A high-stepping, feathered Velociraptor bares its teeth as it rushes toward the reader from the cover of this book in the “Smithsonian Prehistoric Zone” series. As with all twelve books in the series, the opening page highlights the evolution of dinosaurs and is complete with an illustrated graph that covers the Triassic, Jurassic, and Cretaceous Periods. The first text page includes an enticing illustration and attention-grabbing short sentences that draw readers into the tale.
