If you were thinking about buying this book for your kids or a dinofan friend, a word of advise: it mightbe a bit over their heads. This book is basically an amalgamate of scientific papers without any editorial instrusion; they are true scientific papers for scientists in the style of scientific journals. Though profusely illustrated, it is not a field guide with lots of recreations and dioramas which might be what most kids and dinofans would want. Most of the illustrations are maps of the areas where a sample fossil was found or drawings and pictures of actual fossil bone at the site where found. Only the turtles and crocodiles sections of the book have some recreations of the creatures; but you will not find a single recreation drawing of an ichthyosaur. For the scientific reader this is a definite 5 star, for most everyone it might be only 2 or 3 star.

The editors, Callaway and Nicholls, have assembled 17 papers describing the results of current research by the experts on the various groups of extinct marine reptiles (Ichthyosaurs, Plesiosaurs, Turtles, Mosasaurs and Crocodiles), and their associated faunas, behavior and evolution. Well researched and profusely illustrated, this book is a must read for those seriously interested in the biology, ecology and paleontology of this diverse and fascinating group of animals.
