Overview

Geologic Time Scale 2020 contains contributions from leading scientists, with information presented in an easy-to-understand way including numerous color charts, maps, and photographs. Including recent information from such projects as GTSNext, Earth Time Europe, and Chronos, this updated edition explains in detail how and why the time scale is being updated and offers expanded coverage of paleontology and stratigraphy. Twelve mini chapters in Geologic Time Scale 2020 address Evolution and Biostratigraphy in key (micro-) fossil groups. These chapters assist readers of the Geological Period chapters to better understand and appreciate the role played by paleontology in describing and understanding life on Earth in Deep Time. The authors of Geologic Time Scale 2020 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 chronostratigraphic standard as ratified by the International Commission on Stratigraphy and the International Union of Geological Sciences. As the framework for deciphering the history of our planet Earth, this book is essential for practicing Earth Scientists and academics.

Author Information

FELIX GRADSTEIN is Professor Emeritus at Oslo University, Norway and visiting Research Fellow, University of Portsmouth, UK. From 2000 to 2008, he was chair of the International Commission on Stratigraphy. Under his leadership major progress was made with the formal definition of chronostratigraphic units from Precambrian through Quaternary. For his fundamental work concerning the Geologic Time Scale, geochronology in general, quantitative stratigraphy and micropaleontology, the European Geosciences Union awarded him in 2010 the Jean Baptiste Lamarck Medal. He is Chair of the Geologic Time Scale Foundation and teaches courses in quantitative stratigraphy and the geologic time scale. Now that he has free time again, after completing this book with his outstanding co-editors and co-authors he studies the early evolution of planktonic foraminifera. MARK SCHMITZ is Professor of Geochemistry at Boise State University, Idaho, USA, and has extensive research interests in the development and application of radiogenic isotope geochemistry and high-precision U-Pb geochronology to problems of Earth systems evolution. He has been an active member of the Earth Time community and was co-editor and author for the Geologic Time Scale 2012. He seeks to enrich the radioisotopic calibration of the time scale through targeted dating of stratigraphically important volcanic event beds and the construction of robust chronostratigraphic models through geologic time. His extensive database with over 300 standardized radiogenic isotope ages (mainly U/Pb and Ar/Ar) is vital to this book. GABI OGG applied micropaleontology to Jurassic-Cretaceous correlations before concentrating on public outreach in geosciences. She coordinated the extensive array of graphics in this book, and is the webmaster for the Geologic TimeScale Foundation (https://timescalefoundation.org) and for the TimeScale Creator visualization and database suites (https://timescalecreator.org). In addition to co-authoring the Concise Geologic TimeScale (GTS2016) and The Geologic Time Scale (GTS2012) books, she has produced numerous posters and time scale cards for public audiences.
