Dinosaur Apocalypse: The New Evidence
In North Dakota, scientists use new fossils to reconstruct what life might have been like just before an asteroid wiped out the dinosaurs. The site reveals remarkable evidence, including the unhatched egg of a pterosaur, a huge flying reptile.
PBS’ premier science series helps viewers of all ages explore the science behind the headlines. Along the way, NOVA programs demystify science and technology and highlight the people involved in scientific pursuits.
