The author covers the five Platonic solids (cube, tetrahedron, octahedron, icosahedron and dodecahedron). There are ample variations with different color patterns and sunken sides. Dipyramids and Dimpled Dipyramids, unexplored before this in Origami, are also covered. There are a total of 64 models in the book. All the designs have an interesting look and a pleasing folding sequence and are based on unique mathematical equations.

In this fascinating collection of origami projects, John Montroll, one of America’s foremost origami artists, teaches you to create models of the world’s most celebrated extinct animals, each folded from a single square sheet of paper. Paper crafters can make amazingly detailed paper replicas of the Tyrannosaurus, the Stegosaurus, the Pterodactylus, the Triceratops, the Apatosaurus, and many of the other monsters that seize the imaginations of children and adults alike.

This third edition in full color with 24 prehistoric models includes the Woolly Mammoth. Each project is accompanied with notes of the animal being represented. Anyone interested in dinosaurs or origami will find this book fascinating and entertaining.
