I don't know how I have missed this book, but it is a wonderfully written book on the subject of turtle biology, with outstanding coverage of all groups of turtles, including sea turtles and the pleurodira. The subjects are very well selected to cover the range of turtle biology, and the collection of photographs is outstanding and very well edited for high quality. I'm just grateful that places like Amazon carry this book, because it is likely that you will not find it anywhere else. Most other books on the subject focus on pet care or classification (naming) of turtles, but this book takes a profoundly original view of their biology. The chapter on paleonology is the best general account of the state of this subject anywhere. A terrific value, and you will not be disappointed!!
