The chapters in this book will cover the paleontology and geology
of some important rock formations (Paleozoic and Paleogene) in the
northeastern United States. The emphasis will be on brachiopod
paleontology, specifically taxonomy, but will also include comments
on morphologic variation and community analysis. The Martinsburg
formation in the lower mid-Hudson Valley has been studied for many
years but recently yielded numerous marine fossils that shed new
light on the community ecology of the formation in the region. The
Middle Silurian Shawangunk Formation near New Paltz, New York, is
an important ridge-maker that extends toward the southwest into
Pennsylvania. Recently discovered rare trace fossils in the
Shawangunk will be discussed along with the depositional
environment of the conglomerate. The Onondaga Limestone is a
well-known formation that crops out from Port Jervis, northeast
toward Albany and the westward to Buffalo. The brachiopods and
community structure of the formation will be covered in some
detail. The paleoecology of the Paleogene Hornerstown Formation of
New Jersey will also be discussed, including a biostrome of large
terebratulid brachiopods.
Carbonate sediments are of increasing relevance for archives of
past environmental conditions and for economical reasons in areas
of geothermal energy and hydrocarbon reservoirs. Complex
interaction of physical and chemical parameters with biological
parameters determines the architecture and composition of carbonate
sedimentary bodies. This book closes some of the still existing
gaps in our understanding of the influence and interplay of
physical, chemical, and biological parameters with carbonate
sedimentation. An understanding of this interaction is not only
required for reliable prediction of reservoir quality but also for
a robust interpretation of environmental conditions in the past and
the present. It is written by geologists for geologists in order to
provide an easily accessible overview of the large amount of
relevant information provided by the neighbouring sciences. The
approach of the book is to document the modern depositional
environments of three classical areas of carbonate deposition, each
characteristic for a specific sedimentological setting (isolated
platform, attached shelf, ramp) in order to assess both the range
of physical, biological and chemical parameters and their
sedimentary response. This book presents a comprehensive
compilation based on data from published work and unpublished
theses, and the integration of these data in order to extract
previously undiscovered relationships between the discussed
parameters and carbonate deposition.
The vertebrate integument arose about 450 million years ago as
an armour of dermal bony plates in small, jawless fish-like
creatures, informally known as the ostracoderms. This book reviews
the major changes that have occurred in the vertebrate integument
from its beginnings to the present day. Critical questions
concerning the origin, structure and functional biology of the bony
integument are discussed and intrinsically linked to major steps in
vertebrate evolution and phylogeny the origin of jaws and the
origin of teeth. The discussions include the origins of
mineralization of major vertebrate skeletal components such as the
dermatocranium, branchial arches and vertebral column. The advances
that led to the origin of modern fishes and their phylogenetic
development are reviewed and include the evolution of fins and
replacement of the bony plates with several types of dermal scales.
The evolution of reptiles saw a major transformation of the
integument, with the epidermis becoming the protective outermost
layer, from which the scales arose, while the dermis lay below
it.The biological significance of the newly-evolved -keratin in
reptilian scales, among the toughest natural materials known, is
discussed in the context of its major contribution to the great
success of reptiles and to the evolution of feathers and avian
flight. The dermis in many vertebrates is strengthened by layers of
oppositely oriented cross-fibres, now firmly entrenched as a design
principle of biomechanics. Throughout the book conventional ideas
are discussed and a number of new hypotheses are presented in light
of the latest developments. The long evolutionary history of
vertebrates indicates that the significance of the Darwinian
concept of survival of the fittest may be overstated, including in
our own mammalian origins and that chance often plays a major role
in evolutionary patterns. Extensive illustrations are included to
support the verbal descriptions.

>The rich fossil record of the Atlantic and Gulf coastal plains
of the United States is a gold mine for interested scientists. The
last thirty million years of Earth history are superbly chronicled
by a succession of fossil assemblages extending from the St.
Lawrence River to Florida. Marine scientists, paleontologists, and
systematic biologists alike need a thorough guide to interpret this
history. Cenozoic Seas: The View from Eastern North America
analyzes the changing geography, the arrival and departures of
ecosystems and species, and the affect of climate on living things.
The author classifies all of the region's fossil-bearing formations
and their contents within a logical, descriptive framework of space
and time, providing a clear path for those studying evolution and
extinction within specific communities of organisms. The book is
also an excellent field guide for fossil collectors, providing
detailed information for all species illustrated. Many organisms
have never before been illustrated in a book on fossil shells.
From The Land Before Time to Jurassic Park, images of fantastically
large, long-necked, plant-eating dinosaurs have captured our
imaginations. These are the sauropods: centerpieces of museums and
gentle giants of the distant past. Imagine what it must have been
like to crest a hill and see in the valley below not just one
sauropod, but an entire herd, feeding its way across the landscape.
