Step-by-step Q&As with detailed colour photographs for easy
identification. The Firefly Guide to Minerals, Rocks & Gems is
designed for easy and reliable identification of minerals, gems and
rocks. Beginning with the stone's colour and any streak, and using
a sequence of straightforward questions and answers - aided by
1,300 photographs and drawings - it's easy to narrow down the
possibilities among 350 minerals, gems and rocks to the conclusive
classification. The book organizes the rocks by colour: Blue, Red,
Yellow, Brown, Green, Black, and White. Identification begins with
noting the colour of the rock's streak (i.e., vein, line).
Identification is then further narrowed down with respect to
Colour, Crystal form, Hardness, Lustre, Density, Cleavage, Break
and Tenacity. Each rock's main photograph shows the general or
typical view, and identification tips about features are noted in
the margins of the respective page. Similar stones are presented
for comparison and tips are provided that can eliminate imposters.
Drawings show the mineral's crystal shape. The chemical formula
reveals the elements from which the mineral is composed. There is
also information about where the stone is typically found and some
of the ways that humans have utilized it. Packed with beautiful
photographs of earth's many rocks, minerals and gems, The Firefly
Guide to Minerals, Rocks & Gems is perfect for amateur
mineralogists and collectors.
Unearth the treasures from the prehistoric world beneath your feet.
From glittering ammonites to razor-sharp dinosaur claws and
delicate leaf impressions, uncover our world's primeval past
through the incredible fossils left behind. Arranged into plants
and animals, there are profiles of 50 key fossils, including
well-loved favourites, such as Triceratops, and more curious
remains, such as fossil fish teeth. Learn all about how fossils
form, where they are found, and how ancient animals are
reconstructed. Filled with facts and containing recently discovered
species, this book will help even the biggest fossil fans learn
something new. Stunning photographs can be studied in detail, while

provides a quick overview of all the key species in the book. My
Book of Fossils is an engrossing children's book about fossils and
dinosaurs, and is sure to be a hit with fact-obsessed young
enthusiasts of all things prehistoric.
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.
Studying geology in the field will draw anyone curious about how
our planet works into the field time and time again. Ireland is
endowed with a spectacular variety of geology. The rocks that make
up the island of Ireland offer a unique window into a
2-billion-year history, a history which includes almost all types
of geological settings, including sedimentary basins, shallow
tropical seas, high mountain ranges and active volcanoes. Seventeen
field areas are described, showing how to venture into the field to
explore the classic sites of Irish geology. Most excursions are on
or near the coast and the variety of landscapes reflects the
diversity of geology. Emphasis is placed on understanding processes
that operated in the geological past to produce today's rocks.
Detailed 'step-by-step' itineraries are provided and the material
is presented in a manner accessible to the non-specialist.

Our understanding of the British Palaeolithic and Mesolithic has
changed dramatically over the last three decades, and yet not since
H. J. Fleure's A Natural History of Man in Britain (1951) has the
New Naturalist Library included a volume focused on the study of
early humans and their environment. In this long overdue new book,
distinguished archaeologist Nick Ashton uncovers the most recent
findings, following the remarkable survival and discovery of bones,
stone tools and footprints which allow us to paint a picture of the
first human visitors to this remote peninsula of north-west Europe.
As part of the Ancient Human Occupation of Britain project and
subsequent research, Ashton is involved in an unrivalled
collaborative effort involving archaeologists, palaeontologists,
and earth scientists at different British institutes, including the
Natural History Museum and the British Museum. Using an
interdisciplinary approach, the book explores the latest
discoveries such as footprints at Happisburgh, Norfolk that are
thought to be nearly one million years old, flint artefacts at
Pakefield in Suffolk and mammoth remains at West Runton, among
others. These remarkable remnants help our quest to unravel the
interactions between the changing environments and their ancient
human occupants, as well as their lifestyles and migrations. Early
humans colonised our remote corner of the European mainland time
and again, despite being faced with ice age climates with
far-reaching consequences. Setting the scene on the Norfolk coast
almost a million years ago, Ashton tells the story of the fauna,
flora and developing geography of Britain against the backdrop of
an ever-changing climate. Above all, he explores how early people
began as brief visitors to this wild remote land, but over time
through better ways of acquiring food and developing new
technologies, they began to tame, shape and dominate the
countryside we see today.
Charles Darwin's voyage on the HMS Beagle was a journey that would
revolutionise our understanding of the natural world and our place
in it. The magisterial work it spawned, On the Origin of Species,
is widely associated with the flora and fauna of the Galapagos
Islands. Less well known is Darwin's passion for geology and how
his fossil discoveries in South America - by demonstrating the
relationship between extinct lifeforms and living species - shaped
his theory of evolution. This is the story of those fossil-hunting
adventures in the 1830s, the pioneering science behind the fossils
he found, and how these remarkable discoveries played a crucial
role in forging Darwin's revolutionary ideas.
