The discovery of dinosaurs by retired housewife turned scientist Joan Wiffen has cast a new light on the behaviour of dinosaurs during the late cretaceous period, and the puzzle of why dinosaurs, in general, became extinct. This programme tells the remarkable story of Joan Wiffen, who at age 68, went fossil hunting and found New Zealand's first dinosaur bones.
