A book about dinosaurs folded from paper, a simple idea, really. But take a deeper look, and this is one of the most engaging origami books on the subject ever-for that matter, perhaps it is one of the best origami books ever. I know it is one of my top ten books. Enough praise, you want to know what's in it. Well, as Montroll usually does, the beginning models are so easy, I think you could fold them from sheet metal...an egg, mountain, and tree. Soon though, the dinosaurs begin, and slowly but surely the difficulty rises, until culminating with a Stegosaurus. Other dinosaurs include, T-rex, a bunch of gliding dinos, and others such as Dimetrodon and Spinosaurus. I would recommend this to any Dinosaur fan, and/or origami fan. However, a true beginner would find this book to be boring, because after the three 'sheet metal' models, the difficulty rises 2 or 3 fold. If you can make the first 4 or 5, you can probably learn to make them all. In short, a great buy!
