Dinosaur Fossil Provides Clues About Meteor Extinction
A triceratops fossil recently found in Montana may give scientists further evidence as to what drove the dinosaurs to extinction.
While some scientists believe that dinosaurs had already been extinct when the meteorite hit 65 million years ago, this discovery adds to the growing evidence that dinosaurs were still around. According to the Huffington Post, those that criticize the asteroid theory cite the absence of fossils below the Cretaceous-Tertiary boundary in the earth, believed to have formed after the asteroid hit. The triceratops horn is a big piece of evidence because it was discovered five inches below that boundary.
Yale graduate student and lead author on the research study, Tyler Lyson, told the Huffington Post, “The fact that this specimen was so close to the boundary indicates that at least some dinosaurs were doing fine right up until the impact.”
