About 66 million years ago, an estimated 6-mile-wide (9.6 kilometers) object slammed into Earth, triggering a cataclysmic series of events that resulted in the demise of non-avian dinosaurs.
Now, scientists think they know where that object came from.
According to new research, the impact was caused by a giant dark primitive asteroid from the outer reaches of the solar system's main asteroid belt, situated between Mars and Jupiter. This region is home to many dark asteroids — space rocks with a chemical makeup that makes them appear darker (reflecting very little light) compared with other types of asteroids.
"I had a suspicion that the outer half of the asteroid belt — that's where the dark primitive asteroids are — may be an important source of terrestrial impactors," said David Nesvorný, a researcher from the Southwest Research Institute in Colorado, who led the new study. "But I did not expect that the results [would] be so definitive," adding that this might not be true for smaller impactors.
Clues about the object that ended the reign of non-avian dinosaurs have previously been found buried in the Chicxulub crater, a 90-mile-wide (145 km) circular scar in Mexico's Yucatan Peninsula left by the object's collision. Geochemical analysis of the crater has suggested that the impacting object was part of a class of carbonaceous chondrites — a primitive group of meteorites that have a relatively high ratio of carbon and were likely made very early on in the solar system's history.

Dinosaurism - modern religion. Dem bones ain’t bones.
Unfortunately for the God-denying atheistic evolutionists, in 1969 the amount of dust on the moon proved that the earth and its environs was only 10,000 years old.
It takes more faith to believe in evolution than the simple faith required to believe in Creation.
Dark rocks? Better not call them you-know-what heads.
I'm wondering if dinosaurs had high oxygen requirements, and the event reduced the Earth's O2 level for a while and they suffocated. It's one thing which would explain why all dinos everywhere, both land and sea dwellers, on all continents, died.
Avian dinosaurs would have needed extra lung capacity for flight, which would have allowed them to survive a lower oxygen level and feast on the carcasses of dead dinosaurs.
Let me see:
1. Climate change is going to kill us all;
2. COVID is going to kill us all;
3. A dark asteroid is going to kill us all.
So if we’re already doomed, why worry.
Asteroids come from the asteroid belt in outer space.
Who would have guessed?
Correction: One fourth (1.5 miles)
Unless you are a surfing fanatic...
Not all of them.

If you happen to be UNDER it, it doesn’t matter how big it is..................
“Asteroids come from the asteroid belt in outer space.”
Yep. Jupiter’s gravity occasionally sends hunks of rock from the asteroid belt our way. The only thing this study seems to have done is narrow it down to one part of the asteroid belt.
The dust from the event is believed to have denied sufficient light to support photosynthesis and thus most plant life died. With that, herbivorous dinos died off, and then the carnivorous ones who depended on them for food.
That doesn't explain all the non-dino species that did survive, which also included herbivores and carnivores.
Why ALL non-avian dinosaurs, the big ones, the small ones, in all sorts of ecological niches died. But alligators, insects, avian dinosaurs, etc lived.
Why aquatic dinosaurs all died off, but fishes, squids, sharks, etc all lived.
Well, if it’s a dark rock it needs to be removed as it will offend some of the wokes.....
