Felix Gradstein

Felix is Professor Emeritus at Oslo University, Norway, and visiting Research Fellow at the University of Portsmouth, United Kingdom. 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 conceming the Geologic Time Scale, geochronology in general, quantitative stratigraphy, and micropaleontology, the European Geosciences Union awarded him the Jean Baptiste Lamarck Medal in 2010. He is Chair of the Geologic TimeScale 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 coeditors and coauthors, he studies the early evolution of planktonic foraminifera.
