Doraemon: Nobita and the Knights on Dinosaurs^[3] (ドラえもん のび太と竜の騎士, Doraemon Nobita to Ryū no Kishi) is the eighth feature-length Doraemon film which premiered on March 14, 1987 in Japan, based on the eighth volume of the same name of the Doraemon Long Stories series. It was the highest-grossing animated film of the year 1987.

Nobita argues that dinosaur still exist, Suneo then disproves him while Gian, Shizuka takes his side. He asks Doraemon for help but later gets convinced by Doraemon's gadget that dinosaurs are extinct when he asked whether there are dinosaurs alive "on" earth. Meanwhile, he has to find a place to hide his test papers from his Mom. While playing with Suneo's remote control airplane, Gian loses control of it and it falls into a river. After Gian fled, Suneo saw a huge dinosaur 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 using the Anywhere Hole. At night, Suneo again spots the same dinosaur in his yard but thinks he is mentally ill.

The next day, Nobita takes everyone to the tunnel. Suneo comes out of an exit and spots a herd of dinosaur but no one believes him. The day after that they again go underground and play while Suneo comes with camera and manages to record his plane that had crashed into the river earlier. Frightened, he runs in a cave, gets lost and gets caught by a knight on dinosaur. The others have to hurry home as Gian's and Nobita's moms are furious after realizing they had made up an excuse to leave their house, leaving the Anywhere Hole in the empty lot.

The day later, the Anywhere Hole is virtually destroyed by a truck, preventing them from going underground again. Doraemon goes to everyone to apologize and finds that Suneo still hadn't returned home. Nobita and Doraemon watch Suneo's recordings from his camera that they recovered and discover that his plane is still flying in there. Everyone at night go to the river and find another entrance to an underworld where they are caught by native Kappas. They are saved by a knight, Banhou who tells them that Suneo is in their capital Enriru. They go to the capital and find Suneo. Banhou tells them that their memories will be erased once they are allowed to leave.

While Banhou has to go for training, he asks Roo, his sister to show them the underworld but warns them to not go to a forbidden place. They go to museum to find that underworld human have evolved from dinosaurs and that something or someone is reason for extinction of dinosaurs. They also see a perfectly rectangular area in the underworld. Roo, along with the majority of the underworld's inhabitants are unaware of the existence of the true sky, Sun and stars.

While riding a Dinosaur, Nobita is accidentally taken to the forbidden building, where he finds a large ship and overhears plans to get surface of Earth back from mammals. Nobita comes back to warn everyone and they run away. While attempting to flee from Banhou's ship, they get caught by Kappas where they are nearly killed, but Banhou's ship comes and saves them.

The ship turns out to be a time machine which takes them to the Cretaceous era. Revealing that the underworld people thought extraterrestrials were responsible for extinction of dinosaurs. Nobita and everyone again flee from ship and make a camp near the ship. Shizuka spots a comet approaching since they came there. Knights attack their base while the comet which they realize is the asteroid which killed off most of the dinosaurs hits earth causing a huge tsunami.

The knights rush to the ship which is able to hide underground, while Doraemon blasts a tunnel underground to hide from Tsunami. They realize that they made the same large rectangular place which is the size of the island of Hokkaido as seen in the map of the underworld. After the water is no longer above them, all of them come out and go back to the surface. Doraemon explains that the asteroid caused the death of the majority of plants and plankton. Animals which are dependent on plants and other animals suffered while mammals hibernated to remain alive. The underworld people then think it was God's that Dinosaurs became extinct. Doraemon then helps them to make the underground world they reside in and to take all remaining Dinosaurs there.

The film ends with the main characters being treated as heroes and sent to the surface without erasing their memories and their stuff stuck underground being sent back to them.
