Giant sauropod dinosaur skeletons from Patagonia; dinosaurs with feathers from China; a tiny dinosaur tail suspended in Burmese amber. Remarkable new fossil finds may be the lifeblood of paleontology, but it is advances in technologies and methods that have fostered the revolution in the field. Though they haven't roamed the planet for millions of years, dinosaurs are still very much a part of our world. Michael J. Benton takes us behind the scenes on expeditions and in museum laboratories to trace the transformation of dinosaur study from its roots in natural history to the scientific discipline it is today. New technologies have revealed secrets locked in the bones in a way nobody predicted- we can now work out the color of dinosaurs, their growth, feeding and locomotion, how they grew from egg to adult, how they sensed the world, and even whether we will ever be able to bring them back to life.
