An orphaned brontosaurus named Littlefoot sets off in search of the legendary Great Valley. A land of lush vegetation where the dinosaurs can thrive and live in peace. Along the way he meets four other young dinosaurs, each one a different species, and they encounter several obstacles as they learn to work together in order to survive.

After an incident which nearly cost Littlefoot’s grandmother her life, Littlefoot learns a series of lessons which his species call “Wisdoms”. Meanwhile, a trio of dim-witted Beipiaosauruses named Loofah, Doofah and Foobie arrive in the Great Valley and behave in a strange manner towards Littlefoot and the gang. Littlefoot is determined that they learn the “Wisdoms” and the journey to the one place the trio have dreamed of, Berry Valley, begins.

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.

A bedtime story leads Littlefoot and his grandparents on a journey to a new land, where Littlefoot discovers someone who vanished before he was born: his father! Now Littlefoot must decide between two worlds. Will he leave to be with his friends in the Great Valley, or stay behind and start a new life with his father?

Littlefoot and his pals set off in search of a “stone of cold fire” that fell from the night sky. Since he’s the only one who has seen it though, nobody really believes him. Littlefoot’s uncle Pterano offers support only because he thinks the stone has secret powers and wants it for himself but conceals this from the rest. The young dinos must figure out the truth, before Pterano gets the power.

Legends claim that Saurus Rock keeps bad luck out of the Great Valley. Is it really true? Could the mysterious Longneck named Doe be the famous Lone Dinosaur, who can defeat a Sharptooth with his lasso-like tail? To find out, Littlefoot and company must cross theiGreat Valley and face a dangerous Sharptooth themselves!

This fourth sequel in the series finds “leaf gobblers” eating all the vegetation in Great Valley, driving Littlefoot, the young brontosaurus, and the other dinosaur inhabitants out. Arguments break out among the adults during migration, and Littlefoot and his friends decide to take matters in their own hands by crossing the “big water” to an unknown island. There they meet an old friend from The Land Before Time II–Chomper, the T-rex, who has to protect the gang from his own, carnivorous parents. Plenty of drama in this one, and as the series has been wont to do from the beginning, it shows adults as sometimes being less than perfect.

Beloved dinosaurs Littlefoot, Cera, Spike, Petrie and Ducky return in this story about the wonders of discovery that features new songs, including Donny Osmond’s “No One Has to Be Alone.”

Littlefoot and the gang meet a shy newcomer, Ali, but the pleasantries stop there. There’s a dire environmental theme to this third sequel in the series, in which the world’s weather changes beyond the Great Valley, and what had been dry land is now a “land of mists.” The shift brings new creatures who push out older inhabitants, and Littlefoot sees these radical changes for himself when he has to venture into the area to find a medicinal flower for his sick grandfather. While the animation is slow and contained the way direct-to-video cartoon releases often are, the story is sound and the now-familiar characters are memorable.

Littlefoot and his friends are constantly being bullied and browbeaten by three teenage dinosaurs: Hyp, a Hypsilophodon; Nod, a Nodosaurus; and Mutt, a Muttaburrasaurus. However, when a shower of meteorites (flying rocks) impacts near the Great Valley and causes a rock slide in the Mysterious Beyond, which blocks the water supply of the Great Valley, Hyp, Nod, and Mutt are no longer the biggest worry of Littlefoot and his friends. The increasing lack of water causes conflicts between the inhabitants of the Great Valley, who have lived in relative peace and harmony until this event.
