Episode Overview

Deep in North Dakota's Badlands, a group of researchers believes they've uncovered fossilized remains from creatures that perished during the cataclysmic asteroid impact 66 million years ago. Their findings suggest a devastating event, featuring an array of unique fossils, such as a pterosaur embryo encased in its shell and a remarkably preserved piece of triceratops skin, all mingled with tiny glass and clay spheres thought to be remnants from the asteroid strike. Sir David Attenborough leads the investigation, seeking vital insights into the final moments of the dinosaurs on Earth.
