Amazon.com description: Product Description: The always-fascinating dinosaur gets a new twist in this kit book that lets young paleontologists bring these ancient creatures to life. Each page has clues that help readers discover the correct body parts to use to create such enduring favorites as stegosaurus, T-Rex, triceratops, brachiosaurus, and four others. The kit includes profiles of each of the dinosaurs along with 40 snap-on tails, scales, claws, and jaws. Each body part is illustrated and its function explained, as in, for example, "Sharp horns are for self-defense." Once a dino is constructed, kids can then swap out parts to create their own mutant versions.
