About the Author

Dr. Gerta Keller is a renowned paleontologist and professor emerita at Princeton University, whose groundbreaking research has reshaped our understanding of Earth's cataclysmic events. With decades of fieldwork in diverse locales from the Mexican Gulf to the Indian Deccan Traps, she has challenged conventional narratives on mass extinctions, emphasizing volcanic activity and gradual environmental shifts over sudden impacts. Keller's meticulous scientific approach, blending geology, paleobiology, and stratigraphy, has earned her international acclaim and sparked debates in academic circles. In her acclaimed book, The Last Extinction: The Real Science Behind the Death of the Dinosaurs, she presents compelling evidence against the asteroid-only theory, advocating for a multifaceted view of the Cretaceous-Paleogene boundary that continues to influence contemporary paleontological discourse.
