In 1993, a giant bone was discovered by an amateur fossil hunter in the badlands of central Argentina. The two paleontologists who were summoned to the site thought it was the thigh of a plant-eating dinosaur, but further examination showed it to be the shin of a previously unknown species of predatory dinosaur. Bigger Than T-Rex is an account of the excavation of the fossil and the subsequent reconstruction of a dinosaur thought to have been bigger, heavier, and fiercer than the reigning "king" of the meat-eaters, Tyrannosaurus rex. In clear, easy-to-follow language, dinosaur expert Don Lessem explains how the scientists drew conclusions about the size and habits of the new species, how they came to give it its name-Giganotosaurus-and how it compared to other dinosaurs. Illustrated with color photographs of the excavation and meticulously painted reconstructions of Giganotosaurus and other species, here is up-to-the-minute news about dinosaur discoveries for dinophiles of all ages.

Grade 4-6. Step aside T. rex?there's a newly discovered meat-chomping dino about to take your place. Lessem presents "hot from the excavation" facts about Gigantosaurus, a newly discovered Argentinian dinosaur whose skull was six inches longer than that of any known Tyrannosaurus rex. The author provides a thorough recap of the fossil's discovery by Professors Salgado and Coria, and includes plenty of full-color photos from the actual dig. Brightly colored sketches make Gigantosaurus come to life, and illustrations with accompanying text allow readers to compare this new carnivore with others of its ilk. There's plenty of material for reports, and most of the information here is too new to be found in other popular sources. This intriguing update to dinosaur collections will be both popular and useful, and it provides a much-needed view of paleontologists' work beyond the confines of the United States.?Cathryn A.
