Dinosaur-Killing Meteorite Identified as Rare CO Chondrite

A team of researchers from the University of British Columbia, Paris, Brussels, and Vienna has made a groundbreaking discovery in the field of asteroid science. By analyzing nickel isotopes in material left behind by the Cretaceous-Paleogene impact, they have identified the rare meteorite that killed the dinosaurs as a CO chondrite, a type of carbonaceous meteorite.

Being impacted by such a rare, distant projectile really underscores how unlucky the dinosaurs were.

This finding is significant because CO chondrites contain much less sulfur than other types of meteorites, which means that the sulfur released by the impact was unlikely to have been the primary cause of the mass extinction event. Instead, the researchers suggest that the enormous quantities of fine debris blasted into the atmosphere may have played a dominant role.

The discovery is a testament to the dedication of scientists working on this project, who have spent years gathering samples and conducting precise measurements. The study's lead author, Dr. Philippe Claeys, notes that the impact was an unlikely event, with the dinosaurs being struck by a rare, distant projectile.

The identification of the CO chondrite meteorite is a major breakthrough in our understanding of the asteroid that caused the extinction of the dinosaurs. It also highlights the importance of continued research in this area, as scientists continue to uncover new insights into the history of our planet.

The study's findings have significant implications for our understanding of the asteroid that caused the mass extinction event. By identifying the type of meteorite that struck the Earth, scientists can gain a better understanding of the conditions that led to the impact and the effects it had on the environment.
