Glen Penfield

Glen Penfield is a geophysicist best known for his role in the discovery of the Chicxulub crater, a massive impact structure located on the Yucatán Peninsula in Mexico. This crater is widely accepted as the impact site of the asteroid that contributed to the Cretaceous–Paleogene (K–Pg) extinction event approximately 66 million years ago, which led to the mass extinction of non-avian dinosaurs and many other species.
