Scientists from Manchester University and the Natural History Museum are excavating a square-mile of desert in cowboy country in Wyoming for 'Mission Jurassic' - the biggest British dinosaur hunt in decades.
They've already discovered more than a dozen animals but think there may be over 100 dinosaurs there – including species new to science.
The BBC was given special access as the dig gets underway and we should tell you we've disguised the location in our report to protect the area from fossil thieves.
