The Land Before Time X: The Great Longneck Migration is the tenth film in the Land Before Time series.
In this film, Littlefoot and other longnecks have strange dreams. One day, all the longnecks instinctively know that they should go somewhere. Littlefoot and his grandmother and grandfather go to the journey like all other longnecks, leaving the other races behind. Cera, Petrie, Spike, and Ducky (Littlefoot's friends) are missing Littlefoot, so they go on a voyage to find him. After a few days of voyage they became friends with one longneck and continue their quest to find Littlefoot with him. Meanwhile Littlefoot and most of the longnecks come to a meteoric crater, which they believe is the culmination of their journey. Here, Littlefoot meets his father, Bron, for the first time in his life!
However, the sire is not alone. Since parting from his (now deceased) mate, he has become guardian to another Apatosaur, Shorty. Littlefoot and Shorty are not friends, because Littlefoot's dad is spending more time with Littlefoot and less with him. One dawn Shorty tries to leave crater and go far away. Littlefoot stops him and convinces him to rejoin the migration. At this point, Littlefoot's friends come upon him.
They are attacked by Sharpteeth, but soon every herbivore is there to defend them. A meteorite falls into the Crater, causing the longnecks to break up and go home. Littlefoot and his father separate, knowing one another's true places.
