(Moab Utah)- Paleontologists are excavating the first dinosaur ever discovered in Utah, 155 years after a geologist discovered the skeleton of the mammoth plant-eater during an Army engineering survey of the West. When geologist J.S. Newberry found the bones of the Dystrophaeus on the confluence of the Colorado and Green rivers in 1859, he could only dig out a few and told others later that there were more to be removed. But the site’s location was lost for decades, and the work hasn’t continued until now. The excavation started last week and included a special ceremony Thursday marking the discovery more than a century and a half earlier. John Foster, Executive Director of the Museum of Moab says, soon after Newberry’s discovery, the Civil War broke out and his report languished for about 17 years. The report was buried when it was finally published, Foster said, and eventually the site’s location above a canyon south of Moab was lost. Researchers rediscovered it in the late 1980s after a 12-year search. Since then, Foster said it’s taken years to come up with a plan and funding to pay for the excavation. The project is now being paid for by a grant of about $9,000 from the nonprofit Canyonlands Natural History Association, Foster said.
