Not every prehistoric creature is a dinosaur! Long, long ago, many strange beasts roamed the Earth—and this delightful picture book, based on the Halls of Fossil Vertebrates at the renowned American Museum of Natural History, tells their story. Fun, fact-filled verses introduce 16 animals—eleven that are not dinosaurs, five that are—creating an irresistible guessing game about who the subject might be. Meet theSmilodon (a saber-toothed cat), the woolly mammoth, the prehistoric shark, and other creatures.
