With 120 species described in detail, each illustrated with a full-colour, computer-generated image which brings it to life, this is a "photographic" identification guide to this fascinating group of creatures. As well as descriptive text for each species and its related family, there is an ID fact file which lists all the important information at a glance. A time line indicates the era in which the dinosaur lived and a scale guide also accompanies each one. Additional features such as eggs and habitat may also be illustrated.
