Focusing on the deinonychus, this is one of a series which offers a detailed exploration of some of the best-known and most unusual dinosaurs, providing profiles of key species, their contemporaries, and the world they lived in. Each book, which is accompanied by a colour poster depicting the featured dinosaur, includes questions, answers, fact-boxes, maps, time-lines and anatomical diagrams. The book discusses how the deinonychus attacked and defended itself; how it raised its young; and its food, enemies, habitats, fossil-sites, and specialized characteristics. It also incorporates an interactive fictional novel element, bringing together the narrative tension of science fiction with the graphic immediacy of computer games.
