Part alphabet book, part catalog of species, part treasury of facts, this book is sure to delight young dinosaur lovers. In fact, the hardest part for librarians is not deciding whether or not to purchase it, but where to catalog it. A time line on the inside front cover shows the eras of the Earth, and then readers are off on a silly slide through an alphabet of dinosaurs. (And yes, there is a dinosaur for every letter, right down to Xuanhanosaurus, Yangchuanosaurus, and Zizhongosaurus.) Each page features an alliterative question along the lines of the title, accompanied by an appropriately wacky illustration, a pronunciation guide, and information about the species' era, range, size, and diet. Plant packs in an astonishing array of dinosaurs, from old favorites like Tyrannosaurus and Velociraptor to lesser-known varieties such as the spiky Kentrosaurus and the two-foot long Wannanosaurus. This title is ideal for young dinosaur aficionados who yearn for something new.–Kathleen Kelly MacMillan, Carroll County Public Library, MD Copyright © Reed Business Information, a division of Reed Elsevier Inc.
