Feb 21, 2019 · Non-avian dinosaurs died out 66 million years ago in a cataclysm probably driven by a large asteroid impact. Now, two studies help to clarify how huge volcanoes erupting at the same time could...
Did Massive Volcanic Eruptions Drive Dinosaurs to Become Extinct?
Sep 13, 2022 · Did Massive Volcanic Eruptions Drive Dinosaurs to Become Extinct? A new study supports the theory that volcanoes — not asteroids — trigger the most extreme dinosaur mass extinction events. Large step-like formations of dark volcanic rock provide evidence of volcanic eruptions from millions of years ago. (Credit: Brenhin Keller)
