The ideal textbook for non-science majors, this lively and engaging introduction encourages students to ask questions, assess data critically and think like a scientist. Building on the success of previous editions, Dinosaurs has been thoroughly updated to include new discoveries in the field, such as the toothed bird specimens found in China and recent discoveries of dinosaur soft anatomy. Illustrations by leading paleontological illustrator John Sibbick and new, carefully-chosen photographs, clearly show how dinosaurs looked, lived and their role in Earth history. Making science accessible and relevant through clear explanations and extensive illustrations, the text guides students through the dinosaur groups, emphasizing scientific concepts rather than presenting endless facts. Grounded in the common language of modern evolutionary biology - phylogenetic systematics - students learn to think about dinosaurs the way that professional paleontologists do.

Titus Lucretius Carus was probably born in the early first century B.C., and died in the year 55. Little is known of his life, although two tantalizing bits of gossip were passed on by St. Jerome: that he was poisoned by a madness-inducing aphrodisiac given him by his wife, and that his great poem "On the Nature of Things" was posthumously edited by Cicero. For the latter assertion, writes Anthony Esolen in his introduction to the present volume, there is little evidence, and none whatsoever for the former.

What does survive is a masterful poetic work that stands as the greatest exposition of Epicurean philosophy. Writing in the waning days of the Roman Republic--as Rome's politics grew individualistic and treacherous, its high-life wanton, its piety introspective and morbid--Lucretius sets forth a rational and materialistic view of the world which offers a retreat into a quiet community of wisdom and friendship.

Even to modern readers, the sweep of Lucretius's observations is remarkable. A careful observer of nature, he writes with an innocent curiosity into how things are put together--from the oceans, lands, and stars to a mound of poppy seeds, from the "applause" of a rooster's wings to the human mind and soul. Yet Lucretius is no romantic. Nature is what it is--fascinating, purposeless, beautiful, deadly. Once we understand this, we free ourselves of superstitious fears, becoming as human and as godlike as we can be. The poem, then, is about the universe and how human beings ought to live in it. Epicurean physics and morality converge.

Until now, there has been no adequate English verse translation of Lucretius's work. Anthony Esolen fills that gap with a version that reproduces--with remarkable faithfulness--the meaning, pace, and tone of the original Latin.

Here is a book that will introduce a new generation of readers to a thinker whose powers of observation and depth of insight remain fresh to the present day.

"Esolen has the rare gift of being both a fine poet and a lover of languages. His diction is poetic and natural; he has a fine ear for sound, and the translation benefits greatly from being read aloud--as Latin poetry was meant to be. This translation is clear and forceful. It can, and will, be read."--Kenneth J. Reckford, University of North Carolina, Chapel Hill

When the "The Dinosauria "was first published more than a decade ago, it was hailed as the best scholarly reference work available on dinosaurs and an historically unparalleled compendium of information. This second, fully revised edition continues in the same vein as the first but encompasses the recent spectacular discoveries that have continued to revolutionize the field. A state-of-the-science view of current world research, the volume includes comprehensive coverage of dinosaur systematics, reproduction, and life history strategies, biogeography, taphonomy, paleoecology, thermoregulation, and extinction. Its internationally renowned authorsOCoforty-four specialists on the various members of the DinosauriaOCocontribute definitive descriptions and illustrations of these magnificent Mesozoic beasts. The first section of "The Dinosauria "begins with the origin of the great clade of these fascinating reptiles, followed by separate coverage of each major dinosaur taxon, including the Mesozoic radiation of birds. The second part of the volume navigates through broad areas of interest. Here we find comprehensive documentation of dinosaur distribution through time and space, discussion of the interface between geology and biology, and the paleoecological inferences that can be made through this link. This new edition will be the benchmark reference for everyone who needs authoritative information on dinosaurs."

