Gemstones have been a source of fascination for Millenia, from the icy brilliance of diamond and the soft iridescence of pearl, to the deep red garnets treasured by ancient Egyptians and Victorians alike. They are used for their natural beauty in jewellery, worn for protection as talismans, associated with romance and power. They are also of scientific importance, forming over billions of years and containing secrets to the inner earth. This book examines the world's most commonly encountered gemstones, exploring their unique beauty, rarity, and durability. It reveals how these gem materials formed, where they are mined, how they are identified by their physical and optical properties, their enhancements and imitations. Travelling through each gem's history and use in adornment, it is filled with fascinating facts for the curious to the professional. With sumptuous colour photographs, Gemstones is a dazzling insight into the world of the rare and valuable.

This is the story of the dinosaurs, uniquely retold through 50 of the most significant findings from the fossil record. Each entry is illustrated with special photography of original specimens that illustrate both the history of dinosaur discovery and key evolutionary events. Palaeontologist Paul M. Barrett explains the importance of each fossil and how it marks a crucial inflection point in an evolutionary dynasty that ruled the Earth for more than 150 million years. The book is divided into themed sections, beginning with dinosaur ancestors before introducing all the major dinosaur groups and moving on to the distinctive aspects of their biology such as feeding, distribution, locomotion and behaviour. The final section focuses on the first fossil birds including the legendary Archaeopteryx, the feathered dinosaur that is widely considered to be the first bird species.

An illustrated guide to introduction to major fossil groups.

Amber is a remarkable substance that originates from the resin of trees that lived millions of years ago. Anything that became trapped in this sticky resin was fossilized and perfectly preserved. The insects and other inclusions found in amber today are providing scientists with unique insights into the history of life on Earth. In this new edition of "Amber", Andrew Ross provides an engaging overview of this prehistoric substance and its fossilized inclusions. The book explains how amber is formed, where it is found and how to distinguish genuine amber from fakes. It describes its many uses, both in art and science, and recounts the elusive search for DNA from fossilized insects. Detailed keys and stunning photographs, including previously unseen pieces of Burmese amber from the Museum's collections, guide the reader in the identification of species of insects and other amber inclusions. "Amber" is essential reading for all those with an interest in this natural time capsule.
