The Tuscany habitation site (EgPn-377) located in northwest Calgary
was excavated between 1995 and 1997. The site stratigraphy of the
large depression contained a series of buried paleosols situated
between Mazama tephra above, dating to 6730 +- 40 14C years BP, and
Glacial Lake Calgary sands below, dating to approximately 13,900
calendar years ago. These paleosols comprised the focus of this
volume. One of the research objectives was to examine the site for
spatial information via the processing of bulk sediment samples.
Such samples had the potential to yield information on the
distribution of small-scale archaeological remains throughout the
site. Sediment samples representing 1% volumes were collected from
each excavated level of each unit in the site grid. Through
flotation processing an inventory of bone, lithics, insects, fungal
spores, mollusks and charred macrobotanical remains were recovered.
The charred macrobotanical remains were the focus of this research.
Though the inventory is small, it provides a representative sample
of the remains of plants that grew locally in the depression
through the early Holocene. The charred botanical remains were
compared with pollen and soil studies along with modern vegetation
and climate records to develop a model for open parkland in the
area for the early Holocene. The reconstructed landscape appears to
have provided a habitat for a broad spectrum of fauna along with a
diverse inventory of potentially useful plants for early Holocene
peoples to exploit.
The first English translation of Johannes Weigelt's 1927 classic
makes available the seminal work in taphonomy, the study of how
organisms die, decay, become entombed in sediments, and fossilize
over time. Weigelt emphasized the importance of empirical work and
made extensive observations of modern carcasses on the Texas Gulf
Coast. He applied the results to evidence from the fossil record
and demonstrated that an understanding of the postmortem fate of
modern animals is crucial to making sound inferences about fossil
vertebrate assemblages and their ecological communities. Weigelt
spent sixteen months on the Gulf Coast in the mid-1920s, gathering
evidence from the carcasses of cattle and other animals in the
early stages of preservation. This book reports his observations.
He discusses death and decomposition; classifies various modes of
death (drowning, cold, dehydration, fire, mud, quicksand, oil
slicks, etc.); documents and analyzes the positions of carcasses;
presents detailed data on carcass assemblages at the Smither's Lake
site in Texas; and, in a final chapter, makes comparisons to
carcass assemblages from the geologic past. He raises questions
about whether much of the fossil record is a product of unusual
events and, if so, what the implications are for paleoecological
studies. The English edition of Recent Vertebrate Carcasses
includes a foreword and a translator's note that comment on
Weigelt's life and the significance of his work. The original
bibliography has been brought up to date, and, where necessary,
updated scientific and place names have been added to the text in
brackets. An index of names, places, and subjects is included, and
Weigelt's own photographs of carcasses and drawings of skeletons
illustrate the text.
The aim of the book is to present original and though-provoking
essays in human paleontology and prehistory, which are at the
forefront of human evolutionary research, in honor of Professor
Yoel Rak (a leading scholar in paleoanthropology). The volume
presents a collection of original papers contributed by many of
Yoel's friends and colleagues from all over the globe.
Contributions from experts around the globe fall roughly into three
broad categories: Reflections on some of the broad theoretical
questions of evolution, and especially about human evolution; the
early hominins, with special emphasis on Australopithecus afarensis
and Paranthropus; and the Neanderthals, that contentious group of
our closest extinct relatives. Within and across these categories,
nearly every paper addresses combinations of methodological,
analytical and theoretical questions that are pertinent to the
whole human evolutionary time span. This book will appeal most to
scholars and advanced students in paleoanthropology, human
paleontology and prehistoric archaeology.
One of the leading textbooks in its field, Bringing Fossils to Life
applies paleobiological principles to the fossil record while
detailing the evolutionary history of major plant and animal phyla.
It incorporates current research from biology, ecology, and
population genetics, bridging the gap between purely theoretical
paleobiological textbooks and those that describe only invertebrate
paleobiology and that emphasize cataloguing live organisms instead
of dead objects. For this third edition Donald R. Prothero has
revised the art and research throughout, expanding the coverage of
invertebrates and adding a discussion of new methodologies and a
chapter on the origin and early evolution of life.
As recently as 11,000 years ago--"near time" to
geologists--mammoths, mastodons, gomphotheres, ground sloths, giant
armadillos, native camels and horses, the dire wolf, and many other
large mammals roamed North America. In what has become one of
science's greatest riddles, these large animals vanished in North
and South America around the time humans arrived at the end of the
last great ice age. Part paleontological adventure and part memoir,
"Twilight of the Mammoths "presents in detail internationally
renowned paleoecologist Paul Martin's widely discussed and debated
"overkill" hypothesis to explain these mysterious megafauna
extinctions. Taking us from Rampart Cave in the Grand Canyon, where
he finds himself "chest deep in sloth dung," to other important
fossil sites in Arizona and Chile, Martin's engaging book, written
for a wide audience, uncovers our rich evolutionary legacy and
shows why he has come to believe that the earliest Americans
literally hunted these animals to death.
As he discusses the discoveries that brought him to this
hypothesis, Martin relates many colorful stories and gives a rich
overview of the field of paleontology as well as his own
fascinating career. He explores the ramifications of the overkill
hypothesis for similar extinctions worldwide and examines other
explanations for the extinctions, including climate change.
Martin's visionary thinking about our missing megafauna offers
inspiration and a challenge for today's conservation efforts as he
speculates on what we might do to remedy this situation--both in
our thinking about what is "natural" and in the natural world
itself.
"Fossils are the fragments from which, piece by laborious piece,
the great mosaic of the history of life has been constructed. Here
and there, we can supplement these meager scraps by the use of
biochemical markers or geochemical signatures that add useful
information, but, even with such additional help, our
reconstructions and our models of descent are often tentative. For
the fossil record is, as we have seen, as biased as it is
incomplete. But fragmentary, selective, and biased though it is,
the fossil record, with all its imperfections, is still a treasure.
Though whole chapters are missing, many pages lost, and the
earliest pages so damaged as to be, as yet, virtually unreadable,
this-the greatest biography of all-is one in whose closing pages we
find ourselves."-from Origins In Origins, Frank H. T. Rhodes
explores the origin and evolution of living things, the changing
environments in which they have developed, and the challenges we
now face on an increasingly crowded and polluted planet. Rhodes
argues that the future well-being of our burgeoning population
depends in no small part on our understanding of life's past, its
long and slow development, and its intricate interdependencies.
Rhodes's accessible and extensively illustrated treatment of the
origins narrative describes the nature of the search for
prehistoric life, the significance of geologic time, the origin of
life, the emergence and spread of flora and fauna, the evolution of
primates, and the emergence of modern humans.