Written for non-specialists, this detailed survey of dinosaur origins, diversity, and extinction is designed as a series of successive essays covering important and timely topics in dinosaur paleobiology, such as "warm-bloodedness," birds as living dinosaurs, the new, non-flying feathered dinosaurs, dinosaur functional morphology, and cladistic methods in systematics. Its explicitly phylogenetic approach to the group is that taken by dinosaur specialists. The book is not an edited compilation of the works of many individuals, but a unique, cohesive perspective on Dinosauria. Lavishly illustrated with hundreds of new, specially commissioned illustrations by John Sibbick, world-famous illustrator of dinosaurs, the volume includes multi-page drawings as well as sketches and diagrams. First edition Hb (1996): 0-521-44496-9 David E. Fastovsky is Professor of Geosciences at the University of Rhode Island. Fastovsky, the author of numerous scientific publications dealing with Mesozoic vertebrate faunas and their ancient environments, is also scientific co-Editor of Geology. He has undertaken extensive fieldwork studying dinosaurs and their environments in Montana, North Dakota, Arizona, Mexico, and Mongolia. David B. Weishampel is a professor at the Center for Functional Anatomy and Evolution at Johns Hopkins University, School of Medicine. Weishampel is best known for discovering, researching, and naming several rare European dinosaur species. During the 1980s Weishampel gained fame for his work with American paleontologist Jack Horner and later named the famous plant-eating, egg-laying Orodromeus, Horner. Now, a decade after his pioneering studies with Horner, Weishampel is most widely known for his current work on the Romanian dinosaur fauna. He is the author and co-author of many titles, including The Dinosaur Papers, 1676-1906 (Norton, 2003); The Dinosauria, (University of California, 1990); and Dinosaurs of the East Coast, (Johns Hopkins University Press, 1996).

The great dinosaur bone beds of the American and Canadian West are world famous and have yielded spectacular fossil finds. But the eastern United States and maritime Canada, where dinosaurs also roamed in great numbers, have been equally important to the study of these extraordinary creatures. Some dinosaur fossils have come from the bog iron and clay pits of Maryland and New Jersey, while others have been discovered in the riverbanks of North and South Carolina. Dinosaur footprint sites have been found from central Virginia to the Bay of Fundy in Nova Scotia.

In "Dinosaurs of the East Coast," David Weishampel and Luther Young restore East Coast dinosaurs to their rightful place on the paleontological map. They describe such dinosaurs as the plant-eating "Astrodon johnstoni," which browsed in a tropical Maryland jungle 100 million years ago; "Anchisaurus polyzelus," which lived in New England some 200 million years ago; "Eubrontes," the first large therapod on the East Coast; "Pekinosaurus olseni," a primitive ornithischian found in North Carolina; and "Hadrosaurus foulkii," a duck-billed dinosaur that lived in New Jersey some 70 million years ago. In addition, they chronicle the long and colorful history of dinosaur fossil hunting along the Atlantic coast and profile the modern-day fossil hunters--both professional paleontologists and amateur collecters--who continue to make important discoveries today. Richly illustrated with more than one hundred photographs and drawings, "Dinosaurs of the East Coast" combines science and history to offer a new look at an always fascinating subject.

The Ornithopoda, one of five suborders within the Ornithischia, was originally proposed by Marsh in 1881 to include those bipedal dinosaurs possessing a predentary bone fitted over the rostral end of the mandibles. Ornithopods as recognized today can be further characterized by moderately long facial skele- tons equipped with well-developed, often toothless premaxillae and moderate to large external nares. Maxillary and dentary dentitions vary but usually consist of at least one replacement series beneath the functional set; some have many rows of successional teeth. Tooth morphology suggests ornithopods were suc- cessful herbivores but, as will be discussed, the precise way(s) in which ornitho- pods chewed their food, hence lending important information about their tro- phic position, has not been settled. Postcranially, ornithopods show specializa- tion for bipedality in hindlimb construction and lack well-developed protective structures on their flanks, back, and tail. The Ornithopoda can itself be divided into five families: Fabrosauridae, He- terodontosauridae, Hypsilophodontidae, 19uanodontidae, and Hadrosauridae (subdivided into the subfamilies Hadrosaurinae and Lambeosaurinae). Both fabrosaurids and heterodontosaurids, first known from the Late Triassic and Early Jurassic of Argentina and South Africa, were small animals differing in details of cranial, dental, and appendicular anatomy. Fabrosaurids are be- lieved to represent the basal ornithopod stock (Galton 1972, 1978; Thulborn 1970a, 1972). During the Jurassic, ornithopods underwent major radiations that included the medium- to large-sized Hypsilophodontidae and the large- bodied Iguanodontidae, both of which survived into the Cretaceous.
