Book excerpt: Excerpt from A Monograph of the Entomostraca of the Cretaceous Formation of England Of the numerous microscopic organisms afforded by the disintegration of the Oolitic, Cretaceous, and Tertiary strata, whether calcareous, argillaceous, or sandy, the Polythalamia and the Entomostraca are by far the most abundant. The latter attract observation by their larger relative size, but have not been hitherto very extensively described. Our present observations are confined to the Entomostraca of the Cretaceous Formation, comprising the Chalk, Chalk-marl, Gault, and Greensand. The strata that have afforded the species herein described are the greensand beds of Blackdown (siliceous), of Warminster (calcareous), and of Farringdon (arenaceous); the Speeton Clay; the Gault of Folkstone and of Leacon Hill, near Charing; the Grey Chalk and Chalk-marl of Dover; the Cretaceous Detritus of Charing; the Red Chalk of Flamborough; and the common White Chalk of the south-east of England. In the above-mentioned strata these little fossils lie about irregularly in all directions, and are not found in layers such as are often formed by the Entomostraca of the Wealden and Tertiary beds; many are broken or eroded, and some bear evidence of having been crushed whilst in a recent state. The animal matter of the carapace is well preserved in the Gault specimens, and more or less so in others; individuals bearing a trace of transparency and of original colouring occur, but are extremely rare, in the Chalk; whilst in the Gault a large proportion remains transparent. The specimens generally occur as separate valves, but perfect carapaces are not unfrequently found, the latter condition being dependent upon the strength of the hinge attachment, which varies considerably in different species.

Book excerpt: Excerpt from A Monograph of the Tertiary Entomostraca of England With regard to the sources from whence I have derived the materials for the present Monograph, I have first to acknowledge the value of Mr. S.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from A Supplementary Monograph: Of the Tertiary Entomostraca of England The Tertiary Bntomostraca (Ostracoda) of England, at first treated of in a Monograph for the Palontographical Society in 1857, were revised by one of us in the 'Geological Magazine, ' 1870, pp. 155 - 159. The researches of G. O. Sars and G. S. Brady, with D. Robertson and others, elucidating the relationships of the genera and species among recent forms, gave effect in a great degree to that revision; and their continued labours have further helped us. Since the publication of the Revision, eighteen years ago, besides there being some additional corrections to be noticed, several new species have come to hand, late research in the fossiliferous deposits of Tertiary age having enabled our friends to add to the collections we have made for ourselves, so that the known English Tertiary forms are now upwards of one hundred in number. The British Post-Tertiary species are still more numerous. Some of the latter were described in the Monograph for year 1855 (dated on title-page 1856, but issued in 1857), and what relates to them in the new researches is here noticed. The notices and descriptions of revised and new forms will be arranged according to their alliances, and as far as possible in a Natural Order, in accordance with the grouping of genera adopted by Dr. G. S. Brady in his latest memoirs on recent Ostracoda. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Download or read book Ostracods in British Stratigraphy written by J. E. Whittaker and published by Geological Society of America. This book was released on 2009 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book charts the stratigraphical distribution of ostracods in the Cambrian to Pleistocene deposits of Britain and outlines their utility for dating and correlating rock sequences, as well as indicating aspects of their palaeoenvironmental and palaeogeographical significance. These small bivalved crustaceans are the most abundant arthropods in the fossil record. Indeed, the stratigraphy of Britain, which embraces many type-sequences, provides a particularly rich and full record of them, from at least the basal Ordovician, and from the British Cambrian there is a biostratigraphy based on their 'relatives', the bradoriids and phosphatocopids. Ostracod distributions demonstrate the ecological success story of the group, occupying as they do marine, non-marine and even 'terrestrial' habitats. Written by current specialists in the field, this book is an authoritative account and will be welcomed by all micropalaeontologists and applied geologists in the industrial and academic world alike. It is richly illustrated with over 80 plates of electron micrographs and specially drawn maps, diagrams and range-charts.

This book was released on 2021-03-30 with total page 1377 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Arabian Seas Marine Region encompasses marine areas from Djibouti to Pakistan, including the northern part of Somalia, the Red Sea, the Arabian/Persian Gulf, and parts of the Arabian Sea. Human pressures on the coastal and marine environments are evident throughout the region, and have resulted in harmful environmental effects. Oil and domestic, urban and industrial pollutants in several areas of this part of the world have caused local habitat degradation, eutrophication and algal blooms. Further, coastal landfill, dredging, and sedimentation, as well as nutrient and sediment runoff from phosphate mining, agriculture and grazing, and reduction in freshwater seepage due to groundwater extraction are all contributing to the degradation of coastal environments. This book discusses aspects not covered in other books on the region, which largely focus on marine biodiversity, and examines several environmental challenges that are often ignored, but which have a significant impact on the environment. Evaluating the status quo, it also recommends conservation measures and examines the abiotic factors that play a major main role in the environmental changes. Lastly, the book addresses the biodiversity of the area, providing a general context for the conservation and management measures discussed.
