From the book description:
Create moving models of five different dinosaur species — from ichthyosaurus, the fish lizard, to Tyrannosaurus rex, the tyrant king, along with the armor-plated stegosaurus, the flying pterodactylus, and the bone-haded pachycephalosaurus. Kids ages 10 and up can follow simple directions that explain how to build the crank-powered replicas. The book is also loaded with facts about all sorts of dinosaurs and includes a background play scene and a convenient pocket for storing loose pieces
Though it's sold in book format, it really a kit, or five kits to be exact. Dinosaurs and automata -- two things that kids love!
