Nobita's Dinosaur is the 21st chapter of Doraemon Volume 10. It's notable for being the first of the manga chapter to later be expanded into Doraemon Long Story and later adapted into the feature length Film "Doraemon: Nobita's Dinosaur".
Nobita makes a bet with Gian and Suneo to excavate and find a dinosaur to show to them. Will Nobita make a successful discovery? Or will he have to eat spaghetti through his nose?
- The entire chapter is used as the first part of "Doraemon: Nobita's Dinosaur", except with the addition of the Men in Black making a deal with Nobita and the chase to the prehistoric time.
