Great book, March 14, 2006
I've read several dinosaur books and I've generally found them to be very good. This one, along with "The Complete Dinosaur", ranks as one of my favorites. The reason I was interested in this book was that I was looking for something that focused on the evolution of dinosaurs and how the various taxa of dinosaurs related to each other. I was also looking for something at an intermediate level. This book exceeded my expectations on all fronts.
The first two chapters mainly covered background material such as geological time scales, isotopic dating and fossilization. The next two introduced some concepts of evolution (not including natural selection, an understanding of this is presumed) and a very high level view of chordates. The discussion of clade diagrams was very through.
After a chapter on the origin of dinosaurs, the book goes on devotes the next several chapters to describing a wide variety of dinosaur taxa and how they are related to each other. The chapters are grouped into parts, each part starts off with some high level discussion of a taxon. Then the individual chapters go on to elaborate the points by describing the taxa within the taxon. The chapters usually start with a description of the taxa's anatomy, distribution and behavior. Typically a fairly coarse grained clade diagram is presented early and more fine grained diagrams are presented as the chapter continues. The characteristics that distinguish one taxa from another are also described. The material isn't just presented as facts, it is justified by evidence from the fossil record. I liked the level of detail the authors typically chose, however someone else may want more or less.
The final two chapters of the theropod part deal with the evolution of birds. I found the discussion of the origin of feathers to be very good. I especially enjoyed the illustrations (I thought the illustrations throughout the book were quite good) showing how they evolved and the structure of feathers used for flying versus those primarily useful for insulation.
The remainder of the book deals with dinosaurs as a whole. I thought the chapter on thermoregulation was very good, much of the information being useful for studying animals in general, not just dinosaurs (the same could be said for several other parts of the book too). Following the thermoregulation chapter there is a chapter on patterns in dinosaur evolution that I thought really tied the previous material in the book together. The treatment of non-avian dinosaur extinction was excellent and balanced.
My one quibble about the content concerns what I consider to be an omission. The authors address the question of "is a cow a fish". They naturally answer "yes". In my opinion it would have been nice if they had then gone on to discuss this in more detail, explaining how this means fish don't form a clade. This would have been a good opportunity to discuss the concept of a grade and perhaps paraclade too. The reason I this discussing fish as a grade is important is that basically everybody has an idea that there is a group of animals they can classify as fish and this group doesn't include cows. I think it would've been nice to help them understand what they mean when they think of fish and why it doesn't conflict with the statement "a cow is a fish".
There are a couple errors, but they are easily recognized. For example on page 77 they refer to synapids as reptiles then on the following two pages they break up amniotes into synapsids and reptiles. Maybe I'm missing something, but it seems like a contradiction.
As much as I liked this book it's not for everyone (what book would be?). Obviously it's not cheap. If you're not interesting in dinosaur cladistics this book probably is not a great choice. If your main interest is more along the lines of a dinosaur catalog with descriptions of various dinosaur ways of life you can certainly find better books, especially at the price (although I still think this would be a good book). However, if you are interested in dinosaur evolution, along with how dinosaurs made their way in the world, then I think this is a great book.

outstanding, May 17, 1998
As an avid dinosaur buff, this undergraduate level textbook is a mandatory part of one's collection. The text is very readable yet complete, filling a void between child-oriented dinosaur books and books written for professional paleontologists. I must confess I could not put the book down. Although it is several hundred pages in length, I read the book in less than a week. Topics range from basic dinosaur paleontology to special subjects such as the evolutionary relationship between dinosaurs and birds. If you are a dino-phile, this textbook is a must-read.Brett J.

Clades of the past, September 20, 2005
"Dinosaur!" The word still makes children's faces bright with excitement. "Can we go to the museum, Dad?" - and a golf game is set aside. The authors note how pervasive the dinosaur has become in our society. We live in "dinosaur-crazy times with documentaries, colouring books and films - "we have thrice feasted on Jurassic Park movies". The authors feel this familiarity is all to the good - we learn something of Nature's ways from some of this exposure. They want us to take the next step and learn something of what the professional paleontologist does to bring the wealth of information about dinosaurs to our ken. We also need to understand what conditions prevailed while dinosaurs dominated the planet for 160 million years. That's a real success story and it deserves our attention.
In presenting their story of these impressive animals, the authors start with the general environment. Dating rocks is a fundamental aspect of how dinosaurs developed over time. The explain the science of "chronostratigraphy" using the classical examples of layered rock and moving on to how radioactive isotopes provide dating. They portray what an organism goes through in the process of fossilisation, and how fortunate we are to have anything to assess. Continental drift, which at once complicates and explains what would otherwise appear as anomolies, adds background. Climate is a further tool to explain how the creatures studied lived at the time.
With this background provided, they move on to depict the origin of dinosaurs. It's not a simple picture, as these "terrible lizards" didn't engage in a "takeover" of the planet as a given. It was a long, slow process from small beginnings. The first fossils, named by Darwin's major nemesis, Richard Owen, were an enigma. Years of study and conjecture led to the beginnings of dinosaur classification. The years of "the bone wars" in North America provided much insight into dinosaur development and diversity. As the story unfolds, the authors turn to an organisational method known as "cladistics". Clade diagrams demonstrating relationship between organisms are used to link more recent forms with their ancestral roots. It's an effective method, requiring only visible physical traits to establish the relationships. That, however, remains its greatest limitation and the source of enduring controversy.
Each segment of the book depicts a type - Stegosauria with their massive back plates, Ceratopsia with their massive horns and frilled skulls and Theropoda, "nature red in tooth and claw". The types are described in detail, with an anatomy lesson provided for the type. The evolution of each is traced, with additional material on eating habits, social make-up and how they attacked or defended themselves. Capping each section is an account of how each was first discovered, with biographies of the major figures in paleontology appended. In this second edition, the book updates the information gathered in the past decade. The update shows how the profession of palaeontology has expanded and enriched our knowledge. With lavish illustration by John Sibbick, the presentation is flawless, providing a wealth of new and detailed information.
Palaeontology is not without its disputes, and the authors carefully explain the issues, the scientists holding disparate views and how these are likely to be resolved. Among the enduring issues are whether dinosaurs were warm-blooded and the relationship between them and modern birds. The authors are unequivocal in their stance on these debates, sustaining their case on the available evidence. Their approach gives full voice to the disputants in these controversies, providing complete assessment of the data.
The book is a treasure for anyone interested in these animals that loomed so large in the history of life on our planet. Given the environmental, dietary, body structure and development information provided here, another edition will likely be some time in appearing. If your child mentions the word "dinosaur", have this book handy for answering their questions. And when they ask you to defer your golf match for a trip to the museum to see the reconstructions of these mighty, and not so mighty, animals, donate the time without remorse. You, too, may see them again with a child's eyes. But you will be prepared for what you'll be seeing. [stephen a. haines - Ottawa, Canada]
