"A triumph of scholarship, that will serve the professsion and the public well."
Episodes, June 2005, John A. Van Couvering
"The editors have succeeded admirably in compiling a work that is dense with information but is both beautiful in layout and extremely readable...The book is a masterpiece of presentation...an amazing work that provides a new standard for both geochronology, and for committee-driven scientific project reports."
The Leading Edge, John Stockwell
An international team of over forty stratigraphic experts have helped to build the most up to date international stratigraphic framework for the Precambrian and Phanerozoic. As successor to A Geologic Time Scale 1989 by W. Brian Harland et al., it first introduces the theory and methodology behind the construction of the new time scale, before presenting the scale itself in extensive detail. A large wallchart summarising the whole time scale is included in the back of the book. This is an invaluable reference source for researchers and students.
