A mystery, vistas, camels, a sandstorm, and dinosaurs...what more could a young dreamer want? The Gobi Desert, Mongolia: "A land of secrets, " says Dr. Roy Chapman Andrews. He's talking in his jovial way to Walter Granger, a paleontologist, and George Olsen, their assistant, a young man whose surprising discovery made scientific history. Andrews led five expeditions across the Gobi for the American Museum of Natural History. This book chronicles those of 1922 and 1923, when he took with him some twenty men and an unlikely fleet of cars as an alternative to the more traditional camels. Originally expected to unearth signs that man had originated in Asia, these explorations stumbled across an unexpected find. And George did the stumbling-down the Flaming Cliffs near Shabarakh Usu, where dinosaurs roamed eighty million years ago. The find was a delicate egg, heavy as stone now and the answer to an old mystery: Dinosaurs were not born; they were hatched! A route map, a time line, crisp text, and breathtaking pictures present the sequence and excitement of bone-finding and preserving in the field for young readers eighty million years later.
