A delightful tale of two close friends and their eventful day at the museum with the dinosaurs, with lots of facts about how dinosaurs lived and why they all disappeared

Join Britain's much-admired monarch on one of her rare days off, as she and her loveable pet corgi Mr. Brown enjoy an action packed adventure at the Natural History Museum. On a gray, gloomy, and unbearably miserable day, the two friends go in search of dinosaurs. Armed with snacks, they encounter immense skeletons, huge teeth, and a thigh bone as big as the Queen. There are aliens from outer space and some smelly dinosaur dung too! After so much exploring it is no surprise when they both fall asleep—which is when the real excitement begins. Find out what really happened to the dinosaurs all those years ago, what the Queen is doing on top of a Megalosaurus, and who wins a famous victory.
