If you travel back 156 million years to the western USA, you'll find a far different land from today. One that is ruled by the dinosaurs, the largest among them being the long-necked sauropods.

Witness one year in the life of a young sauropod, Blue-Eye, and her many siblings as they attempt to survive the challenges of the Morrison Formation, all while slowly learning the secrets of who they are.
