Discover the biggest creatures to have roamed the Earth, past and present, from the outright biggest – such as the colossal blue whale and the dinosaur Argentinosaurus – but also species that grew to monstrous sizes compared to others of their kind, such as the giant kangaroos of Australia, a beaver the size of a bear, and Pelagornis, a giant bird with a wingspan almost as long as a bus!

You'll meet the giants of the forest, plains, rivers, sea and sky through vibrantly illustrated scenes of them in their natural habitats and compare the size of these humongous creatures to humans. A gatefold spread unfolds to reveal a visual timeline showing when they roamed the Earth.
