The fierce sabertooth cat comes to life in a large, lavishly illustrated trade paperback! The Ice Age Sabertooth kept its most formidable weapon right in its mouth: a pair of enormous curved teeth with serrated edges like steak knives--as long and sharp as the teeth of a Tyrannosaurus rex! It was one of the fiercest cats to ever live. And because so many sabertooth cats died in the asphalt pools of what is now known as Rancho La Brea in Los Angeles, scientists know more about them than any other prehistoric cat. Ice Age Sabertooth tells the story of these ferocious predators--how they lived, hunted, and killed their prey, and what they may have looked like. In this second book in the Ice Age Animals series, stunning illustrations by acclaimed artist Mark Hallett, full-color photographs, fascinating maps, and informative diagrams bring the fierce sabertooth cat--and the world it lived in--to life.

Find out how animals lived, fought, and died during the Ice Age.
