"Trilobites are the most lifelike of fossils—many well-preserved specimens belie their great antiquity and seem almost ready to arch their bodies, peer about with their compound eyes, and crawl forward as if to complete a journey that was interrupted hundreds of millions of years ago."—from the Foreword"New York State is and has long been a magnet for trilobite hunters. . . . New York's trilobites were among the first illustrated fossils in North America. . . . Many outstanding localities in New York State, from the majestic Ordovician limestone bluffs of Trenton Falls, to the Silurian beds in the great gorge of Niagara River, to the Devonian shale cliffs of Lake Erie, continue to yield abundant and spectacular trilobite fossils. New York strata have also yielded more trilobites with preserved appendages and other "soft parts" than almost any other region of the world. . . . Spectacular, ornate trilobites from New York ranging from a few millimeters to nearly a half meter in length, are featured in museums all over the world."—from the PrefaceThis superbly illustrated book reviews the trilobite fossils found throughout New York State, including their biology, methods of taphonomy (preservation of specimens), and the broader Paleozoic geology of the state. A general chapter on the geology of New York State places the importance of these now-extinct invertebrate marine animals into context. Sixty-seven line drawings and 175 black-and-white photographs illustrate individual species, many represented here by type specimens, and display the eerie beauty that has made New York State trilobites favorites of collectors the world over.

A photographic guide to Oklahoma’s Devonian trilobites. The geological history of Coal County, Oklahoma. Descriptions of rock formations where trilobites are found. Excavation and restoration of trilobites. A photographic atlas of the Lower Devonian trilobites of Oklahoma, with helpful information to aid in their identification. Trilobites are a well-known fossil group, possibly second most famous only to dinosaurs. With their easily fossilized exoskeleton, they left an extensive and diverse fossil record. They began a drawn-out decline to extinction during Late Devonian time, when all but one of the trilobite orders died out. This meticulously researched reference guide is a photographic atlas and descriptive compendium on the trilobites of Coal County, Oklahoma. The species described lived during the Lower Devonian in a shallow tropical ocean that had advanced over the landscape of North America. More than twenty species are exquisitely preserved in Oklahoma’s limestone rocks. Each species is carefully illustrated, including thorough descriptions, so that those familiar and unfamiliar can understand and appreciate these amazing creatures. The most current scientific research on these trilobites is also included. For those wishing to pursue a deeper interest in trilobites, a comprehensive bibliography lists hundreds of sources of information for further study.

NATURE-STUDY is, despite all discussions and perversions, a study of nature; it consists of simple, truthful observations that may, like beads on a string, finally be threaded upon the understanding and thus held together as a logical and harmonious whole. Therefore, the object of the nature-study teacher should be to cultivate in the children powers of accurate observation and to build up within them, understanding. FIRST, but not most important, nature-study gives the child practical and helpful knowledge. It makes him familiar with nature’s ways and forces, so that he is not so helpless in the presence of natural misfortune and disasters. Nature-study cultivates the child’s imagination since there are so many wonderful and true stories that he may read with his own eyes, which affect his imagination as much as does fairy lore; at the same time nature-study cultivates in him a perception and a regard for what is true, and the power to express it. All things seem possible in nature; yet this seeming is always guarded by the eager quest of what is true. Perhaps, half the falsehood in the world is due to lack of power to detect the truth and to express it. Nature-study aids both in discernment and expression of things as they are. Nature-study cultivates in the child a love of the beautiful; it brings to him early a perception of color, form and music. He sees whatever there is in his environment, whether it be the thunder-head piled up in the western sky, or the golden flash of the oriole in the elm; whether it be the purple of the shadows on the snow, or the azure glint on the wing of the little butterfly. Also, what there is of sound, he hears; he reads the music score of the bird orchestra, separating each part and knowing which bird sings it. And the patter of the rain, the gurgle of the brook, the sighing of the wind in the pine, he notes and loves and becomes enriched thereby. But, more than all, nature-study gives the child a sense of companionship with life out of doors and an abiding love of nature. Let this latter be the teacher’s criterion for judging his or her work. If nature-study as taught does not make the child love nature and the out-of-doors, then it should cease. Let us not inflict permanent injury on the child by turning him away from nature instead of toward it. However, if the love of nature is in the teacher’s heart, there is no danger; such a teacher, no matter by what method, takes the child gently by the hand and walks with him in paths that lead to the seeing and comprehending of what he may find beneath his feet or above his head. And these paths whether they lead among the lowliest plants, or whether to the stars, finally converge and bring the wanderer to that serene peace and hopeful faith that is the sure inheritance of all those who realize fully that they are working units of this wonderful universe.

