Abstract

Researchers have determined that the asteroid responsible for the extinction of the dinosaurs 66 million years ago, known as the Chicxulub impactor, was a carbonaceous chondrite meteorite. This type of meteorite is rare and ancient, forming beyond the orbit of Jupiter. The finding is supported by the discovery of trace amounts of ruthenium metal in geological layers around the world that match the isotopes found in carbonaceous chondrite meteorites. The study also suggests that the impactor's carbon-rich composition may have contributed to the severity of the extinction event. [Extracted from the article]
