Discover the largest creatures that have roamed the Earth, from the absolute giants – such as the colossal blue whale and the dinosaur Argentinosaurus – to species that grew to gigantic sizes compared to other members of their group, like the giant kangaroos of Australia, a heron the size of a bear, and the Pelagornis, a giant bird with a wingspan nearly as long as a bus! You will meet the giants of the forest, plains, rivers, sea, and sky through their vividly illustrated scenes in their natural habitat and compare the size of these enormous creatures with humans. A fold-out page reveals a visual timeline showing when they roamed the Earth.
