I recently returned a copy of "Fossil Salamanders of North American" written by J. Alan Holman to my university library and thought a brief review was due. I got what I expected - detailed information on salamander paleontology like the fact that fossil salamanders were found dating back to the Early Jurassic Period roughly 150 million years ago. The book also provided a brief but very thorough introduction into the evolution of salamanders (particularly fascinating due to the recent discovery of fossil Gerobatrachus hottoni or elderly frog), ancient amphibians (apparently some were the size of a Volkswagen Microbus) and salamander biology (apparently neoteny played a major role in the evolution of salamanders).