The horned dinosaurs, a group of rhinoceros-like creatures that lived 100 to 65 million years ago, included one of the greatest and most popular dinosaurs studied today: Triceratops. Noted for his flamboyant appearance--marked by a striking array of horns over the nose and eyes, a long bony frill at the back of the head, and an assortment of lumps and bumps for attracting females--this herbivore displayed remarkable strength in its ability to fight off Tyrannosaurus rex. It was also among the last dinosaurs to walk the earth. In telling us about Triceratops and its relatives, the Ceratopsia, Peter Dodson here re-creates the sense of adventure enjoyed by so many scientists who have studied them since their discovery in the mid-nineteenth century. From the badlands of the Red Deer River in Alberta to the Gobi Desert, Dodson pieces together fossil evidence to describe the ceratopsians themselves--their anatomy, biology, and geography--and he evokes the human dimension of their discovery and interpretation. An authoritative survey filled with many original illustrations, this book is the first comprehensive presentation of horned dinosaurs for the general reader. Dodson explains first the fascinating ways in which the ceratopsians dealt with their dangerous environment. There follows a lesson on ceratopsian bone structure, which enables the reader quickly to grasp the questions that still puzzle scientists, concerning features such as posture, gait, footprints, and diet. Dodson evenhandedly discusses controversies that continue, for example, over sexual dimorphism and the causes of the dinosaurs' disappearance. Throughout his narrative, we are reminded that dinosaur study is a human enterprise. We meet the scientists who charmed New York high society into financing expeditions to Mongolia, home of Triceratops' predecessors, as well as those who used their poker winnings to sustain paleontology expeditions. Rich in fossil lore and in tales of adventure, the world of the Ceratopsia is presented here for specialists and general readers alike.

This book presents a quantitative treatment of the theory and natural variations of light stable isotopes. It discusses isotope distribution in the context of fractionation processes, thermodynamics, mass conservation, exchange kinetics, and diffusion theory, and includes more than 100 original equations. The theoretical principles are illustrated with natural examples that emphasize oxygen and hydrogen isotope variations in natural waters, terrestrial and extraterrestrial rocks, and hydrothermal systems. New data on meteoric precipitation, rivers, springs, formation fluids, and hydrothermal systems are included in relation to various natural phenomena. Essentially, this book seeks to reconnect the diverse phenomenological observations of isotope distribution to the quantitative theories of physical chemistry and the language of differential equations. It may serve as a textbook for advanced students, as a research reference, or as a quick source of information. The book is organized into five chapters, each followed by suggested quantitative problems and a short reference list. The three theoretical chapters progress from an elementary review of the physical chemistry of stable isotopes, to the thermodynamics of isotopic compounds, and finally to the calculation of isotope distribution in dynamic systems. The third and fifth chapters emphasize oxygen and hydrogen isotope variations in Earth's hydrosphere and lithosphere, constituting the most important examples of the theoretical principles. Appendices provide data on atomic weights of light elements, physical constants, mathematical relationships, and isotopic fractionation factors.

With Trilobite, Richard Fortey, paleontologist and author of the acclaimed Life, offers a marvelously written, smart and compelling, accessible and witty scientific narrative of the most ubiquitous of fossil creatures. Trilobites were shelled animals that lived in the oceans over five hundred million years ago. As bewilderingly diverse then as the beetle is today, they survived in the arctic or the tropics, were spiky or smooth, were large as lobsters or small as fleas. And because they flourished for three hundred million years, they can be used to glimpse a less evolved world of ancient continents and vanished oceans. Erudite and entertaining, this book is a uniquely exuberant homage to a fabulously singular species. From the Trade Paperback edition.

Few aspects of American military history have been as vigorously debated as Harry Truman's decision to use atomic bombs against Japan. In this carefully crafted volume, Michael Kort describes the wartime circumstances and thinking that form the context for the decision to use these weapons, surveys the major debates related to that decision, and provides a comprehensive collection of key primary source documents that illuminate the behavior of the United States and Japan during the closing days of World War II. Kort opens with a summary of the debate over Hiroshima as it has evolved since 1945. He then provides a historical overview of thye events in question, beginning with the decision and program to build the atomic bomb. Detailing the sequence of events leading to Japan's surrender, he revisits the decisive battles of the Pacific War and the motivations of American and Japanese leaders. Finally, Kort examines ten key issues in the discussion of Hiroshima and guides readers to relevant primary source documents, scholarly books, and articles.

Trilobites lived for over 300 million years in the seas of the world, and the remains of their hard parts have long attracted collectors. This new, definitive study - plates and text in equal measure - focuses on kinds of trilobites from rocks of all the Palaeozoic periods in a series of more than 120 first-class photographs, with complementary text. These include rare specimens which have preserved soft parts such as antennae and limbs; from these the anatomy may be reconstructed, and one may speculate on the way trilobites behaved. The calcified trilobite shell was outside the body, hence had to be cast at intervals as the animal grew. Specimens from these intervals show how the trilobite changed in form as it grew from a tiny early stage to a length of several centimetres. The great succession of kinds of trilobites evolved in a world of changing geography and climate. How trilobites were preserved, the kinds of rocks in which they occur, and traces of their activity, are described in order to infer where they lived in ancient seas and their manner of life. Some kinds were world-wide in distribution, others limited to seas of differing depth or temperature. This record in the rocks of different continents shows that new kinds arose to replace extinct forms, in many cases abruptly, and that particular trends of change occurred repeatedly. Mechanisms which may have effected these changes are discussed. The long-continued search for evolutionary links between kinds of trilobites, as the basis for a natural classification, is reviewed in the light of conflicting contemporary ideas.
