A repatriation ceremony was held in New York on Tuesday to transfer dinosaur fossils to the custody of Mongolia's government.
The US handed back the remains of six species of dinosaurs smuggled out of the country and impounded by federal agents in New York and Utah.
The largest item was the skull of an Alioramus, an exceptionally rare dinosaur believed to have roamed the Gobi Desert 66 to 70 million years ago.
