on the most significant orders genera and species in terms of historical turning points such as mass extinctions The book is an accurate and up-to-date collection of the most important paleontological terms and taxa and may be used as a resource by students researchers libraries and museums Though useful to many in professional and academic settings the book is also aimed at general readers of scientific literature who may enjoy the material without a background in paleontology While there are many current resources on the subject few fully encapsulate an accurate representation of the paleontological lexicon This book attempts to compile such a representation in a moderately comprehensive manner and includes a list of the most important monographs and articles that have been consulted to put together this essential workPar Rosalia Gallotti, Margherita Mussi. 2018
This edited volume presents current archaeological research and data from the major early Acheulean sites in East Africa, and addresses…
three main areas of focus; 1) the tempo and mode of technological changes that led to the emergence of the Acheulean in East Africa; 2) new approaches to lithic collections, including lithic technology analyses; and 3) the debated coexistence of the Developed Oldowan and the early Acheulean. The chapters are the proceedings from the workshop titled “The Emergence of the Acheulean in East Africa”, held at University of Rome “La Sapienza” on September 12–13, 2013. The aim of the workshop was to bring together researchers currently working in this field in East Africa, in order to define the characteristics and the evolution of the early Acheulean. The volume was expanded with some chapters on the preceding Oldowan, on the African fauna and on paleovegetation, on the Acheulean in Asia and, eventually, on the Acheulean in Europe. The book is addressed to the scientific community, and will be of interest to researchers, graduate students, archaeologists, paleontologists, and paleoanthropologists. This volume is dedicated to the memory of Jean Chavaillon (March 25, 1925 - December 21, 2013), the leading archaeologist and Quaternary geologist who researched with unfailing enthusiasm the earliest human cultures and directed from 1965 to 1995 the French Archaeological Mission at Melka Kunture.Par Rachel C.

The forbidding Big Badlands in Western South Dakota contain the richest fossil beds in the world. Even today these rocks…
continue to yield new specimens brought to light by snowmelt and rain washing away soft rock deposited on a floodplain long ago. The quality and quantity of the fossils are superb: most of the species to be found there are known from hundreds of specimens. The fossils in the White River Group (and similar deposits in the American west) preserve the entire late Eocene through the middle Oligocene, roughly 35-30 million years ago and more than 30 million years after non-avian dinosaurs became extinct. The fossils provide a detailed record of a period of abrupt global cooling and what happened to creatures who lived through it. The book provides a comprehensive reference to the sediments and fossils of the Big Badlands and will complement, enhance, and in some ways replace the classic 1920 volume by Cleophas C. O'Harra. Because the book focuses on a national treasure, it touches on National Park Service management policies that help protect such significant fossils.Par Gerhard Maier. 2003
From 1907 to 1931 at Tendaguru, a remote site in present-day Tanzania, teams of German (and later British) paleontologists unearthed…
220 tons of fossils, including the bones of a new dinosaur, one of the largest then known. For decades the mounted skeleton of this giant, Brachiosaurus, was the largest skeleton of a land animal on exhibit in the world. The dinosaur and other animal fossils found at Tendaguru form one of the cornerstones of our understanding of life in the Mesozoic era. Visited sporadically during the '30s and '40s, Tendaguru again became the site of scientific interest late in the 20th century. African Dinosaurs Unearthed tells the story of driven scientific adventurers working under difficult conditions and often paying the price with their health--and sometimes with their lives. Set against the background of a troubled century, the book reveals how scientific endeavors were carried on through war and political turmoil, and continue into the present day.Par Scott D. Sampson, Philip J. Currie. 2009
This captivating book, laced with evocative anecdotes from the field, gives the first holistic, up-to-date overview of dinosaurs and their…
