"Doraemon and the small dinosaur" is an adventure that takes you the age when dinosaurs domained the Earth. The film, launched in Japan in 2006, is a remake if the first Doraemon film, released in Japan in 1980. The latest animation techniques, both the traditional 2D and that computer-generated, are present in this new production featuring the usual characters with an updated look. ‘I wish I could find a dinosaur fósil!’, dreamer Nobita thinks. The rest of the group of friends does not take it seriously , but Nobita tries his best to shut his friends up. The most surprising thing is that in his first excavation he finds a new egg that could well be a pre-historic animal’s. Helped by Doraemon, Nobita manages that a futabasauro be successfully born, a sort of Japanese indigenous specie from una especie autóctona de Japón, al que bautizan como Pisuke. El pequeño dinosaurio crece a toda velocidad, lo que dificulta su existencia de incógnito. De la noche a la mañana, Pisuke atrae la atención del barrio y de los medios de comunicación, de modo que Doraemon y Nobita deciden que lo más sensato es devolverlo a su hábitat prehistórico mediante la siempre útil máquina del tiempo.
