Last Utah Sauropod Fossil Tract Unearthed By Smithsonian
Smithsonian paleontologist Dr. Charles W. Gilmore announced bones of a gigantic sauropod found in western Utah may mark the last habitat where these giants faced extinction. The 60 million year old remains suggest a late Cretaceous end as mammals emerged in North America, with 70 million year old mammal beds above the dinosaur fossils. Ribs, a seven foot thigh bone, four feet of tail bone and other fragments were recovered, in beds originally found by the US Geological Survey.
