Doraemon: Nobita's New Dinosaur (2020) on Netflix

Plot summary

Nobita vows to his friends that he will find a dinosaur, and after an excavation experience he trips over a rock that proves to hold a fossil egg. Doraemon restores it with a time blanket, and two Sinosauropteryx hatch, a species missing from the Complete Encyclopedia of Space. Nobita names the twins Kyu and Myu and takes advice from Dr. Dinosaur on raising them. The two grow fast and develop differently: Myu learns to fly, while the smaller Kyu does not. Nobita's room becomes cramped, so the pair move into a Breeding Diorama Set. When Kyu and Myu cause a commotion and the townspeople catch sight of them, the friends decide the animals belong in their own era.
