The Big Fossil Discovery!

April Fool's Day is here. Gian gives Nobita a treasure map. Nobita believes it and digs around, but finds nothing. Nobita sees an old man digging something strange in the mountain. It turns out that the old man is digging for fossils. Nobita hears that the fossils are extremely valuable, so he works hard to dig them up, but is criticized by the old man. Nobita is dissatisfied. After returning home, he sees his mother making fish. Nobita has a sudden idea and uses "Time Cloth" to turn the fish into fossil and gives it to the old man. The old man believes it and wants to sell it. Doraemon goes to the garbage dump to collect garbage to make fossils, and meets the old man's daughter. She says, "Dad spends his life looking for fossils. It's great that you help him realize his wish." The two of them do not want to deceive the old man anymore and tell the truth. The old man faints and falls to the ground. Doraemon uses "Time Cloth" to restore fossils. As a result, there is a real fossil in the garbage dump, which is also restored. It is a trilobite fossil, but it is accidentally restored into a jumping trilobite.
