Once upon this same earth, beneath this same sun, long before mankind, before the ape and the elephant as well, before the wolf, the bison, the whale, before the mammoth and the mastodon, so on and so forth, was the time of the dinosaurs. The dinosaurs were of two kinds and different species: some had flat teeth and ate the leaves of trees, and some had sharp teeth for eating meat and they preyed upon the leaf-eaters. Then it happened when the leaves began to die. The mighty beasts who appeared to rule the earth were ruled, in truth, by the leaf. Desperate for food, some herds struck out toward the west searching for the Great Valley, a land still lush and green. It was a journey toward life. A march of many dangers. Sharpteeth stalked the herds waiting to seize any who strayed. The leaf-eaters would stop only to hatch their young. Yet, even hatching could be dangerous. One egg in question was left behind by its parents when its siblings were eaten by rodents. When it hatched, the little Thorn-Thumb (which is a simplified version of Iguanodon) looks up to see 3 Long-Necks (Apatosaurus) staring down at him. They decided to adopt the little guy, naming him Shard due to a piece of eggshell that was temporarily clinging to his head. The adoptive mother placed him on her back with his adoptive brother Littlefoot, letting him get used to this new family while the adoptive grandparents watch on with loving smiles. Eventually, Shard recognizes them by sight, scent and their love. He knew they would be together always. Of course, he doesn't know that that wouldn't be the case in the next few months (or years, depending on how you would view the timeskip in the movie).
