Step into an incredible lost world and marvel at the strange and magnificent creatures that once roamed our Earth. From the awe-inspiring woolly mammoth and the ferocious Spinosaurus to the shy Chinese river dolphin and incredibly rare Pinta Island tortoise ‘Lonesome George’, meet 35 extinct species and discover how these creatures came under threat. Featuring additional information on ‘Lazarus species’ (animals declared extinct but which, amazingly, have been rediscovered in the wild), and mass extinction events, including the part we are playing in endangering our wildlife, the book shows young readers that extinction is not simply a part of ancient history – it is happening right now across the planet – but that if we all make some small changes to our lifestyles, our wonderful species can be saved. With beautiful and vibrant illustrations throughout, this stunning large format compendium is a reminder of the remarkable animals we have lost, as well as a celebration of those that have returned from the brink of extinction.
