This book was released on 2016-08-19 with total page 726 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Late Cenozoic Gastropods From Northern Venezuela Two hundred and eighty-eight species of gastropods, ranging in age from late Miocene to Recent, are described, compared, and illustrated. Of the total, 163 species or subspecies are believed to be new, and among those are 5 new subgenera and 3 new genera. The fossil gastropods are from La Salina de Guaiguaza in the State of Carabobo, and from Cabo Blanco in the Distrito Federal. The Recent gastropods are from Cabo Blanco (at Playa Grande) and from Higuerote, in the State of Miranda. The largest number of fossils (224) are described from the Cabo Blanco group which, from bottom to top is made up of the following formations: Las Pailas, Playa Grande, Mare, and Abisinia. The lowest formation - the Las Pailas - is unfossiliferous. The overlying Playa Grande is divided into two members, the Catia below, and the Maiquetia above. Based solely on the evidence of l the gastropods and stratigraphic posi tion, it is tentatively suggested that the Catia member is of later Miocene age, the Maiquetia member upper Miocene - Pliocene, the Mare formation Pliocene, and the Abisinia Pleistocene.

Available in PDF, EPUB and Kindle. Book excerpt: With all the recent advances in molecular and evolutionary biology, one could almost wonder why we need the fossil record. Molecular sequence data can resolve taxonomic relationships, experiments with fruit flies demonstrate evolution and development in real time, and field studies of Galapagos finches have provided the strongest evidence for natural selection ever measured in the wild. What, then, can fossils teach us that living organisms cannot? Evolutionary Patterns demonstrates the rich variety of clues to evolution that can be gleaned from the fossil record. Chief among these are the major trends and anomalies in species development revealed only by "deep time," such as periodic mass extinctions and species that remain unchanged in form for millions of years. Contributors explore modes of development, the tempo of speciation and extinction, and macroevolutionary patterns and trends. The result is an important contribution to paleobiology and evolutionary biology, and a spirited defense of the fossil record as a crucial tool for understanding evolution and development. The contributors are Ann F. Budd, Efstathia Bura, Leo W. Buss, Mike Foote, Jörn Geister, Stephen Jay Gould, Eckart Hâkansson, Jean-Georges Harmelin, Lee-Ann C. Hayek, Jeremy B. C. Jackson, Kenneth G.

This book was released on 2013-04-02 with total page 251 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shallow water marine molluscan faunas are distributed in a pattern of distinct, geographically definable areas. This makes mollusks ideal for studying the distribution of organisms in the marine environment and the processes and patterns that control their evolution. Biogeography and Biodiversity of Western Atlantic Mollusks is the first book to us
Download or read book Conus of the Southeastern United States and Caribbean written by Alan J. Kohn and published by Princeton University Press. This book was released on 2014-08-31 with total page 477 pages. Available in PDF, EPUB and Kindle. Book excerpt: Conus is the largest genus of animals in the sea, occurring throughout the world's tropical and subtropical oceans and contributing significantly to marine biodiversity. The shells of these marine mollusks are prized for their amazing variety and extraordinary beauty. The neurotoxic venoms they produce—injected by a hollow, harpoon-like tooth into prey animals that are then paralyzed and swallowed whole—have a range of pharmaceutical applications, from painkillers to antidepressants. This beautifully illustrated book identifies 53 valid species of the southeastern United States and the Caribbean, a region that supports a diverse but taxonomically challenging group of Conus. Introductory chapters cover the evolution and phylogeny of the genus, and notes on methodology are provided. Detailed species accounts describe key identification features, taxonomy, distribution, ecology, toxicology, life history, and evolutionary relationships. The book includes more than 2,100 photos of shells on 109 splendid color plates; more than 100 additional photos, many depicting live animals in color; and 35 color distribution maps. Identifies 53 valid species—the first reassessment of western Atlantic Conus in more than seventy years Features more than 2,100 photos of shells on 109 color plates Blends the traditional shell-character approach to identification with cutting-edge shell and radular tooth morphometrics and molecular genetic analyses Includes color images of live animals as well as color distribution maps
Download or read book Tropical Marine Mollusks written by Edward J. Petuch and published by CRC Press. This book was released on 2020-12-10 with total page 374 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marine biogeography, the study of the spatial distribution of organisms in the world’s oceans, is one of the most fascinating branches of oceanography. This book continues the pioneering research into the distributions of molluscan faunas, first studied by biologists over 160 years ago. It illustrates 1778 species of gastropods in full color, many of which are extremely rare and poorly known endemic species that are illustrated for the first time outside of their original descriptions. The spatial arrangements of malacofaunas shown in this book can be considered proxies for worldwide oceanic conditions and used as tools for determining patterns of global climate change. The book's documentation of evolutionary "hot spots" and geographically restricted endemic faunas can also be used as a base line for future studies on patterns of environmental deterioration and extinction in the marine biosphere. Documenting the evolution of the amazingly rich worldwide gastropod fauna, this book will appeal to physical and chemical oceanographers, systematic and evolutionary biologists, historical geologists, paleontologists, climatologists, geomorphologists, and physical geographers. The authors incorporate aspects of all of these disciplines into a new classification system for the nomenclature of biogeographical spatial units found in tropical, subtropical, and warm temperate seas.
