Doraemon Movie : Nobita's Dinosaur (1980)

Suneo shows a fossil of a dinosaur claw to everyone except Nobita. Being 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 a 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 return it to its former form, and after warming it, the egg hatches to reveal a plesiosaur (Futabasaurus), who is subsequently named Piisuke by Nobita. Instead of immediately showing it to the others, Nobita waits for it to grow while making a deal with others. As Piisuke grows too large, Nobita and Doraemon hide him in the nearby lake 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 Piisuke, though they manage to escape. Left with no proof, Nobita instead shows them Piisuke through a television monitor, but realizes that he and Doraemon had unknowingly transported Piisuke 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 lands on the North American shore and finds Piisuke, 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. At night, while having dinner, Gian starts singing songs and a huge Tyrannosaurus appears from the forests. Doraemon uses his Momotaro Dango (Dumplings) to tame it and orders him to go back and the group decided to travel across the land connecting North America and Asia to return home. In their way, they meet with various dinosaur species who either help or hinder their progress, such as Ornithomimus and Apatosaurus. At a cliff, they are attacked by a pack of Pteranodon, who break their bamboocopters. Th
