Apatosaurus louisae bones in Carnegie Quarry, Dinosaur National Monument, Utah, USA

Apatosaurus louisae leg bones in the Dinosaur Quarry at Dinosaur National Monument, Utah, USA. Later discoveries of so-called "Brontosaurus" bones are a misnomer, as all bones of this sauropod (long necked dinosaur) should now be labeled Apatosaurus. The only Apatosaurus skull in the world was found in the Carnegie Quarry because the sand-sized sediment preserves bone in great detail without compressing its fragile bones. In Dinosaur National Monument, the popular Dinosaur Quarry displays a spectacular logjam of Jurassic dinosaur bones. The park is on the southeast flank of the Uinta Mountains straddling Colorado and Utah at the confluence of the Green and Yampa Rivers. Although most of the monument is in Moffat County, Colorado, the Dinosaur Quarry is in Utah near the town of Jensen, USA.
