A highly illustrated celebration of dinosaurs for general readers, presenting a thorough survey from the earliest discoveries to contemporary controversies over extinction. Chapters are written by experts in fields including functional morphology, paleobiology, and biogeography, with sections on the discovery of dinosaurs, the study of dinosaurs, groups of dinosaurs, their biology, and dinosaur evolution. Highlights include discussion of new information on the warm-blooded/cold-blooded debate, new insights into the possibility of isolating dinosaur DNA, and a special section on dinosaurs in the media. While touted as accessible, treatment is sophisticated and assumes an educated and highly motivated readership. Includes a glossary, and bandw and color photos, drawings, paintings, and diagrams.

As scientific analysis of testable hypotheses has replaced the speculative approach to study of bone disease in recent and fossil amphibians and reptiles, the field has advanced from simply reporting observations to analyzing their implications. This process is predicated upon a reproducible data base which explains/diagnoses the nature of bony alterations and a secure review of the literature. Thereby hangs the rub. The herpetological literature are difficult to access (let alone read) and are scattered through many prominent and eclectic journals and in the lay literature. While older diagnoses often have not stood the test of time, the clarity of report descriptions usually allows confident identification of the underlying pathology.
Easily distinguished by the horns and frills on their skulls, ceratopsians were one of the most successful of all dinosaurs. This volume presents a broad range of cutting-edge research on the functional biology, behavior, systematics, paleoecology, and paleogeography of the horned dinosaurs, and includes descriptions of newly identified species.
One of the greatest challenges faced by William Clark and Meriwether Lewis on their 1804?6 Corps of Discovery expedition was that of medical emergencies on the trail. Without an attending physician, even routine ailments and injuries could have tragic consequences for the expedition?s success and the safety of its members. Of these dangers, the most insidious and potentially devastating was the slow, painful, and oftentimes fatal ravage of venereal disease. ø Physician Thomas P. Lowry delves into the world of nineteenth-century medicine, uncovering the expedition?s very real fear of venereal disease. Lewis and Clark knew they were unlikely to prevent their men from forming sexual liaisons o...
For the same reasons that explorers of the early twentieth century strove to reach the poles, and their modern counterparts journey to outer space, most people want to visualize the contours of the human experience - the peaks of adaptive success that led to the expansion of civilization, and the troughs in which human presence ebbed. The Backbone of History defines the emerging field of macrobioarchaeology by gathering skeletal evidence on seven basic indicators of health to assess chronic conditions that affected individuals who lived in the Western Hemisphere from 5000 BC to the late nineteenth century. Signs of biological stress in childhood and of degeneration in joints and in teeth increased in the several millennia before the arrival of Columbus as populations moved into less healthy ecological environments. Thus, pre-Colombian Native Americans were among the healthiest and the least healthy groups to live in the Western Hemisphere before the twentieth century.
IBSS is the essential tool for librarians, university departments, research institutions and any public or private institution whose work requires access to up-to-date and comprehensive knowledge of the social sciences.
Drawn from a 2005 international symposium, these essays explore current tyrannosaurid current research and discoveries regarding Tyrannosaurus rex. The opening of an exhibit focused on “Jane,” a beautifully preserved tyrannosaur collected by the Burpee Museum of Natural History, was the occasion for an international symposium on tyrannosaur paleobiology. This volume, drawn from the symposium, includes studies of the tyrannosaurids Chingkankousaurus fragilis and “Sir William” and the generic status of Nanotyrannus; theropod teeth, pedal proportions, brain size, and craniocervical function; soft tissue reconstruction, including that of “Jane”; paleopathology and tyrannosaurid claws...
