This engaging richly illustrated picture book is the perfect introduction to Alaska's dinosaurs. It opens with an irresistible, jam-packed map of Alaska fossils, and then proceeds through a timeline of prehistoric creatures that inhabited ancient Alaska's oceans and forests.

Discover thalattosaurs, giant sea lizards who lived over 200 million years ago, and the mysterious "desmos," a prehistoric marine mammal that looked like a hippo but might be related to horses and rhinos and roamed the region 20 million years ago, and many more!
