Dinosaurs: A Visual Encyclopedia

Gr 4–8—Like the 2011 edition, this revised version provides a wealth of well-organized, visually appealing content, with more than 200 species profiles mixed with overviews of broader groups and related topics. Some spreads introduce a family, such as hadrosaurs, followed by brief facts and images about several species from the group. Other spreads focus exclusively on a single species in more detail. Visuals include eye-catching digital images of prehistoric creatures in full, uncluttered layouts. Despite the "dinosaurs" in the title, coverage includes prehistoric reptiles, mammals, and invertebrates as well. Time lines, fact files, pronunciation guides, and scale diagrams offer further information in accessible formats. While much of the text and illustrations are identical to those of the earlier edition, significant changes based on up-to-date scholarship have been made. The description of the relationship between dinosaurs and birds, for instance, is more clear and decisive. Both the content and artwork reflect recent discoveries about physical features. Currency extends up to 2017, as reflected in the recent recognition of stenonychosaurus as a distinct species. Other changes include slight date adjustments based on the latest research and corrections of a couple minor errors from the earlier book.
