad day on Earth when an asteroid smacked Mexico's Yucatan Peninsula 66 million years ago, causing a global calamity that erased three-quarters of the world's species ...
