【The Tyranosaur jumps up from the page in a colorful, angry roar!!】 The Encyclopedia Prehistorica: Dinosaurs is not your typical dinosaur book. Created by master pop-up artists Robert Sabuda and Matthew Reinhart, the 3D pop-up designs are unlike anything I've ever seen before. Amazingly intricate and detailed, the dinosaurs really DO spring to life from the pages. Please don't be put-off when I inform you that the book only contains 12 pages (or 6 2-page openings), because each of those pages contains mini-books, often with their own pop-ups, for a grand total of 35 pop-ups in all. The design really is downright ingenious -- the largest pop-ups take up lots of space in the upper center of each page, and due to all the folded paper each page is quite bulky when the book is closed. That leaves lots of room, both horizontal and vertical, at the 4 corners of each page, and the authors utilized this space very well with their mini-book concept. Even the colors are stand-out. Each piece of paper that goes into one of the pop-ups is colored in such a way that it appears to have texture, adding both to the beauty and the complexity of each creature. You might think that, with all of the folded paper and mini-books on each page, that there would be lots of paper flopping around as you turn a page, but the book's creators were clever and included little tabs that you tuck the mini-book's pages into to keep them closed, keeping each page neat and tidy and flop-free as the page is turned. This book doesn't contain conventional pop-ups. It contains beautiful paper works of art!! The pop-ups are full 3-D characters made from layer upon layer of colorful cardboard. Not only is the artwork spectacular, but the text is fun and well worth reading in and of itself. The Encyclopedia Prehistoria: Dinosaurs is a real keepsake piece, and Im very pleased with this addition to the dinosaur section of our home library.★★★★★
