Excerpt: ...of the posterior margin, part being above and part below the rounded angle formed at the junction of the vertical posterior end and the actinal surface. The space enclosed is large and sub reniform in outline, and the upper part of the fasciole dips down with a rather deep Three pairs of pores reentering curve, pointing downwards, in the median line. belonging to the posterior zone of the posterior petals are included within the fasciole, and mark its lateral boundaries. The presence of a peripetalous fasciole is very doubtful. In none of the specimens is the delicate ornamentation of the test within the region of the petals sufficiently well preserved to enable this point to be settled. In one of the specimens which has some portions fairly well preserved an arrangement of granulation may be observed at the extremity of the antero-lateral petal, and extending for a short distance close along the posterior margin of the groove, which is rather suggestive of a fasciole. There is also a slight tumidity on one of the plates about midway on the anterior margin of the posterior petal, which might possibly indicate the line of direction taken by the supposed fasciole in crossing the postero-lateral interradium; but no actual band is discernible. The strip of granulation above referred to is, however, somewhat ill-defined, and wanting in compactness--a fact which, together with the inability of finding any trace of the fasciolestructure elsewhere, leads us to entertain very great doubts as to the presence of a second fasciole in the Spatangoid under notice. Remarks. This very interesting form is readily distinguishable either from its congeners or any species with which we are acquainted. At first sight it strongly suggests the outline of...

Download or read book The Indian Paleogene written by Sunil Bajpai and published by Springer. This book was released on 2018-04-24 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: This unique book provides a concise account of Indian Paleogene and presents a unified view of the Paleogene sequences of India. The Paleogene, comprising the early part of the Cenozoic Era, was the most dynamic period in the Earth’s history with profound changes in the biosphere and geosphere. The period spans ~42 million years, beginning from post- K/T mass extinction event at ~65 Ma and ending at ~23 Ma, when the first Antarctic ice sheet appeared in the Southern Hemisphere. The early Paleogene (Paleocene–Eocene) has been considered a globally warm period, superimposed on which were several transient hyperthermal events of extreme warmth. Of these, the Palaeocene Eocene Thermal Maxima (PETM) boundary interval is the most prominent extreme warming episode, lasting 200 Ka. PETM is characterized by 2–6‰ global negative carbon isotope excursion. The event coincided with the Benthic Extinction Event (BEE) in deep sea and Larger Foraminifera Turnover (LFT) in shallow seas. Rapid ~60–80 warming of high latitudinal regions led to major faunal and floral turnovers in continental, shallow-marine and deep-marine areas. The emergence and dispersal of mammals with modern characteristics, including Artiodactyls, Perissodactyls and Primates (APP), and the evolution and expansion of tropical vegetation are some of the significant features of the Paleogene warm world. In the Indian subcontinent, the beginning and end of the Paleogene was marked by various events that shaped the various physiographic features of the Indian subcontinent. The subcontinent lay within the equatorial zone during the earliest part of the Paleogene. Carbonaceous shale, coal and lignite deposits of early Eocene age (~55.5–52 Ma) on the western and north-eastern margins of the Indian subcontinent are rich in fossils and provide information on climate as well as the evolution and paleobiogeography of tropical biota. Indian Paleogene deposits in the India–Asia collision zone also provide information pertaining to the paleogeography and timing of collision. Indian Paleogene rocks are exposed in the Himalayan and Arakan mountains; Assam and the shelf basins of Kutch–Saurashtra, Western Rajasthan; Tiruchirappalli–Pondicherry and Andaman and, though aerially limited, these rocks bear geological evidence of immense importance.

Download or read book Ecology and Conservation of Tropical Marine Faunal Communities written by K. Venkataraman and published by Springer Science & Business Media. This book was released on 2013-09-12 with total page 484 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides insights into various aspects of marine faunal communities in India, which are extremely diverse due to the geomorphologic and climatic variations along the Indian coasts. Consisting of 30 chapters by experts in their respective fields, it is divided into two parts: · Part I: Tropical Marine Faunal Communities · Part II: Ecology and Conservation Part I highlights the diversity and distribution of Foraminifera; sponges associated with seagrass; Polychaeta; Opisthobranchia; oysters; copepods; horseshoe and brachyuran crabs; echinoderms; ascidians; fishes; fish parasites; and sea mammals. Topics of Part II include the status and environmental parameters of benthos; the status of coral reefs; the invasion of snowflake coral; the recovery of bleached corals; the socioeconomics and management of dugong; marine biodiversity conservation and management in India; the assessment of the marine fauna of the Indian Wildlife Protection Act; and marine biodiversity protected areas in India. This book will serve as a valuable reference work for marine scientists, as well as for environmental managers and policy makers.
