These are happy hunting days for lovers of dinosaur paraphernalia. As such, the Macmillan encyclopedia has something for everyone: colored reconstructions of the animals matched with a text whose style is accessible to most enthusiasts but whose content is extensive enough for more serious students. Both newly discovered and classic fossil animals are included, and there is background information to put each animal in time, place, and taxonomic perspective. The book's strongest feature is its inclusion of vertebrate animals other than dinosaurs. The variety of fossil fish and mammals should convince the skeptical that dinosaurs had no monopoly on bizarre structure.
