Researchers have uncovered fossilised evidence of a 66 million year old asteroid impact, including fish with hot glass beads lodged in their gills from raining debris.
The site was found in Tanis, North Dakota, and shows that the fossilized fish died soon after the asteroid hit Earth. Also at the site was evidence of charred trees, an inland tsunami and melted amber.
The impact marked the end of the Cretaceous Period and was responsible for a mass extinction event for most of life on Earth.
