Download or read book Biodiversity and Evolutionary Ecology of Extinct Organisms written by Rituparna Bose and published by Springer Science & Business Media. This book was released on 2012-08-11 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Increasing rate of species extinction in the present day will lead to a huge biodiversity crisis; eventually, this will lead to the paucity of non-renewable resources of energy making our Earth unsustainable in future. To save our mother planet from this crisis, studies need to be performed to discover abundant new fossil sites on Earth for continued access to oil-rich locations. Most importantly, a holistic approach is necessary in solving the present problem of biodiversity loss. This book presents newly developed quantitative models in understanding the biodiversity, evolution and ecology of extinct organisms. This will assist future earth scientists in understanding the natural and anthropogenic causes behind biodiversity crisis and ecosystem collapse. In addition, this study would be of great interest to exploration geologists and geophysicists in potentially unraveling natural resources from our sustainable Earth.

Download or read book Palaeobiology of Middle Paleozoic Marine Brachiopods written by Rituparna Bose and published by Springer Science & Business Media. This book was released on 2013-05-14 with total page 65 pages. Available in PDF, EPUB and Kindle. Book excerpt: Fossil species appear to persist morphologically unchanged for long intervals of geologic time, punctuated by short bursts of rapid change as explained by the Ecological Evolutionary Units (EEUs). Here, morphological variation in Paleozoic atrypide morphology at the subfamily level (Atrypinae and Variatrypinae) from the Silurian and Devonian time intervals in the third Paleozoic EEU (~444-359 my) were investigated using relatively new techniques of quantitative modeling. The study explains how a group of closely related taxa in atrypide subfamilies exhibit morphological conservation through time in P3 EEU within the Eastern North America region.
Download or read book Ancient Hydrocarbon Seeps written by Andrzej Kaim and published by Springer Nature. This book was released on 2022-08-30 with total page 691 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume details the function of hydrocarbon seeps, their evolution over time, the most important seep occurrences and the fauna present in ancient hydrocarbon seeps. While several publications exist that cover modern seeps and vents, fossil seeps only constitute a small component of the literature. As such, many geologists, stratigraphers and paleontologists, as well as undergraduates and graduate students, are not very familiar with ancient hydrocarbon seep deposits and their associated fauna. This text is the first to comprehensively discuss the nature of such animal groups and how to recognize them. In addition to summarizing available knowledge on these topics for specialists in the field, this book offers the background needed to be of use to students as well as the wider community of geologists and paleontologists.

Download or read book A New Silurian Llandovery Telychian Sponge Assemblage from Gotland Sweden written by Freek Rhebergen and published by John Wiley & Sons. This book was released on 2014-02-27 with total page 161 pages. Available in PDF, EPUB and Kindle. Book excerpt: A newly discovered, diverse sponge fauna of early Silurian age, is described from Gotland, Sweden. This is the first Silurian sponge assemblage known from Baltica, and the only diverse Llandoverian assemblage known worldwide. The fauna includes 20 genera and 29 species, of which three genera and six species are new. Eighteen species are new to Baltica. The fauna shows strong similarities to later Silurian assemblages in Arctic Canada, but one endemic species comprises ca. 50% of the fauna. The fauna shows that lithistid sponges recovered well from the late Ordovician extinction in some areas, and became widely spread in the early Silurian. In contrast, non-lithistid sponges like, such as hexactinellids, appear to have evolved rapidly during the Late Ordovician – early Silurian interval, and some modern groups probably originated in inshore habitats.
