Download E-books Molluscan Paleontology of the Chesapeake Miocene PDF

By Edward J. Petuch

The Chesapeake Miocene will consistently be thought of a paleontological treasure. Given the richness and accessibility of the Maryland and Virginia Miocene shell beds, it kind of feels amazing that only a few humans have ever defined new species from those strata over the last 185 years. before. Integrating components from paleontology, geology, environmental technological know-how, and ecology, Molluscan Paleontology of the Chesapeake Miocene assembles past study and the authors’ adventure right into a synoptic box guide.

The so much entire compendium of Miocene species created due to the fact 1904, this long-awaited source lists approximately 500 species. It comprises illustrations of 260 species, together with greater than 60 no longer present in any past publication and 26 newly found. It describes Chesapeake molluscan faunas by way of neighborhood geology, paleoceanography, and marine paleobiology. prepared by means of stratigraphic geology, the publication covers fossils of the Eastover, St Mary’s, Choptank, and Calvert Formations. It illustrates 24 accumulating websites and fossil exposures, exhibiting information of in situ specimens, besides maps of four Miocene paleoseas and specific stratigraphic columns for Maryland and northerly Virginia. The textual content is followed via a CD-ROM with colour illustrations of the 40 identified species of ecphora shells. Armed with those, you have to be in a position to establish the species present in the amazingly wealthy shell beds of the Chesapeake Bay quarter.

Download E-books Dragon Bone Hill: An Ice-Age Saga of Homo erectus PDF

By Noel Thomas Boaz

"Peking Man," a cave guy as soon as proposal an excellent hunter who had first tamed fireplace, really was once a composite of the gnawed is still of a few fifty girls, young ones, and males unlucky sufficient to were the prey of the large cave hyena. discovering the recognized fossil web site of Dragon Bone Hill in China, scientists Noel T. Boaz and Russell L. Ciochon retell the tale of the cave's detailed species of early human, Homo erectus.
Boaz and Ciochon take readers on a gripping clinical odyssey. New proof exhibits that Homo erectus used to be an opportunist who rode a tide of environmental switch out Africa and into Eurasia, puddle-jumping from one gene pool to the subsequent. Armed with a shaky carry on fireplace and a few sharp rocks, Homo erectus tremendously survived for over 1.5 million years, for much longer than our personal species Homo sapiens has been in the world. Tell-tale marks on fossil bones exhibit that the lives of those early people have been brutal, governed via starvation and who may well strike the toughest blow, but there are fleeting glimpses of human compassion to boot. The small mind of Homo erectus and its surprisingly unchanging tradition point out that the species couldn't speak. a part of that primitive tradition integrated ritualized aggression, to which the tremendous thick skulls of Homo erectus undergo mute witness.
either a brilliant game of the unimagined lifestyle of a prehistoric species, so comparable but so in contrast to us, and a desirable exposition of ways sleek multidisciplinary learn can try hypotheses in human evolution, Dragon Bone Hill is technology writing at its best.

Download E-books Ecology and Evolution in Anoxic Worlds (Oxford Series in Ecology and Evolution) PDF

By Tom Fenchel

Anoxic conditions--the environments during which lifestyles began--still persist in lots of locations on the earth, comparable to in lake sediments, the center of ruminants, and the deep waters of a few marine basins. Ecology and Evolution in Anoxic Worlds bargains a present and unified traditional heritage of oxygen-free environments and their microbial population. Drawing on proof from quite a few medical disciplines, the authors--two prime researchers within the field--describe the forces identified to form the constitution, functionality, heterogeneity, and evolution of anaerobic groups. themes variety from the foundation and upkeep of anoxic habitats all through Earth's heritage to the beginning of prokaryotes, eukaryotes, and eukaryotic organelles to the advance of microbial groups. specific emphasis is put on how energy-yielding pathways that have developed in anaerobic microorganisms dictate the syntrophic and aggressive interactions that form anaerobic microbial neighborhood improvement. The ecological and evolutionary value of the arriving of oxygen within the Proterozoic is mentioned intimately. wonderfully readable, Ecology and Evolution in Anoxic Worlds brings an interdisciplinary subject of growing to be curiosity updated. it will likely be wanted via scholars and researchers in ecology, microbiology, biochemistry, zoology, evolutionary biology, geology, marine biology, and oceanography.

Published via the yankee Geophysical Union as a part of the AGU Reference Shelf sequence, quantity 4.

Quaternary geochronology is the sector dedicated to relationship Earth's historical past of the previous 1.8 million years, the Quaternary interval. the sphere has come some distance for the reason that its early formulations before everything of the 20 th century and the appearance of radiocarbon courting 50 years in the past. on the grounds that that point the sphere has witnessed a manifold raise within the variety of on hand courting tools, not anyone of which could do all that the sum can provide.

It turns out applicable that this quantity, that is dedicated to the topic of usual time, be released on the finish of the second one millennium, a second additionally major in a cultural experience. it's one of many very purposes that we compiled this quantity; in order that we would larger inform the background of the Earth in the course of the Quaternary Period—the time during which the human species developed and through which all that we all know as background occurred.

Download E-books The White River Badlands: Geology and Paleontology (Life of the Past) PDF

By Rachel C. Benton, Dennis O., Jr. Terry, Emmett Evanoff, Hugh Gregory McDonald

The forbidding giant Badlands in Western South Dakota comprise the richest fossil beds on the earth. Even this day those rocks proceed to yield new specimens delivered to gentle by way of snowmelt and rain washing away smooth rock deposited on a floodplain in the past. the standard and volume of the fossils are tremendous: lots of the species to be came upon there are recognized from hundreds and hundreds of specimens. The fossils within the White River staff (and comparable deposits within the American west) defend the full past due Eocene during the center Oligocene, approximately 35-30 million years in the past and greater than 30 million years after non-avian dinosaurs turned extinct. The fossils supply a close checklist of a interval of abrupt international cooling and what occurred to creatures who lived via it. The e-book offers a finished connection with the sediments and fossils of the large Badlands and may supplement, increase, and in many ways exchange the vintage 1920 quantity via Cleophas C. O'Harra. as the e-book specializes in a countrywide treasure, it touches on nationwide Park provider administration regulations that support shield such major fossils.

The targets of this quantity are twofold. First, it goals to supply a singular concentrate on adaptive causes for cranial and postcranial positive aspects and sensible complexes, socioecological platforms, lifestyles background styles, and so on. in early primates. moment, it goals to provide an in depth rendering of the phylogenetic affinities of such basal taxa to later primate clades in addition to to different early/recent mammalian orders. therefore, as well as the strictly paleontological or systemic questions relating to Primate Origins, the editors plan to pay attention to the adaptive value of primate features. those questions are top approached via either paleontological and neontological comparative learn on various primate and non-primate fabrics. the amount is well timed since it capitalizes on an expanding and demanding measure of novel self sustaining museum, box and laboratory dependent examine on a few of the vital remarkable concerns concerning primate origins. additionally, by means of integrating such disparate assets of experimental, comparative, paleontological, ecological and molecular info right into a unmarried edited quantity, it offers the broadest attainable standpoint on early primate phylogeny and the adaptive forte of the Order Primates.
