This book tells about hunting dinosaurs with a whisk broom; about the Thunder Lizard, which weighed 80,000 pounds; about armored dinosaurs, flying dragons, and sea serpents that lived 100 million years ago.

Here is a first-hand account of world-famous expeditions to the Gobi Desert, in northeastern Asia, to search for fossil remains of dinosaurs.

Dr. Roy Chapman Andrews, who died in 1960, was not only a scientist-explorer but also Director of the American Museum of Natural History.
