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 a quarter of a century. As part of the 25th birthday celebrations, we will be reissuing the whole series with an exciting new cover look.
