Episode 1

Liz Bonnin joins an international team of palaeontologists in the remote badlands of Wyoming as they investigate a mysterious dinosaur graveyard.

Packed with over a dozen skeletons, including predators such as the fearsome Allosaurus and iconic giants like Diplodocus, as well as fossilised plants and footprints, the site is a treasure trove that is helping to change the way we think about the Jurassic – the golden age of dinosaurs. The astonishing evidence also helps the team to answer why so many dinosaurs came here and what killed them in such great numbers 150 million years ago.
