The secret lives and amazing adaptations of past creatures are revealed in this beautifully illustrated compendium of Earth's long-gone beasts. Buried far beneath the ground are secret stories of ancient lands. Stories from a time when dinosaurs with tails as big as whales towered over trees, birds had teeth, and super-fast sharks with saws for jaws swam through oceans and seas. Earth's amazing animals may be lost in time, but they are no longer forgotten. From dinosaurs and sea beasts, to giant bugs, birds and Ice Age mammals, these spectacular species were once to be seen stomping, roaring, soaring and crawling across land, sky and sea - but are now extinct and lost forever. In this beautifully illustrated follow-up to Secret Stories of Nature, you can uncover the fascinating histories of Earth's most astounding extinct animals, from iconic beasts such as Tyrannosaurus rex, the woolly mammoth and the dodo, to jaw-dropping creatures such as a dragonfly-relative the size of a pigeon and a tiny sea beast that looked like a cartoon character.
