NEW YORK — The American Museum of Natural History (AMNH) in New York City has opened a new exhibition that takes a multidisciplinary perspective on the asteroid strike that ended the Cretaceous period and killed all the non-avian dinosaurs. The exhibit — aptly called “Impact” — chronicles what was, in the words of AMNH curator of paleontology Roger Benson, Earth’s “worst day of the last half-billion years.”

Many animals, including large dinosaurs, were buried in ash — though some were able to escape by digging underground or diving underwater.

The tremendous impact also flung a mushroom cloud of ash and dust into the atmosphere, eventually shrouding the planet in a cold gloom. Tiny glass beads rained down as far away as Wyoming. At the same time, the impact triggered landslides, earthquakes and tsunamis around the world.
