Wall of Bones

This picture of the what they call the "Wall of Bones" was taken inside the Quarry Exhibit Hall at the Dinosaur National Monument off Route 149 about seven (7) miles North of Jensen, Utah.  As was reported in the The Vernal Express on August 20, 1909 and I quote verbatim "On August 17, 1909, Earl Douglass found eight (8) tailbones at the top of a nearby hill" which was later to be identified as a river bed known as the Morrison Formation from the Jurassic time period.  The Dinosaurs and other ancient animals were washed into the area and buried presumably during flooding events.  One of the Dinosaurs discovered was the Allosaurus which means different lizard. It was a large bipedal predator which measured in  length of 28-39 feet.  These bones shown in the photo are just how Earl found them over 100 years ago, amazing!
