A Field Guide to Fossils of Texas is the only definitive guide that presents a collection of the state's most common fossils and also shows the most important, noteworthy, and unusual specimens.

Nothing fills us with a sense of wonder like fossils. What looks at first like a simple rock is in fact a clue that reveals the staggering diversity of ancient environments, the winding pathways of evolution, and the majesty of a vanished earth. But as much as one might daydream of digging a hole in the backyard and finding a Tyrannosaurus, only a few places contain these buried treasures, and when a scientist comes across a remnant of prehistoric life, great care must be taken. What do budding paleontologists need to know before starting their search? In Fantastic Fossils, Donald R. Prothero offers an accessible, entertaining, and richly illustrated guide to the paleontologist's journey. He details the best places to look for fossils, the art of how to find them, and how to classify the major types. Prothero provides expert wisdom about typical fossils that an average person can hope to collect and how to hunt fossils responsibly and ethically. He also explores the lessons that both common and rarer discoveries offer about paleontology and its history, as well as what fossils can tell us about past climates and present climate change. Captivating illustrations by the paleoartist Mary Persis Williams bring to life hundreds of important specimens. Offering valuable lessons for armchair enthusiasts and paleontology students alike, Fantastic Fossils is an essential companion for all readers who have ever dreamed of going in search of traces of a lost world.

Precious stones, gems and crystals have been valued throughout history not only for their rarity and expense, but for their mystical properties too. Garnet is rumoured to stimulate the heart, while the pearl offers the protection of the goddess Diana – coral, so-called 'witch-stone', is said to guard against the evil eye, and amethyst is said to prevent drunkenness. Gem Magic guides the reader through the uses of and stories surrounding a cornucopia of stones. Introducing the inherent properties of dazzling selection of gems, gemologist Raymond Walters describes how each stone is formed and its key properties, what beliefs have been associated with them through history and around the world, and both their scientific and occult uses. Famous stones, both real and mythical, are lyrically described – from the infamous Koh-i-Noor diamond to unicorn horn and bezoar.

A sweeping account of civilization's complete dependence on copper that "is the best sort of journalism: beautifully written, rich in detail, and impossible to ignore" (Sebastian Junger).

For most of recorded history, copper has proven invaluable: not only did the ancient Romans build their empire on mining copper but Christopher Columbus protected his ships from rot by lining their hulls with it. Today, this pliable and sturdy metal can be found in every house, car, airplane, cell phone, computer, and home appliance across the globe. Yet the history of copper extraction and our present relationship with the metal are fraught with profound difficulties. Copper mining causes irrevocable damage to the Earth, and the mines themselves have significant effects on the economies and wellbeing of the communities where they are located.

Starting in his own backyard in the old mining town of Bisbee, Arizona--where he discovers that the dirt in his garden contains double the acceptable level of arsenic--Bill Carter follows the story of copper to the controversial Grasberg copper mine in Indonesia; to the "ring" at the London Metal Exchange, where a select group of traders buy and sell enormous amounts of the metal; and to an Alaskan salmon run threatened by mining. Page by page, Carter blends the personal and the international in a narrative that helps us understand the paradoxical relationship we have with copper, and the result is a work of first-rate journalism that fascinates on every level.

This valuable book provides information on fossils, fossil collecting, and price ranges for most specimens illustrated. The comprehensive text begins with the earliest fossil record of life from strata representative of "deep time," called the Precambrian by geologists. Foremost in this early record of life are stromatolites, structures formed by very primitive photosynthetic life forms. Attractive, color photographs illustrate this highly informative section of the book. Also discussed and illustrated are various problematic fossil-like objects found in very ancient rock strata and the different ways in which they have been interpreted. Paleontological puzzles, such as latest Precambrian vendozoans, are covered as well. Other chapters feature fossils of the Cambrian Period, when animal life became obvious. Fascinating color photographs show trilobites (prehistoric creatures second only to dinosaurs in popularity), plus other Cambrian fossils. Includes helpful glossary of terms.

'Astounding ... To call this a "history" does not do justice to Helen Gordon's ambition' Simon Ings, Daily Telegraph 'Awe-inspiring ... She has imbued geological tales with a beauty and humanity' Shaoni Bhattacharya-Woodward, Mail on Sunday The story of the Earth is written into our landscape: it's there in the curves of hills, the colours of stone, surprising eruptions of vegetation. Wanting a fresh perspective on her own life, the writer Helen Gordon set out to read that epic narrative. Her odyssey takes her from the secret fossils of London to the 3-billion-year-old rocks of the Scottish Highlands, and from a state-of-the-art earthquake monitoring system in California to one of the world's most dangerous volcanic complexes in Naples. At every step, she finds that the apparently solid ground beneath our feet isn't quite as it seems.

The first field guide that allows amateur rock enthusiasts to identify basic rocks and rock formations in a systematic way Many of us are fascinated by rocks-but identifying them can seem daunting. It's often tricky even for geologists, who rely on experience, intuition, and in-depth familiarity with rock-forming components. Rocks and Rock Formations allows everyone, amateur or professional, to successfully distinguish these amazing masses of minerals, using only careful observation, a magnifying glass, a pocket knife-and a bit of patience. Jurg Meyer provides a structured approach to the identification of all rocks within the three groups: sedimentary, igneous, and metamorphic. Bringing together more than 530 diagrams and photographs to illustrate essential characteristics, Meyer highlights some basics on rocks-their mineral constituents, structures, textures, fossils, weathering patterns, and more-which are important for a determination. The main part of the book is a handy and thorough identification key, which takes into account all possible rock variations, mixtures, and structural differences. The concluding section of the guide delves into rock systematics. Assuming little prior experience or knowledge, Rocks and Rock Formations is an invaluable resource for rock enthusiasts everywhere. Suitable for beginners and amateurs Helpful, systematic identification key Exploration of all types of rocks More than 530 diagrams and photographs

Startling new fossil finds are the lifeblood of modern palaeobiology. Giant sauropod dinosaur skeletons from Patagonia, dinosaurs with feathers from China, and even a tiny dinosaur tail in Burmese amber complete down to every detail of its filament-like feathers, skin, bones and mummified tail muscles inspire awe in a global audience enthralled by the idea of these great creatures walking the earth. Dinosaurs are of perennial interest to all ages, as illustrated by the huge range of dino-themed films, books and live attractions, from the enduring popularity of the Jurassic Park franchise to the success of London s immersive Dinosaurs in the Wild experience.

In the past twenty years, dinosaur study has changed from natural history to testable science. New technologies have revealed secrets locked in the bones in a way nobody predicted we can now work out the colour of dinosaurs, their bite forces, speeds and parental care as well as how they came to die out.This groundbreaking book illustrates how science has replaced speculation and how our understanding of dinosaurs and their world hascompletely changed. The subject has never been so vigorous, has never changed so fast, and has never been so attractive to so many.
