Baby Coelophysis

Each of these small egg-shaped books breaks open to reveal a different baby dinosaur pop-up. A surprisingly lively, fact-filled mini-book (12 pages) is also contained within the sturdy card-stock pages. The art is the series' most arresting feature: the bright watercolors are highly detailed and well-matched with the unusually dynamic yet small-scale paper engineering. An engaging, reasonably priced set. Ages 4-8. (Sept.)
