The Ultimate Dinopedia is organized by the periods that are well known to young enthusiasts: Triassic, Jurassic, and Cretaceous. It includes almost every dinosaur ever discovered, and highlights 125 species that scientists know sufficiently to describe in rich detail. Special features include How We Know What They Looked Like, Baby Dinosaurs, Great Dinosaur Goofs, and much more. Every featured dino gets a fact box that delivers important information at a glance—Scientific Name, Discoverer, Place and Date of Discovery, Length, Habitat, Diet, Fossils, Fun Facts, and Range Map.
