  1. 💁🏻‍♀️ 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.

  2. 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.

  3. #African #FossilFriday

    Southern #Africa is one of the most important places in the world for understanding the #Permian, the period that ended with the largest #MassExtinction in #Earth's history. The valleys of the #Luangwa and #Zambezi in #Zambia 🇿🇲 are particularly rich in Permian fossils, including this #gorgonopsian on display at the #UniversityOfWashington's #BurkeMuseum. These impressive animals are #therapsids, close relatives of mammals and perhaps the first #sabertooths.
