When Little Blue gets lost from his herd, he is forced to use his wits.

You are about to visit a world very different from the one you know. You are about to see the planet Earth as it looked more than 120 million years ago. There were no people on Earth back then, there were plenty of dinosaurs: fast ones, slow ones, smart ones, small ones, and tall ones as high as houses! The Little Blue Brontosaurus belonged to one of the tallest dinosaur families: the brontosaurs. They loved to eat plants from the tops of trees. They liked to travel in herds for safety, just as elephants do today. But brontosaurs were not elephants. They belonged to another family of animals, one of the most fantastic groups to ever walk the Earth: The dinosaurs!
