End of an Era: New Ruling Decides the Boundaries of Earth's
History, September 22, 2009

http://www.physorg.com/news172824857.html

After decades of debate and four years of investigation an
international body of earth scientists has formally agreed
to move the boundary dates for the prehistoric Quaternary
age by 800,000 years, reports the Journal of Quaternary
Science.

The paper is:

Gibbard et al., 2009, Formal ratification of the Quaternary
System/Period and the Pleistocene Series/Epoch with a
base at 2.58 Ma. Journal of Quaternary Science.
