DINOSAUR MUMMIES

Despite some minor bobbles, young dinosaur fans will latch onto this heavily illustrated report like starving velociraptors at a picnic. The indefatigably enthusiastic Halls writes with two purposes in mind: to recount the discoveries and natures of dinosaur fossils that include not just bones, but remnants of “skin, hearts, muscles and goop-filled stomachs”—not to mention feathers and a variety of less durable tissues; and to introduce many of the paleontologists who have made, or are making, those discoveries. She highlights six finds in particular, but mentions many more, nearly all of which get at least one photo, and closes with enough references to relevant books, videos, DVDs, Web sites, and public “digs” to satisfy the most demanding dinophile. Spears supplements the photos with cartoon scenes of reconstructed specimens, and Carpenter contributes an essay on the importance of the just-discovered duckbill dubbed “Leonardo.” Though two photos are repeated and the portrait gallery of scientists is capped with a profile of eminent specialist Dr. Karen Chin, in which she’s labeled “a girl who loves digging up dinosaur doo doo,” this is definitely a must, as useful as it is entertaining.
