Why do people still care about dinosaurs? The ‘Introduction’ explains how dinosaurs were officially ‘born’ in 1842 with the work of Richard Owen, and gained fame in the reopening of the Great Exhibition in 1854. Dinosaurs are popular because they pull on the creative imagination and link real life to myth and legend—Protoceratops fossils look startlingly like the mythical griffin. Nobody has ever seen a living dinosaur, but scientific analysis has provided insights into how these animals lived on Earth between ~230 and ~66 million years ago (Ma). Their very existence and extraordinary body forms incite curiosity, inspiring many children to pursue careers in all walks of scientific life.
