National Geographic Dinosaurs

Paul Barrett's National Geographic Dinosaurs, illus. by Raul Mart!n, catalogues more than 50 of the ""terrible lizards."" A ""time bar"" running along the outside of the page indicates the period for each particular dinosaur; a ""Fact File"" provides the animal's genus, classification, weight and measurements; and a graph compares the dino's size to humans. Other sections focus on the Mesozoic through the Cretaceous period, paleontology and dinosaur behavior. Over 300 full-color photographs and 90 photorealistic illustrations add dimension. ( Oct.)
