Book Description
This book gives a new global perspective on the Phanerozoic timescale, by bringing together extensive Australian and overseas research on biostratigraphy, geochronology, and magnetostratigraphy. For the first time, correlations are established between Australian and European biozonal schemes for the entire Phanerozoic, by integrating local and international biozones, isotopic ages, and magnetic polarity intervals. Tie points are based on tightly constrained isotopic and biostrastigraphic ages, and this is the first compilation for the whole of the Phanerozoic to apply results from the latest isotopic dating techniques, including the high resolution ion microprobe (SHRIMP) and variants of the (superscript 40)Ar/(superscript 39)Ar method. These have radically rescaled some parts of the geological column. An Australian Phanerozoic Timescale gives the essential framework for resource exploration, geologic modelling, and reconstruction of past environments and land-sea configurations during the last 545 million years of earth history.

Book Description
Both Wallchart and Explanatory Notes are a compilation of the history and current status of the major subdivisions of the Phanerozoic Eon; they are derived from the detailed charts presented in the larger reference volume, An Australian Phanerozoic Timescale (eds. Young and Laurie, OUP, 1996).The Wallchart displays a linear timescale for the Phanerozoic taken to the level of stages; a non-linear scale for the Precambrian is included to show the fullness of geologic time. The Explanatory Notes describe briefly each time period: its history, definition of its base in terms of isotopic andbiostratigraphic data, and its subdivision into series and stages. AGSO Phanerozoic Timescale 1995 integrates standard European time units and Australian Cambrian and Ordovician stages. This scale is significant for global correlation of Phanerozoic sequences and their biotas. It will be attractiveand useful to resource exploration companies, geological surveys, university and school students, and individual professional and amateur geologists.

Book Description
The Australian vegetation is the end result of a remarkable history of climate change, latitudinal change, continental isolation, soil evolution, interaction with an evolving fauna, fire and most recently human impact. This book presents a detailed synopsis of the critical events that led to the evolution of the unique Australian flora and the wide variety of vegetational types contained within it. The first part of the book details the past continental relationships of Australia, its palaeoclimate, fauna and the evolution of its landforms since the rise to dominance of the angiosperms at the beginning of the Cretaceous period. A detailed summary of the palaeobotanical record is then presented. The palynological record gives an overview of the vegetation and the distribution of important taxa within it, while the complementary macrofossil record is used to trace the evolution of critical taxa. This book will interest graduate students and researchers interested in the evolution of the flora of this fascinating continent.

Book Description
The Geologic Time Scale 2012, winner of a 2012 PROSE Award Honorable Mention for Best Multi-volume Reference in Science from the Association of American Publishers, is the framework for deciphering the history of our planet Earth. The authors have been at the forefront of chronostratigraphic research and initiatives to create an international geologic time scale for many years, and the charts in this book present the most up-to-date, international standard, as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. This 2012 geologic time scale is an enhanced, improved and expanded version of the GTS2004, including chapters on planetary scales, the Cryogenian-Ediacaran periods/systems, a prehistory scale of human development, a survey of sequence stratigraphy, and an extensive compilation of stable-isotope chemostratigraphy. This book is an essential reference for all geoscientists, including researchers, students, and petroleum and mining professionals. The presentation is non-technical and illustrated with numerous colour charts, maps and photographs. The book also includes a detachable wall chart of the complete time scale for use as a handy reference in the office, laboratory or field. The most detailed international geologic time scale available that contextualizes information in one single reference for quick desktop access Gives insights in the construction, strengths, and limitations of the geological time scale that greatly enhances its function and its utility Aids understanding by combining with the mathematical and statistical methods to scaled composites of global succession of events Meets the needs of a range of users at various points in the workflow (researchers extracting linear time from rock records, students recognizing the geologic stage by their content)

Book Description
The print edition is published as 2 hardback volumes, parts A and B, and sold as a set. The Carboniferous was the time of the assembly of Pangaea by the collision of the Gondwanan and Larussian supercontinents, and the principal interval of the late Paleozoic ice ages. These tectonic and climatic events caused dramatic sea-level fluctuations and climate changes and produced a Carboniferous world that was diverse topographically and climatologically, perhaps only rivalled in that diversity by the late Cenozoic world. Furthermore, the Carboniferous was a time of the accumulation of vast coal deposits of great economic and societal significance. The temporal ordering of geological and biotic events during Carboniferous time thus is critical to the interpretation of some unique and pivotal events in Earth history. This temporal ordering is based on the Carboniferous timescale, which has been developed and refined for nearly two centuries. This book reviews the history of the development of the Carboniferous chronostratigraphic scale and includes comprehensive analyses of Carboniferous radioisotopic ages, magnetostratigraphy, isotope-based correlations, cyclostratigraphy and timescale-relevant marine and non-marine biostratigraphy and biochronology.
