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. [13] The impact spewed hundreds of billions of tons of sulfur into the atmosphere, producing a worldwide blackout and freezing temperatures which ...
The Chicxulub event – the giant impact that ended the reign of non-avian dinosaurs, clearing the way for mammalian life to rise – was triggered by an asteroid from a region of the Solar System out past the orbit of Jupiter, the cold, dark outer limits, far from the Sun's light and warmth.
About 66 million years ago, an asteroid slammed into the sea just off Mexico’s Yucatán Peninsula, forming the Chicxulub crater. That powerful impact may have triggered a mass extinction event ...
The buried crater, over 90 miles in diameter, was created when a massive asteroid struck the planet 66 million years ago and brought a calamitous end to the reign of dinosaurs.
It was tens of miles wide and forever changed history when it crashed into Earth about 66 million years ago. The Chicxulub impactor, as it’s known, was a plummeting asteroid or comet that left behind a crater off the coast of Mexico that spans 93 miles and goes 12 miles deep.
The prime suspect in the extinction of the dinosaurs was no ordinary asteroid, researchers have revealed. Comparisons between the chemical record left behind by the strike 66 million years ago and known meteorite samples suggest that the Cretaceous asteroid was a carbonaceous chondrite.
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.
UPDATE: Today, scientists published their first results from a drilling expedition into Chicxulub crater, the buried remnants of an asteroid impact off the Yucatán Peninsula in Mexico that killed off the dinosaurs 66 million years ago.
An asteroid smashed into the Yucatán Peninsula 66 million years ago, killing some 75 percent of life on Earth, including all non-avian dinosaurs.
Sixty-six million years ago, an asteroid struck eastern Mexico and wiped out the dinosaurs. Now scientists have a better idea of what that looked like.
