Geologists from Brigham Young University in Utah have recently discovered literally thousands of bones in the city of Moab. A total of 4,200 bones were collected, accounting for 8 species of dinosaurs; however, almost all of the bones were fractured. Subsequent tests proved that the bones were pulverized shortly after becoming present, as a "greenstick" fracture in a bone indicates that its presence is fresh. It has been hypothesized that herbivorous sauropods and iguanodontids stomped over the carcasses of smaller dinosaurs while trying to reach a shrinking lake; this also indicates that the extinction of dinosaurs in this particular area was due to a massive drought. It has been assumed that the bones were crushed during the Early Cretaceous Period of prehistoric history.
