The Vegetation of Antarctica through Geological Time
Author: David J. CantrillPublisher: Cambridge University Press
ISBN: 113956028X
Category : Science
Languages : en
Pages : 489
Book Description
The fossil history of plant life in Antarctica is central to our understanding of the evolution of vegetation through geological time and also plays a key role in reconstructing past configurations of the continents and associated climatic conditions. This book provides the only detailed overview of the development of Antarctic vegetation from the Devonian period to the present day, presenting Earth scientists with valuable insights into the break up of the ancient supercontinent of Gondwana. Details of specific floras and ecosystems are provided within the context of changing geological, geographical and environmental conditions, alongside comparisons with contemporaneous and modern ecosystems. The authors demonstrate how palaeobotany contributes to our understanding of the paleoenvironmental changes in the southern hemisphere during this period of Earth history. The book is a complete and up-to-date reference for researchers and students in Antarctic paleobotany and terrestrial paleoecology.
Frozen in Time
Author: Jeffrey D StilwellPublisher: CSIRO PUBLISHING
ISBN: 064310402X
Category : Science
Languages : en
Pages : 249
Book Description
No other continent on Earth has undergone such radical environmental changes as Antarctica. In its transition from rich biodiversity to the barren, cold land of blizzards we see today, Antarctica provides a dramatic case study of how subtle changes in continental positioning can affect living communities, and how rapidly catastrophic changes can come about. Antarctica has gone from paradise to polar ice in just a few million years, a geological blink of an eye when we consider the real age of Earth. Frozen in Time presents a comprehensive overview of the fossil record of Antarctica framed within its changing environmental settings, providing a window into a past time and environment on the continent. It reconstructs Antarctica’s evolving animal and plant communities as accurately as the fossil record permits. The story of how fossils were first discovered in Antarctica is a triumph of human endeavour. It continues today with modern expeditions going out to remote sites every year to fill in more of the missing parts of the continent’s great jigsaw of life.
Late Cretaceous/Paleogene West Antarctica Terrestrial Biota and its Intercontinental Affinities
Author: Marcelo RegueroPublisher: Springer Science & Business Media
ISBN: 9400754914
Category : Science
Languages : en
Pages : 124
Book Description
One of the most intriguing paleobiogeographical phenomena involving the origins and gradual sundering of Gondwana concerns the close similarities and, in most cases, inferred sister-group relationships of a number of terrestrial and freshwater vertebrate taxa, e.g., dinosaurs, flying birds, mammals, etc., recovered from uppermost Cretaceous/ Paleogene deposits of West Antarctica, South America, and NewZealand/Australia. For some twenty five extensive and productive investigations in the field of vertebrate paleontology has been carried out in latest Cretaceous and Paleogene deposits in the James Ross Basin, northeast of the Antarctic Peninsula (AP), West Antarctica, on the exposed sequences on James Ross, Vega, Seymour (=Marambio) and Snow Hill islands respectively. The available geological, geophysical and marine faunistic evidence indicates that the peninsular (AP) part of West Antarctica and the western part of the tip of South America (Magallanic Region, southern Chile) were positioned very close in the latest Cretaceous and early Paleogene favoring the “Overlapping” model of South America-Antarctic Peninsula paleogeographic reconstruction. Late Cretaceous deposits from Vega, James Ross, Seymour and Snow Hill islands have produced a discrete number of dinosaur taxa and a number of advanced birds together with four mosasaur and three plesiosaur taxa, and a few shark and teleostean taxa.
Cretaceous-Tertiary High-latitude Palaeoenvironments
Author: Jane E. FrancisPublisher: Geological Society of London
ISBN: 9781862391970
Category : Science
Languages : en
Pages : 224
Book Description
High-latitude settings are sensitive to climatically driven palaeoenvironmental change and the resultant biotic response. Climate change through the peak interval of Cretaceous warmth, Late Cretaceous cooling, onset and expansion of the Antarctic ice sheet, and subsequently the variability of Neogene glaciation, are all recorded within the sedimentary and volcanic successions exposed within the James Ross Basin, Antarctica. This site provides the longest onshore record of Cretaceous-Tertiary sedimentary and volcanic rocks in Antarctica and is a key reference section for Cretaceous-Tertiary global change. The sedimentary succession is richly fossiliferous, yielding diverse invertebrate, vertebrate and plant fossil assemblages, allowing the reconstruction of both terrestrial and marine systems. The papers within this volume provide an overview of recent advances in the understanding of palaeoenvironmental change spanning the mid-Cretaceous to the Neogene of the James Ross Basin and related biotic change, and will be of interest to many working on Cretaceous and Tertiary palaeoenvironmental change.

Effects of Past Global Change on Life
Author: Panel on Effects of Past Global Change on LifePublisher: National Academies Press
ISBN: 0309552613
Category : Science
Languages : en
Pages : 267
Book Description
What can we expect as global change progresses? Will there be thresholds that trigger sudden shifts in environmental conditions--or that cause catastrophic destruction of life? Effects of Past Global Change on Life explores what earth scientists are learning about the impact of large-scale environmental changes on ancient life--and how these findings may help us resolve today's environmental controversies. Leading authorities discuss historical climate trends and what can be learned from the mass extinctions and other critical periods about the rise and fall of plant and animal species in response to global change. The volume develops a picture of how environmental change has closed some evolutionary doors while opening others--including profound effects on the early members of the human family. An expert panel offers specific recommendations on expanding research and improving investigative tools--and targets historical periods and geological and biological patterns with the most promise of shedding light on future developments. This readable and informative book will be of special interest to professionals in the earth sciences and the environmental community as well as concerned policymakers.
