The Ordovician and the Silurian
This hardcover concertina book folds out to a 108 in panorama depicting the giant invertebrates that dominated the seas 480 million years ago. Not just an art book, the book also explains the major events of the period in simple language. Printed on heavy card stock, the concertina, can be removed from its hardcover casing to be displayed. Each book in the Paleozoic series (5 books total) can be joined to create a 42 feet long image showing the evolution of life on earth. Each cover is debossed with a fossil of an animal from the period.
