Plot

When Nobita argues that prehistoric dinosaurs still exist on Earth, Suneo disproves him. He asks Doraemon for help but later gets convinced by Doraemon's gadget. While playing with Suneo's remote control airplane, Gian loses control of it, and it falls right into a river. After Gian flees, Suneo sees a huge Barosaurus lentus in the river. Fearful, he meets Doraemon and Nobita, but then runs away. Nobita and Doraemon go to the hill behind their school and Doraemon finds a tunnel. At night, Suneo again spots the same Barosaurus in his yard, but thinks he's mentally ill.

The next day, Nobita takes everyone to the tunnel. Suneo comes out of an exit and spots a Guaibasaurus candelarensis herd, but no one believes him.

Frightened, he runs into a cave, gets lost, and is caught by a knight on a Gallimimus bullatus. The others have to hurry home as Gian and Nobita's moms are furious. A day later, the Anywhere Hole is destroyed, preventing them from going underground again. At night, they go to the river and find another entrance to the underworld, where they get caught by kappas, who kill a Teratophoneus curriei. They are rescued by Banhou and go to a museum, only to find that the underworld humans have evolved from a Staurikosaurus pricei, and that something or someone is behind the extinction of that dinosaur.

While riding a herbivorous Concavenator corcovatus, Nobita is accidentally taken to the forbidden building. At the end of the film, the main characters are treated as heroes.
