Reviews

"Each page is festooned with graphics, from photos and artistic renderings of the gigantic creatures to sidebars, pronunciation keys, and jokes... Beginning readers interested in branching out from dinosaurs into other ancient animals will likely find this both informative and entertaining." -- Booklist
