A visit to the Natural History Museum turns into an adventure for Katie when she steps back in time to the world of the dinosaurs! Katie helps a baby dinosaur find his family, rides on the back of a Brontosaurus, and has a picnic with a Triceratops! But just what will she feed a very hungry and fearsome Tyrannosaurus Rex? James has been delighting children with his Katie stories for over 25 years. This new-look book celebrates quarter of a century of Katie adventures.
