Doraemon: Nobita's Dinosaur

Doraemon and his friends travel to ancient Japan where they meet Kukuru. When Kukuru tells them that his tribe has been enslaved by Gigazombie, Doraemon decides to help him.

When Suneo does not show Nobita the fossil of a dinosaur claw, he takes up a challenge to find a dinosaur. He digs up a hillside and finds an egg, which later hatches and becomes a dinosaur.

Nobita tries to prove to Doraemon and his friends that dinosaurs are still alive, and, after finding an underground cave, discovers a hollow earth civilization of knights and saurian steeds that Suneo must be rescued from.

Nobita wishes the world into a magic-reliant one with Doraemon's Moshimo-Box, and, along with his friends, must stop an asteroid from hitting the planet with help from a sorcerer-in-training.

Nobita accidentally finds a fossil dinosaur egg mixed with rocks in the dinosaur fossil exhibition site that he had visited before. He returns it to its original state with the 'time blanket'.
