The Dinosaur Society Dinosaur Encyclopedia is the first comprehensive and lavishly illustrated encyclopedia of the more than six hundred known species of dinosaurs, for readers of all ages, from ten on up. A new dinosaur is discovered every seven weeks, with nearly half of all dinosaurs known having been discovered in the past two decades. This is the first book to describe and illustrate all dinosaurs - including Eorapter, found in Argentina in 1993, and Utahraptor, discovered in the United States in 1992. This Utahraptor - "super slasher" - was a creature that hunted in packs, and may even have made Tyrannosaurus rex tremble. Each dinosaur is identified by genus, species, and family, and where and when it lived. Whenever possible, appearance, habitat, and behavior are described, and full-body and skeletal restorations are shown. Arranged in convenient alphabetical order, The Dinosaur Society Dinosaur Encyclopedia is a marvelous guide to the fascinating world of the dinosaur.
