'...it is most important to have a work covering the study of ice-age amphibians and reptiles by the doyen of Pleistocene herpetologists,...this pioneering book covers all important aspects of Pleistocene North American herpetology...such a study has been needed for many years. It is written clearly and will be of great value to North American Pleistocene paleontologists, zooarchaeologists and paleoecologists, as well as modern herpetologists. It would serve well as
a university text.'
