Standing on the Deccan Traps (IMAGE) Princeton University Caption Princeton geoscientists Blair Schoene and Gerta Keller led an international team of researchers who have assembled the first high-resolution timeline for the massive eruptions in India's Deccan Traps, determining that the largest eruption pulse started less than 100,000 years before the mass extinction that killed the (non-avian) dinosaurs. Here, researchers stand atop a massive basalt flow of the Mahabaleshwar Formation of the Deccan Traps at the Sinhagad Fort, located on a dramatic cliff in the Sahyadri Mountains.
