In their long journey from San Francisco to Lusk, Wyoming, in 1889, David (Siu-Long) Wong and his parents have encountered terrible prejudice because they are Chinese immigrants; but here they are given a job at John Bell Hatcher's paleontological excavation digging up dinosaur bones, including an eight-foot long Triceratops skull, and David becomes fascinated by dinosaurs and resolves to become a paleontologist. Includes historical note on J.B. Hatcher.
