Experience dinosaurs in 3D. With the help of the computer, ancient dinosaurs rise out of the book, move freely and roar loudly - so we can really see them. Living Dinosaurs tells about the fascinating dinosaurs whose size can only be compared to the giants we find in the oceans today. The dinosaurs lived in the water, on land and in the air about 230 to 60 million years ago. These giants were larger, and somewhat more fearsome, than any other animal now living.
