Download or read book Sea Mammals written by Annalisa Berta and published by Princeton University Press. This book was released on 2023-09-26 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: A richly illustrated introduction to the world’s living and extinct sea mammals From the gregarious sea otter and playful dolphins to the sociable narwhal and iconic polar bear, sea mammals are a large, diverse, and increasingly precious group. In this book, Annalisa Berta, a leading expert on sea mammals and their evolution, presents an engaging and richly illustrated introduction to past and present species of these remarkable creatures, from the blue whale and the northern fur seal to the extinct giant sperm whale, aquatic sloth, and walking sea cow. The book features more than 50 individual species profiles, themed chapters, stunning photographs, and specially commissioned paleo-illustrations of extinct species. It presents detailed accounts of these mammals’ evolutionary path, anatomy, behavior, habitats, and conservation. And because these are key species that complete many food chains and have the widest influence of all sea life, the book also offers insights into a broad variety of marine worlds today and in the future.

Available in PDF, EPUB and Kindle. Book excerpt: A compelling look at the evolutionary history of marine mammals over the past 50 million years. Marine mammals have long captured the attention of humans. Ancient peoples etched seals and dolphins on the walls of Paleolithic caves; today, engineers develop microprocessors to track these denizens of the deep. This groundbreaking book from highly respected marine mammal paleontologist Annalisa Berta delves into the story of the extraordinary adaptations that gave the world these amazing animals. The Rise of Marine Mammals reveals remarkable fossil record discoveries that shed light on the origins, relationships, and diversification of marine mammals. Focusing on evolution and paleobiology, Berta provides an overview of marine mammal species diversity, enhanced with gorgeous life restorations by Carl Buell, Robert Boessenecker, William Stout, and Ray Troll and extensive line drawings by graphics editor James L. Sumich. The book also considers ongoing conservation challenges, demonstrating how the fossil record of adaptation in response to past environmental shifts may illuminate the way that marine mammals respond to global climate change. This invaluable evolutionary framework is essential for helping us understand how best to protect and conserve today’s polar bears, whales, dolphins, seals, and fellow warm-blooded ocean dwellers. The Rise of Marine Mammals also describes exciting breakthroughs that rely on new techniques of study, including 3-D imaging, and molecular, finite element, and morphometric analyses, which have enhanced scientists’ understanding of everything from the anatomy of fetal whales to the genes behind limb loss in cetaceans. Mammalogists, paleontologists, and marine scientists will find Berta’s insights absorbing, while developmental and molecular biologists, geneticists, and ecologists exploring integrative research approaches will benefit from her fresh perspective.

Available in PDF, EPUB and Kindle. Book excerpt: In this long-awaited sequel Kirk Johnson and Ray Troll are back on a road trip—driving, flying, and boating their way from Baja, California to northern Alaska in search of the fossil secrets of North America's Pacific coast. They hunt for fossils, visit museums, meet scientists and paleonerds, and sleuth out untold stories of extinct worlds. As one of the oldest coasts on earth, the west coast is a rich ground for fossil discovery. Its wonders include extinct marine mammals, pygmy mammoths, oyster bears, immense ammonites, shark-bitten camels, polar dinosaurs, Alaskan palms, California walruses, and a lava-baked rhinoceros. Join in for a fossil journey through deep time and discover how the west coast became the place it is today.

Download or read book Two New Oligocene Desmostylians and a Discussion of Tethytherian Systematics written by Daryl P. Domning and published by . This book was released on 1986 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: A new genus, comprising two new species of desmostylians, is described from marine Oligocene deposits of the Pacific Northwest. Behemotops proteus, new genus, new species, is based on an immature mandibular ramus and apparently associated skeletal fragments from the middle or (more likely) upper Oligocene lower part of the Pysht Formation of Clallam County, Washington. A related new species, Behemotops emlongi, is founded on a mandibular ramus of an old individual and a mandibular fragment with canine tusk from the uppermost Oligocene (early Arikareean equivalent) Yaquina Formation of Lincoln County, Oregon. The two new species are the most primitive known desmostylians and compare favorably with the primitive Eocene proboscideans Anthracobune and Moeritherium, and to the still more primitive tethythere Minchenella from the Paleocene of China.For many years the Desmostylia were widely regarded as members of the mammalian order Sirenia before being accepted as a taxon coordinate with the Sirenia and Proboscidea (Reinhart, 1953). On the basis of cladistic analysis we go a step further and regard the Desmostylia as more closely related to Proboscidea than to Sirenia because the Desmostylia and Proboscidea are interpreted herein to share a more recent common ancestor than either order does with the Sirenia. This analysis also suggests that the common ancestor of the Proboscidea and Desmostylia (but not the Sirenia) had suppressed P5 and the original last molar. These characters may be convergent with some other mammals. The Superorder Tokotheria McKenna, 1975, was originally thought to be characterized by loss of both P5 and M3. However, because early sirenians do not show these losses, they may have occurred independently in the common ancestor of proboscideans and desmostylians and in various other tokotheres.The late Paleocene genus Minchenella Zhang, 1980, from China, is a suitable candidate to be the common ancestor of both the Desmostylia and the Proboscidea. It possesses a small entoconid II on M3. The Eocene genus Lammidhania Gingerich, 1977, from Pakistan, and the late Paleocene and/or early Eocene Chinese and Mongolian phenacolophids had not acquired an entoconid II on M3 but are otherwise similar to Minchenella and the anthracobunids. The Asiatic occurrence of phenacolophids, Lammidhania, Minchenella, and anthracobunids suggests an Asian origin for the Proboscidea and is in accord with the exclusively Pacific distribution of the Desmostylia.We believe that desmostylians were amphibious herbivores that fed on marine algae and angiosperms, and that at least the earlier taxa depended to a large extent on plants exposed in the intertidal zone.
