This book presents the general features and conclusions of the successful Amherst Expedition to Patagonia. Many photos and drawings are used to illustrate the findings of the fossil hunt. A good read for anyone with an interest in archeology and natural history. Originally published in 1913. Many of the earliest books, particularly those dating back to 1900s and before, are now extremely scarce and increasingly expensive. We are republishing these classic works in affordable, high quality, modern editions, using the original artwork and text.
