More than 65 million years ago, huge reptile like monsters roamed the earth. In Dinosaurs, David Lambert introduces the reader to the fascinating world of these prehistoric relics. Today their fossils remain an important link to the Mesozoic era and the types of creatures who lived during that time. Mr. Lambert traces the history of the dinosaur, from its first appearance on earth more than 200 million years ago to its total extinction. He explains how experts have been able to piece together fossil evidence to give us a picture of the dinosaur's life on earth. A variety of dinosaurs, including the flesh-eaters, armored reptiles and duck-billed species are discussed. Also discussed are the creatures that shared the dinosaurs' world such as the first mammals and winged reptiles. The author also delves into one of the greatest mysteries of the prehistoric past - the strange disappearance of the dinosaurs. Did they destroy themselves? Was their demise tied to a natural disaster? Or were these creatures victims of a deadly disease? These and other theories are discussed in detail in an attempt to unravel this mystery.
