Product Information

There were two main groups of dinosaur - the Saurischia, which had hipbones arranged like a lizard's, and the Ornitischia, which had hipbones arranged like a bird's. Early dinosaurs were among the first animals to evolve legs for supporting great weight or moving fast to catch prey or escape enemies. Dinosaurs are a diverse group of reptiles that were the dominant terrestrial life form on Earth during the Mesozoic Era, about 245 million years ago. The book also contains spreads on how fossils are made, how they are discovered, and the process of evolution. The first description of dinosaurs as a separate group of life forms (known as “Dinosauria”) was published in 1842 by British paleontologist Richard Owen, who based his findings on fossil fragments of the Cladeiodon and the Cetiosaurus.

The book is generously illustrated with many detailed drawings and photographs, and includes color pictures and illustrations that feature interpretations of the best known and most important animals.

Learn everything there is to know about dinosaurs in this book brimming with facts about the prehistoric world. Two years before the Maidstone Iguanodon came to light, a different kind of skeleton was found in the Weald of southern England.But some people argue that Allosaurus and its kind would have been too slow and weak to overpower the giant plant-eaters, and were scavengers, feeding on dinosaurs already dead. Both men collected fossils as an avocation and are credited with the earliest published announcements in England of what later would be recognized as dinosaurs.
