Scientists have long speculated that the demise of the dinosaurs some 66 million years ago was due to starvation triggered by a nuclear winter that followed a major asteroid impact. However, disturbing new research suggests the prehistoric megadeath may have come quicker and burned hotter.
A recent study published in the journal JGR Biogeosciences proposes that extreme heat and rampant fires may have played a major role in eradicating/burning to death land-based life, including the dinosaurs.
Scientists generally agree that when the six-mile-wide Chicxulub meteorite struck Mexico’s Yucatan Peninsula at the end of the Cretaceous Period, it vaporized huge quantities of rock that condensed into tiny droplets. In 2023, at the Tanis fossil site in North Dakota, researchers identified a deposit layer above the spherules. Researchers believe this fine dust cloud could have functioned as a kind of prehistoric insulating blanket, trapping thermal radiation on Earth’s surface and igniting worldwide wildfires.
“With the dust cloud trapping thermal radiation, it was like the surface, and everything on it was being charbroiled – and that’s what killed the dinosaurs and all the other animals,” lead author Brandon Johnson, a planetary scientist at Purdue University, said in a statement.
So, what they're saying is, the meteorite didn't kill them all, but it did. Okay, I'll buy that theory. Jeez, people get paid to come up with the craziest shit, don't they?
I surrender...
