Here's how dinosaurs could have survived mass extinction
The impact of the asteroid caused a crater 180 km wide and heated organic matter in rocks and ejected it into the atmosphere, forming soot in the stratosphere.
Asteroid behind extinction of dinosaurs also responsible for cooling Earth: Study
The study lends support to the hypothesis that the impact played a significant role in the Cretaceous-Paleogene extinction event that eradicated nearly three-quarters of Earths plant and animal species
