"Amber is a semi-precious gem that is formed over eons by natural forces out of the resin of trees. Human fascination with amber dates back to prehistoric times, when it was probably considered to have magical powers and was used for adornment and trade. Amber amulets and beads dating from 35,000 to 1,800 B.C. have been found, and where they have been found (for example in graves hundreds of miles from their chemically determined origins) has often helped to establish ancient trade routes." "The preservative qualities of plant resins were well known by the ancients. The Egyptians used resins to embalm their dead, and the Greeks used them to preserve their wine. Amber often preserved fossils, frequently in a pristine state, of all kinds of animal and plant organisms that made contact with the sticky substance and became trapped in it. These fossils include such fragile organisms as nematodes and mushrooms that ordinarily are not preserved under normal processes of fossilization, as well as larger organisms like scorpions and lizards, and the fossils are preserved in their full three-dimensional form, complete with minute details of scales, mouth parts, antennae, and hairs. It has even been suggested that viable DNA may persist in some amber-trapped organisms." "This book is a compendium of all that we know about life found in amber. It surveys all life forms, from microbes to vertebrates and plants, that have been reported from amber deposits throughout the world, beginning with the earliest pieces dating from some 300 million years ago. It also describes the formation of amber and the location, geological history, and early exploration of the major world amber deposits, including those still being worked today." "The book also provides practical information on how to determine fake amber containing present-day forms of life. It can serve as a beginning for tracing the geological history of a particular group of animals or plants or even reconstructing ancient paleoenvironments, and because amber fossils are preserved so completely, in a transparent medium, they can be intimately compared with related living species. Finally, the book discusses what amber fossils can tell us about evolution and speciation, cellular preservation, and paleosymbiosis." "The book is illustrated with 37 color photographs, 154 black-and-white photographs and drawings, and 8 maps."--BOOK JACKET.Title Summary field provided by Blackwell North America, Inc.

The Poinars are world leaders in the study of amber fossils and have spent years examining the uniquely rich supply that has survived from the ancient forests of the Dominican Republic. They draw on their research here to reconstruct in words, drawings, and spectacular color photographs the ecosystem that existed on the island of Hispaniola between fifteen and forty-five million years ago. The Poinars present richly detailed drawings of how the forests once appeared. They discuss how and when life colonized Hispaniola and what caused some forms to become extinct. Along the way, they describe how amber is formed, how and where it has been preserved, and how it is mined, sold, and occasionally forged for profit today.

The fossilized resin of ancient trees, amber preserves organic material--most commonly insects and other invertebrates--and with it the shape and surface detail that are usually obliterated or hopelessly distorted during the mineralization we associate with fossils. This fascinating substance offers a unique intersection of the fields of paleontology, botany, entomology, and mineralogy.

SPIRAL INTO WAR! The Helix: a vast spiral of ten thousand worlds turning around its sun. Aeons ago, the enigmatic Builders constructed the Helix as a refuge for alien races on the verge of extinction. Two hundred years ago, humankind came to the Helix aboard a great colony ship, and the builders conferred on them the mantle of peacekeepers. For that long, peace has reigned on the Helix. But when shuttle pilot Jeff Ellis crash-lands on the world of Phandra, he interrupts a barbarous invasion from the neighbouring Sporelli, who are now racing to catch and exterminate Ellis before he can return to New Earth and inform the peacekeepers. Eric Brown returns to the rich worlds he created in the best-selling Helix with a vast science-fiction adventure populated with strange characters and fascinating creatures.
