That's the way all popular science books should be written. With a firm structure and rigorous methodology of presenting information, but in a clear and elegant style, accessible to all interested readers.
Pterosaurs have been getting a raw deal, from the publicity point of view, since they have been depicted, more or less, as sky decoration for dinosaur dioramas, as the author points out. Not any more. New and exciting discoveries all over the globe, but particularly in China and South America, have put a lot of new meat in the bones of the Pterosaur evolutionary history. And have allowed scientists to form more accurate hypotheses on the physiology and ecology of these long-lost animals.
The author begins with a history of Pterosaur fossils discoveries and how these have enabled us to construct their family tree, tracing their evolution from tiny insect eaters 10-20 cm across of the Triassic, to the generalist giants with wingspans of 10 m at the end of the Cretaceous. The Pterosaur anatomy is given a thorough description, with particular attention given to wing bones and membranes and the magnificent head crests, spectacular trademarks of many Pterosaur species. And then comes the real fire: physiology of reproduction and development and, of course, flight mechanics.
Combining all these data, the final chapters attempt to sketch out the various phases of the Pterosaur story and the place these animals carved for themselves in Mesozoic ecosystems. The author admits that much of the tale is conjectural but things are certainly on a much firmer foot than a decade ago and are getting better all the time.
With its wealth of new information, neat and graceful writing style and impressive illustrations, the book is a must-have for anyone interested in prehistoric life and the Mesozoic in particular.
