Nearly three million years ago the Ice Age began. Oceans froze, ice sheets covered land and animals, along with humans, found ways to thrive. These prehistoric creatures were weird, wonderful and enormous. Explore the Earth continent by continent and come face to face with Ice-Age megafauna, such as North America’s short-faced bear – which was 3.7 metres tall, and mastodons – which weighed twice as much as a T. rex! Accompanying the images, lively text allows you imagine exactly what these mega animals were like!
