All 13 instalments of the prehistoric animated children's adventures. In 'The Land Before Time' (1988), young dinosaur Littlefoot (voice of Gabriel Damon) is orphaned and so he sets off with a gang of fellow baby dinosaurs in search of a legendary green valley that offers safety from the plague that is sweeping the world. In 'The Land Before Time 2 - The Great Valley to Heaven' (1994), the young dinosaurs are coaxed into the forbidden 'Mysterious Beyond' by the mischievous Cera (Candace Hutson), and they realise that everything in their world is not as idyllic as they had thought.

In 'The Land Before Time 4 - Journey Through the Mists' (1996) Longnecks brings news of change from beyond the Great Valley: of mists and strange creatures that inhabit the marshes and trees.

In 'The Land Before Time 5 - The Mysterious Island' (1997) Littlefoot, Cera, Spike, Ducky and Petrie ignore the advice of their elders and set off to discover an island of beauty and mystery that lies beyond the Great Valley.

When baby dinosaurs Threehorns, Dinah (Sandy Fox) and Dana (Nancy Cartwright) run away to investigate, it is up to Littlefoot, Cera, Spike, Ducky and Petrie to bring them back. In 'The Land Before Time 7 - The Stone of Cold Fire' (2001) Littlefoot sees an amazing sight, a 'stone of cold fire' that falls from the sky and lands in the mountains. But when he tells his friends about it, none of them will believe him. In 'The Land Before Time 8 - The Big Freeze' (2001) the entire group of dinosaurs are trapped in the valley by a snowstorm. A group of them decide that since they need to eat more than the others they will leave the valley. One of the dinosaurs who leaves is Spike and so Littlefoot and his other friends have several adventures trying to get Spike and his family to return to the valley. In 'The Land Before Time 9 - Journey to the Big Water' (2002), when heavy rain creates a mysterious 'new water', Littlefoot (Thomas Dekker) sets off to explore the Great Valley. He quickly becomes friends with Mo (Paulsen), a prank-playing dolphin-like creature who can't find his way back to the Big Water. Littlefoot and his prehistoric pals come to the rescue, evade a scary sharptooth - and prove the value of courage, friendship and diversity. In 'The Land Before Time 10 - The Great Longneck Migration' (2003) Littlefoot (Alec Medlock) dreams that he has found a land filled with brontosauruses like him. When he tells his grandparents (Kenneth Mars and Miriam Flynn) about the dream, they take it as a sign that they should set out and look for the land Littlefoot is describing. In 'The Land Before Time 11 - Invasion of the Tinysauruses' (2005), when Littlefoot (Aaron Spann) gets into trouble after telling a lie, the Tinysauruses invade the Great Valley so they can teach him a lesson. In 'The Land Before Time 12 - The Great Day of the Flyers' (2006), Petrie is having a difficult time preparing for 'The Day of The Flyers' - an important calendar mark for all of the flying residents of the Great Valley. On this special day, all young flyers must participate in a flying exhibition to prove that they are ready to fly with the adults. At the same time, a strange newcomer to the Great Valley has Littlefoot and his friends trying to help figure out just exactly what he is. His name's Guido (Paulsen) and he's the strangest looking creature anyone in the Great Valley has ever seen, as he's covered with multicolored 'fuzzies' (feathers). Finally, in 'The Land Before Time 13 - The Wisdom of Friends (2007), Littlefoot (Cody Arens), Cera (Anndi McAfee), Spike, Petrie and Ducky (Aria Noelle Curzon) meet up with lovable yellow-bellied Beipiaosauruses, Loofah (Cuba Gooding Jr.) and Doofah (Sandra Oh), who've managed to lose their way while travelling to the distant Berry Valley. The pair are too awkward to find their way back easily, so Littlefoot and the others help them on their journey, learning some important lessons about life along the way.
