Download or read book Bryozoan Paleobiology written by Paul D. Taylor and published by John Wiley & Sons. This book was released on 2020-07-08 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryozoa are among the most abundant yet least understood of phyla in the fossil record. These exclusively colonial animals can be traced back to the Ordovician as fossils and are common elements of sediments deposited in shallow marine environments. On occasion their calcareous skeletons are sufficiently numerous to produce bryozoan limestones. The potential of bryozoans in facies analysis, and their use in macroevolutionary studies, have both been widely recognised, but to date have been incompletely exploited. Bryozoan Paleobiology brings together the scattered research on living and fossil bryozoans in broad and profusely illustrated overview that will help students and researchers alike in understanding this fascinating group of animals. Beginning with the basics of bryozoan morphology, ecology and classification, the book progresses from the smallest scale of skeletal ultrastructure, to the largest of bryozoan distributions in time and space. On the way, topics such as the origin of zooidal polymorphism and macroevolutionary trends in colony forms are covered. Case studies illuminate these topics, and areas in which further research is particularly required are highlighted.
Download or read book Bryozoan Studies 2010 written by Andrej Ernst and published by Springer Science & Business Media. This book was released on 2012-06-05 with total page 465 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryozoa are a colonial animal phylum with a long evolutionary history, having existed from the early Ordovician (480 My) onward and still flourishing today. Several mass extinctions in earth history shaped and triggered bryozoan evolution through drastic turnover of faunas and new evolutionary lineages. Bryozoa are widespread across all latitudes from Equator to Polar Regions and occur in marine and freshwater environments. They are shaping benthic ecosystems and recording ambient environmental conditions in their skeletons. The book provides a synthesis of the current main topics of research in the field of Bryozoology including combined research on both extant, and extinct taxa. Fields or current research span molecular genetics and phylogeny, life history, reproduction and anatomy, biodiversity and evolutionary patterns in time and space, taxonomy, zoogeography, ecology, sediment interactions, and climate response.
Download or read book Bryozoan Studies 2022 written by Marcus M. Key and published by CRC Press. This book was released on 2023-12-15 with total page 204 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryozoan Studies 2022 contains nineteen papers presented at the 19th International Conference of the International Bryozoology Association held at Trinity College Dublin in August 2022. Bryozoans are complex and fascinating colonial organisms that range from Cambrian to the present day and which are found in marine and freshwater environments from pole to pole and subtidal to abyssal. Recent tomographic techniques have revolutionised the study of modern and fossil taxa where internal structures are revealed through non-destructive methodologies. Here the internal structure of some Ordovician and Eocene taxa is illustrated through these methods. Phylogenetic studies of bryozoans question the classic classification of the group; here the phylogeny of species from California and Japan is described. Other topics covered are assessments of Recent faunas from Haiti and fossil assemblages from Mexico and the United States. Distributional patterns from the Arctic and New Zealand and the dispersal patterns of bryozoans on rafted pumice and on slipper lobsters are characterised. Further contributions provide descriptions of a rare Permian taxon, clarification of species assigned to the Upper Palaeozoic genus Stenopora, avicularia in Wilbertopora, enigmatic structures in a fenestrate bryozoan, repair structures in trepostomes, and an assessment of skeletonisation in the families of Palaeozoic orders.

Download or read book Species and Speciation in the Fossil Record written by Warren D. Allmon and published by University of Chicago Press. This book was released on 2016-10-05 with total page 434 pages. Available in PDF, EPUB and Kindle. Book excerpt: The literature of paleobiology is brimming with qualifiers and cautions about using species in the fossil record, or equating such species with those recognized among living organisms. Species and Speciation in the Fossil Record digs through this literature and surveys the recent research on species in paleobiology. In these pages, experts in the field examine what they think species are - in their particular taxon of specialty or more generally in the fossil record. They also reflect on what the answers mean for thinking about species in macroevolution. The first step in this approach is an overview of the Modern Synthesis, and paleobiology’s development of quantitative ways of documenting and analyzing variation with fossil assemblages. Following that, this volume’s central chapters explore the challenges of recognizing and defining species from fossil specimens, and show how with careful interpretation and a clear species concept, fossil species may be sufficiently robust for meaningful paleobiological analyses. Tempo and mode of speciation over time are also explored, exhibiting how the concept of species, if more refined, can reveal enormous amounts about the interplay between species origins and extinction and local and global climate change.

Download or read book A Concise Dictionary of Paleontology written by Robert L. Carlton and published by Springer. This book was released on 2020-10-31 with total page 469 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.
Download or read book Echinoderm Paleobiology written by William I. Ausich and published by Indiana University Press. This book was released on 2008-07-18 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: The dominant faunal elements in shallow Paleozoic oceans, echinoderms are important to understanding these marine ecosystems. Echinoderms (which include such animals as sea stars, crinoids or sea lilies, sea urchins, sand dollars, and sea cucumbers) have left a rich and, for science, extremely useful fossil record. For various reasons, they provide the ideal source for answers to the questions that will help us develop a more complete understanding of global environmental and biodiversity changes. This volume highlights the modern study of fossil echinoderms and is organized into five parts: echinoderm paleoecology, functional morphology, and paleoecology; evolutionary paleoecology; morphology for refined phylogenetic studies; innovative applications of data encoded in echinoderms; and information on new crinoid data sets.

Download or read book Australian Bryozoa Volume 2 written by Haylee Weaver and published by CSIRO PUBLISHING. This book was released on 2018-07-01 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bryozoans are aquatic animals that form colonies of connected individuals. They take a variety of forms: some are bushy and moss-like, some are flat and encrusting and others resemble lace. Bryozoans are mostly marine, with species found in all oceans from sublittoral to abyssal depths, but freshwater species also exist. Some bryozoans are of concern as marine-fouling organisms and invasive species, while others show promise as sources of anticancer, antiviral and antifouling substances. Written by experts in the field, Australian Bryozoa Volume 2: Taxonomy of Australian Families is the second of two volumes describing Australia’s 1200 known species of bryozoans, the richest diversity of bryozoans of any country in the world. It contains detailed taxonomic data and illustrated family-level treatments, which can be used to identify specimens. It provides an authoritative reference for biology students, academics and others interested in marine biology.
