💁🏻‍♀️ TIL: ☄️🔥 A recent study from #Purdue suggests fine dust from the #Chicxulub impact trapped heat in the upper #atmosphere, effectively charbroiling exposed organisms within hours.

Post-impact dust would have delivered 17 times the lethal #radiation dose for #humans, igniting #grass and #lichen across the #planet.

Every mammal alive today, including you, is a descendant of the small, scared creatures that somehow clawed through those years of darkness. The cataclysm that ended the dinosaurs is, in the most literal sense, the reason you exist.
