Dallas Campbell delves in to the Horizon archive to discover how our ideas about dinosaurs have changed over the past 40 years. From realising that lumbering swamp dwellers were really agile warm blooded killers, astonishing new finds, controversial theories and breakthrough technology have enabled scientists to rethink how they lived and solve the mystery of their disappearance. And they can even reveal whether dinosaurs might still be with us today.

Drawing on 45 years of Horizon archive, Dr Kevin Fong presents a documentary showing how the intriguing possibility of life on Mars has fuelled man's quest to visit the Red Planet.
