British scientists are about to undertake one of their biggest dinosaur hunts in decades.
They are joining the US and Dutch institutions in exploring what is expected to be a treasure trove of fossils in the "Badlands" of Wyoming.
The US state has yielded some of the most famous specimens ever found, and the international group will excavate one square mile (260ha) of the ground.
"It's an incredible site, mind-blowing," said Prof Phil Manning.
"In the UK, we rarely see anything like this - whole dinosaurs coming out of the ground. But that's what we've got here," the University of Manchester paleontologist told BBC News.
"And the funding we have in place permits us to open up football pitch-sized areas at a time if need be."The partners on the project are The Children's Museum of Indianapolis; the Naturalis Biodiversity Center in Leiden, Netherlands; and London's Natural History Museum.
Prof Manning and Manchester colleague Dr. Victoria Egerton are Extraordinary Scientists in Residence at the Children's Museum and will act as lead researchers, but such is the scale of this endeavor that a team of more than 100 experts will be required.
The project has been dubbed "Mission Jurassic" - a reference to the major geological period in which the rocks to be studied was laid down.
