Wyoming - US

The discovery of numerous fragments of dinosaur bones on private lands southwest of Cody is significant because the fossils occur in the Thermopolis Shale, traditionally thought to have been deposited in a dominantly marine environment. Prior to Wyoming this, only traces of marine reptiles and invertebrate fossils had been found in this 100 million-year-old formation.

The new fossils, however, are definitely from dinosaurs that lived on land. Dr. Michael Cassiliano, a University of Wyoming paleontologist, visited the discovery and verified the fact that they were indeed dinosaur bones. This is the second recent find in the Bighorn Basin area that provides evidence of dinosaurs living in what was thought to be a dominantly marine environment.
