A Cosmic Coincidence: The Rare Meteorite that Wiped Out Dinosaurs The discovery of a CO chondrite meteorite, one of the most primitive and untouched materials in our Solar System, has been identified as the culprit behind the mass extinction of dinosaurs 66 million years ago.
This finding sheds new light on the K Pg (Cretaceous Paleogene) extinction event, which wiped out 75% of Earth's species in a single cataclysmic strike.
The researchers who made this breakthrough used advanced nickel isotope analysis and international collaboration between teams at the University of British Columbia, Paris, Brussels, and Vienna.
