Welbeck's Ultimate Dinosaur Encyclopedia covers prehistoric life from the very first vertebrates to the world's mightiest dinosaurs. This app transforms the book into a unique digital experience:

- Activate amazing videos of dinosaurs in motion, which appear to play on the pages of the book.

- Trigger detailed 3D models of selected dinosaurs, including Triceratops, Allosaurus, Stegosaurus and more. View them from every angle with your device, and tap the hotspots on each dino to bring up fact boxes.

How it works:

Once you press the play button on the app’s opening screen, simply look at the interactive pages of your Ultimate Dinosaur Encyclopedia book through the app. Look out for pages with interactive boxes with the camera icon, marked 'SCAN THIS PAGE'.

If you don’t already have the book, tap the play button on the app's opening screen and wait for 20 seconds to get a link to a retail page outside the app where the book can be purchased.

This free app is available to anyone with compatible Android devices running Android 7.0 and above and supporting Google's ARCore v1.7 or higher.
