Not every prehistoric creature is a dinosaur! Long, long ago, many strange beasts roamed the Earth, and this delightful picture book, based on the fossil halls at the American Museum of Natural History, tells their story. Fun, fact-filled verses introduce 16 animals (including eleven non-dinosaurs), creating a guessing game about who the subject might be. Meet the Smilodon (saber-toothed cat), woolly mammoth, prehistoric shark, and other creatures.
