Der achte internationale Geologen-Kongress (Paris 1900) hat die Herausgabe eines Werkes beschlossen, dessen Hauptwert in der Wiederverf.f-fentlichung der Originale der fossilen Arten liegen soll- unter besonderer Berücksichtigung zunächst der alteren Formen u. derjenigen, deren Auffindung in der Litteratur mit Schwierigkeiten verknüpft ist. - Eine aus Vertretern der verschiedenen Lander zusammengesetzte Com-mission wurde mit der Aufgabe betraut, das Programm des Werkes zu entwerfen. Danach soll jede Art auf einem besonderen Blatt erscheinen und zwar:
1. Mit Wiedergabe ded ursprünglichen Original-Abbildung;
2. Mit ded Photographie ded Originals selbst;
3. Mit ded Wiederver.-iffentli-chung der vollständigen Diagnose und
Le dernier Congrès Géolo-gique International (Paris 1900) a adopté en principe la fondation d'une publication pa- : léontologique dont le but est de reediter les types des espèces fossiles, en s’attachant de pré-férence aux formes anciennes et à celles dont la recherche biblio-graphique est difficile. - Une Commission internationale a été chargéed’élaborerle programme de cette publication. Il a été décidé que chaque espèce serait publiée sur flehe afin de per-mettre Tadoption de différents modes de classement. <...>
The present work was carried out in partial fulfillment of the requirements for the degree of Doctor ol Philosophy at the University of Cincinnati. The author Blends his sincere thanks to the members of the Departments of Biological Sciences and Geology at the University fur generously giving of their time and knowledge during the preparation of the manuscript. Especial thanks is extended to Dr. К. Е. Caster, under whose direction the manuscript was prepared. I le was a source ol help and en-tonragement, and his invaluable library made many rare «inks readily available to me. 1 am indebted to Dr. Norman П. Newell for reviewing the manuscript and offering many helpful suggestions. To my "wife continuing thanks for proofreading and typing the greater bulk of the manu-Mtipt.
Earthquakes are one of the greatest natural hazards humans face. During the twentieth century alone, over two million people died during strong ground shaking, attendant fires, tsunamis and landslides. Most recently, in May 2008, about 80 000 people died in an earthquake in Sichuan Province in China and, earlier, on 26 December 2004, more than 200 000 people lost their lives to the tsunami resulting from the great earthquake off the west coast of Sumatra in Indonesia. In December 2003, the ancient city of Bam in Iran was destroyed by an earthquake, with the loss of over 30 000 lives. The worst disaster in modern times occurred in China in July 1976, when an entire city was destroyed and over 240 000 people killed in less than six minutes. Earlier, in 1556, an earthquake in north-central China killed an estimated 800 000 people, one of the worst natural disasters in recorded history. <...>
Zehn Jahre nach der drillen wird hier die vierte undvom Autor hcr gcschen - lctztc Aunagc des I'al;;ontologü;chen Wörtcrbuchs vorgelegt.

Humans are by nature curious, and we are all interested in the Earth on which we live and how various aspects have changed through geologic time. We speculate about what the Earth looked like when there were no trees, when there were no fl owering plants, and when the continental land masses were in different positions than they are today.
Earth is a constantly changing dynamic entity, composed of multiple complex physical, chemical, and biological systems that interact on a spectrum of time and spatial scales. To comprehend the Earth System as a whole, we must understand the nature of these complex subsystems, both now and in the past, and identify the important linkages among them. Earth is now experiencing many changes, some large and more rapid than others.
Paleomagnetic data are useful in many applications in Earth Science from determining paleocurrent directions to analyzing the long-term behavior of the geomagnetic field. Despite the diversity of applications, the techniques required to obtain and analyze the data are similar. This book attempts to draw together the various principles and practices within paleomagnetism in a consistent and up-to-date manner. It was written for several categories of readers: 1) for Earth Scientists who use paleomagnetic data in their' research, 2) for students taking a class with paleomagnetic content, and 3) for other professionals with an interest in paleomagnetic data. <...>
This book is the sequel to Palaeomagnetism and Plate Tectonics written by Michael W. McElhinny, first published in 1973. The aim of that book was to explain the intricacies of paleomagnetism and of plate tectonics and then to demonstrate that paleomagnetism confirmed the validity of the new paradigm. Today it is no longer necessary to explain plate tectonics, but paleomagnetism has progressed rapidly over the past 25 years. Furthermore, magnetic anomaly data over most of the oceans have been analyzed in the context of sea-floor spreading and reversals of the Earth's magnetic field. Oceanic data can also be used to determine paleomagnetic poles by combining disparate types of data, from deep-sea cores, seamounts, and magnetic anomalies. Our aim here is to explain paleomagnetism and its contribution in both the continental and the oceanic environment, following the general outline of the initial book. We demonstrate the use of paleomagnetism in determining the evolution of the Earth's crust. <...>