world for a wide audience of readers. Situating these fascinating animals in a broad ecological and evolutionary context, leading dinosaur expert Scott D. Sampson fills us in on the exhilarating discoveries of the past twenty-five years, the most active period in the history of dinosaur paleontology, during which more "new" species were named than in all prior history. With these discoveries--and the most recent controversies--in mind, Sampson reconstructs the odyssey of the dinosaurs from their humble origins on the supercontinent Pangaea, to their reign as the largest animals the planet has ever known, and finally to their abrupt demise. Much more than the story of who ate whom way back when, Dinosaur Odyssey places dinosaurs in an expansive web of relationships with other organisms and demonstrates how they provide a powerful lens through which to observe the entire natural world. Addressing topics such as extinction, global warming, and energy flow, Dinosaur Odyssey finds that the dinosaurs' story is, in fact, a major chapter in our own story.Par Jean Guex, Federico Galster, yvind Hammer. 2015
The object of this book is to explain how to create a synthesis of complex biostratigraphic data, and how to…
extract from such a synthesis a relative time scale based exclusively on the fossil content of sedimentary rocks. Such a time scale can be used to attribute relative ages to isolated fossil-bearing samples. The book is composed of 10 chapters together with several appendices. It is a totally revised version of "Biochronological Correlations" published in 1991 and includes various new chapters. The book offers a solution for the theoretical problem of how fossils can be used to make reliable quantitative stratigraphic correlations in sedimentary geology. It also describes the use of highly efficient software along with several examples. The authors compare their theoretical model with 2 other relevant studies: probabilistic stratigraphy and constrained optimization (CONOP).Par Sara Cano, Francesc Gascó. 2018

un viatje al·lucinant a l'era dels dinosaures. Un grup d'amics ha trobat un portal que els permet viatjar a un lloc on no es van extingir els dinosaures. Junts hauran de fer front a un munt de perills, coneixeran de prop els secrets dels dinosaures i viuran grans aventures. En Leo, la Carla, en Dani, l'Elena i en Lucas estaven convençuts que passarien la tarda castigats en un laboratori ple de fòssils. Però els esperava l'aventura més boja de la vida: un viatge en un lloc... on els dinosaures estan vius! Un cop allà han de trobar la manera de tornar al seu món. I de rescatar una persona perduda en aquella terra misteriosa. Però troben unes dents mágiques que els donen uns poders al·lucinants! Encara que, primer de tot, l'equip necessita un nom. Què us sembla...JURÀSSIC TOTAL?Par Aidan Cockburn, Eve Cockcburn, Theodore A. Reyman. 1998
To look upon a mummy is to come face to face with our past. This book presents the story of…
mummification as a practice worldwide. Mummies have been found on every continent, some deliberately preserved by use of a variety of complex techniques (as with the ancient Egyptians), others accidentally by dry baking heat, intense cold and ice, or by tanning in peat bogs. By examining these preserved humans, we can get profound insights into the lives, health, culture and deaths of individuals and populations long gone. The first edition of this book was acclaimed as a classic. This readable new edition builds on these foundations, investigating the fantastic new findings in South America, Europe and the Far East. It will be a must-have volume for anyone working in paleopathology and a fascinating read for all those interested in anthropology, archaeology, and the history of medicine.Par David Johnson, Robert Henderson. 2016
The Geology of Australia provides a vivid and informative account of the evolution of the Australian continent over the last…
4400 million years. Starting with the Precambrian rocks that hold clues to the origins of life and the development of an oxygenated atmosphere, it goes on to cover the warm seas, volcanism and episodes of mountain building, which formed the eastern third of the Australian continent. This illuminating history details the breakup of the supercontinents Rodinia and Gondwana, the times of previous glaciations, the development of climates and landscapes in modern Australia, and the creation of the continental shelves and coastlines. Separate chapters cover the origin of the Great Barrier Reef, the basalts in Eastern Australia, and the geology of the Solar System. This second edition features two new chapters, covering the evolution of life on Earth while emphasising the fossil record in Australia, and providing a geological perspective on climate change. From Uluru to the Great Dividing Range, from earthquakes to dinosaurs, from sapphires to the stars The Geology of Australia is a comprehensive exploration of the timeless forces that have shaped this continent.Par Theresa Schilhab, Frederik Stjernfelt, Terrence Deacon. 2011

