Vertebrate evolution has led to the convergent appearance of many groups of originally terrestrial animals that now live in the sea. Among these groups are familiar mammals like whales, dolphins, and seals. There are also reptilian lineages (like plesiosaurs, ichthyosaurs, mosasaurs, thalattosaurs, and others) that have become sea creatures. Most of these marine reptiles, often wrongly called "dinosaurs", are extinct. This edited book is devoted to these extinct groups of marine reptiles. These reptilian analogs represent useful models of the myriad adaptations that permit tetrapods to live in the ocean. - First book in more than 80 years devoted exclusively to fossil marine reptiles - Documents the most current research on extinct marine reptiles - Prepared by the world's most prominent experts in the field - Well illustrated
Together with a list of auxiliary and cooperating societies, their officers, and other data.
The Congressional Record is the official record of the proceedings and debates of the United States Congress. It is published daily when Congress is in session. The Congressional Record began publication in 1873. Debates for sessions prior to 1873 are recorded in The Debates and Proceedings in the Congress of the United States (1789-1824), the Register of Debates in Congress (1824-1837), and the Congressional Globe (1833-1873)
In the late eighteenth and early nineteenth centuries, scientists reconstructed the immensely long history of the earth—and the relatively recent arrival of human life. The geologists of the period, many of whom were devout believers, agreed about this vast timescale. But despite this apparent harmony between geology and Genesis, these scientists still debated a great many questions: Had the earth cooled from its origin as a fiery ball in space, or had it always been the same kind of place as it is now? Was prehuman life marked by mass extinctions, or had fauna and flora changed slowly over time? The first detailed account of the reconstruction of prehuman geohistory, Martin J. S. Rudwickâ...
The meat-eating dinosaurs, or Theropoda, include some of the fiercest predators that ever lived. Some of the group's members survive to this day—as birds. The theropod/bird connection has been explored in several recent works, but this book presents 17 papers on a variety of other topics. It is organized into three parts. Part I explores morphological details that are important for understanding theropod systematics. Part II focuses on specific regions of theropod anatomy and biomechanics. Part III examines various lines of evidence that reveal something about theropods as living creatures. The contributors are Ronan Allain, Rinchen Barsbold, Kenneth Carpenter, Karen Cloward, Rodolfo A. Co...
Is it a strange mammal related to the seals, a descendant of a prehistoric reptile, or a new, unidentified animal? Whatever it is, or was, the witnesses call it a sea serpent. Remarkably similar descriptions of a creature with a long body, undulating motion, and horse-sized, snake-like head have left a trail of clues and controversy going back three centuries. In "The Great New England Sea Serpent," J.P. O'Neill draws on the historical record as well as previously unpublished first-hand accounts to chronicle more than 230 sightings of the mysterious marine creatures inhabiting the Gulf of Maine.
Examines the dinosaurs that lived during the Cretaceous period and the climatic and geologic changes that brought about their extinction.
Includes "Dilatory domiciles."
In the 19th and early 20th centuries, North American and European governments generously funded the discoveries of such famous paleontologists and geologists as Henry de la Beche, William Buckland, Richard Owen, Thomas Hawkins, Edward Drinker Cope, O. C. Marsh, and Charles W. Gilmore. In Patrons of Paleontology, Jane Davidson explores the motivation behind this rush to fund exploration, arguing that eagerness to discover strategic resources like coal deposits was further fueled by patrons who had a genuine passion for paleontology and the fascinating creatures that were being unearthed. These early decades of government support shaped the way the discipline grew, creating practices and enabling discoveries that continue to affect paleontology today.