The most massive land animals ever to have lived, sauropods roamed
widely across the continents through most of the "Age of Dinosaurs"
from about 220 to 65 million years ago. They reached incredible
sizes, giving rise to the question: Why were they so big? Early
guesses suggested that they gained protection from predators by
virtue of their size, which also allowed them to reach the tops of
trees in order to eat leaves and conifer needles. More recent
hypotheses hold that they needed a long and complicated digestive
tract due to their consumption of low-nutrient food sources: size
was an offshoot of that need. Whatever the explanation, there is
little doubt that natural selection produced something
extraordinary when the Sauropoda diversified into a wide variety of
species. This book combines majestic artwork and the best of
paleontological research to resurrect the lives of sauropods. The
Sauropod Dinosaurs shows how these amazing creatures raised and
defended their young, traveled in groups, and interacted with the
rich diversity of Mesozoic plants and animals. Beautiful enough to
sit on the coffee table, the book also serves as the best reference
available on these bygone giants. Anyone with a passion for
dinosaurs or prehistoric life will cherish this
once-in-a-generation masterpiece. The book includes the following
features:* Over 200 full-color illustrations* More than 100 color
photographs from museums, field sites, and collections around the
world* Thoughtfully placed drawings and charts* Clearly written
text reviewed by major sauropod researchers* Descriptions of the
latest sauropod concepts and discoveries* A field guide to major
groups of sauropods* Detailed skeletal reconstructions and
anatomical restorations* A comprehensive glossary
This detailed exposition gives background and context to how modern
biogeography has got to where it is now. For biogeographers and
other researchers interested in biodiversity and the evolution of
life on islands, Biogeology: Evolution in a Changing Landscape
provides an overview of a large swathe of the globe encompassing
Wallacea and the western Pacific. The book contains the full text
of the original article explored in each chapter, presented as it
appeared on publication. Key features: Holistic treatment,
collecting together a series of important biogeographical papers
into a single volume Authored by an expert who has spent nearly
three decades actively involved in biogeography Describes and
interprets a region of exceptional biodiversity and extreme
endemism The only book to provide an integrated treatment of
Wallacea, Melanesia, New Zealand, the New Zealand Subantarctic
Islands and Antarctica Offers a critique of fashionable
neo-dispersalist arguments, showing how these still suffer from the
same weaknesses of the original Darwinian formulation. The chapters
also include analysis of many major theoretical and philosophical
issues of modern biogeographic theory, so that those interested in
a more philosophical approach will find the book stimulating and
thought-provoking.
"Peking Man," a cave man once thought a great hunter who had first tamed fire, was actually a composite of the gnawed remains of some fifty women, children, and men unfortunate enough to have been the prey of the giant cave hyena. Researching the famous fossil site of Dragon Bone Hill in China, scientists Noel T. Boaz and Russell L. Ciochon retell the story of the cave's unique species of early human, Homo erectus. Boaz and Ciochon take readers on a gripping scientific odyssey. New evidence shows that Homo erectus was an opportunist who rode a tide of environmental change out Africa and into Eurasia, puddle-jumping from one gene pool to the next. Armed with a shaky hold on fire and some sharp rocks, Homo erectus incredibly survived for over 1.5 million years, much longer than our own species Homo sapiens has been on Earth. Tell-tale marks on fossil bones show that the lives of these early humans were brutal, ruled by hunger and who could strike the hardest blow, yet there are fleeting glimpses of human compassion as well. The small brain of Homo erectus and its strangely unchanging culture indicate that the species could not talk. Part of that primitive culture included ritualized aggression, to which the extremely thick skulls of Homo erectus bear mute witness. Both a vivid recreation of the unimagined way of life of a prehistoric species, so similar yet so unlike us, and a fascinating exposition of how modern multidisciplinary research can test hypotheses in human evolution, Dragon Bone Hill is science writing at its best.
Receptaculitids are extinct high-level fossils that provide a
window into the history of life. After the discovery and analysis
of a deposit of phosphatized receptaculitids on the Baltic Sea
island of Oland, the authors conclude that receptaculitids possess
an attribute not found in any other group of organisms, living or
fossil."
Made in Africa: Hominin Explorations and the Australian Skeletal
Evidence describes and documents the largest collection of modern
human remains in the world from its time period. These Australian
fossils, which represent modern humans at the end of their great
20,000 km journey from Africa, may be reburied in the next two
years at the request of the Aboriginal community. Part one of the
book provides an overview of modern humans, their ancestors, and
their journeys, explores the construct of human evolution over the
last two and half million years, and defines the background to the
first hominins and later modern humans to leave Africa, cross the
world and meet other archaic peoples who had also travelled and
undergone similar evolutionary pathways. Part two focuses on
Australia and the evidence for its earliest people. The Willandra
Lakes fossils represent the earliest arrivals and are the largest
and most diverse late Pleistocene collection from this part of the
world. Although twenty to twenty-five thousand years younger than
the oldest archaeological site in Australia, they exemplify the
migrating end-point of the human story that reflect a diversity and
culture not recorded elsewhere in the world. Part three records the
Willandra Lake Collection itself from a photographic and
descriptive perspective. Evolutionary biologists and geneticists
will find this book to be a valuable documentation of the 20,000 km
hominid migration from Africa to the most distant parts of the
world, and of the challenges and findings of the Willandra Lake
Collection.