2007). In 1997 the American anthropologist Terrence Deacon published The Symbolic Species: The Coevolution of Language and the Brain. The book is widely considered a seminal work in the subject of evolutionary cognition. However, Deacons book was the first step - further steps have had to be taken. The proposed anthology is such an important associate. The contributions are written by a wide variety of scholars each with a unique view on evolutionary cognition and the questions raised by Terrence Deacon - emergence in evolution, the origin of language, the semiotic 'missing link', Peirce's semiotics in evolution and biology, biosemiotics, evolutionary cognition, Baldwinian evolution, the neuroscience of linguistic capacities as well as phylogeny of the homo species, primatology, embodied cognition and knowledge types.Par Theresa Schilhab, Frederik Stjernfelt, Terrence Deacon. 2011

bear in interpreting the fossil record and the book introduces the latest techniques, from multivariate investigations of biogeography and biostratigraphy to engineering analysis of dinosaur skulls, and from homeobox genes to cladistics. All the well-known fossil groups are included, including microfossils and invertebrates, but an important feature is the thorough coverage of plants, vertebrates and trace fossils together with discussion of the origins of both life and the metazoans. All key related subjects are introduced, such as systematics, ecology, evolution and development, stratigraphy and their roles in understanding where life came from and how it evolved and diversified.Unique features of the book are the numerous case studies from current research that lead students to the primary literature, analytical and mathematical explanations and tools, together with associated problem sets and practical schedules for instructors and students."..any serious student of geology who does not pick this book off the shelf will be putting themselves at a huge disadvantage. The material may be complex, but the text is extremely accessible and well organized, and the book ought to be essential reading for palaeontologists at undergraduate, postgraduate and more advanced levels--both in Britain as well as in North America." Falcon-Lang, H., Proc. Geol. Assoc. 2010"...this is an excellent introduction to palaeontology in general. It is well structured, accessibly written and pleasantly informative .....I would recommend this as a standard reference text to all my students without hesitation."

In 1961, while mapping rock exposures along the Colville River in Alaska, an oil company geologist would unknowingly find the…
evidence for a startling discovery. Long before the North Slope of Alaska was being exploited for its petroleum resources it was a place where dinosaurs roamed. Dinosaurs under the Aurora immerses readers in the challenges, stark beauty, and hard-earned rewards of conducting paleontological field work in the Arctic. Roland A. Gangloff recounts the significant discoveries of field and museum research on Arctic dinosaurs, most notably of the last 25 years when the remarkable record of dinosaurs from Alaska was compiled. This research has changed the way we think about dinosaurs and their world. Examining long-standing controversies, such as the end-Cretaceous extinction of dinosaurs and whether dinosaurs were residents or just seasonal visitors to polar latitudes, Gangloff takes readers on a delightful and instructive journey into the world of paleontology as it is conducted in the land under the aurora.Par Pascal Godefroit. 2012
In 1878, the first complete dinosaur skeleton was discovered in a coal mine in Bernissart, Belgium. Iguanodon, first described by…
Gideon Mantell on the basis of fragments discovered in England in 1824, was initially reconstructed as an iguana-like reptile or a heavily built, horned quadruped. However, the Bernissart skeleton changed all that. The animal was displayed in an upright posture similar to a kangaroo, and later with its tail off the ground like the dinosaur we know of today. Focusing on the Bernissant discoveries, this book presents the latest research on Iguanodon and other denizens of the Cretaceous ecosystems of Europe, Asia, and Africa. Pascal Godefroit and contributors consider the Bernissart locality itself and the new research programs that are underway there. The book also presents a systematic revision of Iguanodon; new material from Spain, Romania, China, and Kazakhstan; studies of other Early Cretaceous terrestrial ecosystems; and examinations of Cretaceous vertebrate faunas.Par Claudia Tambussi, Federico Degrange. 2012
Modern birds (Neornithes) are represented by two big lineages, the Palaeognathae (Tinamiformes + Ratitae) and the Neognathae [Galloanserae + Neoaves…
