Trivia:
1. This film marked one of the early instances where the Doraemon series extensively used computer-generated imagery (CGI) to bring dinosaurs and their world to life, which was quite innovative for its time.
2. The movie's story was inspired by classic adventure tales and dinosaur fascination popular in the late 1980s, blending science fiction with historical fantasy.
3. The voice actors recorded some of their lines underwater to capture authentic underwater acoustics for scenes set in the ocean cave, a unique and challenging production choice.
