Researchers just uncovered more about the asteroid that killed the dinosaurs 66 million years ago
Scientific analysis of nickel fingerprints has identified the dinosaur-extinguishing Chicxulub impactor as a rare 'oddball' meteorite.
Where it stands
Researchers have identified the specific class of meteorite responsible for the extinction event 66 million years ago. The discovery centers on the composition of the asteroid, which experts are now classifying as an unusual, rare space rock rather than a common type.
Coverage from outlets including The University of British Columbia, The Independent, and The Yucatan Times emphasizes the use of nickel fingerprints to determine the object's makeup. Reports from Sci.News, Discover Magazine, and ZME Science highlight how these chemical signatures clarify the nature of the impactor.
Future updates will likely focus on how these specific chemical properties influenced the environmental impact of the collision. Coverage does not yet specify how this finding will alter existing models of the mass extinction event.
