This book was released on 2020-03-12 with total page 243 pages. Available in PDF, EPUB and Kindle. Book excerpt: Evolution of the horse has been an often-cited primary example of evolution, as well as one of the classic and important stories in paleontology for over a century and a half, due to their rich fossil record across 5 continents: North America, South America, Europe, Asia and Africa. The recent horse has served a profound role in human ancestry, including agriculture, commerce, sport, transport, warfare, and in prehistory, for the subsistence of humans. Many studies have examined the evolution of the Equidae and chronicled the striking changes in skulls, dentition, limbs, and body size which have long been perceived to be a response to environmental shifts through time. Most comprehensive studies heretofore have: (1) focused on the “Great Transformation”- changes that occurred in the early Miocene, (2) involved tracking long-term diversity or paleoecological trends on a single continent or within a geographical locality, or (3) concentrated on the 3-toed hipparions. The Plio–Pleistocene evolutionary stage of horse evolution is punctuated by the great climatic fluctuations of the Quaternary beginning 2.6 Ma which influenced Equus evolution, biogeographic dispersion and adaptation on a nearly global scale. The evolutionary biology of Equus evolution across its entire range remains relatively poorly understood and often highly controversial. Some of this lack of understanding is due to assumptions that have arisen because of the relatively derived craniodental and postcranial anatomy of Equus and its close relatives which has seemed to imply that that these forms occupied relatively homogenous and narrow dietary and locomotor niches - notions that have not been adequately addressed and rigorously tested. Other challenges have revolved around teasing apart environmentally-driven adaptation versus phylogenetically defined morphological change. Geochronologic age control of localities, geographic provinces and continents has improved, but in no way is absolute and can be reexamined in our proposed volume. Temporal resolution for paleodietary, paleohabitat and paleoecological interpretations are also challenging for understanding the evolution of Equus. Our proposed volume attempts to assemble a group of experts who will address multiple dimensions of Equus’ evolution in time and space.

Janis and published by Cambridge University Press. This book was released on 1998-05-28 with total page 712 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is designed as a source and reference for people interested in the history and fossil record of North American tertiary mammals.

Book Synopsis Revision of the Miocene and Pliocene Equidae of North America by : James Williams Gidley
Download or read book Revision of the Miocene and Pliocene Equidae of North America written by James Williams Gidley and published by . This book was released on 1907 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: "In the foregoing revision the lines of comparison and study have been confined principally to characters of the teeth and skull, for the reason that by far the greater number of species of horses have been founded on tooth and skull material not associated with other parts of the skeleton. The expeditions of the last few years however are constantly increasing the collections and adding quantities of more complete material, including many specimens in which teeth and bones of the feet are associated. This class of material will greatly aid in working out more fully than has been done the characters of foot development of horses, and should result in throwing added light on the phyletic relations of the extremely varied groups which seem to have reached their culmination, as regards numbers of genera and species, in the Miocene period. The principal results attained by this study are, first, a better understanding and interpretation of the principal characters shown in the numerous and varied types representing the American Miocene horses; second, the reestablishment and better definition of several of the genera and species proposed by Leidy, the validity of which was questioned by Cope; and third, a reclassification of the entire family of the Equiidae. As at present understood, the fact seems to be fairly well established that there is a considerable phyletic hiatus between the groups of the Equidae as above subdivided, which are as yet not bridged over by intermediate forms. Such a hiatus seems especially marked between the Anchitheriinae and the Protohippinae, while these groups greatly overlap each other in time. So far as indicated by any known species the Anchitheriinae could not well have stood in direct ancestral line to the latter group or to the Equiinae. There seems also to be almost as decided a gap between the Anchitheriinae and the known species of the older group, the Hyracotheriinae. The Equiinae may well have been derived from some species of the Protohippus division of the Protohippinae"--Page 933-934

Book Synopsis European Neogene Mammal Chronology by : Everett H. Lindsay
Download or read book European Neogene Mammal Chronology written by Everett H. Lindsay and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 657 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the last ZO years great progress has been achieved in our understanding of both earth history and vertebrate evolution. The result is that climatic/tectonic events in earth history can now be placed in a more precise and global time frame, that permit their evaluation as abiotic causal factors which might trigger extinction and dispersal events in vertebrate history. Great strides have also been made in genetics and cell biology, providing new insight into phylogenetic relationships among many vertebrates. These new data, along with data on chronologie resolution of earth history, provide tests of previous interpretations regarding ancestral-descendant relationships based solely on the fossil record. It is fitting and proper that a volume on European Neogene mammal chronology is produced at this time, to ensure that new interpretations of vertebrate evolution and chronology are based on the most accurate and current data. Vertebrate paleon tologists believe that the fossil record is the only secure data for measuring the actual course and tempo of vertebrate evolution. Knowledge of the fossil record must keep pace with advances in other areas of science so that inferences on vertebrate evolu tion are accurate and meaningful.

Book Synopsis A Concise Dictionary of Paleontology by : Robert L. Carlton
Download or read book A Concise Dictionary of Paleontology written by Robert L. Carlton and published by Springer Nature. This book was released on 2019-10-18 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: This new and significantly updated authored dictionary is a unique glossary of paleontological terms, taxa, localities, and concepts. It focuses primarily on identifying the most significant groups of fossil animals and plants in relation to their evolution and phylogeny. It also focuses on mass extinctions, on taxa that are problematic in some significant way, on the principal fossil-Lagerstätten of the world, and on historical turning points marked by index fossils. Although there are many current resources on the subject, none contains an accurate representation of the paleontological lexicon. Although well aware that the fast-changing field of paleontology will always defy any attempt at complete description, the author has attempted to provide an accurate and comprehensive set of about 4,000 entries that will be useful to professionals as well as to general readers of scientific literature without a background in paleontology.
