Fossil arachnids date back more than 400 million years to the Silurian period, making them one of the first animal groups to appear in terrestrial ecosystems. This book provides information on what the arachnids are and their relationships to one another.

Compared to insects, fossil spiders have received only scant attention in the literature. Previously, the only works available were numerous scientific papers, many published in foreign languages. Most of these are basic descriptive taxonomic works, with very few considering broader biological concepts. Despite a significant increase in the discovery and description of fossil spiders within the last quarter Century this void remained unfilled. Thus, this short monograph aims to achieve several objectives. Firstly, to provide general and up to date background information on the overall importance and diversity of fossils spiders, including an indication of those groups for which the taxonomy is spurious and in need of reassessment. Secondly, to discuss the techniques available for working with fossil spiders and some of the problems encountered by palaeoarachnologists, including bias and limitations of the spider fossil record. Thirdly, the overall evolutionary history of spiders is summarized in the form of an evolutionary tree, which is subsequently used to address key issues of broad interest, such as origins, diversifications and extinctions, including the effects of mass extinctions and predator-prey co-radiations. Finally, the contribution that fossil data can make to understanding the past and present biogeography of the order is considered. This book should be of interest to both amateur and professional arachnologists and palaeontologists and will also serve as a general palaeontological reference work for neonologists studying extant spiders.

The arachnids include some of the planet's most feared creatures, such as venomous scorpions and deadly funnel-web spiders. Other arachnids-like the tiny house dust mites that live by the millions in all of our homes-are among the world's smallest and most successful animals. The Arachnid Class explores the origins, scientific classification, and biology of arachnids, from familiar garden spiders to less common creatures such as wind scorpions and the rare, cave-dwelling "living fossil" spiders of Southeast Asia. The more than 80,000 known species of arachnids play important roles in the world's ecosystems. As The Arachnid Class shows, these creatures also affect human life in a variety of ways. Book jacket.

The Encyclopedia of Paleontology is designed to address the shortage of general reference works on both vertebrate and invertebrate paleontology and to serve the needs of students and lay persons interested in the field. As the encyclopedia aims to provide basic information, the majority of the 350 entries are devoted to explanations of paleontological concepts and techniques, examinations of the evolutionary development of particular organisms and biological features, profiles of major discoveries, and biographies of leading scientists. Each entry includes an essay and a further reading list. An international team of 200 leading experts in the field has prepared the illustrations and the essays, which range from concise descriptions to comprehensive discussions.
