The app that really does let you walk with dinosaurs: Prehistoric monsters can roam your home using augmented reality
They have been seen stomping down the street, crashing round in kitchens and sneaking around at school.
Thanks to a new app, dinosaur fans have been able to pose with the prehistoric creatures using augmented reality technology.
The 'Walking with Dinosaurs Photo Adventure' app uses the camera function of a mobile or tablet device to allow users to pose with dinosaurs in modern surroundings.
The app is free to download from the iTunes and Google Play app stores. Users can pretend to be chased by dinosaurs by placing and posing virtual dinosaurs in the camera view, with options to adjust lighting and add colour to the prehistoric creatures

Users can also watch dinosaurs fight it out in front of them as the Pachyrhinosaurus and Gorgosaurus vie for territory.
The app was made by BBC Worldwide, Twentieth Century Fox and Evergreen Studios to complement a forthcoming 3D film.
Walking with Dinosaurs will arrive in cinemas this Christmas, from December 20. It sees Patchi, an underdog dinosaur (a Pachyrhinosaurus) and his tough brother Scowler, triumph against all odds to become heroes after battling the villain of the film - a Gorgosaurus.
