Rare CO Chondrite Meteorite Identified as Dinosaur-Killing Impactor
Scientists have determined that the meteorite responsible for the mass extinction of dinosaurs 66 million years ago was a rare CO chondrite. Researchers used advanced nickel isotope analysis to match the space rock's chemical signature to the catastrophic impact event. The asteroid struck Earth and formed the Chicxulub crater, triggering conditions that wiped out the majority of life on the planet. The rarity of this type of meteorite underscores how unlikely, yet devastating, the collision was for dinosaurs and other species.
