Researchers Point to the Demise of the Dinosaurs
The idea that a comet or asteroid impact led to the downfall of the dinosaurs has been around for years. Now, Paul Renne and colleagues report in Science that they’ve narrowed down the timing of that collision. It’s practically simultaneous with dinosaur extinction.
Paul Renne is director of the Berkeley Geochronology Center and professor in residence in the Department of Earth and Planetary Science at U.C. Berkeley in Berkeley, California.
