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.
In addition to the 180 km (110 mi) Chicxulub crater, there is the 24 km (15 mi) Boltysh crater in Ukraine (65.17 ± 0.64 Ma), the 20 km (12 mi) Silverpit crater in the North Sea (59.5 ± 14.5 Ma) possibly formed by bolide impact, and the controversial and much larger 600 km (370 mi) Shiva crater.
The massive Chicxulub asteroid may have had some help from a second “sibling” asteroid, according to new research. TWO Asteroids May Have Killed Off the Dinosaurs, Scientists Say Skip to main ...
"So the one that killed the dinosaurs is really special in two ways — by what it did, and also by where it originated." This apocalyptic object is what created the Chicxulub crater on Mexico’s ...
This impactor excavated the Chicxulub crater that is 180 km (110 mi) in diameter. With an object this size, dust and debris would still be ejected into the atmosphere even if it hit the ocean, which is only 4 km (2.5 mi) deep. [3] An asteroid, meteor, or comet would remain intact through the atmosphere by virtue of its
The asteroid that killed most dinosaurs 66 million years ago left behind traces of its own origin. Researchers think they know where the Chicxulub impactor came from based on levels of ruthenium.
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 ...
