Within are 28 descriptions of dinosaurs over 30 pages containing facts and opinions about prehistoric reptiles (see sample pages in the pictures). However, it is not just a book. A free application running on smartphones with Android and IOS turns the book into an adventure. All you need to do is download the application onto a smartphone or tablet and use it to look at the book’s pages. A three-dimensional, animated dinosaur will emerge! The application works with 10 dinosaurs marked with an icon (Plesiosaurus, Megalodon, Stegosaurus, Triceratops, Velociraptor, T-Rex, Ankylosaurus, Pteranodon, Carnotaurus and Quetzalcoatlus.) The application is extremely easy to use, just run it and it will work without any additional set-up requirements. It automatically triggers the camera on the device, the view displayed on the screen in the usual way. However, if you then look at a page of the book featuring one of the dinosaurs above an animated version, similar to a hologram, will appear in 3D. This works both with the paper and electronic version of the book.
