In 2012 a dinosaur skeleton became the subject of both a restraining order and a court case.
Mongolian palaeontologist, Dr Bolortsetseg Minjin helped stop the dinosaur falling into the hands of a private buyer after spotting a photo of the skeleton on TV in the United States.
The case became known as United States v One Tyrannosaurus Bataar Skeleton.
She told Gill Kearsley her extraordinary story.
