Summary:

- A new study suggests that a meteorite called S2 may have been responsible for the mass extinction event that wiped out the dinosaurs around 66 million years ago.
- The researchers analyzed the chemical composition of the S2 meteorite and found that it matches the Chicxulub impactor, the large asteroid that is believed to have caused the Cretaceous-Paleogene (K-T) extinction.
- The findings provide further evidence that the Chicxulub impact was the primary driver of the mass extinction event, which paved the way for the rise of mammals and the evolution of modern life on Earth.
