This video is called Dinosaur Tracks in Southern Utah.
From Deseret News in the USA:
An excavation team has unearthed a major dinosaur fossil discovery in southeastern Utah, the Bureau of Land Management announced Monday.
In three weeks of excavating the preserved river channel near Hanksville, a team from the Burpee Museum of Natural History in Rockford, Ill., found four long-necked sauropods, two carnivorous dinosaurs and a possible herbivorous Stegosaurus. …
The sandstone quarry has kept the fossils “exceptionally well preserved,” he said. Some fossils have had to be put back together, but many were preserved as complete pieces.
In Hanksville, local officials knew the site contained bones when the Burpee team began excavating last year, Foss said. “When they got out there, it was bigger than they anticipated.”
No new species have been discovered, and Foss said he doesn’t expect to find any at the Hanksville site.
