Paperback. Like new/unused. By Tom Tierney. From the publisher: “Colossal and teensy, swift and sluggish, these mammals tend to extremes. Thirty illustrations with detailed captions portray remarkable creatures of past and present, from extinct cousins of the rhinoceros to modern-day kangaroos, bats, and elephants. All bear extraordinary characteristics -- oversized claws and fangs, giant snouts, multiple horns, and other incredible features.”
