Dinosauric demise

Abstract

For more than a decade, many scientists have theorized that the disappearance of the dinosaurs may be due to the collision of a huge asteroid with Earth 65 mya. However, many gaps have persisted in the theory. Now NASA scientists offer a detailed explanation of how the impact may have led to the extinction of the dinosaur. In a recent issue of Earth and Planetary Science Letters, a team of scientists from the Jet Propulsion Laboratory's Earth and Space Sciences Division in Pasadena, Calif., write that the location of the impact was key.
