Doraemon

Suneo shows everyone but Nobita a fossil of dinosaur claw. Angry, Nobita claims he will be able to find a living dinosaur. As Doraemon refuses to help him, he digs on a hillside, but instead earns punishment from landlord nearby who forces him to unearth a hole in the ground. He finds an egg-shaped stone underneath and quickly uses a time wrap to returns it to its former form and after warming it, the egg hatches to reveal a Futabasaurus, who is subsequently named Pisuke by Nobita. Instead of immediately showing the others, Nobita waits it grow while making a deal with others. As Pisuke grows too large and is in danger of being found, Doraemon and Nobita transport him to 100 million years ago in the Late Cretaceous period. They are attacked by a mysterious assailant who previously tried to make a deal with Nobita to sell Pisuke, though they manage to escape. Left with no proof, Nobita instead shows them Pisuke through television monitor, but realizes that he and Doraemon had unknowingly transported Pisuke to the North American shore after the time machine was attacked by the assailant. They and the others decide to go there, but the time machine is overloaded and crashes off. The group land on the North American shore and found Pisuke, but the time machine is broken and must be taken back to Nobita's desk in faraway Japan if they want to go back to the present time. As they travel across the land connecting North America and Asia, they meet with various Dinosaur species who either help or hinder their progress, such as Ornithomimosauria, Apatosaurus, and Tyrannosaurus. At a cliff, they are attacked by a pack of Pteranodon who break their bamboocopters. They are saved by the mysterious assailants, who reveal they are dinosaur hunters working for a fossil collector named Dormanstan from the 24th century. They offer to return them back home in exchange for selling Pisuke. Refusing the deal, the group set a lure for the hunters while they escape across a river. However
