The Dinosaur Hunters

One man who kept asking questions was Gideon Mantell, the amateur paleontologist who, in the early 19th century, fought to get the British scientific establishment to accept Britain had been inhabited by dinosaurs. As this dramatised documentary shows, Mantell had an uphill battle in a time when the biblical account of creation was considered literal truth and authorities such as the Reverend William Buckland were determined that science remain "the handmaid of religion".

In 1922 American paleontologist Roy Chapman Andrews led an archeological expedition into Mongolia's Gobi Desert and uncovered one of the richest dinosaur graveyards in the world. Political conflicts forced him to leave before he had even scratched the surface of the treasure below. In 1997, two paleontologists from the American Museum of Natural History were finally allowed to return, retracing Chapman's steps and unearthing some groundbreaking finds of their own. With spectacular on-location filming, archival footage from Chapman's expedition and impressive computer animation, it's an amazing journey back in time to a lost world where ancient giants once roamed.
