WOW! Now that is a really interesting theory: a giant asteroid triggers a massive oil fire that blocks sunlight with soot. What a horrific time to be alive if that theory is right.

“Sixty six million years ago, the dinosaurs suddenly disappeared, along with most of the species on the planet. The extinction occurred at precisely the same time that a giant asteroid struck the Earth. The fact that the two events happened at the same time makes it all but certain that the asteroid wiped out the dinosaurs, but just how did that extinction happen? Was it dust, shot into the sky, blocking out the sun? Acid rain produced by sulphur vaporised during the impact? An inferno of hot debris?
A new study may get us closer to solving this mystery. The asteroid struck the Yucatan Peninsula, a region with vast quantities of crude oil buried underground. New data shows that the burning of the oil produced billions of tons of soot, enough to dim the sun for years and lead to a decade of global cooling.
The Cretaceous-Paleogene (K-Pg) extinction event was severe, wiping out over 75% of all species, including not just dinosaurs but also many birds, mammals, snakes, lizards, plants, and even insects. It was global, hitting all continents and all oceans. And it was rapid, with species seeming to vanish overnight.”
