Significance Of Lepidocyclina

Evolution and Geological Significance of Larger Benthic Foraminifera is a unique, comprehensive reference work on the larger benthic foraminifera. This second edition is substantially revised, including extensive re-analysis of the most recent work on Cenozoic forms. It provides documentation of the biostratigraphic ranges and palaeoecological significance of the larger foraminifera, which is essential for understanding many major oil-bearing sedimentary basins. In addition, it offers a palaeogeographic interpretation of the shallow marine late Palaeozoic to Cenozoic world. Marcelle K. BouDagher-Fadel collects and significantly adds to the information already published on the larger benthic foraminifera. New research in the Far East, the Middle East, South Africa, Tibet and Americas has provided fresh insights into the evolution and palaeographic significance of these vital reef-forming forms. With the aid of new and precise biostratigraphic dating, she presents revised phylogenies and ranges of the larger foraminifera. The book is illustrated throughout, with examples of different families and groups at the generic levels. Key species are discussed and their biostratigraphic ranges are depicted in comparative charts, which can be found at http://discovery.ucl.ac.uk/10047587/2/Charts.pdf.

The over-all aim of the book is to collect and add to the information published already on the larger benthic foraminifera and in cases their associated algae. Many decades of research in the Far East, to some extent in the Middle East and Americas has lead to numerous articles with confused systematics. Therefore, with the aid of new and precise age dates, from calcareous nannofossils and Sr isotopes, the current schemes of the larger foraminifera in a relatively precise chronostratigraphic and sequence stratigraphic framework are revised. This is achieved by: 1) establishing the systematic and occurrences of larger foraminifera from carbonate rocks in successions covering the Carboniferous to Miocene, with careful taxonomic comparison with the known records in the different bioprovinces; 2) illustration fossils of different families and groups at generic levels. 3) illustrations of important species and comparing distributions of different taxa. The inventory of larger benthic foraminifera focuses on the main important groups and the illustration of their genera. Reviews of the global state of the art of each group are complemented with the new data, and the direct palaeobiogeographic relevance of the new data is analyzed. * A unique, comprehensive reference work on the larger foraminifera. * A documentation of the biostratigraphic ranges and palaeoecological significance of larger foraminifera which is essential for understanding many major oil-bearing sedimentary basins. *The palaeogeographic interpretations of the shallow marine late Palaeozoic to Cenozoic world.

Seznam literature o paleogenskih velikih foraminiferah, ki ga je v glavnem sestavil Johannes S. Pignatti, je zelo izčrpen seznam referenc o stratigrafiji, paleoekologiji, morfologiji in taksonomiji paleogenskih velikih foraminifer. Tovrstna literatura seže prav na začetek geološke znanosti in je mnogokrat raztresena v težko dostopnih in manj znanih publikacijah. Sedaj je ta velika količina podatkov, ki bi sicer ostali znani samo redkim specialistom, postala dostopna širši javnosti. Predstavlja nepogrešljivo orodje za vsakogar, ki se ukvarja s katerimkoli področjem geologije in paleontologije paleogena. Kamnine s paleogenskimi velikimi foraminiferami tvorijo marsikje pomembne kolektorje za nafto ali pa so v njih nahajališča drugih gospodarsko pomembnih surovin. Pričujoči seznam bo tako dobrodošel ne le akademskim raziskovalcem, temveč tudi tistim, ki se v praksi ukvarjajo z izkoriščanjem naravnih bogastev.
