3.0 out of 5 stars
Regretfully mediocre, March 5, 2004
I wish that I could be at all as enthusiastic in my evaluation of Sea Dragons as were those who wrote the dust jacket blurbs. I do not find Mr. Ellis's writing riveting, vivid and delightful, or readable and accessible. Sea Dragons managers to be both superficial and prolix. I find it poorly organized, diffuse, and repetitious, and I can only recommend it to someone who is desperately enamored with the Mesozoic Era.Ellis is an excellent artist, but his black and white illustrations are often not well posed to show the particular features he discusses in his text. There are few detail drawings to show the particularities of form, bone structure, dentition, or skin that he mentions. A few drawings look to be at odds with his text. Ellis's text includes pairs of sentences where the second repeats the first with minor modification or elaboration as if he intended to discard the first but didn't. There are paragraphs that are dustbins of assorted sentences with no topic. There are paragraphs that change topic in mid stream. There are collections of paragraphs with neither topic sentences nor transitions between paragraphs. Sideshows are numerous and only wander back to the main topic with difficulty. Ellis uses long footnotes that should have been incorporated into the text. He does provide good translations for many of the species names. Most technical areas of anatomy or cladistics are dealt with by quoting a jargon-filled paragraph, noting its incomprehensibility to lay readers, and skipping on to something else. Ellis notes opposing viewpoints but does little to clarify which is to be preferred or why. There are no cladograms or old-style trees of proposed descent whatsoever. No group of Sea Dragons is dealt with in any specific order. There is very little paleoenvironmental information to make clear why a given animal is said to have lived in a particular setting, and only one or two illustrations supply any such information. Many of these problems might be attributed to inadequate editing. Sea Dragons is the first book I've read in ages that contains misspelled words as opposed to spell-checked misuses. The organizational and editing problems can be seen most obviously where Ellis discusses the mosasaur Globidens, a supposed bivalve-eating creature with rounded teeth. Globidens is mentioned five different times on different pages, but in detail with an illustration only the last time. At that point we are reminded that the ichthyosaur Grippia was also a presumed shellfish eater, but in the previous mention of Grippia, one hundred and forty-some pages earlier in the proper section on ichthyosaurs (Ellis truly loves ichthyosaurs; they turn up in every section), we were told twice only where Grippia was found. In the last section, Ellis first has plesiosaurs going extinct with the ichthyosaurs 20 million years before the K-T asteroid strike, then two pages later has them going extinct "around the K-T boundary," "about 65 million years ago." These would be small matters if they were isolated occurrences, but they are not. Ellis includes the obligatory attack against creationists in the middle of his section on ichthyosaurs. Creationists have such problems with truth and accuracy and there are so many obvious points on which to criticize the ludicrous nature of their views that it is embarrassing to have Ellis pointlessly write that "here we will assume quite the opposite" when his disorganization and omissions obscure the evidence for evolution marine reptiles do provide. Assumptions aren't good enough to overcome willful ignorance. Sea Dragons desperately needs a listing in each section of the species/genera discussed and those placed on a graph with location on one axis and time on the other. A side-by-side listing of European and North American geological divisions with radiometric dates should be included. The illustrations need a scale bar or human figure for comparison. For younger readers, certainly not Ellis's target audience, I would recommend any of David Norman's books that touch on marine reptiles, recognizing that he has little to say on Mosasaurs.
For adult readers, Christopher McGowan's Dinosaurs, Spitfires, & Sea Dragons or Richard Cowen's History of Life provide a more cogent though far briefer account of these truly great dragons of the seas. For those willing to brave the terminology and jargon, Ancient Marine Reptiles, Jack M. Callaway and Elizabeth L. Nicholls, eds., remains the most informative volume.

Going for a swim?, April 23, 2004
The next time you're setting up a putt on the ninth hole at Smoky Hill Country Club in Hays, Kansas, pause a moment. Glance around you at the arid hills and scattered vegetation. It's difficult to comprehend that where you're standing was once under hundreds of metres of sea water. Millions of years in the past most of what is now central North America lay beneath the great Niobrara Sea [better known as the Bear Paw Sea]. Nor would you feel lonely - it was inhabited by all manner of creatures. However, some of these rivalled in size and ferocity the great land-dwelling dinosaurs of the same period. Richard Ellis has started to fill a long-standing gap in revealing how these creatures likely lived. And perhaps why they are no longer with us. Ancient marine reptiles developed to immense sizes and bizarre shapes. Ellis focusses on the four major types, all of which had one commonalty - size. After a brief lesson on nomenclature and a dismissal of the Loch Ness enigma, he goes on to introduce us to some true monsters. And gargantuan they are! The fossils found in Britain and Belgium almost two centuries ago amazed the world with their likely size. Those revealed since, many from around Hays, Kansas, achieve lengths of up to twenty metres. In line with their massive bodies, some bore impressive dental equipment, with some teeth achieving twenty centimetres in length. Seeking prey at depth, they developed eyes the size of dinner plates. These were formidable creatures, indeed. Ellis compiles fossil evidence to develop a picture of marine reptile lifestyles. They were all predators, but shape, locomotion and capacity for diving to extreme depths combined to focus on particular niches. Some must have been a glorious sight [if they didn't see you!], literally "flying" through the water like penguins. Others undulated their bodies like snakes, although, as Ellis states, no snakes were present in the seas at the time. The ichthyosaurs seem to have resembled tunas in shape and motion. The most extraordinary were the long-necked plesiosaurs who may have been bottom feeders. The range of body types and swimming styles is a reflection of the long period of their dominance. They were successful enough to have occupied the full extent of the world's oceans of the time. There are a few quirks in this book the general reader should note. These reptiles maintained an imposing set of food processors and there's a challenge in demonstrating many factors in but one illustration. As Ellis notes often, how they appeared and how they lived relies much on what they ate. But, unlike the many illustrations he provides for dramatic effect, they didn't cruise the seas mouths agape. That's for fish with gills, not air-breathing reptiles. There's some irony in the illustration [p. 212] depicting a mosasaur swimming closed-mouthed, but bending its neck in a manner no large reptile with only seven vertebrae could achieve. These are, of course, minor issues and detract little from Ellis presentation. Still, as a learning resource for the non-paleontologists among us, it was incumbent on Ellis to use his wealth of information accurately. [stephen a. haines - Ottawa, Canada]

5.0 out of 5 stars
very nice survey of mesozoic marine life - recommended !, October 31, 2003
By A Customer
This is the first book I know that describes the whole variety of mesozoic marine life in a, for the averagely interested as well as experts, very clear and understandable manner. In four sections Ellis reflects the latest information on nearly all species of Ichthyosaurs, Plesiosaurs, Pliosaurs and Mosasaurs combined with a lot of outstanding life reconstructions (done by Ellis himself). The text is free of speculation but full of scientific background because Ellis frequently includes the latest inputs from the leading experts. What the book also makes very enjoyable is the fact, that the book is free of difficult technical jargon but gives a lot of references for people that are looking for these technical details. The style and print quality of the book is also very good.
In summary one can say confidently that this book is the best popularized book on mesozoic marine life available
