Dinosaur Bones

In a time when dinosaurs rule the Earth, the smallest dinosaur of the herd, a playful Pachyrhinosaurus named Patchi, embarks on the biggest adventure of his life. As he tries to find his place in a spectacular world filled with fun-loving friends and a few dangerous foes, Patchi will discover the courage he needs to become the leader of the herd and a hero for the ages.

As the Great Day of the Flyers nears, the Great Valley's flying youngsters are eager to participate in the annual exhibition to show off their skills. Everyone, that is, except free-spirited pterodactyl Petrie, whose individualism causes problems when it comes to staying in formation. Enter his dinosaur pals Littlefoot, Cera, Spike and Ducky, who encourage Petrie to embrace his uniqueness.

Littlefoot's grandfather narrates the story about the Lone Dinosaur that killed a Sharptooth. A giant monolith formed after the fight and if it's destroyed, bad luck will loom over the valley.

When the dinosaur families get trapped in a valley by an ice storm, one family of "spike tail" dinosaurs volunteers to leave since they consume more food than the others. Meanwhile, the young dinos and a new adult dinosaur named Mr. Thicknose, head out to bring back their friend Spike, who has left his friends to be with members of his own species.

Littlefoot learns a series of important lessons following an incident that nearly costs his grandmother her life. Soon afterwards, three dinosaurs arrive claiming they have lost their way.
