Book Description
Who among us hasn’t marveled at the diversity and beauty of shells? Or picked one up, held it to our ear, and then gazed in wonder at its shape and hue? Many a lifelong shell collector has cut teeth (and toes) on the beaches of the Jersey Shore, the Outer Banks, or the coasts of Sanibel Island. Some have even dived to the depths of the ocean. But most of us are not familiar with the biological origin of shells, their role in explaining evolutionary history, and the incredible variety of forms in which they come. Shells are the external skeletons of mollusks, an ancient and diverse phylum of invertebrates that are in the earliest fossil record of multicellular life over 500 million years ago. There are over 100,000 kinds of recorded mollusks, and some estimate that there are over amillion more that have yet to be discovered. Some breathe air, others live in fresh water, but most live in the ocean. They range in size from a grain of sand to a beach ball and in weight from a few grams to several hundred pounds. And in this lavishly illustrated volume, they finally get their full due. The Book of Shells offers a visually stunning and scientifically engaging guide to six hundred of the most intriguing mollusk shells, each chosen to convey the range of shapes and sizes that occur across a range of species. Each shell is reproduced here at its actual size, in full color, and is accompanied by an explanation of the shell’s range, distribution, abundance, habitat, and operculum—the piece that protects the mollusk when it’s in the shell. Brief scientific and historical accounts of each shell and related species include fun-filled facts and anecdotes that broaden its portrait. The Matchless Cone, for instance, or Conus cedonulli, was one of the rarest shells collected during the eighteenth century. So much so, in fact, that a specimen in 1796 was sold for more than six times as much as a painting by Vermeer at the same auction. But since the advent of scuba diving, this shell has become far more accessible to collectors—though not without certain risks. Some species of Conus produce venom that has caused more than thirty known human deaths. The Zebra Nerite, the Heart Cockle, the Indian Babylon, the Junonia, the Atlantic Thorny Oyster—shells from habitats spanning the poles and the tropics, from the highest mountains to the ocean’s deepest recesses, are all on display in this definitive work.

Book Description
"This new edition reflects many of the very significant advances which have taken place in the period since the last edition was published. I am confident that you will feel that this is a worthy addition to your asphalt book shelf." Robert Hunter This respected Handbook has earned its reputation as the authoritative source of information on bitumens used in road pavements and other surfacing applications. This new edition has been up-dated to ensure The Shell Bitumen Handbook retains its excellent reputation. This comprehensive Handbook covers every aspect of bitumen, from its manufacture, storage and handling to specifications and quality along with a whole chapter on bitumen emulsions. The mechanical testing and physical properties of bitumen, its structure and rheology, properties such as durability and adhesion, and the influence of these properties on performance in practice are all set out in individual chapters. A further chapter is devoted to the practice of enhancing the performance of bitumen's by the addition of modifiers. Considerable attention is given to the different aspects of asphalts, detailing types of mixture, their manufacture and testing, mechanical properties, transport, laying and compaction and mixture design. This excellent reference also devotes chapters to the important topics of analytical design of flexible pavements and the technology of surface dressing. Since the last edition, there have been significant strides in a number of key areas of asphalt technology. These include the development of new mixtures, an improved understanding of the mechanisms by which pavements fail and the availability of high-performance bitumens. The Handbook has been fully revised to reflect these advances, as well as updating the standard procedures and methods which are necessary nowadays for those involved in using asphalts in an environment of ever-more demanding specifications. Compiled by the Shell Bitumen European Technical Team The Shell Bitumen Handbook is intended to be of daily use to civil engineers in pavement construction and maintenance, and also to students and researchers.

Book Description
All you need to know to log and classify the shells in your collection. Hints, tips and expert advice to help you get started. Over 150 photographs and illustrations make it easy to identify your finds in the field: Gastropods, bivalves, cephalopods and scaphopods. This practical identification guide covers a wide range of shells from all parts of the world. The book combines comprehensive and informative text with color illustrations, focusing on the shells themselves rather than on the marine creatures that once inhabited them. An introductory section covers mollusks and their classification, terminology and collection, along with conservation issues and an invaluable identification key. The main section is the identification guide to species in precise detail and clarity. The description of each species is accompanied on the same page with an easy-to-use identification key and color illustration.

Book Description
From “one of the master naturalists of our time” (American Scientist), a fascinating exploration of what seashells reveal about biology, evolution, and the history of life Geerat Vermeij wrote this “celebration of shells” to share his enthusiasm for these supremely elegant creations and what they can teach us about nature. Most popular books on shells emphasize the identification of species, but Vermeij uses shells as a way to explore major ideas in biology. How are shells built? How do they work? And how did they evolve? With lucidity and charm, the MacArthur-winning evolutionary biologist reveals how shells give us insights into the lives of animals today and in the distant geological past.
