In recent decades, many countries, including former colonies of European empires, have requested the return of cultural and historical artefacts taken away years ago, many of which are housed in museums reluctant to surrender their collections. Mongolia has made some headway in claiming back its cultural artefacts. Earlier this year, the United States returned dinosaur fossils taken out of Mongolia, including the skull of an alioramus, a smaller version of a tyrannosaurus rex that lived 70 million years ago.
