A triceratops fossil may be key evidence in proving that a massive impact wiped out the dinosaurs.
The discovery was made at Montana's Hell Creek Formation and is the youngest dinosaur ever found, it dates back to a time so close to the mass extinction that it suggests the dinosaurs didn't die out gradually but were wiped out by a sudden cataclysmic event.
By studying the region's geological layers, the scientists can see how dinosaurs suddenly disappeared after the catastrophic event, which Lyson and many other experts believe was a meteorite strike that directly hit Earth at Mexico's Yucatan Peninsula.
