L’impact de Chicxulub
🔸 Il y a environ 66 millions d'années, un impact d'astéroïde a anéanti les trois quarts de toutes les espèces végétales et animales sur Terre, détruisant notamment les dinosaures.

💁🏻♀️ 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.

New research on #Chicxulub suggests the dinosaur-killing impact also formed a long-lived underground hydrothermal system sustaining life-friendly conditions for at least 8 million years, far longer than previously thought. Based on #IODP #Exp364: https://www.nature.com/articles/s43247-026-03618-5

Study reveals dinosaur-extinction meteorite created long-lived habitat for microbial life.
A team of international researchers has uncovered new evidence that the Chicxulub meteorite impact, long known for causing the extinction of the dinosaurs, also created an underground environment that supported life for millions of years longer than previously thought.

The Chicxulub impact was a quick and catastrophic event with lasting consequences. Not talking about the thing with the dinosaurs - it drove significant hydrothermal activity for 8 million years across the entire region.

The Chicxulub impact signature in East Asia.
The Cretaceous-Paleogene boundary is defined by an asteroid impact at 66 million years ago at Chicxulub, Mexico. Despite extensive documentation worldwide, this boundary has not been clearly identified in East Asia, leaving a geographic gap in evaluating the global extent of impact records.

#Evolution didn’t wait long after the dinosaurs died
Marine ecosystems began recovering within just a few thousand years after the asteroid strike
The findings invite a rethink of how rapidly evolution can rebuild biological diversity — not just as it did after the #Chicxulub asteroid struck Earth 66 million years ago, but perhaps also today and into the future as #climatechange and other human pressures accelerate the pace of ecological upheaval.

Today in "What the hell are you talking about Avaris?" I noticed something weird about the US river systems... namely that a lot of them spread out like cracks from the Gulf of Mexico. Not only that but the Mississippi and Missouri rivers lead up to some of the best dinosaur dig sites in the US... which got me wondering if these paths have any relation to Chicxulub or if it's pure coincidence.

Just spotted this dramatic depiction of the ring of #cenotes caused by the #Chicxulub impact in #Yucatan - https://en.wikipedia.org/wiki/Cenote#Chicxulub_crater - in the 2nd episode "Forests of the Maya" of the 2017 BBC documentary series "Mexico: Earth’s Festival of Life": didn't know that the pattern was that rich and cleanly delineated. Is there a scientific publication that shows it with similar clarity?

Brought out from a discussion elsenet: would Earth now be warm enough to support large, #nonavian #dinosaurs today? This is a fair question, because as bad as global warming is—and it's going to get worse—we're still nowhere near the hottest times of the #Mesozoic.
The answer is, it was *generally* warmer than the present day, but #global #temperatures went up and down considerably, as you'd expect over such a long stretch of time—about 175 million years from the first dinosaurs to the #Chicxulub impact. Dinosaurs as a #clade did fine the whole way through, although of course with plenty of various groups dying out in the meantime.
Also, the planet has always had warmer and cooler regions. Many large dinosaurs lived comfortably in polar regions that had #climates comparable to the cooler parts of the temperate zones today. The idea that non-avian dinosaurs exclusively inhabited steaming jungles or baking deserts has been embedded by generations of paleoart, but it's just wrong. If the impact hadn't happened, they'd still be thriving.
That being said, #sauropods in particular seemed to prefer warmer environments, so their range might be a lot more limited now than it was then, and it's possible the ice age(s) would have finished them off. Other famous giants like #tyrannosaurs, #ceratopsians, and #hadrosaurs would still be widespread, and smaller ones like #dromaeosaurs ("raptors") would be as numerous as coyotes and wildcats are in our world.

The discovery of #Chicxulub, which supports the dino-killing asteroid theory is a fun read. A non-academic and a journalist announced a result, but all the leading academics were not paying attention. Eventually their validation was accepted but took a decade to be heard.
https://en.m.wikipedia.org/wiki/Chicxulub_crater#Discovery
> Penfield also recalled that part of the motivation for the name was "to give the academics and NASA naysayers a challenging time pronouncing it" after years of dismissing its existence.[
