Feb 24, 2021 · This discovery painted an apocalyptic picture of dust from the vaporized asteroid and rocks from impact circling the planet, blocking out the sun and bringing about mass death through a dark, sustained global winter – all before drifting back to Earth to form the layer enriched in asteroid material that’s visible today.

Jul 12, 2011 · Yale University graduate student Stephen Chester admires a dinosaur bone he helped find just below fallout from an asteroid impact (dark layers). Tim Webster. What happened to the dinosaurs? For more than 100 million years, they ruled the world. Then, suddenly—poof—about 65 million years ago, they were gone.

May 18, 2014 · LOS ANGELES – The asteroid that wiped out the dinosaurs also caused a temporary but devastating “impact winter” — darkening the sky, cooling the Earth and inhibiting photosynthesis, new...

Feb 24, 2021 · Researchers believe they have closed the case of what killed the dinosaurs, definitively linking their extinction with an asteroid that slammed into Earth 66 million years ago by finding a key...

Feb 25, 2021 · Now, new research from the Free University of Brussels-VUB and Imperial College London has found a spike in concentrations of ‘space dust’ in the layers atop the Chicxulub crater, which correspond to the time of the dinosaurs’ demise and similar deposits around the world.

Sep 9, 2019 · As they report today in the Proceedings of the National Academy of Sciences, the dark layers reveal stunning details, including the sheer amount of material that piled up mere hours after the...

Aug 9, 2016 · When the asteroid plowed into the Earth, tiny particles of rock and other debris were shot high into the air. Geologists have found these bits, called spherules, in a 1/10-inch-thick...
