This amazing, informative book displays all the huge, wild creatures that existed during the last Ice Age! The Ice Age started around two and a half million years ago, when our planet was covered in ice sheets. Oceans froze, forcing some animals to extinction, but some fearsome Ice Age giants survived and roamed the Earth. Giant sloths fought off saber-toothed cats, and huge birds owned the skies. Mammoths walked across ice bridges over parts of the ocean frozen by the cold climate. The beasts of that time were truly enormous, weird, and wonderful, and kids will love learning about them in this book, complete with beautiful illustrations and gatefolds!
