Available in PDF, EPUB and Kindle. Book excerpt: This volume sheds new light on the marine fauna and geological setting of the Tjörnes Sequence, North Iceland, which is a classic site for the Pliocene and Pleistocene stratigraphy of the North Atlantic region. Readers will discover descriptions of new data collected by the editors over a period of over three decades on marine faunal assemblages and sedimentology available for palaeoenvironmental reconstructions, as well as the tectonic and stratigraphical relationships on Tjörnes Peninsula. The book includes a comprehensive account of all the collections of marine fossil invertebrate macrofossils and foraminifera known to the editors from the Tjörnes Sequence. It is expected to elucidate sedimentological and faunal changes from relatively stable Pliocene conditions to highly variable and periodically harsh climatic conditions of recurring Quaternary glaciations. The distribution, recent or fossil, of various species is recorded and pertinent ecological and biological features are also discussed. The Tjörnes Sequence records the Neogene migration of Pacific species into the North Atlantic. Researchers in geology, climate science, environmental science and earth science will find this book particularly valuable.

Available in PDF, EPUB and Kindle. Book excerpt: The incidence of existing marine fauna by latitude and depth is recorded for the Eastern Pacific Ocean and offshore islands. Hypotheses concerning long and short term factors influencing the coast-wide distribution of the bivalve fauna are formulated and examined. Consideration is given to global effects of plate tectonics, continental displacement and environmental factors. Ordination and clustering techniques are used to examine the size and distribution of zoogeographic provinces. Provincial boundaries are presented and the characteristics of these provinces are described.

This book was released on 2019-11-04 with total page 156 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book identifies all valid species belonging to the superfamily Mactroidea living in American waters, distributed across fourteen biogeographical provinces. It also provides an updated classification of the widely occurring Mactroidea superfamily, which comprises eight subfamilies grouped into four families: Mactridae (Lamarck, 1809); Anatinellidae (Deshayes, J.Gray 1853); Cardiliidae (Fischer, 1887) and Mesodesmatidae (J. Gray, 1840). The species included in this superfamily are known to have existed in North America since the Early Cretaceous.
