A do-it-yourself manual of dinosaur collecting is what this book amounts to. Mark Speer and Tommy Coleman, two aspiring young geologists, go off on a field trip and discover dinosaur bones. An excavation project is organized under the leadership of a paleontology professor, but is balked by an enterprising gentleman who has just purchased the dinosaur site with the intention of beginning construction of a resort in the next three days. The whole Colorado Community joins the project, and the real estate developer, recognizing the potential publicity, decides to hold off construction, and to include in his plans a natural history museum. The story is barely developed and provides only a loose, poorly dramatized background for the information about dinosaurs and palaeontology, of which there is a fair amount.
