This 26 March 2019 video about the USA says about itself:
The Natural History Museum [in London, England] has joined an international partnership, called Mission Jurassic, to excavate a new Jurassic site. The project is named after an area known as the ‘Jurassic Mile’ in Wyoming, which has many Jurassic dinosaur and fish fossils, trackways and fossilised plants.
NHM is working with The Children’s Museum of Indianapolis and the Naturalis Biodiversity Center in Leiden, Netherlands on the US dinosaur dig, the UK museum’s first major overseas dig since the 1980s.
Translated from Leidsch Dagblad daily in the Netherlands, 25 March 2019:
Naturalis Biodiversity Center in Leiden returns to Wyoming. Together with two other natural history museums, the Natural History Museum in London and the Children’s Museum in Indianapolis, Naturalis is going to dig up in the United States at least two long-necked dinosaurs. The Leiden museum previously found the well-known T. rex “Trix” in Montana and five Triceratops in Wyoming.
Countless bones, fossils and footprints of the largest dinosaurs that have ever lived come together on the Wyoming site. “We hope to learn a lot about biodiversity in the Jurassic at this place”, says paleontologist and team leader Anne Schulp. “This was the period of the well-known long-necked dinosaurs such as Brachiosaurus and Diplodocus. We go back some 150 million years in this excavation. That is far before the Tyrannosaurus rex that now shows off in the museum.”
… The location has been known for some time. The Children’s Museum started the first trial excavations two years ago. That has since produced the first bones of two long-necked dinosaurs.
Naturalis, which will reopen at the end of the summer, has a “dinosaur hall” in the new building dedicated to the Jurassic era (201-145 million years ago). The museum already has a skeleton of a long-necked dinosaur from that period in its collection for that hall. That is a Camarasaurus, but, says Schulp, “it is a small one at 17 meters.”