(Metaves + Coronoaves)]. Both clades sum approximately 10,000 species of which 60% are Passeriformes (the most diverse clade of terrestrial vertebrates). A comparison between the past and the present reveals a complex and hallmarked evolutionary and biogeographic history which would have begun over 65 million years ago. For South America (SA) this includes: (1) the presence of taxa with uncertain affinities and the absence of Passeriformes during the Paleogene; (2) a progressive and accelerated increase of the species starting at the Neogene (Miocene); (3) important extinct lineages (e.g. Phorusrhacidae, Teratornithidae) that migrate to North America after the rising of the Panamá isthmus; (4) groups with major diversification in the Neogene that survives nowadays represented by scarce species endemic of SA (Cariamidae) or that inhabits mainly in the southern hemisphere (Anhingidae); (5) very diverse living groups with scarce (e.g., Passeriformes) or none (e.g., Apodiformes) fossil record in SA, which stem-groups are registered in Europe. Apparently, the changes in diversity of the south American Neornithes have been the result of successive radiation, biogeographic connections with North America and in a minor scale, some extinctions. The opening of the Drake´s passage and the occurrence of the circumpolar Antarctic flow are not sufficient causes to explain the highly disparity between the weddelians penguins (Sphenisciformes) of Antartica and those of the patagonian Atlantic Ocean.Par Jennifer A. Clack, Arthur N. Popper, Richard R Fay. 2016
The evolution of vertebrate hearing is of considerable interest in the hearing community. However, there has never been a…
volume that has focused on the paleontological evidence for the evolution of hearing and the ear, especially from the perspective of some of the leading paleontologists and evolutionary biologists in the world. Thus, this volume is totally unique, and takes a perspective that has never been taken before. It brings to the fore some of the most recent discoveries among fossil taxa, which have demonstrated the sort of detailed information that can be derived from the fossil record, illuminating the evolutionary pathways this sensory system has taken and the diversity it had achieved.Par Andrew Parker. 2003
About 550 million years ago, there was literally an explosion of life forms, as all the major animal groups suddenly…
and dramatically appeared. Although several books have been written about this surprising event, known as the Cambrian explosion, none has explained why it occurred. Indeed, none was able to. Here, for the first time, Oxford zoologist Andrew Parker reveals his theory of this great flourishing of life. Parker's controversial but increasingly accepted "Light Switch Theory" holds that it was the development of vision in primitive animals that caused the explosion. Drawing on evidence not just from biology, but also from geology, physics, chemistry, history, and art, In the Blink of an Eye is the fascinating account of a young scientist's intellectual journey, and a celebration of the scientific method.Par Mark E, Patzkowsky, Steven Holland. 2012
Whether the fossil record should be read at face value or whether it presents a distorted view of the history…
of life is an argument seemingly as old as many fossils themselves. In the late 1700s, Georges Cuvier argued for a literal interpretation, but in the early 1800s, Charles Lyell's gradualist view of the earth's history required a more nuanced interpretation of that same record. To this day, the tension between literal and interpretive readings lies at the heart of paleontological research, influencing the way scientists view extinction patterns and their causes, ecosystem persistence and turnover, and the pattern of morphologic change and mode of speciation. With Stratigraphic Paleobiology, Mark E. Patzkowsky and Steven M. Holland present a critical framework for assessing the fossil record, one based on a modern understanding of the principles of sediment accumulation. Patzkowsky and Holland argue that the distribution of fossil taxa in time and space is controlled not only by processes of ecology, evolution, and environmental change, but also by the stratigraphic processes that govern where and when sediment that might contain fossils is deposited and preserved. The authors explore the exciting possibilities of stratigraphic paleobiology, and along the way demonstrate its great potential to answer some of the most critical questions about the history of life: How and why do environmental niches change over time? What is the tempo and mode of evolutionary change and what processes drive this change? How has the diversity of life changed through time, and what processes control this change? And, finally, what is the tempo and mode of change in ecosystems over time?
