Uncover the fascinating secret lives and incredible adaptations of Earth's ancient creatures in this beautifully illustrated compendium. Buried deep within the Earth's layers lie stories from an age when dinosaurs the size of whales roamed, birds had teeth, and sharks with saw-toothed jaws patrolled the seas. Discover extinct beasts like the mighty T. rex, woolly mammoths, and the dodo, alongside lesser-known creatures like giant dragonflies and quirky sea beasts. Learn how scientists piece these stories together from fossil records, and how we can protect today's endangered species and their habitats. A perfect family gift book!
