"From the icy Arctic vastness to the steamy tropical swamps of Florida, people came upon a teeming variety of animals in North America after the Ice Age. The book travels the continent region by region, introducing fascinating and bizarre beasts including ground sloths, glyptodonts, mastodons, mammoths, saber-toothed and scimitar-toothed cats, and the short-faced bear.

Alongside these now-extinct animals were lions, cheetahs, zebras, and camels - animals that have long since disappeared from their North American homes - as well as species still seen today, such as caribou, grizzlies, eagles, salmon, bison, coyotes, prairie dogs, condors, alligators, and jaguars.".

"A wealth of fossil evidence informs the stunning computer-generated panoramas that fill the pages of the volume. Bones of the ancient beasts again have flesh and fur, unfamiliar animals again roam the landscapes, and the world of prehistoric North America comes startlingly to life."--BOOK JACKET.
