Here's a wonderful opportunity to take a trip back in time and discover the awesome array of prehistoric mammals that roamed the Earth millions of years ago. This book contains 41 detailed, ready-to-colour illustrations (including four double-page drawings) depicting giant bears, saber-toothed cats, tiny rodents, and dozens of other creatures now known only by their fossil remains.Award-winning artist Jan Sovak has meticulously rendered - in roughly chronological order - over 40 species as they might have appeared in their natural habitats. Included are the Basilosaurus, a slim, snake-like whale; the Megistotherium, twice as large as a polar bear and probably the largest flesh-eating mammal that ever lived; the Borophagus, a large dog that preyed on small primitive horses in North America six million years ago; Ursus spelaeus, the great cave bear; the giraffe-like Indricotherium, and ancestor of the rhinoceros that browsed on the tops of trees; Mammuthus primigenius, the legendary woolly mammoth, and many more.Carefully researched captions describe the animals, providing names, where found, size, diet, habitat, and more. Thirteen full-colour illustrations appear on the book's covers and suggest possible colourations. This colouring book will intrigue young students of prehistory and evolution; artists and craftspeople will find the volume an inexpensive source of royalty-free illustrations.
