Mammals from the Age of Dinosaurs
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.
Vertebrate Paleontology in the Neotropics
Because of its unique geographic and temporal position, the La Venta badlands in central Columbia hold special significance for understanding the evolution of vertebrate faunas in South America. John Flynn, Curator of Geology at The Field Museum, and other contributors present detailed information and interpretation about the paleobiology and environment of La Venta animals. Includes taxonomic index.
Textural Observations on Some Living Species of Planktonic Foraminifera
Wall textures of 11 species of spinose and quasi-spinose planktonic foraminifera collected in plankton tows from the North and Equatorial Atlantic have been studied with the scanning electron microscope. Illustrations and descriptions of these textures are given herein. During the ontogeny of the individual the chamber wall thickens and the texture is modified in various forms. Thickening occurs by the addition of sheet-like laminations and clustering of crystallites that generally develop into ridges among the pores. Patterns of textural development vary among species, but there are some common trends.
Stratigraphic Record of the Neogene Globorotalid Radiation (planktonic Foraminiferida)
The histories of lineages forming the Neogene globorotalid radiation in the planktonic foraminifera are reconstructed primarily from stratigraphic distributions. Data on major taxa are synthesized, with particular reference to the development of shell design, and related to biogeograpy and evolutionary strategies.The radiation was established about the base of the lower Miocene by three groups (Fohsella, Globorotalia zealandica lineage, and G. praescitula plexus), which probably arose from separate paragloborotalid lineages.Common trends (size increase, chamber compression, keel development, reduced wall relief) early in the radiation culminated in the evolution of disklike taxa which, since...
Landmarks in Foraminiferal Micropalaeontology
TMS Special Publication 6. This TMS Special Publication comprises a collection of 23 papers with an international authorship reflecting on landmarks in the history and development of Foraminiferal micropalaeontology. The volume is prefaced by an introductory overview that provides a brief and selected historical setting, as well as the intended aims of the book. Selected developments in Foraminiferal studies from a global perspective are presented from the time of Alcide d'Orbigny and the founding of the Paris MNHN collections in the mid-nineteenth century to the use of foraminifera in industry, other museum collections, palaeoceanography and environmental studies, regional studies from the Southern Hemisphere and the rise and fall of significant research schools. The book concludes with a chapter on the modelling of foraminifera. Landmarks in Foraminiferal Micropalaeontology: History and Development will be of particular interest to micropalaeontologists, other Earth scientists, historians of science, museum curators and the general reader with an interest in science.
Predators with Pouches
'Predators With Pouches' deals with the carnivorous marsupial faunas of Australasia and the Americas. Written by experts in each field from all over the world, it provides a synthesis of current knowledge including paleontology, ecology, behavior and conservation.
